miniDSP AMP-8

8-channel amplifier

The miniDSP AMP-8 is an 8-channel Class D power amplifier, designed for immersive home theatre systems, multi-zone setups and demanding audio installations. Based on ICEpower modules, it combines significant power and a compact 2U rack-mountable format.

ICEpower architecture

The AMP-8 combines four ICEpower 300A2 amplifier modules and one ICEpower 1500S power supply module. Each channel delivers 300 W RMS into 4 Ω and 150 W RMS into 8 Ω, from 20 Hz to 20 kHz. The universal switch-mode power supply provides 1,500 W continuous and up to 2,400 W peak: enough to drive all eight channels at once in a home theatre or across several listening zones. A set of protection features is built in.

High-level performance

The signal-to-noise ratio reaches 123 dB(A) and the frequency response stays flat within ± 0.5 dB from 20 Hz to 20 kHz. THD+N is 0.0008% at 10 W (4 Ω, 100 Hz). A quiet, neutral amplifier that steps aside behind the processor and the speakers.

Integration

The eight balanced XLR inputs (38 kΩ impedance, 2 V RMS sensitivity) connect directly to a multichannel processor. Paired with a room correction processor such as the miniDSP Flex, or with a home theatre processor, the AMP-8 forms a complete chain for a multichannel system. The 12 V trigger input and output let the amplifier switch on and off with the rest of the system. The USB port is used for firmware updates.

Ideal for integrators and enthusiasts who want to drive a multi-channel or multi-zone system with professional power and reliability.
