Crest Audio CPX-900 Amp


The right speaker (Community MVP15HO's) is not as loud and clear as the left speaker. Both left and right volume controls are at the same setting and both green light indicators are on. The sound quality is slightly off and not as loud as the normal speaker. I've tried switching cables, but it stays the same which tells me the cables are ok.

Crest audio cpx 1500 , one channel stop working ,

The breaker is stuck because there's some internal circuit problem on the amp. Something is tripping it i.e. a wiring short or blown speaker driver if they're connected, or an output transistor has blown.

Fix the problem BEFORE trying to reset.

Switch all off. Disconnect your speakers from the power amp. Switch the amp back on. If it will reset now then you have a wiring or speaker issue. If it won't reset then the problem is something broke in the amp.

Transistors are part of the circuit board. They're soldered in and also bolted to heat sinks. Not a DIY fix unless you know what you're doing. Take the amp to a repair shop.

I have a Crest Audio V900, a set of Bose 901, a Gemini EQ-3000. Do I need a PREAMP? Or can I hook up the Crest AMP to the Equalizer?

You could use the EQ but it won;t sound as good as it will with a pre amp and also could make it a bit trickier when adjusting the volume and getting it to sound right.

I have a pair of JM lab Electra 905 speakers, running through a DNM amp and power amps. When powered up, the left speaker makes a very loud humming noise. This has happened recently. I haven't changed...

Switch on your amp, keep its volue down to extreme low, and listen if there is still hum through the left channel or not. If still there is hum, the left side power amplifier section inside the amp;ifier is faulty. If htere is no hum at this state, hum enters thorugh the audio input terminal, and the input wires must be checked for open sheild connection. OK.

I have a crest 901 and the banana plgs will not insert into the amp. I bought it from a guy on ebay and paid for shipping and insurance. i am afraid that aaaaI got messed over. the amp was not insured, but...

Find a local music store that sells power amps and see if they know a tech who can look at it. If the banana jacks are whacked , theyre easy to replace

Can cpx 900 be bridge @4 ohm?

The short answer is no. This amp was designed to be bridged with an 8Ohm load not 4. That being said, the unit will work, but get very hot and possibly get damaged should you provide it too low an impedence load. DO NOT conenct this ti a 4Ohm load in bridge mode.

Every time I turn the amp on it shuts its self off.

disconnect all speakers and test if the problem corrected you will have a problem in your speakers(either wire or speaker itself)-try to connect the speakers one by one until you find the bad one and change it--if all above does not work send your amp to service center near you

What Crest Amplifier series replaces the VS series

This is kind of an ambiuous question. Are you looking for barrier strip inputs and outputs? Are you looking for 70V output lines? Or are you looking for a standard 1/4" TRS input with either 1/4" or speakon outputs? If you can describe your application requirements, I can provide you with a recommendation.

No power

These amps are very compact and are not the easiest to work on. If you are not experienced at repair, I would not recommend you start here. Where are you located?
