5. Monitor level control knob [MON (INPUT/TRK)]

These knobs are used to select signals sent to monitor sections L and R, and to adjust the level of those signals. The following options are available.

“TRK”

The recorder output signals are sent to the monitor

 

section. As you turn the knob to the right, the signal

 

level becomes higher.

 

 

“0”

No signals are sent.

 

 

“INPUT”

Pre-fader signals* from the INPUT jacks are sent to the

 

monitor section.As you turn the knob to the left, the signal

 

level becomes higher.

 

 

* Pre-fader signal: Input signals before reaching the input faders

6. Equalizer control knobs [EQ (HIGH/MID/LOW)]

These knobs are used to adjust tonal quality of the signals routed to the channel faders. The following settings are available.

“HIGH”

Signals with a frequency of 12kHz will be boosted/cut up

 

to +/-15dB.

 

 

“MID GAIN”

The frequency range selected via the MID SHIFT knob

 

(200Hz-5kHz) will be boosted/cut up to +/-15dB.

 

 

“MID SHIFT”

Use this setting to select a frequency range to boost or

 

cut using the MID GAIN knob. You can set the frequency

 

in the range of 200Hz-5kHz.

 

 

“LOW”

Signals with a frequency of 80Hz will be boosted/cut up

 

to +/-15dB.

 

 

 

 

7. AUX send knobs [AUX (AUX 1/AUX 2)]

These knobs are used to select whether the channel fader signals are output from the AUX SEND 1 jack or AUX SEND 2 jack, and to adjust the level of those signals. That is, the signals selected and adjusted via these knobs will be sent from the AUX SEND jack 1 or 2 to an external device, such as an effect unit.

“AUX 1”

Signals are sent to theAUX SEND jack 1. Turning the knob

 

to the left will increase the output level.

 

 

“0”

No signals are sent.

 

 

“AUX 2”

Signals are sent to theAUX SEND jack 2. Turning the knob

 

to the right will increase the output level.

 

 

Names and Functions

8. AUX return knobs [AUX RTN (1, 2)]

These knobs allow you to adjust the input level of processed signals from a connected external effect unit.

AUX RTN 1

These knobs enable you to adjust the input level of

 

processed signals from an external effect unit connected

 

to the AUX RTN jack 1. The level of both signals input to

 

AUX RTN 1 L/MONO and R will be adjusted equally.

 

 

AUX RTN 2

These knobs enable you to adjust the input level of

 

processed signals from an external effect unit connected

 

to the AUX RTN jack 2. The level of both signals input to

 

AUX RTN 2 L/MONO and R will be adjusted equally.

 

 

9. Monitor master knob [MONITOR SECTION (MASTER)]

This knob allows you to adjust the final level of monitoring signals, that is, the headphone volume and the level of signals output from the MON OUT L/R jacks.

10.Monitor select switch [SELECTOR (L/R, L/R+MON, MON)]

This switch allows you to select a signal to be routed to the MON OUT L/R and PHONES jacks. The following options are available.

“L/R”

This selects signals output from the STEREO OUT L/R

 

jacks (stereo bus L/R signals).

 

 

“L/R+MON”

This selects both signals output from the STEREO OUT

 

L/R jacks and signals routed to channel monitor buses

 

L/R.

 

 

“MON”

This selects signals routed to channel monitor buses L/

 

R.

 

 

11. Master fader [L/R]

The master fader allows you to adjust the level of signals output from the STEREO OUT L/R jacks (stereo bus L/R output signal). The fader setting will affect the level of recorder input signals.

12. Input level switches [LEVEL (H/M/L)]

Set these switches to appropriate positions according to the output level of the devices connected to input jacks 3 and 4 (the phone jacks on the front panel or the XLR connector on the rear panel).

Connect a microphone or other low-output device to input jacks 3 and 4 (on the front panel or rear panel) that have the input level switch. Refer to the example below.

<Example>

“L (-50dB)”

Set the switch to this position when you connect

 

a microphone.

 

 

 

“M (-30dB)”

Set the switch to this position when you connect

 

a single-coil or humbucking type electric guitar or

 

bass.

 

 

 

“H (-10dB)

Set the switch to this position when you connect

 

a keyboard or drum machine.
