Record, Reproduce, and Bias circuit boards are
plug in modules which mount directly onto the
Mother Board. The channel electronics can be
easily removed from the drawer by removing two
screws in the front panel and four screws in the
Mother Board. All connections to the Mother
Board are made via plug in connectors. Since all
the channel electronics are identical, modules

The standard JH-110B audio electronics are
housed inside a 3-1/2 by 17-3/4 by 12-1/8 inch
drawer (8.9x45.1x30.8 cm). Each drawer holds two
channels of audio electronics. Single track op ­
tions contain one channel mounted in the left side
and a blank panel covering the right side of the
drawer. Variable profile cabinets hold one or two
drawers; high profile cabinets hold two or four.
These drawers extend from the cabinets on
latching slide rails for access to the audio printed
circuit boards and components. Audio input, out ­
put, and power connectors are located at the rear
of the drawers. The drawers can be extended on
their slide rails without disconnecting any cables.
