Re: using headphones with my yamaha dsp a595a amp

If you turn speakers A and B off together, there should be no sound coming out from your speakers(be sure that you do not have the amp operating in surroundmode.). The headphone cct in this amp is not affected by speaker switching and remains on all the time. v

Yamaha DSP-AX1 ,. When turning on it only stays on about 4-5 sec. then shut off. Bob

Is this new equipment or a new problem on working equipment?

Impedance Selector in between settings

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

My yamaha DSP AX1 amp does not work when audio is connected via optical or coaxial any suggestions how to correct this. no sound comes from any speaker except the subwoofer.

Are all the speakers turned off (set to None) in the speaker menu.(except the sub)?

2 channel direct analog stereo may still work, but any surround modes will use the speaker settings and the full DSP digital section.

Check also the input mode isn't incorrect - although if the sub is wired correctly and gives sound this can't be whats wrong.

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.

Problem with Yamaha Amplifier 361

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.

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.

Distorted sound

This is an automatic high end amp. Make sure you are using 8 ohm speakers. If the connections are correct, also use good quality speaker wire.

If this makes no difference, it seems that it would need to go to the repair shop.
