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?

Re: speaker distortion on high end
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 ...

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.
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???
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)
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.
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.
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.
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!
Have the same amp and speakers, had some trouble getting the imput signals sorted from the HDMI input as im using a PC with HDMI output from the mother board and Windows Media Centre. havent tryed using the mic set up yet.
Did you resolve the issue? have you tried the 7.1 outputs
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.
