PHM-802C digital amplifier switchover unit is designed to monitor up to 10 power amplifiers simultaneaously. Up to 8 amplifiers can be configured as call amps, backed up by up to 2 spare amplifiers.
PHM-802C works self-sustaining and independent of other components. Alternatively, it can be integrated into a VARES-3000 system.

Features

• Setting up PHM-802C is done easily via a clearly represented menu that is desplayed on the big front display. All the programming work is done by just four function keys, a computer is not necessary to configure PHM-802C.
• The health status of each connected amplifier is shown on the front display.
• Faults will be indicated until the cause of the problem is repaired.
• All connectors are service-friendly pin-and-socket-connector types that are perfectly suited for installed audio equipment.
• 8 call amps can be linked with 1 spare amp, or two groups made of 4 call amps each can be linked to 2 spare amps (1 spare amp per group). Can also be used without spare amplifier.
• PHM-802 C offers an input for 230 V AC switching power supply (switched to 24V) and an additional input for 24 V DC emergency power.
• A bigger number of amplifiers can be monitored by using several PHM-802 C.
• The measured level of the pilot tone can be adjusted for each 100V power amplifier at the device.
• A variety of pilot tones is available, ranging from 19 kHz to 25 kHz.
• An alarm output for external fault messages allows easy routing of messages within the voice alarm system.
• The menu is available in English or German language.
• Optionally the monitor module PMU-802A can be installed to intercept all 10 amp outputs.
