2 − Names and Functions of Parts

Front panel

1STANDBY/ON switch, indicator

Use this switch to turn the power ON and to put the unit in standby. When ON, the STANDBY/ON indicator lights green.

2USB indicator

Lights up orange to indicate a valid USB connection to the host computer.

3PHANTOM switches

Use these switches to set whether or not +48 V phantom power is provided to the MIC IN jacks (1-4, 5-8).

Each switch controls four input channels. Phantom power is on when the button is pushed in.

	CAUTION
••	Before turning these switches ON or OFF, turn the output
	volume down using the PHONES and MONITOR knobs.
	Depending on the mic, loud noises might be produced
	and damage could be caused to equipment and people’s
	hearing.
••	Do not connect or disconnect a mic with an input when its
	switch is ON.
••	Turn a switch ON only when connecting a condenser
	microphone that requires phantom power.
••	Do not supply phantom power to an unbalanced dynamic
	microphone.
••	Some ribbon mics can be damaged by phantom power. If
	unsure, do not supply phantom power to a ribbon mic.

4MIC IN (balanced) jacks

These are XLR balanced analog mic input jacks. Use the Gain knobs to adjust the input gain level.

(1: GND, 2: HOT, 3: COLD)

6Gain knobs and OL indicators (1-10)

Adjust the gain level for Inputs (1-10) individually. The adjustable range is from –2 dBu to –58 dBu for Mic Inputs (1-8), from +4 dBu to –42 dBu for Line Inputs (9-10), and from –6dBV to –52dBV for Guitar Inputs (9-10).

The OL (overload) indicators light when an input signal is close to distortion (when –2 dBFS is exceeded).

7MONITOR knob

Adjusts the level of signals output from the MONITOR L/R jacks on the rear panel.

8MIX knob

Controls the balance of the signal sources being output from the PHONES jack and the MONITOR L/ R jacks. With this knob turned to the far left, the unit will output the signal input from the MIC IN (1-8)jacks and LINE IN (9-14)jacks. With this knob turned to the far right, the unit will output the signal received from the computer via USB.

9PHONES jack and knob

Use this standard stereo phone jack to connect stereo headphones. This jack outputs the same signal that is output from the MONITOR L/R jacks.

Use the PHONES knob to adjust the headphones output level.

CAUTION

Turn the PHONES knob to the minimum volume before connecting headphones. Failure to do so could cause sudden loud noises and damage hearing, for example.

5GUITAR (unbalanced)/LINE IN (balanced) jacks and switches

These jacks (9-10) are standard TRS analog input jacks. When the switch is pressed in, the corresponding jack functions as an unbalanced guitar input (GUITAR).

When the switch is out, the corresponding jack functions as a balanced input (LINE IN). Use the corresponding gain knobs to set the gains of the inputs.

(Tip: HOT, Ring: COLD, Sleeve: GND)
