Pioneer RT-1011L


Pioneer's engineering policy assures reliable operation and quality performance from the new RT-1011L 4-track stereo tape deck.

A thick 5mm front suspension panel and solid, die-cast framework provide extra strength margin for the 10-1/2 inch reel load and stable tape transport system.

Wow and flutter is reduced by the precision 4/8-pole hysteresis synchronous capstan drive motor, coupled with a "tuned" 100mm flywheel and high-precision 0.2u error capstan. A high-torque 6-pole induction motor ensures optimum tape tension.

The 2-channel 4-track recording and playback heads are hyperbolic for superb tonal quality, ideal head-to-tape contact, and exhibit excellent electromagnetic characteristics. All three heads are arranged in a short tape path to enhance stability.

And Pioneer's long experience in tape deck design means top versatility. The RT-1011L includes switched circuits for 2-step bias and 2-step equalization for balanced recordings with any tape.

Advanced design and electronics also means wide dynamic range from the mic / line recording amplifier and offers easy mic / line mixing, solenoid-operated direct-changeable function buttons, auto record facility for use with pre-set timer, large level meters, lockable pause, and more.

bought one today at a yard sale for $50, got her home and opened her up and what a dirty girl. Cleaned and lubed put back together and BOOM, up and running. I'm as happy as a clam. I can't believe the performance of this unit compared to my single motor decks, I do believe I'm in love. Hope I don't go broke with audio gear, lol.

If I can't rate it high, I won't own it. Maintenance of this unit is straight forward. Belts are very simple to install, not like some decks that require a major take-down. Original pinch roller can be brought back to life with Rubber Nenue. Bought this unit at an estate sale with no regrets.

Well pleased with my unit. A worthy addition with my RT 1050.
