2.Input Gain Control

This control sets the input signal level coming from Main In.

3.Input Level Meter

This meter tells you the level of the main input signal coming from Main/Direct In, and the range goes from -24dBu to +18dBu.

4.Aux In Input

The Aux In Input is used to feed the further input signal, which can be mixed with the Main/ Direct In signal via Balanced Control.

5.L Mute Switch

The Left input signal will be muted if this switch is activated.

6.R Mute Switch

10.Balanced Control

This control is used to set the proportion between the signal coming from Aux In Input and Main/Direct In Input.

11.Output Gain Control

This control is used to adjust the output level of the individual channel.

12.Output Level Meter

This 4-digit meter tells you the level of the output signal, and the range goes from -24dBu to +12dBu. In case of the Clip LED lights up, please turn down the Input Gain Control or/and the individual Output Gain Control to avoid any distortion.
