Technics RS-646DS


Crafted on a slightly larger scale than the RS-686DS, the RS-646DS is also a completely portable, completely component quality stereo cassette deck.

Look at the large Level Meters, Dolby NR Switch, Push-Lock Input Level Controls. It's all there, up front where you can use it.

With this deck you can make professional quality recordings in the field and take them home for high fidelity listening pleasure.

Separate Bias and Equalization Controls let you get all the sound quality today's recording tapes were designed to give. And the Limiter Switch and Meter Light help you get the best recordings in even the worst conditions.

The Silent-Stop Mechanism that stops the tape without annoying switch noise may not be necessary in most recording situations. But when you do need it it's there, another example of the professional attitude that the RS-646DS symbolizes.

External controls are a reflection of internal circuitry and you can depend on the outstanding circuit design used in the RS646DS.

In the amplifier circuit Technics uses IC's to cut noise and distortion and raise linearity. The result can be heard in the outstanding, realistic recordings you'll get from this completely portable stereo cassette deck from Technics.
