Hello, I moved home and put my Jamo S 250 HCS 21 back together. Two prblems occured: 1- The Sub 200 doesn't seem to connect to the other system, I hear no bass to the sound. How do you connect this device to the rest? And what cable is needed? 2- When switch on and only working with the S 250, a very distracting buzzing sound is heard in the background.. I hope you can help me. Thank you Alexia

It's the receiver, same prob here. The level of bass through the sub is negligible too. So my guess is it's either related to the crossover or the passthrough in general.
Looking for a missetting or workaround.

how do you turn Simplink off?

SOURCE: No system configration display on AVR3300 since moving.

Make sure the two switches on the remote are all of the way to left most position before you try using the SYSTEM SETUP button - if the AVR is going into SETUP, the LCD display should be saying "SYSTEM SETUP". (I think that model does - most do).  also make sure that the Composite or S-Video on the TV's input 1 work from something else like a VCR, DVD player, ETC. rule out the TV and the cable first.

Check your speaker settings in Setup menu / Speaker Setup / Manual / Config (and then in this submenu also Equalizer).
In Config, choose where should low frequency sound go - subwoofer and/or front speakers (if they are big enough). The settings are: Bass Out: SWFR/Front/Both.
Also check Subwoofer phrase in SWFR Phase.
Check settings of all speakers, they can be Large / Small / None. If small, frequencies lower than "Crossover" settings, will not be put on them.
