Question about Yamaha DSP-A1000 5-Channel Amplifier

2 Answers

No sound at all

Hi, A friend gave me a Yamaha DSP-A1000. I have hooked it up with guessing what goes where. I can get a buzz out of the speakers when I fiddle with the Coupler main. There were solid copper wire jumpers connecting main In and Out for both L and R. I took them out. The unit is not grounded, if it matters for getting anything out of it. I have hooked an ipod into the input jacks for CD using the bank of jacks on the left (looking at the back). I have no remote control. Like some TV's. I hope it's not required. Thanks! Mike

Hey those jumpers should be there always unless you would like to connect an equalizer. that buzz sound is normal, it's your main amp input amplifying. you remove that and you wont have any audio in all your sources.

The jumpers are there to connect the preamp section to the power amp section and are required for the receiver to opperate properly. Make sure the receiver is set to the proper input, in this case: CD. If there are A/B speaker connections, be sure the receiver is set to match the connectors you're using. If there is still no sound, profesional service will be required.

Own a Yamaha DSP-A1000. Center channel "died" this week. Everything had been working for years. Suddenly, the center channel stopped working (very obvious in DSP fields for Home Theater). Any...

If you run through the setup and certify it knows about the center channel first, then test it with tiones, then maybe swap the center speaker with another one you might come to an answer.

Be sure you are using the AUDIO OUT on the vcr then going into a AUDIO INPUT on the DSP A1000, this will allow the DSP A1000 to amplify the audio line level.

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.

Effect off

Dear Zforce, The Yamaha DSP A1000 has three different options of on-screen display. Try using the On-screen button on the remote control in order to remove the disturbing display. If this fails or if your remote control malfunctions then you should contact Yamaha for further assistance.
