This is a component of the Technics 808 stereo audio system, it’s only function is to allow for remote control (Infra-red) of the other system components:
* RS-M45 (Single cassette deck)
* ST-K808 (FM/AM Tuner & System audio preamplifier)
* SL-Q33 (Turntable)
I do have the first two components listed above BUT the SL-Q33 has already found a new home.
This component beautifully matches the other components to make a very slim, modern looking Technics system
Although all of these Technics components work well together, each can be run separately on “other” systems, Technics or otherwise.

The SH-R808 (remote controller) does NOT control the SE-A808 power amplifier, there is no need because all control of the power amplifier takes place at the preamplifier (ST-K808)
THERE ARE NO ISSUES WITH THIS COMPONENT but I have spent quite some time investigating this remote control system, it is both interesting and designed a little strangely as well so it is very important to read my notes below …

Technics Remote Control System
Model: SH-R808
Includes the ORIGINAL Technics IR handheld remote controller (Technics calls this the transmitter)
Multi-voltage AC input capable, 100 – 110 – 220 & 240V AC
Currently set to 240V
Minimal front panel controls: On, Volume Up & Down buttons
Remote operating range: 7 metres
Dimensions (W x H x D): 430mm x 75mm x 270mm

Weight: 4 kg

SUPPLIED ITEMS:
Technics SH-R808 component (as described here and pictured)
Technics SH-R808 remote controller (transmitter)
NOTE: No batteries will be supplied due to restrictions by Australia Post on the transport of equipment containing batteries. Uses 2x AA Alkaline batteries (very commonly available)
2x Control signal patch cables for other equipment

NOTE: Like the other Technics system components I am offering, this equipment uses a 2 pin parallel plug. I am not offering an adaptor with this unit because I just plugged this into the rear of the preamplifier unit so that the two units are under the same power control. If for some reason you DO need an adaptor (2 pin to 3 pin but unearthed) then I can most likely find another for you and supply that – just ask.

FUNCTIONS:
Rear panel has 3x 8 pin DIN sockets, one each for the SL-Q33 Turntable, ST-K808 AM-FM Tuner & Preamplifier and the RS-M45 Cassette Deck.
Each of these are connected using one of the control cables to the component under IR control.
The rear panel also has one set of audio inputs and outputs (RCA connectors) and these are only for the audio level control between the ST-K808 and the SE-A808 Power Amplifier.

There is more to this remote control equipment than meets the eye, please read about my observations of this equipment below!
It is like this …
The SH-R808 Remote controller has two separate sections, one is to provide control signals to the other system components and the other section ONLY controls the system audio.
AUDIO
The audio signal section of this component operates separately to the control system and the input/output for both audio channels is accessible via standard RCA sockets at the rear. ANY external equipment audio level can be controlled by this system.
Now this means that this
