My powre subwoofer in not working with the sherwood r-945. Can you help.

Hello Kingsley, you can connect an active SubWoofer to the subwoofer output, which is located on the back panel of your Sherwood
This model does not have an output for passive subwoofer (without its own amplification)
I hope you can connect and enjoy a good sound
Greetings Franco Dosil

Hola Kingsley, puedes conectar un SubWoofer activo a la salida de subwoofer, que se encuentra en el panel trasero de tu Sherwood
Este modelo, no trae salida para subwoofer pasivo (sin amplificaci?n propia)
Espero puedas conectar y disfrutar de un buen sonido

Describing video connections lends no clue why audio isn't working.

Cables between sources and compatible units rarely need to be physically modified.

Splicing headphone outputs designed for nominal 8-ohm impedance speakers to a 47K-ohm (typical) RCA load is not a good idea but it might work on the Sherwood because this receiver does not automatically silence your other speakers when the headphone jack is installed.

There is NO other volume-controlled output to choose. Try it.

surround and subwoofer may not work if there is an additional graphic equaliser operating.
1. check in your receiver speaker setting ensure your speaker setup doesn not have subwoofer set to NONE. this will block any signal to your subwoofer socket.
2 when you select your surround sound setting setup, ensure you select the speaker mode you want, if there is a multicontrol knob, cycle through the choices
select subwoofer mode and set it to yes.
if you have set-up small speakers S in your speaker settings then it could be that subwoofer is set to yes automatically if you have large speakers L, subwoofer has to be set additionally in the subwoofer setting.
3 test subwoofer on alternative device to test it is working ok
consult manual on enjoying surround sound and adjusting the speaker settings.

Yes on the back panel

if bose unit has built in amplifier .Then your sherwood would have to have a variable RCA output jacks in order to work with sub.Then bose audio input RCA cable would connect there.If bose unit does not have built in amp .Then you would connect sherwood left/right speaker outputs into bose left/right inputs .Then other bose speakers will connect to bose unit

HAI , REPLACE THE VOLUME CONTROLS.

The Sherwood R-945 has at least 6 fuses inside - any one of them could keep the system from powering on properly. The lowest power fuse is rated at only 35 MILIamps, I believe ( it's element is barely visible to the naked eye ). Check that all fuses are intact (with the power off)

My R-945 unit kept shutting itself off directly after powering up - turned out that one of the speaker wires had a fault - (found after hours searching with voltmeter). Check that all Inputs / Outputs are secure.

Good luck with yours!

disconnect everything from the unit and see if it still does it.
if it does i would check the output transistor (ic).
