How do I attach and play a technics record deck to a technics DV250 amplifyer?

Hi, I sent you a link to the Technics DV290, which is more similar to DV280
I hope you find it useful

If you plugged it into the aux or vcr input and have no sound, you probably need a phono amplifier first. Signals from turntable are very low in comparison to other sources and need to be boosted up to normal levels first.

The signal output from the turntable is very low and needs a special input which most modern sound systems no longer have.
You will need to connect your turntable to a preamplifier.
The output from this preamplifier then goes to the auxiliary input ("AUX") of your sound system.
A good starting page to look around for a turntable preamplifier is here:

Good luck!

The answer is simple if you want to listen to mp3 on your system and you purchased dv290 dvd changer you also need dv290 sound processor as they were coded - for example you have dv250 system with dv250 chager and sound processor you are only going to be able to see dvds and cds if you swap your changer to dv290 (plays mp3, audio ,wma and dvds) you also need to purchase dv290 sound processor as well - no need to change your amplifier or tape deck (the ribbon on the tape deck will be compatibile)
the lower end units were incompatibile with higher spec changers same when it comes to EH series if you have eh780 sound processor you are only going to be able to plug 780 changer or lower 760 770 etc... but 790 will not work with it unless you get 790 sound proc

Is that what you are finding?

I assume you want to record from tape to computer and monitor the recordings later.
Simple three steps.
1) Connect the tape deck line out ( or labeled PLAY ) to any one of the inputs like Aux / Tuner using an 2RCA connector.
2) Connect Rec out from the SUV' to line input of your PC ( blue socket ) sound card.
3) To monitor your PC sound after recording on to Hard Disc , connect a cable between the PC sound out ( green socket ) and the the SUV Tape monitor IN ( sometimes labeled PLAY ) Now comes the tricky part.When you want to record on to your PC put the source switch on the SUV to where you have connected the Tape deck ( Aux / Tuner ). On the SUV keep the Tape Monitor switch to source ( released position ). After having done the recording to monitor and hear the Hard Disk playback turn on the Tape Monitor switch ( dipress it ). The pressing of the Tape switch on the SUV lets you toggle between the source and recording - In your case Tape deck and PC

The manuals for these are on paper not electronic files. Is there are particular problem you are trying to solve?

As a work-around, you could "protect" your tapes by removing the little snap-off tab in the top edge (left as viewing the side you want to play). That way the hardware can't possibly go into Record Mode and ruin a pre-recorded tape.

If you can see it, there is probably a little spring-loaded sensor arm inside the cassette well that 'feels' for the tab's presence. Is it free-moving and undamaged?

Each unit (the EQ and the Processor) should have left/right in/out rca jacks as well as L/R tape in/outs. The EQ or processor use the receiver's tape loop and then provide a tape loop to replace the one they've used on the receiver.

You plug the first unit (let's say the Sound Processor into your receiver/amp as if it were a tape deck (Processor's outs connect to reciever's tape ins (play) while the Processor's ins connect to the receiver's tape outs (record).

Then you chain the EQ off the Processor in the same way (EQ outs connect to Processor's tape ins (play) and EQ ins connect to the Processor's tape outs (record).

Last you connect the tape deck to the EQ as follows. Tape deck outs connect to EQ's tape ins (play) and the tape deck ins connect to the EQ's outs (record).

This will put both the Sound Processor and the EQ in the receiver's tape loop. In order to have all the receiver's source signals routed through them you may have to engage a Tape Monitor switch or button somwhere on your amp which will route the tape loop to your speakers.

keep an eye out on ebay.
