NO SOUND OUT PUTPUT? RCA is plugged into output line to amp. AMP is fully functional. Other on related equipement use on the amp to test it, Gemini volumes are up. Channels have been moved from side to side. CDs player lights up and plays adn cues. Faders have been moved to check both cd players. Decibal meter shows no outputs signals..... The phono aux lines also had outside equipement tried through it on both line and phone out puts. No sound. RCA is red to red and white to white. In master and tried in recrd lines as well. NO SOUND OUT PUT? WHAT AM I DOIN WRONG or os things thing BROKE?

This is not a powered mixer and so you must connect a power amp to the "line level" outputs of the mixer. Other "no output" problems could be related to buss assignments and other signal routing issues. Check for output by connecting "Main Out" left or right to a guitar amp input instead BUT turn all volumes down to zero before conductiong this test as guitar amps are designed for "Microphone" level inputs. Owners and Hookup manuals can be found here...
Line level output of the mixer would go into the line level inputs of the EQ, and the EQ line level outpputs to the line level inputs of the amplifier. If you are faced with a mix of unbalanced inputs or outputs, to balanced inputs or outputs it gets a little complicated because you need to matrix the balanced signal to unbalanced load and vice versa. There is no single answer to doing this either.
RCA jacks are unbalanced, 2 conductor 1/4 inch connections are unbalanced most of the time. XLR and 3 conductor 1/4 inch jacks and plugs can be either balanced or unbalanced.If either are wired so left and right are a single ring or tip on the 3 conductor 1/4 inch jack, it is unbalanced and they would share a common ground lead. XLR wired with one pin common with shield and right and left have a single conductor on the plug or jack, that is unbalanced.
Could be power supply related- failing capacitors being most likely. Could also be PWM failure- Failing capacitors being the most likely. Output may have shorted out, or the MOSFETS or IGBT's may have failed.
typically (unless your useing other gear besides mixer and amp) you'd come out of the L/R outs. ( Main outs ) to the Main inputs of the power amp then out to your speakers (outs of power amp). Now the amp could be in bridge mono or other factors but typically, like i said, just Mixer Out- Amp In- Amp Out- Speakers.
You should NOT under any circumstances connect an audio input lead to a speaker output jack!
The RCA jacks you are trying to take output from ore "pre fader" which would be solid "line level" and not controlled by volume controls. Tap off the INPUT to the amp... you should be using balanced lines for the interconnects. RCA jacks are unbalanced lines. You can drive several inputs from a line level output of a mixer for example using a splitter cable.
A large amp like this likely has protection circuit (probably a relay) that doesn't connect the speakers until the amp is stable and balanced. You relly need the schematics for the amp.
Blown soeaker or amp. Only way to analyze is to open it aand do testing. First plug headphones into the 1/4 inch line output jack and see if anything comes through... it will only be in one ear as the ouptu is not a stereo output... If it comes to there, then the preamp and line driver is working, leaving the speaker and power amp suspect. If nothing ocmes out, I suspect the power SUPPLY might have failed.
You connect POWERED speakers to the left and right outputs... You MUST use POWERED speakers or an external amplifier. This unit has a small headphone amp, but that CANNOT power passive speakers.
The output section of this unit appears to have a problem. That channel is in protect mode and will not produce sound. At this point, you should return this for a warranty repair. While relatively rare, this can happen with new equipment. As long as you have not overdriven the amp, the warranty should take care of the problem.
There are two balanced outputs from the mixer as well as two RCA outputs (right & left). The simplest connection would be to run RCA cables from the RCA mixer output to the auxiliary input on an amp.
If you want to use the balanced outputs from the mixer, you will need adapters (or cables with correct plugs) to go from balanced conectors to RCA or 1/4 " inputs on the amp.
