Art MX624 [6/16] Front panel controls

OPERATION

Front Panel Controls

DUCK Switch

Pushing this switch in enables ducking in response to the signal from the MIC 1 input.

Pushing this switch again returns it to the out position and disables ducking. The switch

is illuminated by a red LED that is part of the ducking circuit, so it provides useful

feedback about the amount of ducking applied as well as indicating basic on/off status.

With ducking enabled, the LED is dimly lit at the onset of ducking with relatively low

level microphone signals. With higher level microphone signals, ducking becomes

more fully engaged and the LED becomes brighter. Note that the LED lights briefly

when power is first applied, even if there is no microphone signal or the switch is in the

out (disabled) position. This power-on ducking helps prevent unwanted noise.

CHANNEL Controls (1-6)

LEVEL

Each of these controls adjusts the level of the associated input channel and

determines its contribution to the overall mix. Unused inputs should have their

associated level control turned off (0 position or fully counterclockwise) to minimize

potential stray noise pickup.

Keep in mind that the best noise performance, while keeping distortion to a minimum,

is obtained with each control adjusted to the maximum desired level (towards 10. In

other words, in general, keep the CHANNEL LEVEL controls turned up and turn the

ZONE LEVEL controls down to compensate, rather than the opposite.
