THE CONTROLS AND THEIR FUNCTIONS
INPUT SECTION
1. INPUT SELECTOR
This four-position input selector sets the input sensitivity
of the six channel inputs to -50, -35 or -20 dB. Note
also that the fourth position on channels 1 —4 is labelled
"TAPE", while the same position on channels 5 and 6
are labelled "PHONO L" and "PHONO R". When the
TAPE position on inputs 1—4 is selected, the corre­
sponding TAPE IN input (see rear panel) is selected as
input rather than the channel INPUT. When the PHONO
position on inputs 5 and/or 6 is selected, the correspon­
ding phono input channel (PHONO L or PHONO R) is
selected.
The -50/-35/-20 dB sensitivity positions on the input
selector allow you to match the input sensitivity of each
input channel to match the source —e.g. microphone,
electronic music instruments or line level sources. This
allows you to use just about any source on any input
channel without overloading the mixer's electronics. Most
microphones —especially dynamic types —will work best
with the -50 dB input setting. Some high-output con­
denser and electret mics may require the -35 dB setting.
PRECAUTIONS
Be sure to turn down all faders when making input/
output connections.
Do not expose the RM602 to direct sunlight or other
sources of heat such as radiators, etc.
Irreparable damage may result from opening the
RM602 cabinet or attempting to alter the internal
circuitry.
Avoid dropping your RM602 or subjecting it to any
type of shock, as impaired performance may result.
Do not attempt to clean the RM602 with benzine or
other solvents, as these may cause discoloration or
deformation of the cabinet. Clean the unit with a soft,
dry cloth.
