Have you isolated the problem to the equalizer only? By that, I mean remove it from the signal chain and bypass it completely. That's the first thing.Does the system make noise without it in? If dead quiet when removed then you go to step two.
If the noise returns when the EQ is reconnected, you should eliminate crappy or broken cables, connectors etc. Replace with a known good working set. Still there? Buzzing infers either a ground issue or some kind of power supply problem, only if the previous stuff is eliminated. Do this first, then ask again.

How can i hook-up a 901 series vi equalizer to a str-de897?


I own 901's(since new) with the active equalizer powered with a non-Sony surround sound receiver.

Basically, you use the MD/Tape in/out jacks to route the signal to the Bose active equalizer. Switch the Tape Monitor switch if no sound is heard.

Here are some references.
https://docs.sony.com/release/STRDE897.pdf http://products.bose.com/pdf/customer_service/owners/901_guide.pdf

Connect equalizer cables (4 total) to the MD/TAPE section of your receiver. OUT from the receiver to the equalizer IN and Out from the equalizer to IN on the receiver.

One issue with the equalizer running through the MD/Tape jacks is that it may affect any other speakers hooked up to your system.

Radio and CD player both emit a hissing or buzzing noise through the speakers like there is poor reception. However, all the local signals are found and play just fine, just the hiss!


The CD player cannot suffer from poor reception, so if you are having the same hissing / buzzing sound from the Bose system irrespective of the source you have selected , its is coming from the preamp / amplifier section.Also could be coming from the electronic source selector in the preamp section.You will need profession help

Speakers have hissing noise coming out of them


Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.

Cant get rear speakers to Work AVR 745 7.2 Surround!!!


Another way to solve this rear speakers problems is to go to the equalizer and have the system recognizes the sound coming out of all speakers. The AVR 745 comes with a microphone on the stick, using that to run the manual equalizer. It is the manual equalizer will set the rear speakers.
