New - miniDSP AMP8, 8 channel Class D Audio Amplifier

[diablo]

I got an email from MiniDSP today which announced this new eight channel amp. Looks pretty good to me.

AMP-8

The miniDSP AMP-8 is an 8-channel power amplifier designed for home theater, immersive audio, and multizone setups. It stands out due to its remarkable power-to-size ratio and high efficiency. Utilizing ICEpower® amplifier modules, the AMP-8 delivers 300 Watts per channel at 4 ohms and 200 Watts...

If I were setting up my cinema system again I'd probably use one.

There's no DSP on board, so this competes with all these:

ICEpower 300A2s are nice modules, the first ones that came close to competing with Hypex.

Sounds like 4x 300A2s with a 1500S power supply, unfortunately this means power output will be limited by the power supply. Also, disappointing that they do not have an easy way of bridging a module without opening the chassis, there is a BTLselect pin that needs to be pulled high to synchronize the channels.

IMO, 8 channel amplifiers have too many drawbacks and the space savings are not worth it over multiple 2-4 channel amplifiers.

is this an issue in practice? is there content where all channels are driven even close to equally?

Probably not. Worse case application would be multiple subs. In an active setup, the mid/tweeter channels usually require much less power than sub/woofer channels.

It would be interesting to push 4 of the channels to clipping using a low frequency (say 40 Hz) and see what happens on other channels playing higher frequencies at lower power. Do the higher frequency channels end up with elevated distortion?

I agree with the last post. I don’t think that there will be power for 2400 W

Too bad its not 8 ohms too

scratch that, saw the pdf on the website, runs 8 too.

Inquired if the unit has a fan: “There is a single fan located on the side close to the amplifier modules; you can position the HTx on top of the AMP-8, as the footprint of the AMP-8 exceeds that of the HTx.”
