About this manual (two types of files):
- A text file named "00_Model Name.txt":
  This file is the text of the entire manual.
- Other text files, which have been named "Number_Chapter Name.txt" (e.g., "01_Introduction.txt", "02_Contents.txt" etc.):
  The manuals are divided into separate files for every chapter.

Controls and Functions
(Figure)

1	Mic/Line input jacks (channels 1 to 4)
Connect microphones, guitars, electronic musical instruments or audio devices. Channels 3 and 4 provide combo jacks that support both XLR and phone plugs.

XLR
Phone

2	[(OFF) MIC/(ON) LINE] switches (channels 1 to 4)
For low-level signals (including microphones), set the switch to the "(OFF) MIC" position. For high-level signals (including electronic instruments and audio devices), set the switch to the "(ON) LINE" position.

3	[Hi-Z] switch (channel 4)
This switch is used when connecting a device directly to the mixer without a DI (direct injection box) — for example, instruments with passive pickups, such as an acoustic-electric guitar or electric bass without battery. This function is effective only for the phone jack input.

4	[LINE] input jacks (channels 5/6, 7/8, 9/10)
Connect line-level devices such as electronic instruments, acoustic-electric guitars, CD players, and portable audio players. These jacks support phone, RCA-pin, and stereo-mini plugs.

Stereo-mini

NOTE	For the channel 7/8 input, if both phone and RCA-pin jacks are used at the same time, the phone jack will take priority. For the channel 9/10 input, if both phone and stereo-mini jacks are used at the same time, the stereo-mini jack will take priority. The signal from the device connected to another jack will be muted.

5	[MONITOR OUT] jacks
These are for connection to a powered speaker for monitoring purposes, and output a mix of the signals from channels 1 to 9/10. You can adjust the output level using the [MONITOR OUT] control 11. If only the [L (MONO)] jack is used, the signals from the L and R channels are mixed and output.

6	[SUBWOOFER OUT] jack
This is for connection to a powered subwoofer, and outputs a mono signal. If this jack is in use, the low frequencies below 120 Hz to the [SPEAKERS L/R] jacks will be cut. The output level is linked to that of the [MASTER LEVEL] control (22).

7	[REVERB FOOT SW] jack
This is for connection to an unlatched-type footswitch such as the Yamaha FC5 — useful for solo performers, since you can toggle the reverb on and off as needed with your foot.

8	[SPEAKERS L/R] jacks
Use commercially available speaker cables to connect the speakers.

9	[IMPEDANCE SELECT] switch
Set this switch to match the impedance of the connected speakers. If you are unsure of the impedance of the connected speakers, set this switch to "4ohm". Changing this setting changes the maximum output from the amp and changes the conditions for which the [LIMITER] LED comes on.
NOTICE
Make sure the power switch is off before changing the setting of this switch.
Setting this switch incorrectly could result in damage to the mixer/your speakers.

10	[PHANTOM (CH1/2)] switch/LED
When this switch is on, the LED lights indicating that phantom power is available for channels 1 and 2. Turn this switch on to supply power to condenser microphones or a DI (direct injection box).
NOTICE
Follow the important precautions below, in order to prevent noise and possible damage to external devices and the mixer when you operate this switch.
Be sure to leave this switch off if you do not need phantom power, or when you connect a device that does not support phantom power to channels 1 and 2.
Do not connect/disconnect a cable to/from channel 1 or 2 while this switch is on.
Turn the [LEVEL] control of channels 1 and 2 to the minimum before operating this switch.

11	[MONITOR OUT] control
Determines the signal level output from the [MONITOR OUT] jacks (5). The [MASTER LEVEL] control does not affect the [MONITOR OUT] signal.

12	Equalizer controls [HIGH, MID, LOW]
The equalizer shapes the [HIGH], [MID], and [LOW] audio frequencies. Turning the control to the right amplifies (boosts) the corresponding frequency band, while turning it to the left attenuates (cuts) the band. Setting the control to the "TRIANGLE" position produces a flat response in the corresponding band.

13	[REVERB] button/LED
When this button is on, the LED lights indicating that you can apply reverb. This button is off when you turn on the mixer. (Unlike other switches, this button cannot be locked.)

14	REVERB [TYPE/TIME] control
Determines the reverb type and its length. Turning the control to the right lengthens the time of the selected reverb type.
"HALL": 	Simulated reverb of a large space, such as a concert hall.
"PLATE": 	Simulated metal plate reverb, producing a more hard-edged and bright sound.
"ROOM": 	Simulated acoustic ambience of a small room.
"ECHO":	Echo effect suitable for vocals.

15	[REVERB] controls (channels 1 to 4)
Determines the amount of reverb for each channel when the [REVERB] button (13) is on.

16	[(OFF) STEREO /(ON) MONO] switches (channels 5/6, 7/8, 9/10)
Setting the switch to "(OFF) STEREO" will assign the signals from the L and R channels to each left and right speaker and output each signal. Setting the switch to "(ON) MONO" will mix the output of different L and R sources to output the same signal to both the left and right speakers. For keyboards with mono output, guitars, or other non-stereo sound sources, when the switch is set to "(ON) MONO", the stereo jacks can be conveniently used as multiple mono jacks.

17	Level meter
The level meter shows the level of output signal from the [SPEAKERS L/R] jacks.
NOTICE
If used at a high volume so that the [LIMITER] LED flashes continuously, the internal power amplifier section is being excessively overloaded and may malfunction. Reduce the output level with the [MASTER LEVEL] control so that the indicator flashes only briefly on the highest transient peaks.

18	[POWER] LED
This LED lights when the power is turned on by pressing the power switch.

19	[FEEDBACK SUPPRESSOR] switch/LED
When this switch is on, the LED lights indicating that feedback is automatically suppressed. (This utilizes a seven-band notch filter. When this switch or the power switch is off, the notch filter will be reset.)

20	[LEVEL] controls
Use these controls to adjust the volume for each channel. To reduce noise, set any [LEVEL] controls on unused channels to the minimum.

21	[MASTER EQ] control
Use this control to adjust the overall sound frequency balance. The center position "MUSIC" is a basic setting and if you turn the control to the left, this creates an optimum setting for speech, cutting unneeded low range frequencies. If you turn the control to the right, it creates an optimum setting for playback of sound sources, since the low range is boosted. If you turn the control further to the right, the [BASS BOOST] LED lights indicating that the bass boost function is active, giving you an even more powerful bass tone.

22	[MASTER LEVEL] control
Determines the volume of the signal output from the [SPEAKERS L/R] and [SUBWOOFER OUT] jacks. This allows you to adjust the overall volume without changing the relative volume balance among the various channels.

23	Vents
There are vents located on both sides of the mixer, and a cooling fan is installed on the exhaust side. Do not block the vents on either side when using the mixer.

24	[AC IN] jack
Connect the included power cord here.

25	(Power) switch
For turning the power of the mixer on and off.
NOTICE
Rapidly turning the mixer on and off in succession can cause it to malfunction. After turning the mixer off, wait for about 10 seconds before turning it on again.
