MUSYSICProfessional 4-Channel Amplifier – 2x9600 Watts D-Class 1U Power Amp MU-D9600 High Performance Amplifier with Stereo & Bridge Power for Professional Use in Concerts & Functions and at Home

Took a chance on the Musysic MU-D9600. I bridged it to 2 channel, to drive my bass bins. My impedance on both channels are at 4 ohms. I was pleasantly surprised how easily this thin amplifier pushed my 5000 watts speakers. Now. Even though the manufacturer professed 2x9600, it will not give that. I suspect more like 2x3000 peak, which is still not bad at this price. Time will tell with little amp, so far so good.

I'm using this 4 channel amplifier to drive passive monitor speakers. The value pricing made it a winner. If a volume knob is advanced past the 9 o'clock angle, then a whine from the switching power supply becomes obvious. So I keep each volume knob just below this point. The mixing console is able to send enough signal through this amplifier for acceptable monitor usage.

Normally I use a Crown XTi 6002 for Bass, I changed it to this Amp and the results are awesome. Presently I'm waiting for it to be back in stock so I can order two more.

Would have given 5 stars if they advertised the actual realistic wattage. 9600w is a joke. It’s the peak wattage at 2ohms if you combine the value of all channels in bridge mode which is basically a regular 2-channel amp (which doesn’t make sense in real world usage). Why would anyone use a 4-channel amp in double bridge mode? That’s what regular 2-channel amps are for.If you’re using four 8ohm speakers, they’re each getting 300w rms. That’s a realistic spec. Ignore the peak values. That’s just marketing hype. They really don’t mean anything when you have all your gear setup and playing music.The amp sounds fine. I have a unique setup. I use pioneer s-fl1 flat panel speakers paired with EV SB122 12” subs. I also have Peavey PR12 speakers. I tested the amp with different speaker/sub setups for about four hours. Everything sounds fine.Each knob has a different stiffness. Channel B gets really hard to turn at the 2oclock position. Quite annoying but I can live with it.

Let see

The switch no working.

One of the value knob not making contact

Don't worry about hearing damage with these amps, not saying it's impossible but highly unlikely. Need I say more...
