Product Description

The Inter-M DPA300D is a Dual channel (2 x 300W) 100v Line Class D Power Amplifier for professional, zoned PA, AV and background music installations and rackbuilds.

Housed in a discreet and compact 2U casing, this 2 x 300 Watt, 100v line, dual-channel Power Amplifier offers both size and weight reduction benefits.

The DPA300D 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, 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, leisure centres, school, colleges, airports, warehouses, etc).

Featuring 2 x 300W channels, the DPA-300D is ideal for two-zone applications (such as ‘sales offices and warehouse’ or ‘retail floor and storage’), where the same signal may be required at different output levels. Alternatively, the 2 channels can be used as separate amplifiers, sending completely different signals to each of the two ‘zones’.

The 2 channel Class D 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.

Each channel 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 Inter-M DPA 100v Power Amplifier range will now be specified into many of CIE’s in-house designed and built PA / BGM racks.
