SONY TC-R7-2 (1977) - To be heard to be believed

Sony's hi-fi components line has to be heard to be believed. With the lowest wow and flutter of any deck Sony ever built, a duo of tape recorders were introduced in 1977. These were the Japanese market SONY TC-R6 and SONY TC-R7-2. The same models were available worldwide as SONY TC-765 and SONY TC-766-2. They both share the same construction but while the R6 is a 4 Track Stereo Recorder running at 9.5 and 19 cm/s the R7-2 is a 2 Track Stereo Recorder running at 19 and 38 cm/s with an additional 4 Track head for playback. The SONY TC-R7-2 achieves an incredible wow and flutter of 0.018% (WRMS) at 38 cm/s and 0.04% (WRMS) at 19 cm/s. This is achieved via a Closed Loop Dual Capstan Tape Drive System. One capstan extends from the motor shaft itself, eliminating intervening gears that can hamper speed accuracy. The other tape drive capstan connects through an extremely steady belt-drive inertia wheel. For a "mirror image" of the original signal, Sony's exclusive Phase Compensator Circuit comes closest achieving this by rectifying phase distortion and producing sound qualitty virtually identical to the original source. 

Illuminated, calibrated and ultra-clear for best monitoring possible, Sony's Professional Studio Standard VU meters are identical in size, shape, color and sensitivity to those on professional consoles. Because of Sony's outstanding Ferrite & Ferrite Heads, plus the remarkably precise fabrication and alignment of the head gap, recordings retain exact positioning of signal throughout the stereo field. The "location" of individual sounds won't wander. There's no annoying phase shift. More professional features include direct-coupled playback FET amplifier, flashing Standby Signal, Punch-in Record and solenoid-operated Logic-Controlled Transport Functions to let you move instantly to and from any mode without stopping. Standard equipment: RM-30 full-function remote control unit with record mute and hinged head cover.
