REAR PANEL INPUTS & OUTPUTS
IMPORTANT NOTE
CHASSIS GROUNDING
If after hooking up your system it exhibits excessive
hum or buzzing, there is an incompatibility in the ground-
ing configuration between units somewhere.
If your equipment is in a rack, verify that all chassis
are tied to a good earth ground, either through the line
cord grounding pin or the rack screws to another
grounded chassis.
This unit’s outboard power supply does not ground
the chassis through the line cord. Make sure that the unit
is grounded either to another chassis which is earth
grounded, or directly to the grounding screw on an AC
outlet cover by means of a wire connected to a screw on
the chassis with a star washer to guarantee proper contact.
Please refer to RaneNote “Sound System Interconnec-
tion” (supplied with this manual and available on request
at no charge separately) for further information on system
grounding.
INPUTS 1-4 RCA jacks
INPUTS 1-4 provide dedicated preamplifiers for Input
Channels 1-4 respectively. Each may operate in RIAA
PHONO or LINE mode.
PHONO/LINE switches
These switches set Input Channel preamplifiers 1-4 for
PHONO or LINE mode. Make certain these switches are set
correctly for your source.
PHONO GROUND
These lugs are provided to connect ground wires from
turntables. When using a turntable, proper grounding is
essential.
MIC 1, MIC 2 XLR jacks
The MIC 1 Input provides a dedicated balanced preampli-
fier for Input Channel 5, while MIC 2 provides the preampli-
fier for Input Channels 6. Each may operate in MIC or LINE
mode. Each of these preamplifiers features GAIN trim with
BASS and TREBLE tone controls.
MIC/LINE switches
These select MIC or LINE mode for the MIC Inputs. In
MIC mode, the gain range is 20 to 50 dB. In LINE mode, the
gain range is 0 to 30 dB. In addition to setting the proper gain
range for MIC or LINE level Inputs, these switches also
select the proper Input impedance.
MIC GAIN trim
These controls adjust the preamplifier for optimum
dynamic range. Each has a range of 30 dB, allowing a wide
range of sources to be used. To properly set this control, set
the associated front panel INPUT GAIN to “10”, turn the
MIC ENGAGE switch on and adjust the MIC GAIN so that
the input SIG/OL indicator flashes red only during very loud
peaks. The front panel INPUT GAIN control can then be
adjusted as required according to the instruction outlined
above under INPUT GAIN control.
MIC TREBLE and BASS controls
Separate TREBLE and BASS tone controls are provided
for each MIC preamplifier. These allow adjustment of the
tonal response of each Mic or Line source at the MIC Inputs.
If you add a significant amount of boost, you may need to
readjust the rear panel GAIN trims as outlined before.
