Microcassette Compact Cassette Recorders
Record/ Playback System
LA4168M record/ playback system microcassette compact cassette recorders. LA4168M extremely high-functionality that includes motor control governor circuit, voice sensor circuit that detects sounds turns motor off, power switch control circuit that receives electrical signal from photosensor turns function blocks off, circuit that increases speed motor during playback.
Features
Includes voice switch that turn governor off. Includes power switch circuit that turn function blocks from photosensor signal. During record, automatically turn governor according microphone input level, furthermore, governor level continuously adjusted from external control knob. (The control used volume adjustment during playback.) Continuously variable microphone monitor level. Includes drive that lights only when governor record mode.
Functions
Microphone playback preamplifiers Record amplifier Power amplifier (BTL, Automatic stop circuit (power switch) Governor circuit Motor speed high-speed switching circuit Microphone power supply drive circuit Voice sensor circuit
