I purchased an RSP-1068 and RMB-1075 two years ago. They are hooked up to Paradigm monitor 11's, CC-370, ADP-370 and PW-2200 subwoofer. 90 percent of the time this system is used for TV and movies. About a year ago I noticed that the subwoofer was not always automatically turning on (up to 50 percent of the time). In most of these cases the subwoofer test tones were unable to trigger the subwoofer to turn on. I have my speakers set to small and the crossover set to 80 (note: I have maxed out all the 1068's subwoofer levels). The only way I have been able to solve this problem is by quickly turning the 1068 off and on. I have sent the unit to Rotel but they are unable to duplicate this intermittent problem. Also, the subwoofer has functioned normally when hooked up to several other systems. Has anyone seen this before or have any ideas?

If you turn your main amp off and crank the volume, will the sub eventually kick on? If you turn your sub auto-on feature off does the sub output always work?
Trying to figure out if it's a sensitivity issue on the sub input or a problem with the sub output on the 1068.

unfortunately, the subwoofer does not have an on/off setting. It's auto detection or nothing. The volume of the 1068 does not seem to trigger the unit to turn on. As mentioned earlier the only thing that seems to work is turning the 1068 off and then on again. I recently sent both the 1068 and subwoofer to Rotel for evaluation. They had the units for 2 weeks and were unable to reproduce the problem. Upon their return they worked perfectly for several weeks. I thought the problem was solved but the units soon began exhibiting the same problem. I don't know if I'll be able to figure this one out.

It seems that lots of subwoofers on the market have sensitivity issues detecting enough signal to turn on. (Why, oh why, don't sub manufacturers just use 12 volt triggers?) If a user has this issue, most subwoofer companies recommend turning up the subwoofer output on the preamp or receiver, then reducing the volume control on the subwoofer.
In the case of the 1068, that would mean going into Setup -> Test Tone, and raising the subwoofer setting. You might start with the maximum value (+9 dB) to see if it works. If so, you can then reduce it to the lowest setting at which it reliably triggers the subwoofer.
Also, to get the most signal strength from the subwoofer output on the 1068, connect both subwoofer outputs to your sub. (If your sub only has one input jack, get a Y-cable to connect both outputs to the single input.)
That should do the trick, unless of course there is a hardware problem with either your 1068 or the subwoofer.Comment

OK, I am not sure what is going on with my system. But, it is weird.
I was just running the AVIA calibration DVD, calibrating the speaker levels when I noticed something really weird: The mains, Center and Surrounds do not seem to have a high pass crossover working, even when they are set to... -
Greetings,
I have owned my 1068 for about a year now. This weekend, it decided not to output the L & R signals anymore from any source. When I switch it to 2 ch. mode, all I get is a subwoofer output...no sound from the front L&R.
It automatically picks up flags... -
I am using a demo 1068 processor until my 1098 arrives and have a DVD and HD DVR from Time Warner attached with component cables and then outputting to the TV through Monitor out with component cables. When watching the Cable input, every few minutes the video will drop out for several seconds and the... -
G'day,
I am having an issue with my RSP-1068 and progressive scan inputs.
I have three video input devices hooked up to the 1068: a set-top box, a DVD player, and an Xbox (on V1, V2, and V3 inputs respectively). The 1068 is then connected to my TV (a Sony LCD). All inputs... -
Hi Guys,
My RMB-1095 or RSP-1068 has developed a problem over the weekend. The left front channel stopped working so I reversed the front L & R pre-outs to see if it was amp or the processor but after doing this both speakers started working again. I swapped the pre-outs back to their...
