The Mother Board and Repro Modules of the
mastering deck audio channels are similar to
those of the standard audio channels. Modules
unique to these audio electronics are the Front
anel Equalization Board and an output only ver ­
sion of the I/O Amplifier Module. Since this is a
reproduce only machine, there are no Bias or
Record Modules.
Specification for the mastering deck audio elec ­
tronics are listed in Table 1-6.
The mastering deck audio electronics are
mounted in extendable drawers similar to the
standard audio electronics. Two identical chan ­
nels fit into each drawer. The top drawer contains
the repro circuitry for the preview head, the bot ­
tom drawer contains the repro circuitry for the
repro head. High frequency and low frequency
equalization controls for each of the three speeds
are provided on the front panel. Alternatively, a
switch on the front panel can select preset
equalization (NAB or IEC).
