TRIO KX-3000
¥ 42,000 (released in 1975)
Commentary
Front loading type stereo cassette deck.
Equipped with a 2-stage bias / 3-stage equalizer switching function.
The bias switch is a two step switch between normal and chrome, and the equalizer switch is a three step switch with an extra position in addition to normal and chrome.
Equipped with ALC (auto-level control) function.
If ALC is turned ON during recording, sound with little distortion can be recorded even when a large input is momentarily input.
The mechanism uses an ultra-precision finished capstan with a roundness of 0.1 μ and achieves stable rotation.
A hard permalloy head is used for the read / write head.
Equipped with a full auto shut-off mechanism, there is no burden on the tape or mechanism when the tape is finished running.
KX 3000 is the same size as Amp KA 3300 and Tuner KT 3300.
