Can you fry an EQ?

I recently bought a nice vintage Technics system from a local guy on craigslist. Technics SU-V9 Amp plus Technics tuner, casette deck and Equalizer. Huge Sansui speakers with 15" woofers. It's in my garage and really rocks. When I tested it at his house and when I first brought it home, I swear that the EQ was functioning properly meaning, frequencies actually adjusted when levers were moved. Now, although the red lights are on the levers and the spectrum analyzer is keeping the beat with the music, I can't get the sound to change when I move the levers on the equalizer. Possible I don't have all of the switches in the right place but just wondering, is it possible to actually blow up something in an equalizer that will make its ability to actually adjust the frequencies stop working? Thanks!

You didn't damage it. You probably need to cut it into the circuit with the tape monitor switch, or whatever place you connected it. Or maybe it has an in-out switch itself.
 
I would guess you have it connected wrong. Pretend it is a tape deck and hook it up into Tape 1. Then to use it, make sure Tape 1 is turned on
 
Thanks. I'll mess around with it this weekend. Was quite pleased to learn that my neighbor, who lives across the street, could hear it in her house while she was taking a shower last Saturday and I only had it turned up to about 4...
 
what they said. use the tape monitor loop for your eq and all should be good. select tape 1 or 2 on front panel if there is 2.
 
Really It Pleases You to Know You Are Disturbing Your Neighbors? Really?

Wow glad we aren't neighbors. I work rotating shift, and therefore work nights. I think we would be having a discussion about this. Sure its not against the law, but it really doesn't show much common courtesy. Why force your music onto others? I have a car stereo with over 1.5 kilowatts in it.Yes its loud, yes I can vibrate windows. But its for me, and I turn it up when on the highway, not when driving through residential areas.

Nice show of class.

BTW you have the EQ hooked up wrong. It should be in a tape loop, and engaged through that function. If you have an amp/pre amp combo you can install it between the two units. But then its active all the time, the tape loop is a better place for it. The EQ itself may have a bypass switch on it that defeats the controls. Look at that too.

inputs and buttons

Sounds like you have the tape monitor switch ON on the EQ and no loop back from a tape. OR, the input selector on the EQ is set wrong, OR, etc...


I have a couple TEAC EQs that have too many inputs and outputs and buttons and get all mixed up once in a while and I've been doing this for 30+ years.

Sort of like using computers with Windows...keep clicking things until you get what you want.

well, it plays loud anyway.
Must be a trend as i have read in a few posts lately how they are so happy it blows out windows. Not saying that is wrong(unless you are pissing off the neighbors) as I am known to crank her up frequently when I am roaming, just a trend I have seen.

Good thing you didn't turn it up to 11.:D
 
I'm sure you could fry it, but I bet it'd taste better broiled, maybe with drawn butter on the side... :D

(ducking!)

Yup, and it's probably about maxed out on clean power around 5. :)

Very seldom can one turn a receiver much past the 1/2 way point and still be getting clean sound. I'm sure there are some where you can, but those (relative) few I've ever played will are pretty much "all in" by about 1/2 way up the dial.

Of course, it can vary quite a lot with the source output level too.

Back to the main point though, yeah, does sound like you have the EQ in bypass/defeat mode or maybe have the tape loop disengaged.
