I'm installing a pyramid tape deck and there are

You'll need to contact a local car audio professional or Pyramid customer support directly here:

This has nothing to do with tape decks.

The deck should reset if the power cord is unpluged. On power up the deck should return to normal. If it does not then the condition that caused it could still be present or is now set up wrong. It is quite possible that the mode switch is in the wrong position and would need to be set up correctly. Unless you have done this before, you will probably need the service manual, as most VCR's are not set up in the eject mode!

DO NOT , UNPLUG THE POWER CHORD, DO ONE THING SWITCH ON THE VTR AND THEN HAVE AN ALL PIN .. THEN RESET THE MACHINE ... WITH THAT PIN .. AND THEN PRESS EJECT ... YOUR TAPE WILL COME OUT ..

I only know of one way to do this and here it is:

1. Plug your tape deck's output (cassette or R2R) into the EQ's "Line In".
2. Plug the EQ's "Line Out" into the Receiver's "Tape 1 Input".
3. Now plug the Receivers "Tape 1 Output" into the Tape Player's "Line In".
4. You have now made an "FX loop" for the Tape Deck. Now you just have to put the Tape Deck on "Tape Monitor".....put the Receiver on "FM"..... and turn on your favorite FM station and you will hear the FM Receiver THROUGH the tape deck's "Monitor Send" AND the EQ.............set EQ to taste....... and BINGO.......DONE!

-try a power cycle
*remove battery and disconnect from power cord
*i would also suggest to check the tapes if they're clean
*try to clean the tape head inside the tape deck(tape head: the one that reads the tape)
-try using a soft and dry Q-tip to clean the metal parts inside the tape deck(dont use or apply any liquid solutions. just a plain soft dry Q-tip.

If the hum is audible without monitoring a tape playback it has nothing to do with the oxide formulation or any aspect of the media.

Determine the conditions present whenever the hum is present:

Player just turned ON?
Tape deck Playing or Paused?
Tape deck Recording or Paused?
"Tape" selected at the receiver?
Any source selected?

What switch are you referring to? You could have a floating ground or shield through a Tape Monitor or other control. Audio cables between the Deck and the receiver could be faulty or require reseating with a twisting motiuon to remove oxide build-up.

Hum can enter any unshielded cable running near any motor, magnetic field or some light sources. Sometimes simply reversing the polarity of an AC power cord will cure it.

Belts shot? Open it up and look to see if they're slipping, which would make the machine stop tape motion.

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.
