The 4400 Reprt monitor offered four tape speeds (7½, 3¾, 1 and 15/16 ips), three heads and a 5" reel
capacity plus a clear cover to keep the dust and dirt away from the tapes. This machine was very
reminiscent of the Nagra 4.
Recording options were multiple; Independent 'rec I' & 'rec II' inputs with a master control; ability to record
in stereo, or Chan I/Chan II independently and the ability to be used for film soundtracks, (one channel
serving to carry sync tone).
Unlike the Nagra (which only had one meter), the Report Monitor 4400 boasted two large, round backlit
VU meters; one each for channel I and channel 2. Meter 2 doubled as a volt meter to monitor battery
strength. (five "D" cells were used).
