SOURCE: Power but no sound

The cables going from the pre-out to main were just loose enough to cause the problem

How do I connect my 901 equalizer /speakers to the yamaha rx-v633 receiver?


Sorry, it doesnt look like you can hook up an external EQ while still using the amplifier section of the yamaha. Instead, You would have to use the preamp out to go to 901 EQ, out of the EQ into another stereo amplifier, then to the 901 speakers. Personally, to power the 901's properly, I'd use another external amplifier. You will barley get 75watts per channel out of the receiver to power the 901's

No sound at all. Power is on and all lights light up, but so sound output regardless of speaker selected or input.


I do not have experience with this particular amp. Generic trouble shooting follows:

Might it be that you have headphones plugged in? (Unplug them, they turn off the speaker output) You are absolutely certain of the settings on your amp? (check them again) Are you certain you have an input? (AM, FM, CD, AUX, other) (Make sure the input is turned ON and the source is properly selected.

Is the output protected by a fuse or fuses? (look on the back panel for fuses or fuse holder)

Everything that is suppose to be plugged in IS plugged in ... all cables are intact? Did you check them for contunity? You can check contunity with a flashlight battery, the light of a flashlight and a paper clip.

Speaker selection switches are pressed as appropriate. Speakers are connected to the appropriate outputs and they are ON. Speakers are of proper rating - and resistance? 4 ohm - 8 ohm - 16 ohm??? Any controls on the speaker are set at a neutral setting?

I'm sorry your device is not functioning as you think it should. These things are designed to work and generally, they are pretty good at it. Sometimes, they just break (stop functioning) It may be that you will have to take it back from where you got it for repair or adjustment. But I am hoping you have the headphones plugged in.

Standard speakers to the computer , low volume


You are getting low volume because there is no amplifier in those speakers. Computer speaker sets are powered -- there is an amp in one of them them which drives both speakers -- a computer audio output without an amplifier will only satisfactorily drive headphones.

Yamaha Dsp-A1000 5 ch amp Bought a used amp will be hooked to an awia reciever and speakers also have two subwoofers need help to install correctly witch connections to use


if you wanted to use your receiver as your controller and source then try to find out the receivber has got a bridge (jumper) between the pre-amp stage and the power amp stage. if your receiver does not have that, then you can just connect your receiver tape record out to one of your DSP inputs. subwoofers, the DSP has got a sub woofer out connector. you can use that (RCA type) to your sub woofers. put in series because DSP has got only one output for sub. or, you can connect your subs directly to the mains speakers, parallel connections. maybe one sub to your left and the other to your right channel.

Auto Shut Off After 3 Seconds...?


either your DSP output stage already damaged or maybe your speakers. have it both chekced for short. or worst both of them. DSP A1000 can drive as low a 4ohms on main channels but how is the power handling of your speakers? are you sure it has not exceeded the capacity of the speakers? or maybe you have over driven the speakers and they are still ok but your amp gut busted due to over drive. If the DSP amp is busted then it is due for replacement of power transistors and drivers. you can not disable the protection circuit. at least the design. it can be disabled by a tech person with a lot of modifications but i wont go for that or it can cause more damage to your equipments. i am from yamaha before and i have made conversions of protection circuits but it is too risky.

Please Help about a Yamaha DSP-A1


The A1 has an internal self diagnostic program which you can go through to find the fault. You can access the diagnostic program by simultaneously pushing some buttons on the front panel. The Yamaha service manual for the A1 tells how to do it and what the diagnostic codes mean. You can get a copy of the service manual on the web from several suppliers for a small fee.

The display problem is because the solderings on the back of the display are broken. To fix it you have to open the amp and redo the solderings (there are about 50 or 60 of them). There is a Youtube video that shows how to do it. I have fixed this on my DSP-A1.
I also have the problem with the motorized volume control. I have tried cleaning it, and it works for a few days, then it's stuck again. I guess I will have to replace it to have it fixed permanently. The part number is VZ621400, a new one costs about 40$.
