Question on BB2125 2 Channel Amp

I just recieved the amp from a friend who indicated it wasn't working. When I power up, the red led indicator light, indicating "protected" lights up but I do not get the green led "active" to light up.

On this pwr up, I didn't have an active input source connected to it, will it only switch to active when it senses an input source connected?

Hi jgoudie

It is a signal sensing turn on unit, so will not turn on until you have supplied signal to it. Plug it into a signal source and see what it does. But unfortunately, in my experience the protection light coming on means there is a fault in the amp.

You can download the user manual for the amp from here. Click downloads in the middle of the page:)

I noticed it was 2 red lights inside the amplifier, what does it mean?


The amp has 7 LED's in total 4 whiteLED's provide back lighting
the bi-colour LED white/ amber is the power/standby indicator (amber when amp is in standby mode)
The two red LED's are on the Phono Board and form part of the phono amplification circuit.( D1 & D2)They are NOT fault indicators and should be lit during normal operation.

My amps stays in the clip mode where as the light on the two channel stays red


http://www.retrevo.com/support/QSC-RMX-4050HD-Amps-manual/id/23107ci658/t/2/

Page 7...

CLIP: red, to the left of each Gain control.

Normal indication: illuminates whenever the amplifier is driven beyond full power. The LED's brightness indicates the amount of distortion. Distortion that causes only brief flashing may not be audible.

During muting, the indicator fully illuminates. This occurs during normal "On-Off" muting.

Abnormal indication:

•Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.

•If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is adequate.

•A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.

•If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.

Amplifer Not Operating


The red led is the protect indicator.

When this stays red you have either a bad speaker or the amp has a blown channel. Those are the 2 most common problems with the protect light staying red.

Disconnect the speakers and if the amp turns on without speakers, you most likely have a bad speaker. Take them in to a service center and have them checked.

if you disconnect the speakers and it still stays red, you most likely have a bad channel in the amp.

There is nothing you can do with that except to take it in to be serviced.

Both of the possibilities are common problems with all car amplifiers.

Since you checked the wiring, there is really no other end user actions that can help you on this.

Sorry for the bad news, but if this information was of value to you a good rating would be appreciated and appropriate.

Let me know if you require any further help, I have been repairing car and home amplifiers for over 17 years and can help you on most questions

Stop putting out sound to subs


Ok This is a two channel High Current amp. It is stable to one ohm. If the Subs are single voice coil at two ohms the they have to be wired in Parallel that means (Red +) (Black -) are connected to the + and - of another sub and then the (RED +) (Black -) from both go to one output channel of the amp. You pair the other two in the same fashion on the other output channel. If you are getting no output (sound) at all first check if the amplifier is going into protect. (Usually indicated by a red led on the unit. If it is connect only one Sub to each output and see if the protect LED goes out. If it does then you should have sound at the subs. If not check that you have the sub output enabled on the HU some head units do not come with the sub output enabled on the HU. If every thig is enabled, with only one sub connected to each output and the protect LED is not on then your amp is probably blown and needs repair. Nice thing is that MA has a great warrenty policy. Check and make sure the protect LED is off. If it is on you probably have the SUBS wired wrong
