Legendary “Isolated Loop" 3-Motor Direct-Drive Open-Reel Tape Deck with Quartz-Synthesizer Pitch Control. The RS-1800 has basically the same high-level professional performance capability as the other models of this series, but with several additional features to enhance the "Isolated Loop" construction. Foremost of these perhaps is the quartz synthesizer pitch control with digital display of rated speed and actual selected deviation. The digital display also shows, using microcomputer technology, elapsed time in hours, minutes, seconds. The 76 cm/s tape speed means that fidelity is better than ever. Bias and equalization can be adjusted automatically, or manually if desired. Microcomputer "Memory" function (of time setting) for automatic position location convenience. Other features: "Auto-Play", "Auto-Repeat" and SX head assembly. Separate amplifier unit for mounting flexibility. Transport unit weight: 36kg, amplifier unit: 16.6kg.
FEATURES: 4-HEAD SYSTEM (3 SX for 2-track rec, 2-track repro, 4-track repro); 1 double-gap ferrit for erasing. OPTIONAL HEAD ASSEMBLY: RP-2422 (2-channel, 4-track rec/repro & 2-track repro); RP-2224 (2-channel, 2-track rec/repro & 4-track repro). CAPSTAN DRIVE: Quartz-phase-locked control DC brushless servo direct-drive motor. REEL DRIVE: 2 tape tension controlled DC brushless direct-drive motor. ERASE DEPTH: >70 dB/ 1 kHz. OPERATING LEVEL (OVU): 185 nWb/m.
