This Technics RS-M280 is a stereo cassette deck with double Dolby B noise reduction,
it was first sold by Technics in 1981 with a recommended retail price of USD 0 and discontinued a year later.
The main features of the Technics RS-M280 are: 3 heads and off-tape monitoring, digital tape counter with 3 digits and memory stop, manual tape type
selection and capable of handling normal, chrome, ferro-chrome and metal tapes with automatic equalization selection, dual capstan transport.
Typical front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape eject is operated mechanically and the
cassette needs to be placed with the side to be played facing forward in the cassette well.
Level meters used on the RS-M280 are generic digital peak reading meters with multi-color indication to provide visual saturation level of tape,
peak hold for easy adjustment of optimum recording level and peak indicator for easy adjustment of optimum recording level. Full-logic transport controls used on the
RS-M280 let it respond to the slightest finger contact for fast and effortless transport function selection.
To ensure the best response from the wide variety of tapes available adjustment of, sensitivity, to optimum levels can be performed prior to recording.
The Dolby-B system reduces tape hiss on tapes recorded on the RS-M280 by as much as 10 dB at the highest frequencies. The three-head configuration of the
RS-M280 requires a Double Dolby system, one for recording and one for playback.
To make live recordings this deck has 2 microphone inputs to connect microphones with a jack connector. For undisturbed listening a jack connector for a pair of stereo
headphones is supplied. Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
All main transport commands can be issued remotely with a wired remote control.

Technics RS-M280 - Studio Collection 1981
The Ultimate Expression of Cassette Deck Technology...Technics RS-M280. The RS-M280's innovative 3-motor transport system
begins with the famous Technics planar-opposed direct drive motor. This brushless, coreless, slotless DC motor is renowned for
accuracy, durability and compact size. Using a quartz oscillator as reference, the motor's integral FG mechanism is capable of
extremely precise speed control. The result? The lowest wow and flutter ever achieved in (1981) a Technics cassette deck
- a mere 0.024% (WRMS) This Direct Drive motor is the take-up capstan while the supply capstan is belt drive. For the
RS-M280, Technics has constructed the take-up capstan to be slightly wider than the supply capstan - this difference is
then compensated for by a corresponding difference in flywheel size. In conclusion with this system speed control is
consistently accurate, and modulation noise is insignificant.
The 3-Motor System of the RS-M280 uses a different approach for motor tasks. There is one motor for high-speed
winding (fast forward and rewind) and another motor solely for driving the take-up reel during playback (or recording)
while the Direct Drive motor is used for the take-up capstan. For the 3-Head Configuration Technics uses
SX type (Sendust Extra) heads. It is manufactured by a special method that minimizes eddy currents to optimize
high frequency response. SX exhibits the very high saturation flux density needed for metal tape recording.
But it also provides superb response with all other tape formulations. With the RS-M280, it's easy to make the appropiate
bias adjustment. To test tape response, the RS-M280 is equipped with a test-tone oscillator providing 400 Hz and 8 kHz frequencies.
