Pioneer RT-2022

A rare big one made of two separate units : RTU-11 tape transport and TAU-11 rec/play amplifier.

The 2022 is, previsibly, the 2-track / 2-channel master recorder, the 2044 is the 4-track / 4-channel versions, with two TAU-11.

Behind the glass lid of the TAU-11 are a 2-step / 4-variable test tone generator, a 5-step EQ setting navigating between the NAB and IEC standards, and a fixed/variable bias setting pot ; mic/line mixing is possible, plus the usual "echo" or "tracking" functions.
A MIC attenuator switch is provided alongwith full tape/source montoring and a rec/play/sync selector for each channel.

The solenoid-operated RTU-11 has its head-block easily exchangeable the JT-2044T 4-track head-block and sports a wired remote-control socket as well. The lever below the left reel is for "pause".
The chassis is made of several big diecast structures bolted together, too.

Unlike Denon which relied on Teac chassis & motors for its DH-610 and DH-710 open-reel recorders, the Pioneer RTs were all in-house developments.
