Connectivity

Other Connectors

MOH 1V Line Output RCA Connectors: Two RCA connectors (mono) for 1-volt output (in parallel with 600-ohm connectors, so they are isolated).

MOH 1W Line Output Connector: 3-pin Phoenix connector provides Music-On-Hold signal of approximately 1 watt.

MOH 1V Line Output Phoenix Connector: 3-pin Phoenix connector, 600-ohm transformer-isolated output, provides Music-On-Hold signal of approximately 1 volt.

Amplifi er Output Connectors: 4-position terminal strip with COM (Common), 4 ohms, 25V and 70V terminals. Accepts up to 10 AWG crimp-on terminal forks. Non-touch cover included.

XM Radio Stereo Line Out Connector: Dual RCA jacks for stereo music out from XM Radio tuner. Preamp Line Out Connector: 3-pin balanced Phoenix-type connector. Post master, pre-VCA. Level controlled by master volume control.

Output VCA Connector: 3-pin Phoenix-type connector for two VCA control lines of +10 VDC and ground. Compatible with Crown 1-VCAP module.

Priority Connector: 3-pin Phoenix-type connector for push-to-talk mic switch. Contact closure activatges ducking. Ducking does not affect Music-On-Hold outputs or XM stereo line out.

Mic/Line Input Connector (Input 1 only): 3-pin Phoenix-type, balanced.

Line Input Connectors (Inputs 2 and 3 only): 3-pin Phoenix-type, balanced.

Dual RCA Input Connector: For stereo music signals, unbalanced, summed together, two connectors per input for inputs 1, 2 and 3.

TEL Input Connector: Transformer-isolated 600-ohm input, summed into Input 1 for paging from a telephone system.

Amp Input Connector: 3-pin Phoenix-type, highimpedance balanced. Used to link an additional mixer to the mixer-amplifi er. Can be used to connect an external processor.
