The coupling capacitor on the phono input is possibly become leaky. Try replacing any small electrolytic capacitors you see near the input within the amp.

How do i hook up bose accustimass speaker to my radio?


Acoustimass speakers need to be driven by a Hi-Fi amp/receiver or AV receiver. So the thing that's driving them needs to be an amplifier.

Unless your radio is also an amplifier then the radio and the Bose speakers are not directly compatible. There's no suitable output on the radio that generates the correct signal in sufficient power.

Denon avr-1804/884, speakers Bose vcs center, Bose acoustimass 5 series 3 speaker system, Bose 201 series 4. All speakers play in test mode, with tuner, dvd, phono, cassette. The left side speakers will...


You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

Have this Bose system connected to my Yamaha a/v receiver


If you have it literally conencted the way you say not much good will happen.

The speaker OUTPUTs for the Yamaha feed the INPUTS on the Acoustimass Module then the satellites branch out of the Acoustimass Module's OUTPUTs.

Acoustimass module
Bose® recommends putting your Acoustimass module at the same end of the room as the
television monitor. To prevent interference, keep the module at least 2 feet (.6 m) from the
television.
• You may hide the Acoustimass module behind or under furniture, but do not block the
opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
corner.
• Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the
cable connection end, remove the cover by gently pulling it away

Move the sub closer to a wall or corner to increase the bass.

This is a SYSTEM and as such is not designed to be pieced out or separated. I don't recommend that you try it that way. I doubt it will improve the sound.

Receiver Sr5200 shut down in 5.1 mode


chances are you have the volume too loud and the speaker wires are crossed.
all speaker wires need to be with the positive on the right and negative on the left if you have them anywhichway than it will work on low volume and not a very good sound.
look closely at the wires and they should have a red or so color on one side or the wire jacket itself will have a round side and a flat side

Bose speaker connection


The Bose systems are SYSTEMS for a very good reason. They're made for people who want good sound but don't want to manipulate the hardware much. The speakers and amps are designed for each other ONLY, not only electrically but through soundshaping to provide the smooth final result. The design is for you to feed the electronics a Line Level source and the magic and distribution happens internally. These are NOT mix 'n' match components. The special connectors are a clue. The Yamaha will probably blow them up if you manage to succeed with your plan.

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.
