Wireless IR Remote Receiver for the Nakamichi ST-7 (ST-70, ST-7E) AM/FM Tuner (Gen3)

Instructions for older Gen1 and Gen2 units

 

 

This unit is very similar to my Nak Tape Deck IR Remote Receiver, but, the interface needed to be changed to interface to the ST-7's DIN-7 remote jack. This remote allows the following functions to be controlled remotely. Memory 1-8, Shift9-16, Seek up, Seek down and AM/FM. The Memory 1-8 buttons are mapped to the remotes number buttons "1" - "8", Shift9-16 is mapped to the "0" number button. Pressing it the first time will activate Shift and pressing it again will deactivate it. Seek up and down are mapped to Channel Up and Down. AM/FM is mapped to TV/Video, pressing it the first time switches to AM, pressing it again will switch to FM.

The unit is about 2.6" by 2.6" by 1.1" tall.

The back of the unit has a single cable that connects to the remote jack on the Nakamichi ST-7. Power for the receiver is drawn from the ST-7, but, the tuner needs to be opened and a resistor jumpered over with a special wire with hooks on the ends. This is completely reverseable.

The power LED will light when the unit is powered. When the unit receives an IR signal that matches the device code selected then the LED will blink off for a half second. This LED will blink off even if the button is not supported. This aids in verifying that the remote is configured properly.

Device Select jumpers - The two jumpers select the Sony IR device code that the unit response to. Any Universal Remote configured for Sony TV or VCR will work. It doesn't need to be the one I supply with the unit.

The IR Wireless Remote Receiver for the Nakamichi ST-7 and a 3 in 1 Universal Remote is $60. Shipping within the US is $7. Shipping anywhere else in the world is $12. I sometimes sell on eBay. Just search for "Nakamichi ST-7 Remote" my auction should be the only hit. The price is about $5 highier on eBay because of the fees they charge.

I also work on the Nakamichi ST-7. So if your preset memories don't stay or the display is blank I can fix it. Don't contact me regarding any parts like knobs and buttons. I don't have any.
