About the miniDSP AMP-8

The AMP-8 is miniDSP’s 8-channel power amplifier, built around ICEpower Class D modules for a high power-to-size ratio in a compact 2U rack-mountable chassis. It’s designed to complement the Tide16 processor, but the AMP-8 works just as well with any processor, preamp or active crossover with balanced XLR outputs.

Each of the eight channels runs from a shared 1500W ICEpower switch-mode supply, delivering 300W per channel into 4 ohms or 150W into 8 ohms, with 2400W of peak headroom on tap. A 123dB signal-to-noise ratio and 0.0008% THD+N keep the amplifier’s own contribution to the sound close to zero, whether it’s driving a multiway active speaker system, a whole-home multizone install, or the full complement of channels behind a home theatre processor.

Features

Amplification

IcePower Class D amplifier modules

Four IcePower 300A2 modules, driven by a dedicated 1500W IcePower switch-mode supply.

300W per channel at 4 ohms

150W per channel at 8 ohms, with 2400W of peak power on tap from the supply.

123dB signal-to-noise ratio

Low distortion (0.0008% THD+N at 10W) keeps the amplifier out of the way of the source.

Connectivity & control

Eight balanced XLR inputs

38kΩ impedance and 2V RMS sensitivity, ready for a processor, preamp or active crossover.

12V trigger in/out

Powers the AMP-8 up and down automatically alongside the rest of a system, with the trigger output able to daisy-chain to further amplifiers.

USB firmware updates

Keeps the amplifier current without opening the case.

Build

Compact 2U rack form factor

A high power-to-size ratio for multizone or home theatre racks with limited space.

Removable feet and rack ears

Mounts in a rack or sits freestanding on a shelf.
