Commentary
A two motor cassette deck equipped with dbx.
For recording digital sources such as CDs, it is equipped with dbx, which has a noise reduction effect of 30 dB or more.
In addition, it is designed for 3 nr with Dolby B and CNR.
The AX amorphous head made of amorphous alloy is used for the recording / reproducing head, thereby realizing excellent high-frequency characteristics and distortion characteristics.
The mechanism uses a 2-motor computer logic system to achieve stable tape travel and reliable operation.
Equipped with an auto input selector and an auto tape selector.
Equipped with a timer standby mechanism.
