PRELIMINAR

Adjusting the input audio level

The audio level of each input can be adjusted from -18 to +24 dB. The factory

default level is 0 dB.
There is only one audio settting which is applied to both the left and right audio

inputs of the selected input device.
Audio level settings are stored in non-volatile memory, and retained through a

power cycle.
When performing the procedure below, you may monitor the Input Audio/Gain

Attenuation level via RS-232 using HyperTerminal (see chapter 4).
To enter the audio adjust mode and adjust an input audio level:

. Press and hold the Mute button for 2 seconds. The I/O Audio LED and one of

the input LEDs (ex: input 7) flashes indicating the audio adjust mode.

. Press the desired input button. The selected button’s LED begins flashing.

There is no indication of the audio level available by viewing the front
panel. You may monitor the volume level adjustments via an RS-232
connection and HyperTerminal (see chapter 4).

Pressing an input button while in audio adjust mode will
activate / de-activate a tie.

. Turn the Volume control knob clockwise to increase volume and

counterclockwise to decrease the volume level of the selected input.

. Press and release the I/O button or wait 30 seconds for the unit to exit the

audio adjustment mode.

Pressing the Mute button while in audio adjust mode will activate the
mute for output 1.

Audio outputs

Balanced or unbalanced audio output is available on the MPX 423 A using a 3.5

mm, 5-pole captive screw connector, wired as shown below.
