Have this on my AV system for watching videos... love the hi density size with 75 watts of power output on tap. This set uses SVI2004A new class A power amplifier...

It may be an old matrix based surround, but it really is awesome when watching a favourite film... and it’s switchable, and variable (in the neat lil flip open panel)

It has another neat feature... computer EQ - this one has acoustic compensation - it will set the equaliser to deliver a flat sound - uses a mic (not supplied) will develop pink noise and adjust eq based on what mic hears.

It is compact and fan cooled, this model has a good feature- a thermistor on heatsink to prevent power IC getting too hot - thermal shut off - prevents blockslide.

In the systems I have, the direct connectors have the system functioning and very tidy... (not having to wire tape deck and tuner inputs.

The controls are well laid out, and the FL display is awesome!
