Description
The Ampex ATR-700 was made in Japan by Teac/Tascam to Ampex’s design specifications. The inner workings are in fact those of a Teac A-7300 . Unlike the Teac, however, the ATR-700’s input/output connections are of the professional XLR type rather than domestic Hi-Fi RCA plugs.
Two speed options were available, 3¾ and 7½ ips or 7½ and 15 ips.
The standard ATR-700 was configured for half-track stereo operation and had three heads but a space was reserved for a fourth quarter-track reproduce head as an optional extra. Other configurations included full track, two track and quarter track in either mono or stereo. The record heads could be switched to sync/reproduce for synchro recording via small switches on top of the head block. Edit button disables the take up motor for dumping unwanted tape from the supply reel, while the tape lifters are retracted for manual cueing in stop mode.
Other features included an adjustable pitch control (±5 %), IC-logic control for error-free operation, motion sensing logic permitting change from fast forward or rewind mode to reproduce mode smoothly without tape spillage or damage, positive tape control from direct drive dc-servo capstan motor, vertical or horizontal operation, two-position reel hub size selector for small or large reels and a rewind-stop memory switch.
The ATR-700 sold in the USA for around $3000, with six different versions available.
