Intercom with amplifier mode

The MLC’s Audio Out 2-pole captive screw connector outputs

a -10 dBV audio signal that can be routed to an MPA 122 or any

external audio amplier, then to speakers.

1. Cable the system as shown in the following diagram.

2. Power on the equipment.

3. Make ne adjustments to output level using the Remote

Line slider in the Advanced Settings part of the HelpDesk

software. The external amplier (the MPA 122 in this

example) must be adjusted properly to avoid any audio

signal clipping or audio distortion.

4. If desired, use the software to adjust to minimum levels the

MLC’s audio output, the IPI’s speaker output, or both.
