Otari MX-5050. B II.2
direct drive motors, no belts in this machine.a built in test and cue-tone oscillator.Front adjustable record bias, equalization + level controls.XLR type connectors for microphones L + R.Adjustable output control.(2) VU meters with peak indicator.LED counter showing, hours minutes and seconds.Memory stop for automatically stopping the tape
Among the many professional features of the MX-5050 series are:
while in the rewind mode at a desired position.All components of the tape transport are mounted on a rigid
aluminum frame for stability.
The transport design incorporates two 6-pole induction motors
for the reel-motors and a 3 speed dc servo-motor for the capstan.Speed: 3-3/4, 7-1/2 and 15.1/4 inch standard tape from 5 inch -10-1/2 size.Easy soft touch controls for the transport.Original remote control with 16 feet cord.New made patch-cords from XLR>RCA connections to the EQ and DBX.
When using this set-up:
only regular RCA input and output from the amplifier is needed.
This machine provides both NAB and IEC equalizers
switchable on the rear panel.This model can play both 2-track and 4-track tapes.
Recording can only be made in 2-track.
