You can download a copy from Panasonic here.

the Technics SH-8058 is a beautiful unit, I got one myself for the past 20 years and never failed y EQuing the sound I want.

I am asuming, you got on your reciever TAPE MONITOR... well, the it is simple,

First, just forget about the TAPE on your Techincs SH 5058

Second, on your Technics LINE OUT, goes on your tape monitor LINE IN

and last; on your LINE IN, goes on your tape monitor REC OUT.

Now, choose you desire componet, and turn on your TAPE MONITOR on your reciever...

enjoy and have fun.

I have one but it is in Spanish! If want me to upload it here let me know..........

Outs to Ins in a Tape Loop on the receiver. Model numbers make it easier if we or you can find the manuals for the receiver. If only one Tape Loop, nest the tape deck into the tape loop on the equalizer.

hi,
Try this. You need 4 RCA setreo Chord for this.

1. connect the cd player out to the LINE input of Equlizer.
2. connect the Record out of equlizer to Tape's Record input.
3. connect the Play out of the Tape to the Play in of Equlizer.
4. connect the Line out of the Equlizer to the CD input of amp.


Always Select CD in the amp. And select between tape and CD in the Equlizer.
OK

the amp should have an in and out for the cassette player also,, so you would go from the Out on the receiver, to the in on the cassette,, and out of the cassette to the in on the receiver, I don't have nor can I locate that EQ , but basically,, you need to come out of the eq and back the same way you would a Cassette player,,

I see an EQ and a Receiver with NO Tape Loops or external audio sources mentioned.

Are you implying this used to be hooked up and working? Or are you asking how to integrate the EQ NOW after a move?

Normally the receiver would have a defeatable external loop for Tape recording. THAT is where the EQ or any other processor would go.

The following is mostly boilerplate for receivers WITH a tape loop. You need to understand what will and will not work even if you could attach the EQ.

--- Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.

The connections themselves are fairly simple but it pays to understand what happens in the loop.

In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).

Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.

The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.

EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.

In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? The rest would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that's the way it is. Nature of the digital beast. --

If you wanted to Equalize a single external analog source you would have to connect the EQ Line output to either of the two analog inputs ("DVD" or "Video" in your case) and connect your external source to the Playback jacks on the EQ.

I would want to know if it's just an indiction problem or an actual notch.

Let's prove the signal is pure going to the EQ.

Tune between FM stations with no automatic muting on your receiver so you can hear a loud hiss. Monitor the EQ display. There should be a lot of energy across the bands. If you see the notch swap the inputs to the EQ to prove it's in the EQ. Otherwise the signal is being affected upstream.

Let's prove there's no audible notch in the bandwidth. This is the fun part.

Set your system to just play Stereo with the FM hiss and if there is a Stereo Direct setting that bypasses internal circuitry, engage it. Adjust the EQ for equal level and flat response on both channels.

Disconnect the two front speakers. Wire just one front speaker across just the Positive leads of the Left and Right amplifiers. This is not dangerous. (**)

** Back in the day we used this kind of wiring (with some proper resistance and circuitry to prevent interaction between the front channel speakers) to extract ambience (difference) information from plain stereo to drive a speaker at the rear of the room. Adjustment was done by selecting MONO and turning the Balance control for Minimum output, then going back to Stereo for listening. Ah, the old days.

What this does is make the speaker play only what is DIFFERENT between the channels. If the source is truly MONO as it should be there will be a minimal output presented to the speaker. In an ideal world a true mono signal fed to both channels in this manner would result in total silence. There will always be some difference in the real world.

You can prove the accuracy and fullness of the EQ signal by adjusting one channel of the EQ to be different and as you do the sound should start to rise as the Delta increases. Returning the controls to flat and equal should provide minimal output. If there is a solid audible difference in the treble range the EQ might actually be showing the 6.3khz deficiency accurately. To see if it's at 6.3khz adjust the LEFT channel downward to match the display of the RIGHT and the difference program material should become very low as heard from the speaker. That would indicate a true deficiency in the LEFT channel.

Fixing it might not be possible but you might be able to use the EQ to offset it.

This is boilerplate I wrote a long time ago for general eq or sound processors. Without know to what you are connecting, well, read on...

Okay, back to the hook-up: Receiver Tape- or VCR Out to the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-In; Receiver Tape- or VCR In from the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-Out.

If you actually want to use an analog recording deck you could place it within the typical Equalizer's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks.

According to Panasonic the manual is only available for purchase (paper/CD-ROM) 1-800-332-5368

Hi,
Before we can help you we need as much information as possible about what happened the last time you used the equalizer, have you had any storms lately? when you last turned the equalizer on did you hear it go bang?
Please provide as much information as possible.

An equaliser is, put simply, a more complex tone control, giving you the ability to cut or boost more specific frequencies than a tone knob, or bass & treble controls.

It comes in handy for tweaking the sound from your hi-fi to just the way you like it. But beware, as it can make your hi-fi produce sounds that are so bass or treble heavy, that you can damage your speakers if you're not careful.

Adding another compnent into the chain (like a graphic EQ) can add a little background noise but this Technics EQ is a pretty quiet one & you probably won't notice the noise apart from when there's no music playing & you've got the amp turned up high.
