SECTION I. GENERAL INFORMATION
The MX-5050 MK HI-2 Recorder is a professional quality two-speed
audio tape recorder/reproducer, designed for optimum performance
and long life.
It accommodates a 1/4 inch tape, 7-1/2 ips (19.05
cm/sec) and 15 ips (38.1 cm/sec) tape speeds.
1.1 SYSTEM DESCRIPTION
Among the many professional features of the MX5050MKHI-2 are:
selective reproduction, motion sensing, an edit control that
permits spilling, an adjustable cueing control for audible moni­
toring in the fast-forward and rewind modes, a built-in two
frequency low distortion test and cue-tone oscillator, a com­
puterized elapsed time indicator with a digital LED display,
front adjustable record bias, equalization, and level controls,
active balanced input and output circuits, a reference flux level
indicator on the front amplifier panel, a standard reference
level output switch, separate line and microphone input level
controls for each channel, switches for recording levels, equal­
ization, microphone, and output level attenuators, play-back
equalization pots for each speed, a memory stop button for auto­
matically searching the zero tape time location with F. FWD or
RWD mode, ceramic tape guides, big head housing, lower transport
noise, and xmproved specifications for distortion, erase effect,
and signal and noise ratio.
1.1.1 TAPE TRANSPORT
All components of the tape transport system are mounted on a
rigid aluminum frame for stability. The transport design in­
corporates two 6-pole induction motors for the reels and a 3-
speed DC servo motor (Direct drive) for the capstan.
Speed selection is made by a front panel push-button switch which
also switches the equalizer.
The transport accommodates tape reels of 10-1/2 inches, 7 inches,
and 5 inches in diameter with NAB or EIA hub configurations.
A
solenoid-actuated tape lifter lifts the tape away from the heads
in the fast forward and rewind modes, in addition to the stop
mode, to increase head and tape life.
In addition to the editing controls, a tape-splicing block (Fig.
3-3) mounted on the head cover holds the tape for ease of editing
Momentary contact push-button switches on the transport are used
to select operational modes: record, play, stop, rewind, and
fast forward. These modes may be controlled from a remote loca­
tion by means of an optional remote control unit (page 1 - 5 ) .
