Special features

ISO-LOOP tape handling.
Mechanical counter which is only correct (1%) at highest speed (38cm / 15 /S).
Solenoids.
Headblock design allows for quick swap of the entire tape path and heads. The RS-1500 comes with the RP-2422 4 track headblock (YEN 38,000) w 2 track playback. But the RP-2224 2 track headblock (YEN 38,000) w 4 track playback can be swapped in its place. Head blocks retain their tape handling properties as to azimuth and so on. Also usable are RP-2224SX (YEN 58,000) and RP-2422SX (YEN 58,000).
Headphone monitoring.
Timer function.
Optional cable remote RP-9690 (YEN 13,000).
Optional infrared remote RP-070 consisting of RP-070T transmitter and RP-070R Receiver (YEN 30,000).
Optional Soft dust cover, white thin vinyl with black Technics logo in the middle of the front. The logo is either large or small preceeded by a National brand symbol.
Optional Hard acrylic dust cover RP-9110.
Optional Road case RP-9100 (YEN 35,000).
Optional 19in rack ear RP-9130 (YEN 2,000).
Optional Battery operation using car battery interconnect RP-086 (YEN 30,000) or Battery pack RP-099 (YEN 30,000).
Optional Take up reel RP-10A.
Optional veneered rosewood side panels RP-9120 (YEN 5,000).

Comments

Reels including 18cm do not exceed the sides or top of the deck when mounted.
Isolated Loop Tape Transport.
Quartz Direct Drive Capstan motor and twin Direct Drive Reel motors controlling tape tension and speed during the tape run.
The RS-1800 features three tape speeds 19/38/76 cm/sec.
Microcomputer Circuit offers advanced functions such as Time Counter to display tape position by time, Auto Locator to pinpoint desired tape portions and Speed Deviation Indicator which monitors tape speed during running.
Auto Bias/Equalizer automatically sets bias current and recording equalization for the type of tape being used.
