Ampex Model 1461 (1968)
A four-head, auto-reversing, self-threading stereo portable with cube speakers that nest inside the case. Ampex built it to be the one machine that had it all.
Overview
The Model 1461 was a four-head stereo portable that stacked automatic threading, automatic reverse, sound-with-sound, dual capstan drive, tape monitoring, automatic tape lifters, and three-speed operation into a single cabinet 23½ by 14 by 8½ inches. Ampex's own advertising billed it as the outfit that had it all, "No brag. Just fact." The claim was aggressive, but it was unusually close to true for 1968. Audio (October 1968, p.41) ran the same "clear the air" copy as a full-page spread. That's advertising, but the feature list underneath it was real.
The clever part was the speakers. Two cube speakers, roughly six inches on a side, tuck into dedicated storage at the rear of the case, which is why the cabinet is as wide as it is. They pull out on cords for stereo listening. Ampex sold the cubes separately as the Model 415: oiled walnut with a light beige grille cloth, about three pounds each, ten-foot cord with a molded phone plug, $39.95 a pair. The 1461 itself came complete with two dynamic microphones and those two cube speakers for $429.00. Audio (April 1969, p.52) profiled the machine as a stereo tape recorder and noted the case width was dictated by that speaker-storage compartment.
The tape handling is where the 1461 earns its keep. Automatic threading means you don't hand-fumble a leader. Automatic reverse means the machine flips direction at the end of the reel without you touching it. Audio (April 1969, p.52) walked through the controls in its equipment profile, including a reverse button used to put a 20-Hz signal on the tape and a slide switch that changes equalization between the 7½ and 3¾ positions. There's also an automatic replay feature that lets a tape repeat itself indefinitely - handy for background music, less so if you forget it's on. Four deep-gap heads and dual capstan drive round out the transport, and the whole thing runs at 7½, 3¾, and 1⅞ ips.
Frequency response is quoted at 50 to 15,000 Hz ±4 dB at 7½ ips, 50 to 7,500 Hz ±4 dB at 3¾ ips, and 50 to 3,500 Hz ±6 dB at 1½ ips. Only the top speed gets close to full-range, and the slow speed is strictly for spoken word and background. Signal-to-noise is 46 dB at 7½ ips, wow and flutter 0.15%. Peak music power is 40 watts. Those figures aren't spectacular by later standards, but they're honest for a 1968 portable, and the 7½-ips performance is where the machine is meant to live.
All that automation is a lot of mechanism to keep aligned, and the dual capstan drive, while excellent for tape handling, is fussier to service than a single-capstan transport. The 761 is the easier machine to own. The 1461 is the one that does everything.
Audio (April 1969, p.52) reviewed the 1461 and, in a later issue, a reader wrote in to correct the magazine's listed price. The reviewer had it at $485 when the machine was actually $429. That's a $56 error. The 1461 was a 1968 introduction, and it sits in the Ampex consumer line alongside the 761 and the 861, all sharing the same portable-cube-speaker design language. It's not the most famous Ampex of the era, since the pro machines get the glory, but it is a fully loaded consumer reel-to-reel with genuine portability.
