Question about Denon AVR-1705 Receiver

1 Answer

No subwoofer signal

I have two Boston Acoustics satellites and a subwoofer. I lose the signal after a few minutes of playing music or when I change the volume. I have tested the subwoofer with a different input (iPod) and it works. I am not sure why this is happening. Any advice on diagnostics or why this might be happening?

Your out put signal circut bord is shorted out. It happens when there is static feed back from output continuity to an electric overload inside the unit. Then when you have a shorted board then it will eventually go into a protect mode and nothing will work ...just the power light will turn red and blink.

Just a suggestion.....Get rid of it while it has a bad sub output signal. you can get some money out of it.
I can always use extra parts for the other denons I work on....call me if you want...630-742-6587

Boston Acoustics subwoofer keeps cutting out


Some subwoofers have a turn-on delay circuit at the input to prevent "popping". Unless the input remains at a certain level, the delay circuit turns off the sub. The only solution I have found is to change to another sub that is not so protective

Rattle when deep base played


If you can remove the rear cover check to see that the speaker mounting screws or nuts are tight. If they are the speaker is blown or defective. I would contact Boston Acoustics if it may be still under warranty or can be repaired. good luck

Boston Acoustics VR 950 speaker (tweeters) have static when playing music with a lot of piano. Clean as a whistle (no problems) with acoustic (guitar), though. Are the tweeters blown, or is there...


Don't blame the speakers just yet. Check your PC's audio controls to make sure it's not modifying anything and that your speakers are defined as speakers, not headphones.

Try running UNripped music to them. Solo piano is a difficult signal to reproduce.

Nice amp, huh? I have one plus some Cubes.

All static from the sound bar. adjustments don't help. tried different cables - that didn't help. System is not usable at this time.


The manual...

http://www.retrevo.com/search?q=Boston+Acoustics+TVee+Model+Two

Page 7

Distorted sound from the Soundbar.

Change the Trim Level switch setting to a higher number.
Check the signal source to be sure the distortion is not originating there. <<<<<<<<<

The woofer seems to have interference with its wireless signal.

Try changing settings of the Wireless ID switches on both the soundbar and bass unit. <<<<<<<<
The bass unit could be too far from the soundbar to get a good signal. Try moving it closer.

What is the source device that results in static? How is it connected?

I get a red light on the back panel labeled power. No green light. I don't think the PV 600 is working but when I run the channel check through my Pioneer THX receiver I hear sound. Any thoughts?


The PV600 and PV400 have auto-on circuitry that turns the subwoofer on when a signal is presented, and turns off if no signal is detected for 15 minutes.

Not knowing which Pioneer receiver you have I have dropped in the steps for No Sound from Subwoofer:

• Check that the subwoofer is connected properly, switched on and the volume turned up.

• If your subwoofer has a sleep function, make sure it is switched off.

• Make sure that the Subwoofer setting is YES or PLUS (see Speaker Setting on page xx).

• The crossover frequency may be set too low; try setting it higher to match the characteristics of your other speakers (see Speaker Setting on page xx)

• If there is very little low frequency information in the source material, change your speaker settings to Front: SMALL / Subwoofer: YES , or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on page xx).

• Check that the LFE channel is not set to -80dB , or a very quiet setting (see Bass Peak Level

on page xx).

• Check the speaker level settings (see Channel Level on page xx).

Regarding the Large vs Small assignment of speakers, what they mean isn't so much the physical size but the ability to handle real bass. Large if Yes.

The subwoofer isnt working but speakers are


You mean the right and left satellite speakers are working but the subwoofer is not. Try to adjust the bass control of the subwoofer at the back. Set it to full.

Came home after a storm and smelled electric burning and heard a hum from the subwoofer. now i wonder what the problem is and is it worth getting fixed.


I had almost the same problem. I was Playing music and my speakers kept on shorting out, i smelled burning wires and i look in back of my subwoofers and there melted. i just simply replaced the wires exept with a thicker 14 Gauge wire. But i dont know if your subwoofer is damaged or not. but i would try changing the wires.
