Professional 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

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.

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.

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.

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.

I don’t give 5 stars ever so 4 will do. I have been doing a concert series with the two channel and 4 channel in a rack. Mains are JBL MRX 515 and monitors are a Frankensteined Rockville 12” cabinet. Though I have amps with bigger power these have preformed above my expectations. So far my artist have been Grammy nominees. I’ve know them for a few years and they are knowledgeable about good sound. They were happy. The only issue I have is the cooling fans failing. I changed my 2 channel out with a different brand name and they have worked great. There is a summer of work ahead so we shall see. Peace
