R-55 / Mar 2003
ANALOG OUTPUTS — R-55 consoles use an electronically bal-
anced output circuit. Care must be exercised when connecting them to an
unbalanced system. While temporarily shorting the low side of the output
signal to ground will not cause any problems, continued operation will
result in increased distortion, decreased reliability, and possible oscilla-
tion problems. If you must connect the output to an unbalanced system, be
sure to leave the low side unterminated, and connect the unbalanced
system to the high side output and shield connections.
Modules Layout
The R-55 console’s mainframe comes supplied with 12 line level input
modules, an output module, and a control room/studio module. Each
module type has its assigned slot (see drawing on page 1-10). To handle
mic level inputs, a quad mic preamp is included. Also there can be optional
modules: a superphone, a line select module, and a tape remote module.
Optional modules can be placed in any input slot.
