Product Description
Pro Intercom MS300 3-Circuit Wired Intercom Master Station
Overview
The MSM301 is an accessory to the MS301. When connected by its single cable, it adds 3 more circuits, for a total of 6, to the MS301. The new circuits have all the functions of the original three, and are operated in the same manner. The MSM301 is powered by the MS301 and so does not add extra power to the system. It does allow the operator to communicate independently with three more circuits. Because each circuit of the MS301 and the MSM301 are capable of being either intercom or IFB channels, the need for a whole separate IFB system may be eliminated. The MSM301 occupies one rack space.
Features
- Three circuits
- Each circuit can be intercom or IFB in any combination
- Circuits are linkable (A + B) or (A + B + C) with auto termination impedance adjustment
- Each circuit's termination can be lifted via rear panel DIP switches
- Independent level control of program audio output for each circuit with an LED VU meter for each
- Mic switch on each circuit can be tapped for locking or held and released for momentary
- Internal power supply is linear (except for microprocessor functions) with 2.4A continuous output
- Toroidal transformer with extensive monitoring and auto-control of overload and heat considerations
- Full duplex, hands-free operation, in moderately noisy environments. (with optional gooseneck mic.)
- Paging output (balanced and isolated) on rear panel activated by front panel momentary button
- Dry contacts on rear panel also closed by page button
- Front panel 4-pin XLR may be used for gooseneck mic. or headset
- Gooseneck or headset mic. may be dynamic or electret. Lighted front panel switch sets choice
