Description



Dynaudio Acoustics Delta 80 DSP

Maximum power, sophisticated DSP and remote control. A total rack-star…

Every model uses the highest-quality power-amplifier technology – so you know for a fact that what goes in, comes out exactly as intended. Only louder.

The 2U Delta 80 DSP yields a staggering 4x 2000W at 4 ohms – or 2x 4000W when bridged. And it does so without breaking a sweat, while delivering low distortion and noise figures. For instance, THD is as little as <0.18% at 1kHz.

Analogue or AoIP via Dante? Delta 80 DSP handles up to four channels; it’s a future-proof system that can keep up with whatever your studio throws at it. When using Dante, your audio is converted by 24-bit/96kHz DACs.

And should the need for room tuning arise, you also get access to sophisticated DSP features. These span three dynamic and eight static EQ bands per input channel, and nine static EQ bands per output. Plus a suite of additional filters.

You also get wireless control via the DeltaDirect app for iPad, GPIO for remote control and monitoring and redundant back-up amp inputs. 

Want a stereo four-way system? Just connect to a Delta DSP amplifier with a single Cat 5 cable to eliminate the need for external processing.
