Audio Recorder Reproducer A807

Studer A807 is a Professional Analogue Tape Recorder, introduced in 1986. It was the last tape recorder to be produced by Studer (up to year 2000). This recorder is highly versatile and configurable for different applications. It was a work horse for many radio stations all over the world. It is a robust machine working with a very precise control of the tape movement.  It uses magnetic tape with ¼” of width and accepts reels of tape  with diameters up to 10 ¼”; conventional reels, NAB reels and cinema reels.

Tape speeds are available from 3.75/7.5/15 and 30 ips. Variable tape speed is available (module).

There are monophonic, stereo and four channel versions.

Most of the more relevant control parameters of the recorder are stored in a non-volatile memory. Some DC control voltages are converted to digital and digital words are stored in the memory.

Remote control is available through serial and parallel digital interfaces.

Recorder may be configured  for rack mounting, mobile cart and other options.

The recorder may have or have not VU meters. For radio broadcast studios, units without VU meters are normally preferred. These machines are working in a calibrated mode (e.g. 6 dBu nominal level for 514 nW/m tape flux), without external gain control. For general recording applications, units may have VU meters and potentiometers for adjusting record and play gains. A807 Tape Recorders with VU meters are more expensive and desired by collectors.

VU meters and controllers may be placed in the main unit or into a bridge above the machine..

Frequency response of the recorder is 30 Hz to 20 kHz for tape speed of 30 ips.

The SNR ranges from 50 dB to 70 dB dependent on the number of tracks and tape speeds.

All units are equipped with Dolby HX-PRO.

Weight of the recorder is about 30 kg (dependent on version).

Power consumption is 100 W (in idle mode) or 200 W (during recording).
