The new Inter-M DPA-900S is a Single channel (1 x 900W) 100v Line Class D Power Amplifier for professional PA, VA and background music.The DPA series is a high quality commercial amplifier that can reproduce crisp, detailed sound without noise with high S/N of over 100dB and low THD of less than 0.1%. Therefore, it is very suitable for BGM playback.
The Inter-M DPA-900S is a 900W, 100v Line Class D Power Amplifier for professional PA, AV and background music installations and rackbuilds.
Housed in a discreet and compact 2U casing, this 900 Watt 100v line, single-channel Power Amplifier offers both size and weight reduction benefits.
The DPA-900S 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, school, colleges, airports, warehouses, etc).
The Class D DPA-900S 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-900S 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.
High Performance Class-D Power PA Amplifier
High performance Class-D Power amplifiers produce 900Watt rated power each channel.
Emergency Power Back Up (24VDC) Capability
The unit operates on a DC24 V battery power supply for emergency back up without UPS (DPA-SO models are not included
with emergency power back Up (24VDC))Rated Output Power Via DC Backup Supply
Output power can be maintained as AC power when 24VDC power supplied.
Advanced Power Circuitry Design
The combination Class-D type amplification circuitry combined with SMPS creates a high efficiency amplifier offering reduced
power consumption and low heat dissipation and weight.High Quality Sound Design
The total harmonic distortion is reduced to less than 0.03% THD, with a high signal to noise S /N ratio of over 103dB
Advanced Protection Circuitry
Advanced protection circuitry guards against overheating, shorted outputs, DC output, overloads and mismatched power
A Variety of operation Indicators
Signal, -10dB signal level, Clip, Protection and system power (AC, DC, STBY) indicator
Balanced Input
This connection is used to ensure the lowest noise operation which eliminates the common noise from the cable.
Remote Power ON/OFF
he remote power allows the amplifier to be turned on or off from a distance or other device via dry contact closure.
PRIORITY Input
PGM is interrupted and over ridden by the Priority input, when a contact closure is received on the PRI select terminal. This is
Ideal for Emergency message broadcasting applications.| Specifications | DPA-900S |
