Graphic equalizer I have connected a graphic equalizer to my Onkyo TX-8222. The visual indicators on the equalizer work but there is no change in the sound when adjusting the equalizer. WhY?

The TX 8555 can drive the speakers directly but if you want to use the equalizer then you need to add an amplifier to the system so that you can feed the pre-amp connections from the TX8555 through the equalizer and then into the amplifier to drive the speakers. This is because the TX 8555 doesn't have a loop back function for monitoring recordings.

Some commonlpace questions, ok, you don't need an expert for that:
Did you try another electric outlet?
Did you check plug, cable and connections to your receiver?
Did you try pressing on - off several times?

Hi Daniel you can connect your Eq to the Tape2 input/output, if you need further assistance please give our Product Support Team a call at 800-229-1687 they are available 24/7, Thanks, JT

On the rear panel there are two jack socket marked: Left and Right Insert.
These are connected to the graphic equalizer using two insert cables, one for each channel ( L & R). The cables have a stereo 6.35mm jack plug which plugs into the mixer, the cable splits into two mono jack plugs marked tip (or send) and ring (or return). The send (tip) connects to the input of the graphic equalizer and the return (ring) connects to the output of the graphic equalizer. How it works: The stereo jack interrupts the signal in the mixer and sends it to the equalizer, the equalizer processes the signal then sends it back to the mixer. Typical cable is shown below. If the equalizer has a different type of socket, phono for example you will need jack to phono adapters or insert cables with suitable plugs. Hope this helps.

There should be the connections from the turntable connected to the input of the equalizer then the output of the equalizer to an amp
Some turntables require a preamp so refer to your turntable manual.
(Some equalizers act as a preamp) You wont hurt it by trying it.

Depending on the amplifier, it might not provide enough power (in Watts) to the speakers. If the speakers require more power, it won't be as loud.

Never use maximum volume for troubleshooting. The errant switch or control that you eventually find and flip will suddenly release the amp's full power and you'll destroy your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Look for a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

sure... externally from speaker leads.

tou may want to hook this to speaker select switch

sounds like a reception problem. Is there a visual meter for the reception? Check your antenna.
