The Cornered Audio CA280DSP two-channel power amplifier, designed for high-performance multi-room audio installations, is now available from Karma-AV.

The compact CA280DSP delivers up to 2 x 140W or 1x280W in bridge mode. It can also deliver 280W in 70V/100V mode, or run one channel in 4/8 ohm while the other channel runs in 70V/100V mode.

The fan-less amplifier includes two Class D output stages boasting ultra-low distortion, and a full set of circuit protections.

The CA280 also offers integrators powerful room correction tools when used with Cornered Audio PC software and free-to-download Audio Stream Input/Output (ASIO) software controlled via Ethernet, USB or Wi-Fi.

Running 48 kHz/24 bit and high performance 24bit AD/DA converters, the DSP provides installers with a range of loudspeaker processing options. Each band can be switched to Bell or Lo/Hi-Shelving with variable Q. The HP/LP filters offer slopes from 6dB/octave up to 24dB/octave including Butterworth, Bessel and Linkwitz-Riley crossovers.

For Auto EQ, the amp’s DSP software works with any third-party AISO virtual soundcard and external mic to run local EQ sweeps for room response optimisation down to 25Hz. This works for all connected speaker systems, but complete Cornered Audio amp/speaker setups can be optimised via the amp’s built-in response presets.

Phoenix line-level inputs connect any balanced or unbalanced signal from the preamp. Multiple CA280s located centrally or locally can be daisy-chained together via Phoenix link outputs; the software supports up to 32 amps simultaneously.
