1.1 MX-55 Series Tape Recorders
The MX-55 Series of Tape Recorders are built on die-cast aluminum
alloy deck plates and side frames for maximum ruggedness and
mechanical stability.
All machines in the series will accept any size reel from a 5" EIA reel
to an 11.8" DIN hub. Different size reels can be used for Supply and
Take-up.
The front panel pitch control utilizes a unique rotary encoder to pro-
vide ±20% variable speed range in 0.01 % increments. The capstan
motor speed can also be controlled by an external source of 9600
Hz (nominal) square waves for easy interface with a synchronizer or
similar controller. The speed range under external control is
+ 100%, -50%.
An optional Voice Edit mode PCB allows listening at twice normal
play speed without pitch shift for easy editing of lecture and inter-
view work or for transcription.
