Front Panel

1 [INPUT 1 GAIN] knob

Adjusts the input signal level of the [MIC/LINE 1] jack.

2 [MIC/LINE 1/2] jacks

For connection to a microphone or digital instrument.

This jack can be connected to both XLR-type and

phone-type (balanced/unbalanced) plugs

. The XLR-

type is set to the optimum level for microphone

connection and phone type is for line connection.

Plug types

3 [PEAK] indicator

Lights up according to the input signal. Lights up

when the input signal is 3 dB below the clipping level.

4 [+48V] indicator

Lights up when the [+48V] switch (phantom power) is

turned on.

5 [USB] indicator

Lights up when the power is turned on. This flashes

continuously if a connected computer or iPad does not

recognize the device, or if the power supply voltage

falls below the standard level.

6 [INPUT 2 GAIN] knob

Adjusts the input signal level of the [MIC/LINE 2] jack.

7 [INPUT 2 HI-Z] switch

Switches the input impedance (on O/off N). Turn this

switch on when connecting high impedance

instruments, such as an electric guitar or electric bass,

directly to the [MIC/LINE 2] jack. When you turn this

switch on, use an unbalanced phone plug for

connection between the instruments and the

[MIC/LINE 2] jack. If you use a balanced phone plug,

this device will not work correctly.

CAUTION

To protect your speaker system, leave the monitor

speakers turned off when turning the [INPUT 2 HI-Z]

switch on/off. It’s also a good idea to turn all output level

controls down to their minimum. Neglect of these

precautions may result in loud noise bursts that may

damage your equipment, your ears, or both.

NOTICE

Do not connect or disconnect any cables while turning on

the [INPUT 2 HI-Z] switch. Doing so can damage the

connected device and/or the unit itself.

HINT

Setting optimum recording levels

Adjust the gain knobs so that the [PEAK] indicator

flashes briefly at the loudest input volume.
