(lowest)

The boom/gooseneck mic has priority over the desk mic when no headset is connected. Desk mic audio and PTTs are ignored if a headset or boom/gooseneck mic is connected.

Boom/Gooseneck Mic (if used)

A boom microphone (option CRMC3E or equivalent) or a gooseneck microphone (option CRMC3F or equivalent) may be connected to the Enhanced Audio Enclosure as follows:G￿

Mount the microphone in accordance with the instructions supplied with the mic. With the gooseneck microphone, the supplied male DB-9 connector must be soldered to the cable's wires in accordance with Table 6 after the mic's cable is routed through the mounting surface. Connect the boom/gooseneck male DB-9 connector to the female DB-9 connector labeled "B/G MIC" on Enhanced Audio Enclosure's rear panel. Cable length is four (4) feet (1.22 meters). Table 14 indicates the "B/G MIC" connector's pin-out.

CAUTION!

DO NOT connect a boom or gooseneck microphone to one of the other female DB-9 microphone connectors at the rear panel of the Enhanced Audio Enclosure. Damage to the boom/gooseneck mic's magnetic voice coil may occur.

NOTE

All boom and gooseneck mic connectors (male DB-

9)must have pins 2 and 3 jumpered together so the sense circuit will be active when the mic is connected to the Enhanced Audio Enclosure.

Footswitches (if used)

Two (2) female DB-9 connectors are located on the rear panel of the Enhanced Audio Enclosure for footswitch interconnections. Footswitches used with the C3 Maestro dispatch console include single-footswitch option CRSU3B and dual-footswitch option CRSU3C. On the dual- footswitch, one switch (PTT) keys the mic and the other switch is a monitor switch. A single-footswitch provides only a PTT function. See Tables 20 and 21 for specific connector pin-out details. Footswitch operation is as follows:

∙Depressing the PTT switch on a footswitch connected to the "OPER FT. SW." DB-9 connector will activate the operator's headset mic if the headset is connected. If the headset is not connected, the boom or gooseneck mic will become active when this footswitch PTT switch is depressed.

∙Depressing the PTT switch on a footswitch connected to the "SUPER FT. SW." DB-9 connector will activate the supervisor's headset mic if the headset is connected.

∙If a dual footswitch is connected to either the "OPER FT. SW." or "SUPER FT. SW." DB-9 connectors, depressing its monitor switch will activate the console's conventional channel monitor

G￿function.

All footswitch cables terminate with male DB-9 connectors. Mate the appropriate male DB-9 footswitch connector to the respective female DB-9 connector at the Enhanced Audio Enclosure's rear panel. Tables 20 and 21 indicate "OPER FT. SW." and "SUPER FT. SW." connector pin-outs.

Speakers (if used)

Desktop and rack-mount Speaker Assemblies used with the Enhanced Audio Enclosure each basically consist of mechanical hardware, one or more speakers, audio amplification circuitry, and a volume control potentiometer. The mechanical hardware may be of several different varieties providing either desktop speaker operation in the form of a self-contained single-speaker case or a rack-mount version in the form of a standard 19-inch EIA rack mount assembly. The 2-speaker rack-mount versions are generally
