Yes Bimmer, it's a stereo unit. Since I was building a dual-mono amp, I was worried about the share of this component by the two channels. The cross-channel talk due to this component is negligible.
A.Wayne, my Hx amp has a power-on thump. It also has a power-off delay due to the DC voltage that depletes progressively as the caps discharge. When the speakers are directly connected to the boards, I can have music for as long as 30 seconds after disconnecting the unit, just because of the voltage reservoirs, or just a few seconds when it's playing louder...
Many high-ends or high-power power-amps have this kind of circuitry, either with electro-mechanical components (relays) or by other solid-state means.
This circuit may have saved my speakers already, I explain: I was connecting / disconnecting my speakers while music was playing (rather loud), and guess what? I briefly shorted the amp output without noticing. It blew only ONE of the on-board fuses, thus only throwing the negative portion of the sine-wave to the speaker. This protection crcuit instantly disconnected both speaker outputs, preventing any damage to the speakers themselves. After replacing the blown fuse, everything was back to normal.
Nota: I don't make any money by suggesting this (hahaha)

My DX Blame does the same thing. A power-on thump, and a "burp" after a long delay after power-off. Maybe I should get me one of those protection circuits too.
What do you all think of these Speaker Protection Modules?
Because I have mono-blocks this seems to me a good solution.

My understanding such devices hurt sonics , no..? if so I prefer smoke to bad sonics ....
