Panasonic SA-HE70 Sub Out Problem and Standby

My SA-HE70 has a problem with it's sub out. I have to pull the phono lead to one side on the back of the amp to stop it buzzing, and sometimes it just starts buzzing for no reason. I don't think its the sub (which is a amplified), so I was wondering if anyone knew if it is a problem that can be fixed, or should if I should just get a new one. The other problem is that you can turn the thing off by just tapping the case. Seriously not right!! Thanks for reading and for any replies.

Subwoofer channel no longer has output

Is your sub powered (amplifier built-in)? If so, connect your MP3 player directly to the sub input and see if you hear audio. If you do hear audio, check for cable problems from Panasonic to sub input. If the sub is unpowered then it's either the speaker wiring, an intermittent sub and/or your Panasonic at fault.

Looking for manual for pioneer sw200 powered subwoofer

Most subwoofer have a left and right phono/RCA sockets. The amp should have a sub out phono/RCA plug. The sub should have come with a phono/RCA lead that will connect these - one plug to two plugs.
Apart from the mains plug that's all there is really. You may have to switch the sub socket on the amp on.

Or you can get one of the cables from places like below:

How to hook up external amp need to know how to run jacks to the amp and speakers which out put for amp to run the front speakers on a panasonic sa-he70

Manuals help.

Register and download the manual for free at

Not knowing anything about your 'external' amp or how you want it to function the only thing you could do is feed it the analog stereo output of the SA-HE70 from one of its OUTs (Tape or VCR). It won't be volumed-controlled by the SA-HE70.

Panasonic sa-he7,no sound from sub output,im using a samsung subwoofer of impedance 6

Have you looked at the manuals?

If the unspecified sub isn't self-amplified it won't work with this receiver.

If it IS self-amplified you still needt o set up the receiver to run a sub.

To smarthome2 Regarding the panasonic SA-HE70 overload issue. Is there any place where I can get a free service manual or schematic to troubleshoot this myself?

Not very likely. Even to find one is a tough job. If you do find a source, expect to pay between 20-30 for it. I will look as well for you. If I find it, I will post the link or get a pdf if lucky!

Working the Sony STR-DE475 5.1 Channels Receiver

It has a dedicated sub out. you need a phono connection on one end for the amp and the other end must have a compatable connection to your sub.

You will need a phono connection to the amp from your TV. You can utilise a scart lead that has phono outputs however a TV with audio outs (the red and white leads) is the default option.

Using computer speakers with the panasonic sa-he70

I had a similar problem. In order not to mess up the jacks from the speakers I bought some mini jack to stereo rca adapters. I cut off the rca jacks from the end and then is just a matter of figuring out witch ones are left and right channels. For the subwoofer it's best to figure out which one is the sub channel so you don't have to cut off the rca plug from that one.
