Not long ago, we looked at the impressive new DM-810 digital signal processor from AudioControl. In keeping with their plan to provide consumers with access to the benefits of signal processing, AudioControl has recently introduced the D-4.800 amplifier. The D-4.800 is a high-power four channel amplifier with a built-in, six-channel DSP solution. You get the best of both worlds in one small, yet powerful package!
Prodigious Power Production and Input Features
The D-4.800 will produce 125 watts per channel at 4 ohms and 200 watts per channel when presented with a 2-ohm load. Each pair of channels can be bridged to provide 400 watts into a single 4-ohm load. The amplifier will accept preamp input signals from 250 mV up to 8 volts per channel on its four RCA jacks. Unique to a four channel amp, AudioControl has provided three pairs of speaker level input plugs. The rear speaker level inputs are in stereo, while the front channels provide high- and low-frequency inputs to sum midrange and tweeter signals. Each pair of channels has an input sensitivity control and stereo signal delay adjustment within the DM Smart DSP application. The software also provides an MILC input signal clipping indicator, so you know if you are overdriving the input stage of the amp. The speaker level inputs will accept up to 40 Volts of signal. AudioControl kindly included their GTO (Great Turn On) circuit to turn on the amp when a factory source unit or amplifier is switched on.
