Yamaha RX-V667 Sub Out signal is low

[stefan7219]

Hi,
I have Yamaha RX V-667 AVR connected to my 5.1 speaker system.
The sub in this sytem is a Velodyne Impact 10. The sub has an auto On feature that can't be disconnected or bypassed (I think)
I can't seem to get enough signal to the sub consistently and the sub is cutting in and out and it does not turn on at low volume levels. As soon as I increase the volume to approx -32 dB the sub turn on, regardless of audio content. the 5.1 system is set up with YPAO.

All speaker are set to small and the crossover freq is set to 200. The crossover on the sub is also set to 200.
The sub is connected with a single subwoofer cable

Any suggestion on what I can try with the amplifier so I can get a stronger signal to the sub.

Also, if somebody could explain why the sub turns on at higher volme levels I would find that very educational.

Thanks in advance

Sincerely,
Stefan

Try setting the sub to 80hz. And your mains and surround to 100. See if that helps. Also, are you sure you hooked up the sub to the SUB OUT on the reciever? And make sure it's hooked up with the main zone, not zone 2.

Don't ask the same thing in different forums.

My apologies. Did not know the rules and it will not happen again.
