AMP H Series — Audiophony PA 100 V line amplifiers

One power rating. One zone count. Always the same compact format.

Discover the AMP H amplifier range, built for 70 V and 100 V constant-voltage line installations. From 150 W to 500 W per channel, 1 to 8 zones depending on the model, always in the same compact 1U 19″ rack format.

Match your power

Choose the power. The wiring does not change.

Power is rated per channel, on 70 V as on 100 V. On the four-channel models it is given with two channels active; with all four channels loaded, each output delivers 135, 270 or 400 W.

Sound quality

Clean sound, from the amplifier to the end of the line.

The Audiophony PA AMP H range puts the sound quality of your installation first. Every amplifier is designed to deliver a clean, natural signal, with no colouration and no audible distortion — for voice paging, background music or all-day continuous playback alike. The result: clear, controlled sound, from the first metre of line to the last loudspeaker, whatever the size of the installation.

That quality rests on measurable figures: THD+N below 0.1 % and a signal-to-noise ratio above 95 dB keep the sound clean even at full output, while a damping factor above 200 gives tight control over the driver, for a well-defined result — including at the far end of a 100 V line.

Connections

All connections at the rear. Protected.

Inputs and outputs on pluggable Euroblock terminals, line selection by switch, and on the four-channel models a second output terminal per channel to daisy-chain a second speaker line without splicing.

Cabling

How far does the line go?

Maximum length of a 100 V line depending on amplifier power and cable cross-section, without degrading the signal. Never use shielded cable to carry the power signal.

PowerMin. impedance1.5 mm²2.5 mm²
150 W67 Ω800 m1,300 m
300 W33.5 Ω400 m700 m
500 W20 Ω180 m350 m

The total power of the speakers connected to an output must not exceed the amplifier's power.

Optional on the 4-channel models

Dante, when the network replaces the cable.

The AMP-DANTE4 card fits inside the AMP150.4H, 300.4H and 500.4H. The four channels then receive their sources over the installation network, with no audio line to run to the rack. Routing is handled in Dante Controller.

Applications

One range, many kinds of site.

The same amplifier, the same wiring, very different sites: the choice comes down to the number of zones and the power required on each line.
