QUICK START EXAMPLES

OWNER'S MANUAL

Example 1 - System Paging, BGM, and MOH with Emergency Page Override

When a page signal is received from INPUT 2 and the RMT MUTE terminals are shorted, the page will be the only audio heard in the main system because BGM will be muted. If an emergency page comes into INPUT 1, all inputs will be muted except for the emergency page. Note: Zone 3 MOH output will not be muted or affected by either page scenario.

Connect a paging mic to INPUT 1. This will be the priority emergency page over ride mic input. Note: The INPUT 1 Trim and Sens will need to be adjusted after all the settings and connections have been set.

Connect a paging mic with a switch to INPUT 2.

Connect the switch wires from the mic connected to INPUT 2 to the "RMT MUTE" terminals. Note: The polarity on the switch to the terminals does not matter.

Set Dipswitch 9 and 10 to the "MIC" position.

Set INPUT 1 to Mute Send.

Set INPUT 2 to Mute RCV.

Connect a BGM player to INPUT 5. Note: The input gain of this channel may need to be changed for proper level balance. Dipswitch 6 allows you to select between a 100mV or 300mV input sensitivity.

Connect Zone 3 output to the MOH input on your telephone system. Adjust Input 5's Zone 3 output level as needed.
