4-Channel D Class Amplifier With DSP 4 x 76W

A592DSP Plug & Play DSP amplifier with Bluetooth audio streaming 4 x 76 W RMS

Our latest generation of DSP amplifiers convinces all along the line: with the A592DSP, not only has the range of functions been expanded to include a 31-band equalizer per channel, but the ability to stream music from your smartphone directly to the amplifier via Bluetooth audio has also been integrated. The new series relies on the proven ease of use with control via iOS and Android smartphones. Delay correction, freely configurable frequency filters (6/12/18/24 dB), gain control per channel, freely configurable parametric 31-band EQ and saving of settings on the cell phone – all DSP settings can be conveniently made via the cell phone app via Bluetooth. The second integrated Bluetooth interface makes it easy to stream your own music collection to the amplifier. Just pair your smartphone with the amplifier, press play – and you’re done. This plug & play DSP amplifier opens up previously unknown sound dimensions and offers outstanding performance. It is ideal for purist car hifi installations and offers a wide range of applications thanks to Plug & Play connection including Auto-Turn-On function and the integrated 5-channel DSP-controlled preamplifier outputs. The A592DSP is also 2 ohm stable, which extends the field of application even with various factory systems.
