Four zones, compact format.<\/strong>
The AMP150.4H targets multi-zone installations where each line only needs moderate power: small retail, offices, corridors, meeting rooms. Four independent channels each deliver up to 150 W on a 70 V or 100 V line, with an independent voltage selector per channel at the rear and a per-channel volume control on the front panel.<\/p>\n

Priority and supervision built in.<\/strong>
Beyond amplification, the AMP150.4H carries control logic designed for day-to-day operation: a priority TEST input, triggered by a dry contact on the PRI terminal, instantly switches an announcement across every zone. The FAIL (5 V fault output) and DIS (disable) contacts report the amplifier’s state to an external supervision system, useful wherever a failure has to be detected remotely.<\/p>\n

Measurable sound quality.<\/strong>
THD+N below 0.1 % keeps the signal faithful even at full output, with no audible colouration on speech or on music. A signal-to-noise ratio above 95 dB lets silence stay silent between two announcements. A damping factor above 200 keeps the driver under control for a well-defined result, including at the far end of a 100 V line.<\/p>\n

Ready for Dante.<\/strong>
The AMP150.4H accepts the optional AMP-DANTE4 card, which moves all four channels onto the Dante audio network through two redundant RJ45 ports. An analogue amplifier today, ready for a networked installation tomorrow, without replacing the hardware.<\/p>\n

Connections and integration.<\/strong>
One Euroblock connector on the input and two on the output of each channel (wired in parallel), in the same format as the rest of the AMP H Series. Short-circuit, open-circuit, thermal, limiter, ultrasonic and radio-frequency protection as standard. Variable-speed fan cooling, 62.5 dB at 1 m, AC 220 \u2013 240 V power supply.<\/p>\n

The AMP150.4H is part of the Audiophony PA AMP H Series, available with 1, 4 or 8 channels, from 150 to 500 W per channel.<\/p>\n
