Delta 40

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 40 yields a more-than-ample 4x 1000W of power at 4 ohms – or 2x 2400W when bridged. And it does so without breaking a sweat, while delivering enviably low distortion and noise figures. For instance, THD is as little as <0.18% at 1kHz. 

Analogue or AoIP via Dante? Delta 40 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.

You also get back-up amplifier redundancy, ensuring that your production can move ahead almost regardless of what might happen on the amp side of your studio.

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.
