You can connect a foot switch with two-conductor (Tip/Sleeve) plug to this 1/4-inch (6.5mm) jack. (optional and not
included with ACTIVE-1*) Depressing the foot switch will activate the Talk Back system.
* A momentary PRESS-AND-HOLD type of foot pedal is commonly used with electronic musical keyboards.

Front Panel
Switches
Use these switches to select input signal you wish to monitor.
Headphone Amplifiers
There are two independent headphone ampliers provided on the ACTIVE-1. Each with its own volume control

Dim Switch
Activate this switch to decrease the level of the outputs by 20db. The DIM feature effectively reduces the output
signal and therefore the listening level to allow discussion in the control room without having to change the position
of the volume knob.
Mute Switch
Activate this switch to prevent signal output.
Mono Switch
Activate this switch to listen to the audio outputs in monophonic mode. This combines the stereo audio signal into
a monophonic signal, which is useful when checking for any phase cancellation issues in the stereo signal.
Volume Control
As it is an ACTIVE device, the ACTIVE-1’s Volume control, controls an electronic circuit, which in turn adjusts the
level of the audio going through the device, providing gain increase as well as attenuation.

function is engaged, the Control Room output signal is attenuated by 20 dB.
