It probably is not. The pilot light in a lot of power switched is a neon bulb wired across the AC mains. Those neon things sometimes flicker from the time they are new and sometimes only after some years. If you don't hear any static or sound fluctuation - rock on.

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.

Kenwood kac-6295 shuts off then turns back on at high volumes


Did you wire the speakers in series or parallel? 4 ohm speakers in parallel actually come out to equal 2 ohms wich most amps would see as a short causing protection issues. 4 ohm speakers in series equals 8 ohms which should be fine for your amp. been there : expert-tech / SAM

My RCA 32V550TYX1 turns itself off and on - flickers. The only way to stop it is to unplug the set. Any ideas?


Hello, The power light may be flashing or if you are runing with a series light bulb it may be cycling on and off continuously. There may be a chirping or clicking sound from inside the set. (Note: using too small a series light bulb load during testing for the size of the TV may also result in this condition.)
If there is a low voltage regulator or separate switching supply, it could be cycling on and off if the horizontal output, flyback, or one of its secondary loads were defective.
Does this TV have a separate low voltage regulator and/or switching power supply or is it all part of the flyback circuit? For the following, I assume it is all in one (most common).
Some simple things to try first:
Verify that the main filter capacitor is doing its job. Excessive ripple on the rectified line voltage bus can cause various forms of shutdown behavior. An easy test is to jumper across the capacitor with one of at least equal voltage rating and similar capacitance (make connections with power off!).
Use a Variac, if possible, to bring up the input voltage slowly and see if the TV works at any point without shutting down. If it does, this could be an indication of X-ray protection circuit kicking in, though this will usually latch and keep the set shut off if excessive HV were detected.

The dislay flickers SH GE90.technics .it seems to be a common fault.. can this be fixed


replace the 3 electrolytic capacitors in the power supply section near where the lead from the transformer connects to.
they're sat side by side.
you may notice only 1 might be leaky but replace all 3 for good measure.

i've had quite a few with exactly the same fault and all were cured by replacing the above.

hope this helps?

I need a hook up digram fof an optimus model 31-2025 stereo equalizer


http://support.radioshack.com/support_audio/doc48/48943.htm

Ten-Band Stereo Frequency
Equalizer (310-2025) Connections Faxback Doc. # 48943

Follow these steps to connect the equalizer to your audio system.

CAUTIONS: Use only shielded audio cable with RCA-type connectors (not
supplied). This type of cable is available at your local
RadioShack store.

Before you connect the equalizer, turn off all components in
your audio system and unplug their power cords.

Before you plug in the equalizer's power cord, complete all
connections and be sure the equalizer's POWER button is out.

1. To connect the equalizer to your receiver, connect the receiver's TAPE
OUT jacks to the equalizer's MAIN IN jacks.

Then, connect the equalizer's MAIN OUT jacks to your receiver's TAPE
IN or TAPE MONITOR jacks.

2. You can connect a tape deck to each set of tape jacks (TAPE 1 and TAPE
2) on the back of the equalizer.

To connect each tape deck, connect the equalizer's TAPE OUT jacks to
the tape deck's in jacks. Then, connect the tape deck's out jacks to
the equalizer's TAPE IN jacks.

3. Plug the equalizer's power cord into your receiver's switched power
outlet or any standard AC outlet.

WARNING: The equalizer's power cord has a polarized plug. To prevent
electric shock, do not use an extension cord or other
receptacle unless you can fully and easily insert the plug's
blades.

4. Connect the power cords of all other components.

it isnt getting enough power and its tripping the internal switch on the amp and putting it in safe mode. either your wire isnt a high enough gauge. you might need a capacitor or you need bigger wire.

Connecting the 901 series VI equalizer


hello

please make sure your receiver has a tape monitor switch on the front panel or pre-in/out sockets at the rear. only then all sources will play thru the bose equalizer. also remember if you need a 5.1 or greater setup, you will need 2 amps/receivers.

hope this helps
