Description

The stereo cassette deck which carries cassette erecting loading and oil dumping ejection.

The cassette has adopted as a tape wearing mechanism the cassette erecting loading system set to a perpendicular erecting. Wearing of a tape is easy and also it has become the design in which the merit of front operation which can face squarely eye music were written to the run state of a tape, residual quantity, and a label was employed efficiently.
adoption s Moreover, the oil dumping mechanism original with an Aiwa is in the ejection mechanism.

Three steps of bias, three steps of recording equalizers, and a 2 steps of playback equalizer change are adopted as a tape selector.
Moreover, the correspondence nature to various tapes is also increasing because bias and an equalizer can switch independently.

If an option timer is connected and the deck is set, absence recording, alarm clock playback, etc. can make the time of choice start a deck. Moreover, in a standby state, since the pinch roller and the capstan are separated, there is no fear of changing a pinch roller.

The change-over switch of line-in, and a microphone and a DIN input is carried.
Thereby, NS ratio is improving by about 10dB compared with the conventional system which lowers the level of an incoming signal by resistance and is again amplified with microphone amplifier at the time of the recording from line-in.

The quick review cue function is carried and rewinding and fast forward can be performed with recording or a playback state.

The volume only for playback is carried apart from recording volume.
