SVS SB-1000 Pro trigger via AVR USB port?

1818 Views 10 Replies 5 Participants Last post by  bobknavs,

Is it possible to trigger my SVS via the USB port on my Sony AVR that turns on when the receiver powers on with my TV? If it is possible, can anyone link a cable that I can use for this purpose...Google searching for this really brings up absolutely nothing. 👀

Your Sony AVR lacks a 3.5mm 12V trigger output?

(The SVS SB-1000 Pro has one.)

Correct, it's a DH590. #meh

My Polk PSW-505 has an auto setting, but it doesn't work unless you crank up the volume to a certain level, let it activate, then turn the volume back down...it's annoying.

I don't know about the PSW-505, but Hsu Research claims that if you turn one of their subs on but with no input signal, that the power draw is about the same as in standby mode (sleeping, waiting for an input to activate it). Apparently the switching mode amps dissipate very little power when no input signal is present.

In other words, you may be OK to just leave the sub on all the time. If you can access something like a kill-a-watt (power usage monitor), you could check, if you can't get the information from Polk.

This is a convoluted solution but you can get one of those power saving smart power strips (APC P8GT is one example) that will turn on and off specific outlets when it senses a specific outlet is drawing power. Plug your AVR into the sensing outlet and then get a 12VDC power supply wall wort and plug it into one of the automatically switched outlets that will turn on or off with your AVR. You will probably need to change the connector on the wall wort 12VDC power supply and extend the wire to your sub.

The "Auto" feature on a sub means the sub is always on but in standby mode, and signal / lack of signal from the AVR causes the sub to switch out of / back into standby mode.

With a 12V trigger, the sub is powered completely on / off by the AVR to which it is connected whenever that AVR is powered on / off.

I prefer a trigger to the "Auto" feature. YMMV, of course. :)

USB to 12V trigger input? - According to posts 6, 7 and 9, it's worth a shot.

I will see how well auto works when my new sub arrives. My current Polk must be turned up to a much higher than comfortable volume to trigger the auto on, and if left in on position, it has a sight hum and heats my bedroom.

Here is SVS weekend support chat response...I am offended it takes them a whole 4 seconds to respond to support chat on weekends!

(08:42:00 PM) Paul Anderegg: Can my SB-1000 Pro on-trigger be activated using a USB port on my Sony AVR that turns on when the AVR is powered on by my TV? Do you sell a cable that would work in such a manner if it is possible? :)

(08:42:34 PM) Paul Anderegg: :)
(08:43:59 PM) Steven F. Elsbury: The trigger input on the SB-1000 Pro is designed to work with specific voltages generated by the trigger output on some AVR's. I do not believe it would work in this case.
I recommend using the standard standby mode by setting it to auto. This will have the subwoofer turn off after about 30 min of no signal, and turn on when it gets an audio signal from the AVR.
(08:44:36 PM) Paul Anderegg: OK, thank you...I figured USB being 5v it might be a usable source :)
(08:44:55 PM) Paul Anderegg: have a good weekend!
(08:45:09 PM) Steven F. Elsbury: Thanks so much Paul! You do the same! :)

I missed the bit where you switched from the SB-1000 to the Polk.

I have no experience with the SB-1000, but I'd make a small wager (5¢) that its auto on feature will work OK, unlike the Polk.

The auto on feature of my two Hsu subs works very well.
