Question about Onkyo M-282 2-Channel Amplifier

Speaker distortion on high end

Recently purchased a pair of Bose 901 Series IV speakers. There was distortion on the high end. Tried hooking the Onkyo M-282 Amp to another set of speakers and it does the same thing. Quite often the sound would drop out of one speaker. I would tap the amplifier and the sound would come back. Could it be speaker wire or does it sound like something is wrong with the amplifier. The amplifier is also pre-owned.Can anyone help?

    replace the speaker wire first, with new wire- 18g will do. Maybe that'll solve your problem, but it sounds like a loose connection or cold solder joint in the amp. Unless you know what to look for, you need a tech.

Sounds like classic dry joint on speaker terminal ROTELS are well known for it,if you can use a soldering iron or know someone who can resolder the pins where these terminals are connected,always make sure amp is unplugged from wall socket before ...

How to hook a carver TFM 45 to a Marantz AV 8003 pre amp with Bose 901 speakers thank you very much


The output of the Marantz will go to the input of the Carver. The Bose EQ has to go into a Tape Monitor on the Marantz, or, you can connect the Marantz output to the Bose line in(not tape in). The line output of the Bose, to the Carver input.

Is there anything else I'm missing?

I just connected two sets of 901'a to Sansui G901 receiver. The sound is TINNY no bass at all. I've tried different connections and nothing seems to work. I've used two different EQ from bosse series


Either there is NO bass on the recordings (if you listen to it with headphones does it have bass?) ...OR...you've wired them out of phase. Connect only one(1) Bose 901's to just one side. Is there bass? Then connect the other side. IS there bass? If not reverse the phase (+ /- connections) and see if the bass comes back. Once that is done and there is BASS, then add the 3rd and then the 4th speaker. .Are you sure your Sansui can handle a lower than 4 ohm load???

What will happen when I change speakers from frequency response 60 to 20000HZ at 60 Watts to a set of speakers from the same manufacturer to frequency response 60 to 16000HZ at 75 Watts. Everything else...


You will not get more distortion, in fact possibly a little less because the newer speakers have a higher power rating and can thus handle more power without cone breakup.
However - you indicate the the higher powered speakers have an inferior frequency response with the high end reduced from 20kHz to 16kHz - which is very surprising. This will mean that while not being any more distorted, the system will sound just a little less crisp and sharp at the high frequency end of the spectrum. Mind you, most adults over 25 - 30 years or so have impaired hearing above about 15 kHz, so chances are the difference in sound will be completely inaudible to many listeners :o)

I have an Onkyo A-7055 amd want to hook up two speakers. Looks like a dozen connectors in the back of the unit... which ones to use. If I experiment is there a chance I could blow out the unit?


Do you mean you want to connect 2 pairs of speakers, or just 2 speakers like you say in your question? There are 4 pairs of screws on the back of your amplifier on the upper right side of the rear panel near the fuse cap and the AC outlets. Each pair of screws will be connected to one speaker. Your Onkyo can be connected to 4 speakers. If you want to connect only 2 speakers, use the screws labeled "SPEAKER A" and connect the speakers to the left and right channels, and make sure you connect the + speaker wire to the screw with the red marking around it. Connect your other speakers the same way, one speaker per pair of screws.

How do you connect a nad c270 amp to the bose 901 series vi equlizer and system/


Bear in mind that 901's require exclusive use of any amplifier they use. You shouldn't expect to use conventional speakers alongside them on the same amp. The reason is that the 901's require the use of their dedicated Active Equalizer to shape the frequency spectrun to match their drivers' response curves, resulting in a flat sound output. Applying that kind of equalization to any conventional speakers will sound to sharp at the extremes and may even potentially damage them.

For connection I would run a pair of RCA cables from the L&R Audio Line OUT of whatever preamp or source you're using to the Active EQ's Line IN; then the EQ's Line OUT to a NAD amp's Line IN. DEselect any Tape options on the Active EQ, attach the 901's to the new amp, set the NAD volume controls pretty high (and leave them alone), run through any level setup procedures in your control electronics for volume, etc and you're done.

There's no reason you can't use the 901's in ALL of your audio experience.

Try this:

Remove the short plugs from the Adaptor jacks. They claim you can record some of the effects (surround, dbfb and tone) from these jacks so that implies it's late in the preamplification path. The question is - did they place it after the Volume Control, too - as many other receivers with jumpers do?

Take an RCA pair from the Adaptor Out to the 901 Active EQ's Line IN; then the EQ's Line Out to a separate amp's Line IN. Attach the 901's to the new amp.

Because we don't know if the Volume Control is in the path at this point, find yourself a CD with a long, low fade-in just in case the signal is at maximum power here. Be ready to Pause it if it gets too loud.

If the Volume Control affects it ok, then get yourself a pair of RCA cable splitters and place them where the Adaptor Jumpers were with the extra leads going to the cables we ran to the 901 EQ at first. That way the receiver still keeps the program internally for its own speakers and the 901's get it, too, but without modifying what the receiver sees.

If the volume control on the Sony isn't in the Adaptor loop you'll have to use the Pyle's volume control. But you could still have the speakers that are directly attached to the Sony useable at the same time.

I would like to know how to connect my Bose 901 to my Yamaha RX-V765 AV Receiver.


Ahhh, the good ole Bose 901. (I like those)... And you want to connect them to the Yamaha RX-V765 AV receiver. That should be a piece of cake. I assume you only have two Bose 901 cabinets. If so, you simply need to connect one end of your speaker wires to the terminals found on the 901 cabinets, and the other end of the speaker wires need to go to the Front Left and Front Right speaker outputs of the RX-V765. The RX-V765 is a 7 channel surround receiver. Weather you run it as a 7 channel theatre or as a more classic 2 speaker configuration, you will want to run the 901 cabs from the Front L and Front R speaker outputs, unless for some reason you want to specifically use them for any of the surround channels in which case it will not harm anything if you use them for surrounds - it's just that if you're simply wanting to use them as your principal speakers, you want Front L and Front R.
So connect them as I explained, power the receiver up, put on your favorite CD and enjoy!

Hi. I would like to connect a Bose controller between a pair of Bose 802 speakers and a Studiomaster Powerhouse 300 MIXER/AMP. The diagram on the top of the controller shows the amplifier connected just...


Tech data sheet with diagrams:
http://www.bose.com/pdf/professional/802III_techdata.pdf

In a nutshell, the controller would go between any preamp Stereo OUTput and a dedicated amplifier INPUT. You really don't have much choice in the matter. The 802's and their controller are part of an inseperable system.

The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.


I don't have any data on your mixer/amp but if you can't insert the conroller logically between the mixer and its amps then you'll have to get separate dedicated amplification for the 802's, with the controller between the mixer and that amp.
