Use the white plugs for the left channel and red plugs for the right channel. • Systems Remote Control (Refer to page 14) A wired remote control box can be connected to this unit.

AUTO TAPE SELECT FEATURE This Stereo Cassette Deck contains an Auto Tape Select feature which automatically selects the optimum bias and equalization for the tape in use. This is accomplished by detection of tape type detection holes in the cassette housing. • If a tape without tape type detection holes is used, the deck will automatically adjust itself for normal tapes. PLAYBACK • Switch on your amplifier or receiver. • Set the TAPE MONITOR switch on your amplifier or receiver to the TAPE position.
AUTO TUNING Though tapes may be of the same type, tapes of different manufacturers and even tapes of the same manufacturer may have slightly different recording characteristics. The auto tuning system is a function which automatically sets the optimum recording characteristics to take maximum advantage of the performance of individual tapes. Set the cassette tape to be tuned into the cassette box. Set the Dolby NR switch for the position to be used for recording. Caution: 1.
PROPER RECORDING LEVEL A too high recording level can saturate the tape and cause distortion. On the other hand, if the recording levels are set too low, soft passages will be marked by residual noise. Proper recording level is the single most important factor for making well balanced recordings.
