350 - Line of Professional Audio Recorders

Hier werden in einem Prospekt aus 1963/64/65 die Varianten der Modelle 35x und die ähnlichen professionellen Produkte beschrieben.

Der Prospekt ist sehr ausführlich, sodaß viele gleichartige Modelle mehrfach aufgeführt und bebildert werden. Das verwirrt schon ein wenig, wenn es dann doch immer dieselben Laufwerke nur mit anderen Kopfbestückungen und anderen Bandgeschwindigkeiten sind.

Ampex demonstriert damit eine unglaubliche Vielfalt, doch eigentlich sind es alles die gleichen 351er Chassis (=transports).

601 SERIES

The Ampex 601 professional portable recorder/player gives full professional quality in recording and reproducing sound, with the utmost in convenience and portability.

Features of the 601 include:

low impedance output; instantaneous starting that accelerates to full play mode in less than one-fifth of a second; top plate that withstands exceptionally-hard use in any recording environment. The 601 Series is available with half-track, full-track, or stereo heads, in 50 or 60 cps frequencies, and with tape speeds of 3% or 7y2 ips. Saddle tan case is made of rugged Samsonite for easy portability.

300 SERIES MASTER TAPE RECORDERS

Unexcelled performance verified by continued domination of these units in the professional master recording industry. Available in single or multi-channel models (2 to 8 channels), up to three equalizations (NAB, CCIR or AME), and a variety of mountings.

Rigid unit assembly virtually eliminates flutter and wow; massive flywheel, precision capstan drive and long tape path assure no skewing. Starts and stops instantaneously. Fast/slow start switch permits "on" and "standby" capstan motor operations; provision made for remote control.

Precision head alignment assures perfect playback of multi-channel recordings with minimal phase shift between channels. Exclusive "Sel-Sync" optional feature provides switching to convert any of the heads to serve as temporary playback while others are still recording; permits sound-on-sound recording and other special effects. Available in frequencies of 50 or 60 cps, and with tape speeds of 7l/2 and 15 ips.

3200 SERIES MAGNETIC TAPE DUPLICATORS

Duplicates high quality tapes at low cost in either single or mass production runs. A full system using a double-track master and ten slave recorders can reproduce in 8 minutes the material that would require 20 hours using two standard recorders.

Anmerkung: ein ziemlich durchsichtiger und dummer Vergleich. Mit 10 Slave-Bandgeräten wären es auch nur 2 Stunden anstelle 20 Stunden.

Provides simultaneous duplication of both tracks of a double track tape. Identical quality of the duplicated material is assured once the proper duplicating level is determined.

Features include: Simultaneous control by master panel of all components; pushbutton start; full speed attained in 5 to 10 seconds. Master unit and each slave equipped with full controls. Produces 1200 hours of playback material in an 8-hour work day. Runs master tapes "backward" to eliminate need for re-winding duplicates before using.

MODEL MX-35 FOUR POSITION, TWO-CHANNEL PROFESSIONAL MIXER

Compact professional mixer for two-channel stereo and monophonic recording. Unique four-position switching facilities normally found only in studio consoles. Four mike preamps and two program amplifiers permit high level mixing and switching to feed channel A, B or both.

When both channels are fed, the source is split equally to both outputs as required for "center solo" stereo recording techniques. Six inputs: Four low-Z mike and two high level unbalanced bridging with facility to mix any four at one time. Optional, balanced bridge plug-in transformers available. Two outputs: 1 volt normal; 30 volts max., unbalanced to bridging input.

Ampex 400 Series (Mastering) and 600 Series (Professional Audio) Magnetic Tapes offer to users the world's finest recording tapes. The 400 Series gives greater dynamic range — 4 to 8db wider; superior high frequency overload characteristics; lower print through. Ampex 600 Series is engineered to meet the requirements of the most discriminating tape users. Both Series are available with DuPont Mylar or cellulose acetate base, in a variety of lengths and thicknesses.
