The Clear-Com PS-704 is a single rack space, one- to four-channel intercom system power supply which can provide up to 1.2 amps per channel to operate Clear-Com beltpacks and remote stations. This power is supplied to any or all of four channels and will support up to 40 beltpacks or 10 speaker stations.
Clear-Com's fail-safe design automatically shuts down the power to a channel when a short circuit or electronic overload is sensed on that channel. The other channels continue to operate normally. Once the fault condition is removed, the PS-704's fail-safe circuit will bring the power back up, even under full load conditions. LED indicators signal a fault on any channel. A line-level program input offers a master input level. Individual program selects, each with its own send level, are provided for each channel. Use of a switching power supply allows the PS-704 to operate with any AC line voltage from 100 volts to 240 volts AC at 50 Hz or 60 Hz. The metal chassis and extra-thick front panel with integral rack ears maintains legendary Clear-Com ruggedness.
In addition to providing system operating power, the PS-704 offers four channels of intercom with switchable line terminations for each channel. Two parallel XLR connectors per channel are provided. The power supply connects to remote stations with standard 2- conductor shielded mic cable. The PS-704 accepts a line-level program input signal, with a global input-level control. Front-panel-mounted program on/off switches and level controls for each channel allow the user to feed program audio to any or all of the intercom channels.
