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.
