Techwood 400 watt Stereo Receiver PLR85

accidents happen but you can not expect any one to know what it did to the equipment if none of us ever had one .

Hello Christine, so you mention your Techwood
would have possible problem in the amplification stage
I suggest you disconnect all the speakers and check if it continues to protect, if not, see reconnecting the speakers one by one and testing, control the speaker cables are in good condition
If you repeat the Proteccion fault, I suggest you look for a specialized technical service
I hope you can solve the problem
Greetings Franco Dosil

Hola Christine, por lo que comentas tu Techwood
tendr?a posible problema en la etapa de amplificaci?n
Te sugiero que desconectes todos los parlantes y comprueba si se sigue protegiendo, sino lo hace, ve volviendo a conectar los parlantes de a uno y pruebas, controla los cables de parlante se encuentren en buenas condiciones
Si repite la falla de Protecci?n, te sugiero que busques un servicio t?cnico especializado
Espero puedas resolver el problema
Saludos Franco Dosil

This receiver has 100 watts per channel. If b side speakers aren't working you may have them hooked up wrong. Try connecting the B speakers to A terminals to make sure speakers are functioning. Please see the user manual below for wiring diagrams.

Generally speaking, an amp protects itself from heat, shorts and overloads.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

Yes. You can. First, you need a cable that has a stereo pin called stereo jack (the type that has on ear phones/head phones) on one end and component cable terminals (the type that comes with video/ audio left and right) on the other end. To further explain, these terminals come in yellow red and white colors. You only need the red and white ones. This is available at electronic stores. Otherwise a person who service electronic equipments can easily make one. Basically, this cable will have a stereo jack (small one) on one end and split into 2 cables with the red and white terminals. Once you have this cable, connect the stereo jack to the ear phone socket of your computer and connect the other end to the audio input of your Techwood receiver. You can select anyone (CD, DVD or TV). These inputs are right above the speaker wire connections. Be careful to connect to the socket that say "in" . Now, let us assume you have connected to the CD, select your source as CD on your techwood receiver. Play music on your computer and you should be able to hear the output through your Techwood receiver. Good luck

I have had the same problem.

You have a faulty cooling fan.

The system senses the fan isn't working, and knows that without it, it will over-heat. So it goes into a "self-protect" mode - hence the green light.

You need to replace whatever part of your fan has gone bad.

I can think of no reason any amp pushing 120 watts would not work with 901-VI's. They're very efficent and will probably play louder and cleaner than you would ever need. As I recall, my old series IV's have no maximum amplifier rating specified, but I did blow up a bridged Carver M-400 Cube (pushing 400 watts to one speaker with a DVD-Audio of Yes - Fragile cranked dangerously high) with them. I'm convinced my speakers are indestructible in any home application.

Keep in mind that whatever you decide to use as your control/amplifier section, a pair of 901's need a dedicated stereo amplifier. I suspect you're thinking surround sound so a receiver with separable preamp/amp channels, due to the Activbe EQ, would be needed and as far as I know they don't exist. A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver and the 901's amp channels. My receiver controls everything and just drives the Center and Surrounds.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. 120 clean watts is good. I'm using only 110W for mine.

A Carver M-200 is a fine, efficient amplifier that would have you cooking just fine (2x100W).
