Inter-M DPA-300Q

The Inter-M DPA-300Q is a Quad channel (4 x 300W) 100v Line Class D Power Amplifier for professional, zoned PA, AV and background music installations and rack builds.

Housed in a discreet and compact 2U casing, this 4 x 300 Watt, 100v line, four-channel Power Amplifier offers both size and weight reduction benefits.
The DPA-300Q 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 centers, school, colleges, airports, warehouses, etc.).
 
Featuring 4 x 300W individual channels, the DPA-300Q is ideal for multi-zone applications (such as ‘reception / restaurant / gym / bar’ or ‘classrooms / hall / café /admin’), where the same signal may be required at different output levels. Alternatively, the 4 channels can be used as separate amplifiers, sending completely different signals to each of the four zones / areas – ideal for use in conjunction with the Inter-M PX-8000 Audio Matrix.

The 4 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.
