Hi I have a Yamaha DSP 3090 Amp my right main Chanel is not working Amp goes off when i try to put the power on i think it goes on protction mode?after trying for 5to10 times it comes on, test mode all chanels work well not sure whats wrong ? can anyone slove my problem
volume levels on all channels varies depending on what dsp mode you are using. to be able to determine the level you desire, just chnge the level setting of those channels. either you do it by remote control or the front panel of the amp. try setting the dsp mode on disco and you should hear higher vol levels on all channels. Do not expect as well all channels to produce same vol levels as your effects speakers may not be able handle higher power levels.
reverse your cable if the problem go to right speaker you have a problem in your amp and needs to fix-if the problem still in your left speaker you will have a problem in left speaker itself(cables or speakers)-start with cable changing and then speakers,
Make sure you use the sleeve as ground reference on the 1/4" connector then check that aginst the ring and or tip and then you should see something on the oscilloscope. Let me know if that works. Have you tried hooking up some speakers? We can live chat if that help you any. Let me know Guru Jay
