Introduction.
Thank you for purchasing the Yamaha EMX5000-20/EMX5000-12 Powered Mixer.
In order to take full advantage of the EMX5000-20/EMX5000-12 and enjoy long, trouble-free performance, please read this owner's manual carefully, and keep it in a safe place for future reference.


Features.
The EMX5000-20/EMX5000-12 provides versatile inputs, such as two stereo input channels and two stereo sub inputs, as well as 16 (EMX5000-20), 8 (EMX5000-12) monaural input channels compatible with mic/line signals. The mixer also has ample power, with a maximum output of 500 W + 500 W (1000 W with bridge connection), and is suitable for a wide range of applications from installed systems to small-scale PA systems.
A two-channel power amp is built-in. The signals output to speakers can be selected as stereo (ST L-R), AUX + monaural (AUX 1- MONO), two AUX (AUX1 - AUX2) or monaural (bridge connection).
In addition to the speaker output jacks, two stereo output channels for line-level signals, two AUX output channels, two effect outputs, and one monaural output are provided. You can easily expand the system by adding a power amplifier or powered speakers.
The EMX5000-20/EMX5000-12 also has a PHONES jack, which is very useful for checking the sound. You can monitor only a specific channel or bus signal through the headphones.
Each amp contains a limiter circuit to prevent distortion due to excessive input levels.
A maximum output select switch lets you switch the maximum output of the amp between three levels. This lets you adjust the maximum output of the internal power amp as appropriate for the size of the room or the input capacity of the speakers.
Two multi-effect units are built-in, each providing sixteen types of effect equivalent in quality to the acclaimed Yamaha SPX series of multi-effect units. The effects can be used to add reverb or ambience to vocals or instruments. The sixteen types (provided by each of the two effect units) include TAP DELAY, which lets you easily adjust the delay time.
The EMX5000-20/EMX5000-12 has implemented "EEEngine", Yamaha's epochal amp drive technology to create an unrivaled high-efficiency drive. The EEEngine's energy-saver/low-heat-generation design has reduced power consumption to 50% or less, and reduced heat generation to 35% or less (in field applications, compared to Yamaha's previous models), and has lead to a reduction in energy cost and to less-restrictive installation requirements related to heat generation.

EMX5000-20/EMX5000-12 Quick Guide.
The following steps (1 to 5) explain the basic connection and operation of the EMX5000-20/EMX5000-12.
Also, please read "Front and Rear Panel" and "Basic Operation" following this Quick Guide section to learn more about using the EMX5000-20/EMX5000-12.

STEP 1. Connection.
Connecting speakers.
Using speaker cables, connect each speaker to the SPEAKERS A jack and to the B jack in the SPEAKERS jack section on the rear panel of the EMX5000-20/EMX5000-12.
(Figure)
In the example shown by the above diagram, two main speakers are connected (one each to left and right) in stereo. For other connection examples, refer to pages 20 to 21.
You may connect to either of the two jacks on the speakers.
Be sure to use a cable designed for speaker connection.
Speakers with a Speakon connector can also be connected using a Speakon cable. In this case, use the SPEAKERS 1 jacks to output the signal from the EMX5000-20/EMX5000-12.
When connecting a Speakon connector to the EMX5000-20/EMX5000-12, be sure to turn the plug to the right to lock the connection after inserting the plug.

Never connect the speakers in the manner shown below. Otherwise, the EMX5000-20/EMX5000-12's built-in power amplifier will be damaged.
(Figure)

Setting the power amplifier mode.
Set the power amp select switch (located on the right corner on the panel) to ST L-R.

This quick guide explains how to connect one main speaker each to left and right for stereo operation. If the power amp select switch is set to the ST L-R position as shown here, the stereo R signal will be output from the SPEAKERS A jacks, and the stereo L signal from the SPEAKERS B jacks.
Refer to pages 14, 19, 20 for other connections and power amp select switch settings.

Connecting a microphone.
Make sure that the power is turned off to the EMX5000-20/EMX5000-12.
Connect mics to channels 1 to 16 (EMX5000-20) or 1 to 8 (EMX5000-12), using the INPUT A jacks if the mic has an XLR plug, or the INPUT B jacks if the mic has a phone plug.

Using a condenser microphone.
Turn on the PHANTOM switch (located in the upper center corner on the panel).
The PHANTOM switch supplies phantom power to all channel inputs at once (EMX5000-20: 1 to 8 and 9 to 16, EMX5000-12: 1 to 8), so mics other than condenser mics must be connected to the INPUT B jacks.
Do not connect or disconnect a condenser microphone while the power to the unit is on and the PHANTOM switch has been turned on.

Connecting a CD player, MD player, and/or cassette deck.
Connect a CD player or MD player to the 2TR IN jacks. Refer to the operation manual of the corresponding device for more information on the input and output of the device.
To connect a second player, use the LINE jack.
Connect a recorder to the REC OUT jacks.

Connecting an electric acoustic guitar or electric bass.
Connect electric/acoustic guitars or electric basses via an effect processor or direct box to the INPUT B jack.
You cannot use the INPUT A jack and the INPUT B jack for the same channel at the same time. If a microphone has already been connected to the INPUT B jack of a channel, you cannot connect the effect unit to the INPUT A jack of the channel.

Connecting an electronic musical instrument.
To the EMX5000-20/EMX5000-12's LINE or ST SUB IN jacks, you can connect an electronic musical instrument such as a synthesizer, drum machine, signal processor connected to an electric guitar, etc. Refer to the diagram below to make a stereo connection from the output jacks (such as L/MONO and R) of an electronic musical instrument to the LINE or ST SUB IN jacks in stereo.

Control panel.
Channel control section.
In this section, you can adjust equalization (frequency response), volume level, effect and AUX output levels for the input signal of each channel.

1. 26 dB pad switch
This switch attenuates the input signal by 26 dB. 
Attenuation is on when the switch is pressed inward.

2. GAIN control
Use this knob to adjust the sensitivity according to the input signal level, so that the input level is appropriate.
For the best balance of S/N ratio and dynamic range, adjust this knob so that the peak indicator (10)lights occasionally.
* When the knob is at the "marked" position, the input sensitivity will be +4 dB.

3. (High pass filter) switch
This is an on/off switch for the high-pass filter.
The high-pass filter is on when the switch is pressed inward, and the frequency region below 80 Hz will be attenuated at 18 dB/octave.

4. Equalizer controls (HIGH, MID, LOW)
This is a 3-band equalizer that adjusts the high frequency range, mid frequency range, and low frequency range of each channel.
When the HIGH and LOW knobs are in the "marked" position, the high and low ranges will have a flat response. Turning a knob toward the right will boost the corresponding frequency range, and turning it toward the left will cut it.
For the mid range, use the upper MID knob to specify the center frequency of the range, and use the lower knob to set the amount of boost or cut that will occur. The frequency response is flat when the lower knob is set to the "marked" position.
Turning the lower knob toward the right will boost the corresponding frequency range, and turning the knob toward the left will cut it.
The base frequency (or center frequency), range of boost or cut, and equalizer type of each band are as follows:
HIGH:	10kHz, plus/minus 15 dB, shelving type
MID:	250Hz to 5kHz, plus/minus 15 dB, peaking type
LOW: 	100Hz, plus/minus 15 dB, shelving type

5. AUX1, AUX2 controls / POST switches
These knobs adjust the level at which the input signal will be sent to the AUX1 and 2 buses.
Nominal level is when the knob is set to the "marked" position. The position from which the signal is sent can be set by the POST switch to either pre-fader (before the channel fader (13)) or post-fader (after the channel fader (13)). When the switch is pressed inward, post-fader is selected.
The signal will be output from the AUX1 and 2 buses to the AUX SEND 1 and 2 jacks of the input/output section, and can be sent to external monitor amps or powered speakers.

6. EFF 1, 2 controls (EFFECT)
For each channel, these control the amount of signal that is sent to the EFFECT 1, 2 buses.

Input/output panel.
1. Channel input jacks (INPUT A, INPUT B)
EMX5000-20: 1 to 16, EMX5000-12: 1 to 8.
By using the GAIN control (control panel (2)) you can connect any of the jacks to a wide range of sources, from mics to line-level devices (including synthesizers and rhythm machines).
The INPUT A jacks can provide +48V phantom power, allowing you to use condenser microphones.
The nominal input level is from minus 16 dB to minus 60 dB when the 26 dB pad switch (control panel (1)) is off, or from +10 dB to minus 34 dB when it is on.
Both INPUT A and B are balanced.
They are compatible with microphones of output impedance 50 to 600 ohm or line level devices of 600 ohm.
Pin connections for the jacks are as follows:

INPUT A jacks (XLR type)	I
Pin 1: ground 	
Pin 2: hot (+) 	
Pin 3: cold (-)	

NPUT B jacks (TRS phone jacks) *
Sleeve: ground
Tip: hot (+)
Ring: cold (-)
* You can also connect a normal unbalanced phone plug.

Note: 
It is not possible to simultaneously use both the INPUT A and B inputs of a given channel. For each channel, use only one of the inputs as appropriate for the input source.
Phantom power is switched on/off simultaneously for channels 1 to 8 and 9 to 16 (EMX5000-20), 1 to 8 (EMX5000-12). For this reason, devices (in particular, unbalanced devices) other than condenser microphones must be connected to the INPUT B input jacks of channels or channel 17/18 to 19/20 (EMX5000-20), 9/10 to 11/12 (EMX5000-12) input jacks if the PHANTOM +48V switch (control panel (3)) is on.

2. INSERT I/O (insert) jacks
These are TRS phone jacks that enable you to insert an external effect processor, such as a compressor/limiter, between the equalizer and fader of input channels. These connections require a special "Y" cable, such as shown in the following diagram. The nominal input/output levels are 0 dB.

This switch turns on/off the power to the EMX5000-20/EMX5000-12.
Note: 
Before you turn the power of the
EMX5000-20/EMX5000-12 on or off, the faders and controls in the master section of the control panel must be lowered to the minimum position.

3. SPEAKERS (speaker output) jacks
These jacks are used to connect speakers.
Jacks 1 are Speakon-type connectors. Use only Neutrik NL4FC plugs for connecting Speakon connectors.
Jacks 2 are 1/4" phone jacks. The setting of the control panel power amp select switch (35) will determine the signal that is output to these jacks, and the number and appropriate impedance of the speakers that can be connected.


Installation/Connections.
Installation.
The EMX5000-20/EMX5000-12 uses a forced cooling system with air intake on the right side and exhaust on the rear. When placing the unit, make sure that the cooling ports are not obstructed.

Connection.
When connecting various devices, make sure the cables and plugs have the correct rating.
Be sure to use cables designed for the purpose when you connect speakers to speaker jacks.

Connecting main speakers.
There are three ways in which speakers can be connected to the EMX5000-20/EMX5000-12.
The speaker impedance requirement varies depending on how you connect the speakers. Refer to the diagrams below to make sure the speaker impedance will not be lower than the specified value.

When the power amp select switch is set to ST L-R, AUX 1-MONO or AUX 1-AUX 2:
Select either one or two speakers each to jacks A and jacks B. Make connections to either jacks 1 or 2, depending on the type of speaker cable you are using.
When the power amp select switch is in the ST L-R position, the signals of the stereo L and R bus will be output from the speakers connected to jacks A and B respectively.
When this switch is in the AUX 1-MONO position, the signals of the AUX 1 bus and the STEREO bus will be combined and output as a monaural signal from the speakers connected to these jacks.
When this switch is in the AUX 1-AUX 2 position, the signals of the AUX 1 bus and AUX 2 bus will be output from the speakers connected to these respective jacks.

Two channel connections.
Use speakers with an impedance in the range of 4 to 8 ohms if you are connecting only one speaker to each set of outputs. A maximum output of 500W + 500W will be obtained when 4-ohm speakers are used.

Two channel parallel connections.
If you connect two speakers in parallel to the SPEAKERS A and SPEAKERS B jacks, use speakers with an impedance in the range of 8 to 16 ohms. A maximum output of 500W + 500W will be obtained when 8-ohm speakers are used.

When the power amp select switch is set to MONO BRIDGE:
Bridge connection.
Connect only one 8 to 16 ohm speaker to the A1 jack. The speaker will output the combined monaural signal of the STEREO bus. A maximum output of 1000 W will be obtained when an 8-ohm speaker is used.
If you are inputting a signal from the P.AMP IN jack, input it to P.AMP IN jack A.
Caution:
When using a bridge connection, do not connect a speaker to the B or A 2 jack.

Basic operation.

Connecting microphones and instruments.
1 	Before connecting mics or instruments, make sure that the power of all equipment (where applicable) is turned off.
Also make sure that each channel fader and the faders in the master section are turned down. Check to see if the Power amp select switch on the control panel is set to ST L-R.

2 	Connect cables to your mics and instrument, and insert the other end of the cables firmly into the appropriate INPUT A/B jacks (EMX5000-20: channels 1 to 16, EMX5000-12: channels 1 to 8) or the 17L/18R, 19L/20R (EMX5000-20), 9L/10R, 11L/12R (EMX5000-12) jacks.
Note: 
You cannot use channel 1 to 16 (EMX5000-20), 1 to 8 (EMX5000-12) INPUT A and B jacks at the same time.

3 	Turn on the power to the peripheral devices, then turn on the power to the EMX5000-20/EMX5000-12.
Note: 
When turning the power off, reverse this sequence.

4 	While speaking into the mic (or while playing the instrument), adjust the channel GAIN control so that the channel PEAK indicator lights occasionally at the maximum volume.

5 	Raise the ST OUT fader in the master section to the "10" position, and while speaking into the mic (or while playing the instrument), adjust the channel fader so that the 0 LED of the peak level indicator lights occasionally. Use the LEVEL control to adjust the maximum level of the speakers.

6 	If you wish to adjust the tone of each channel, rotate the equalizer controls as desired.

7 	Use the graphic equalizer and the ST fader in the master section to adjust the overall volume and tone.
Note: 
The volume level is affected by the settings of the channel equalizers and the graphic equalizer. When you set the equalizers, check the peak level indicator and adjust the ST fader if necessary.

Using the digital effect.
The EMX5000-20/EMX5000-12 has a built-in digital effect, allowing reverberation or ambiance to be added to vocals or instrumental sounds.

1 	Connect a mic or instrument to the desired channels, and adjust the volume and tone.

2 	Press the ON switch of the digital effect section.

3 	Use the PROGRAM selector to select the type of effect you wish to apply.

4 	Raise the EFF 1 (or EFF 2) control of the channels to which you wish to apply the digital effect.

5 	Use the EFFECT 1 (or EFFECT 2) RTN fader of the digital effect section to adjust the level of the effect sound.
Note: 
You can send the effect sound to the AUX 1/2 bus by raising the AUX 1/2 control in the digital effect section. If the effect sound is distorted even though the ST control and the AUX 1/2 controls in the digital effect section are turned all the way down, lower the EFF 1 (or EFF 2) controls of the digital effect section.

6 	Adjust the PARAMETER control of the digital effect section to the desired level.
Note: 
The setting of the AUX 1/2 fader in the master section does not affect the internal effect.

Example setups.
This section provides some ways in which the EMX5000-20/EMX5000-12 can be used, and explains connections and operation.

As a conference/entertainment hall sound system.
Here is an example of using the EMX5000-20/EMX5000-12 as a conference or entertainment hall sound system.
(Figure)
Main speakers: to SPEAKERS jacks
Microphone: to Channel input jacks (INPUT A)
CD player: to LINE (stereo) input jacks
Cassette deck (for paly back): to LINE (stereo) input jacks
Cassette deck (for recording): to REC OUT jacks

Connections.
Connect mics to channel inputs 1 to 8.
A CD player/cassette deck can also be connected to the input jacks of channels 17/18 and 19/20 (EMX5000-20), 9/10 and 11/12 (EMX5000-12).
To record a meeting or a party, connect the REC OUT jacks of the EMX5000-20/EMX5000-12 to the input jack of a recording cassette deck, and to monitor the recording on the EMX5000-20/EMX5000-12, connect the 2TR IN jacks of the EMX5000-20/EMX5000-12 to the output of the recording cassette deck.
Connect the main speakers to the SPEAKERS A and B jacks, and set the Power amp select switch to ST L-R.

Playing back a CD player.
1 	Turn on the power to the peripheral devices, then to the EMX5000-20/EMX5000-12.
2 	Start playback on the CD player. Use the GAIN control of channel 17/18 (EMX5000-20), 9/10 (EMX5000-12) so that the PEAK indicator below the GAIN control will light occasionally. Then, raise the ST OUT fader to the "0" position, and adjust the channel 17/18 (EMX5000-20), 9/10 (EMX5000-12) fader so that the 0 LED of the peak indicator will light occasionally.
3 	As appropriate for the size of the room, use the maximum output select switch to adjust the volume (maximum output).


As a band PA.
Here is an example of using the EMX5000-20/EMX5000-12 as a small PA for a band. In this example, the monitor speakers are being sent a mix that is independent of the MAIN speaker mix. An external effect such as delay or reverb is also being used.
(Figure)
Main speakers: to a SPEAKER jack
Monitor speakers: to a SPEAKER jack
Microphone: to Channel input jacks (INPUT A)
Bass guitar: to a Channel input jacks (INPUT B) via D.I. (Direct box, effect unit, pre-amp, etc.)
Guitar : to a Channel input jacks (INPUT B) via Effect unit
Effect processor: to ST SUB IN jacks
Keyboard: to LINE (stereo) input jacks

Connections.
Connect mics or instruments, such as keyboards, to channel input jacks 1 to 20 (EMX5000-20), 1 to 12 (EMX5000-12).
Connect the main speakers to the SPEAKERSB 1/2 jacks, and connect the monitor speakers to the SPEAKERS A 1/2 jacks. Set the Power amp select switch to "AUX 1 - MONO."
If you use an external effect such as delay or reverb, connect the EMX5000-20/EMX5000-12's EFFECT SEND jack to the input jack of the external effect, and connect the output jack of the external effect to the EMX5000-20/EMX5000-12's ST SUB IN 1.
Note: 
If you are using an external effect, we recommend that you turn down all the EFFECT controls of the digital effect section.
You can connect the output of an external effect to channels 17/18 and 19/20 (EMX5000-20), 9/10 and 11/12 (EMX5000-12) to apply the equalizer to the effect return signal. However in this case, make sure that the EFF 1 (or EFF 2) controls are turned all the way down for the channels into which the effect sound is being input. If the EFF 1 (or EFF 2) controls are raised, feedback will occur, and your speakers may be damaged.

Sending an independent mix to the monitor speakers.
1 	Set the AUX 1 fader to the "0" position.
2 	Raise the AUX 1 controls for the channels that you wish to hear from the monitor speakers. Turn the AUX 1 POST switch off, in the unpressed (pre-fader) position.
Note: 
The AUX controls are not affected by the level settings of each channel. This allows you to create a mix that is independent of the main speakers.

3 	Use the AUX 1 OUT fader of the master section to adjust the overall volume.

Using an external effect processor.
You may sometimes want to use an external effect processor.
Follow the steps below.
1 	Raise the EFF 1 (or EFF 2) controls for the channels to which you want the external effect to be applied.
2 	Adjust the level of the signal output to the external effects processor so that the sound will not be distorted at the input of the external effects processor.
3 	Use the control of the ST SUB IN channel to which the processed signal is input from the external effects processor to adjust the level of the effect sound.


Using a subwoofer.
Here is an example of using a subwoofer in the speaker system.
If you are using a sub-woofer, press the LPF ON/OFF switch (located in the lower right of the EMX5000-20/EMX5000-12) to send the low-range signal to the sub-woofer. The frequency range below the frequency specified by the control knob (80 to 120 Hz) will be output to the sub-woofer.

Installing an optional rack mount kit.
By using the RK124 rack mount kit, you can install the EMX5000-12 in a rack.
Before you rack-mount the EMX5000-20/EMX5000-12, make sure that sufficient ventilation will be maintained. (Never install the unit in a sealed rack.)
If you are going to install multiple devices including the unit in a rack, keep a 1U space or more between the devices. Use a blank panel with holes for ventilation if you wish to insert a panel between the devices.
You will need a 13U space to install the rack mount.

Attaching the rack mount hardware.
1. Remove the side panel together with the six screws indicated by arrows in diagram 1 below.
2. Fasten the rack mount hardware using screws at the locations indicated by arrows in diagram 2-1 or 2-2.
The height at which the panel (on which the knobs and faders are located) will be mounted is determined by the set of holes that you use to fasten the rack mount hardware.
3. Attach the rack mount hardware to the other side in the same way.
