Sonance Pro Series 70 V SONAMP DSP 2-750 MKIII Amplifier

Product Overview

The Sonance SONAMP DSP 2-750 MKIII is a two-channel 70V commercial DSP amplifier built to drive distributed audio across large commercial installations. Its onboard digital signal processing handles equalization, crossover, and delay so integrators can tune each zone from a single 2U rack-mount chassis. With 750 watts per channel at 70V, it supports long speaker runs and high device counts typical of 70V/100V constant-voltage systems. It is a direct fit for conference rooms, training rooms, and multi-zone background music applications.

Product Description

The SONAMP DSP 2-750 MKIII is a rack-mount commercial audio amplifier designed for AV integrators specifying distributed sound in commercial spaces. Each of its two channels delivers 750 watts at 70V or 4 ohms, with 500 watts per channel at 8 ohms and 2,000 watts peak when bridged at 8 ohms. The built-in DSP gives system designers parametric equalization, configurable crossovers, and time delay, allowing one amplifier to serve multiple acoustically distinct zones. A 5Hz–50kHz bandwidth-limited frequency response keeps full-range program material clean across paging, background music, and presentation audio.

The 2U chassis occupies minimal rack space and ships with both rack ears and feet, supporting either equipment-rack or shelf placement in an AV closet. Dual-voltage operation (100–120V and 220–240V) makes it suitable for North American and international commercial deployments. As a 70V DSP amplifier for distributed audio, it pairs naturally with Sonance Professional Series in-ceiling, pendant, and surface-mount loudspeakers configured on a constant-voltage line. For integrators standardizing on a single platform, it consolidates amplification and signal processing into one serviceable unit.

Technical Specifications

Frequently Asked Questions

What loudspeakers is the DSP 2-750 MKIII compatible with?
It drives 70V constant-voltage loudspeaker lines as well as 8-ohm and 4-ohm loads, making it compatible with Sonance Professional Series in-ceiling, pendant, and surface-mount loudspeakers wired for 70V distribution.

How much rack space does it require?
The amplifier is a 2U component and ships with rack ears for standard 19-inch equipment racks, plus feet for shelf placement.

Does it require external signal processing?
No. Onboard DSP provides equalization, crossover, and delay per channel, so most installations do not need a separate processor for zone tuning.

Can it be used in international installations?
Yes. The power supply supports 100–120V at 60Hz and 220–240V at 50Hz for North American and international commercial deployments.

What warranty and support are available?
This amplifier is covered by the Sonance manufacturer warranty. Creation Networks provides pre-sale system design support and post-sale assistance for commercial AV buyers.
