Providing professional features and quality at a domestic price, the A 4070G was a three motor, tape deck with an equivalent of six heads (combined record/erase and two playback) giving it the ability to record and playback in both directions. Servo controls meant that remote control was possible if one purchased the optional remote unit. An interesting feature was a combined pause control/fade-out slide control for recording. By slowly pushing up this slide control one could fade the input source and then pause the tape during recording, reversing the procedure if required to fade in and begin recording another track! Additional images and a circuit diagram for this recorder are supplied on the Get Reel Contemporary Classics CD-ROM.
