Product Description

The DPA1200S is a 1200W, 100v Line Class D Power Amplifier for professional PA, AV and background music installations and rackbuilds - the highest power version of InterM’s DPA compact power amplifier range.

Housed in a discreet and compact 2U casing, this 1200 Watt 100v line, single-channel Power Amplifier offers both size and weight reduction benefits.

The DPA-1200S features Class-D amplification circuitry and a switch mode power supply to provide significant efficiency improvements (typically up to 90% efficient compared to an average of 40% efficiency in conventional amplification).

This compact, high power professional power amplifier is ideal for large scale PA systems where high power is required over a long speaker line (such as shopping malls, supermarkets, school, colleges, airports, warehouses, etc).

The Class-D DPA1200S amplifier offers power efficiency in excess of 90% and ensures low power consumption and significantly reduced heat dissipation. Fully equipped with protection circuitry against short circuit, overload, power and DC output; Inter-M’s DPA Series amplifiers offer less than 1% THD, an increased signal to noise ratio of 90dB and a wider frequency response from 19Hz ~ 18KHz.

The DPA-1200S also provides Dual Input capabilities, allowing a priority input signal to override the standard/normal input signal; an ideal feature to support emergency paging systems.

The DPA Class-D Amplifier range is available in 1, 2, 3 and 4 channel versions, with power output options of 300W, 600W, 900W and 1200W per channel.

With reduced space capacity requirements, lower heat dissipation and significantly reduced power consumption, the InterM DPA 100v Power Amplifier range will now be specified into many of CIE’s in-house designed and built PA / BGM racks.
