My a102jamo surround sound speakers and working


The Jamo speakers need an AV Receiver to drive them properly. The TV doesn't have the correct outputs nor does it have the power required.

The Jamo kit consists of a powered subwoofer ans 5 small surround speakers. Each surround speaker needs to be powered by the speaker output from an an AV Receiver. The subwoofer should also be connected to the receiver, but the connection is a phono/RCA lead from the receiver's "Sub Out" socket.

Your TV connects to the AV receiver via the Optical out.

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.

I have marantz Av surround receiver model SR301 I have tried a lot but I am having sound from only 2 speaker when I put in setero mode but when I put in surround no sound from any speakers I checked all...


First off you will need to do a little bit of trouble shooting. Is the source (dvd, Blu-ray, cable box, etc...) plugged into the receiver with the standard red and white RCA cord or by an optical (toslink-fiber optic) or digital RCA (orange color code). If you are connected with a standard RCA cord then that it your problem and you need buy digital cord that both the source device and the receiver can accept (toslink - http://www.we-supply.com/browse.cfm/optical:-audio/2,779.html or Digital RCA). If the connection is now correct then you need to make your receiver do a "test-tone" to insure that a signal can be sent to every speaker (this is an internal test that just checks the speaker connections). If the tone tone operates correctly then you know the amplifier is functioning. If both of the mentioned things are now done and still not surround output then you need to check the internal menus on your source device and make sure that it does not require you to manual change a setting in the audio menu to make it work (i.e. change from 2-ch 44KHz to 5.1 or 7.1 or Dolby Digital or AC3 or some other surround sound protocol.)

My Sanyo DP23845 23 In. LCD Television does not have any options under set up beside color-how do I add channels?


HDTV inherently provides a superior sound quality simply because the sound of HDTV is digitally transmitted. The difference in sound between an HDTV television and an analog television is rather noticeable. In fact, it is directly analogous to the difference between the music on CD's compared to the music on audiocassette tapes.

The difference in sound quality provided by HDTV televisions and programming does not end there. Many HDTV programs are also broadcast in Dolby Digital 5.1 surround sound, but in order to take full advantage of this technology, it is necessary to have the right equipment.

Dolby technology has been created by Dolby Laboratories, Inc. This technology is the most renowned provider of digital audio technology. Also, Dolby Laboratories is known for reliable and superior products. For these reasons, Dolby Digital Surround has become the standard for HDTV. Many television manufacturers substitute their own surround sound systems, but they cannot live up to the reputation and performance of Dolby. Therefore, it important to check the specs on an HDTV television before buying in order to ensure that it uses Dolby Digital Surround.

When using Dolby Digital Surround Sound, there are three options for set up. The first option is to buy a television with high quality center channel speakers, woofers, tweeters, and Dolby technology installed in the television. With this option, it is unnecessary to buy addition equipment to take advantage of Dolby Digital Surround Sound.

Another option for taking advantage of the Dolby Digital Surround Sound with an HDTV is to connect an external set of surround speakers to the television. With this option, the surround sound set up includes a front pair of speakers, a surround pair of speakers, a center channel, and a subwoofer. Sometimes, the front speakers are "powered towers." This means these towers include subwoofers.

The placement of these speakers is very important for the quality of the surround sound. The Center Channel Speaker should be centered either above or below the television. The Front Left and Right Speakers should be placed in an arc formation in line with the Center Channel Speaker. The Surround Left and Right Speakers, on the other hand, should be placed to the left and right sides behind the listening position. Many people choose to wall mount these speakers.

The third option for taking advantage of the Dolby Digital Surround System included in an HDTV television is to use an external set of front speakers can be connected to the HDTV television. This configuration is useful if there is not enough room to set up the external surround sound system and the HDTV does not come with Dolby Digital Surround installed. This isn't true surround sound, but it is a viable alternative to those who can't take advantage of the first two formats.

The audio and video outputs of the DVD or VCR can be connected to the AV receiver's video outputs. If a separate DVD and VCR need to be connected, one can be connected to the VCR1 connection and the other can be connected to the VCR2 connection. The AV receiver's VCR video and audio outputs should then be connected to the audio and video inputs of the DVD and/or VCR. In this way, the DVD and/or VCR will be able to record video signals that come through the AV receiver and the VHS tapes and/or DVD's will be able to be viewed on the HDTV.

To take full advantage of the Dolby Digital Surround Sound technology, one of the video outputs of the DVD player and/or VCR needs to be connected to the AV receiver. The digital coaxial audio or digital optical connection must also be connected to the AV receiver.

How do I connect my CD player?

A CD player can be connected to an AV receiver. The CD player's digital audio outputs can be used to connect the CD player to the AV receiver. A CD-Recorder can also be connected the AV receiver by using the Audio Tape Record/Playback input/output loop connections. In this way, the CD-Recorder will be able to function much like a standard audiocassette deck.

What else will I need?

Besides the basic electronic equipment needed to set up Dolby Digital Surround Sound, it is necessary to have connection cables. This includes video, audio, and loudspeaker connection cables. These cables need to be at an appropriate length in order to set the speakers in the proper position for optimal surround sound quality.

I have this receiver hooked up to a Vizio LED tv and a Vizio Blue Ray using HDMI cables. The surround sound works from the speakers while watching a dvd (HDMI -1 connection) but I have no surround sound...


AV cables don't pass surround sound through, they are pretty much just left and right stereo. You need to turn pro logic on on the reciever to "pretend" to play surround. The better option of course would be to use a digital signal like another HDMI cable or digital optical audio from the cable box, if thats what your using.

Can I connect a Computer to a Techwood DDR 94 AV Digital Surround Receiver so that I can listen to radio stations online?


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

Why cant I supply my onkyo surround sound system


You need to assign the HDMI input(s) to the functions they represent, using the Front Panel Tuning/Preset control...

If you connect a video component to an HDMI input, you must assign that HDMI Input to an input selector in Setup.
For example, you could assign the “DVD” setting to “IN1”, and assign the
“CBL/SAT” setting to “IN2”.

Likewise if you use digital audio inputs...

Assigning the Digital Input
If there’s no sound, press the [DIGITAL INPUT] button repeatedly until sound is heard. The digital input is now properly assigned.
If you connect your DVD player to the AV receiver’s COAXIAL 1 DIGITAL IN, and your cable/satellite receiver
to the COAXIAL 2 DIGITAL IN, as shown, it’s not necessary
to assign the digital input.

Bose 901 Hook up help !


The use of 901's in any digital AV receiver setup for anything EXCEPT STEREO listening through the 901's alone requires you to have a separate amplifier for them and to avoid having to use a Tape Monitor.

That is because if you activate any Tape Monitor circuit at all, you will kill any digital sources. That is a function of AV receivers in general, nothing to do with 901's. However, you can still draw the Front Left and Right signals out of any Pre-Out (with a Y-cable set, looping the Pre Out directly back to the Main In) or Tape Out jacks (remembering to NEVER activate that monitor on the receiver), go into the Active EQ's Amplifier Connections; then Out of the EQ's Amplifier Connection to a separate amp and attach the 901's to that amp. This way you won't introduce proprietary and potentially damaging Active Equalization back into anything in the AV Receiver with its conventional speakers.

Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them. On many, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others, you may have to borrow the signals from a typical Tape- or Adapter-Out RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won't have to switch IN. The signal Out is always there regardless of the monitor state.

The AV Receiver can still drive the Center, Surrounds and the Sub(s) as it is designed. This is how mine is wired.

Come to think of it, you could still have conventional Front L&R speakers on the AV Receiver, but why? Maybe one would prefer the 901's for music and some other speakers for surround. Level matching with the 901's to conventional front speakers would only be possible if the separate amp has its own volume, but it would work. Maybe I'll try it someday. None of my current amps has a volume control.
