REAR PANEL DESCRIPTION
FRONT PANEL DESCRIPTION
XLR INPUT jack:
Accommodates balanced signals. Rane adheres to the international and U.S. standard for balanced pin con-
figurations: Pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is signal return (negative)
.
Choose between this and
the ¼" TRS Input jack—use only one—they do not sum.
¼" TRS INPUT jack:
This TRS (Tip-Ring-Sleeve) ¼" jack accommodates either balanced or unbalanced signals. For an unbal-
anced signal use a mono ¼" plug (single conductor with shield). For a balanced signal use microphone cable (two conductor with
shield) with a TRS ¼" plug.
Choose between this and the XLR Input jack—use only one—they do not sum.
Refer to the included
RaneNote, “Sound System Interconnection” for unbalanced wiring.
XLR OUTPUT jack:
This balanced output is wired per AES standards of pin 2 “hot”, as described above in
.
¼" TRS OUTPUT jack:
This TRS (tip-ring-sleeve) ¼" balanced jack is compatible with either balanced or unbalanced systems.
For balanced systems, use a microphone cable wired with pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is
signal return (negative)
.
Refer to the RaneNote, “Sound System Interconnection” for unbalanced wiring.
LEVEL control:
Sets the level of signal coming into the ME 30B. Turn this control down if the OverLoad LED lights up steadily
(meaning too strong an Input signal). Since actual unity gain depends on varying slider settings (which is why we have not marked
a unity gain position on the front panel), use the BYPASS switch to determine the exact unity gain position of this LEVEL control
by comparing EQ and BYPASS volumes. The
OL
indicator lights up if any section of the ME 30B is within 3 dB of clipping. Oc-
casional blinking of this LED is acceptable, but if it remains on more than intermittently, turn down either the LEVEL control or
reduce the output level of the preceding component to avoid audible distortion.
BYPASS switch:
When the red LED is lit, this indicates that the unit is in the BYPASS mode: signal is routed directly from the
Input to the Output without passing through any active circuitry (often referred to as “hard-wire bypass”). Use this switch to com-
pare equalized and unequalized material, or to bypass the EQ section in the event of power loss or unit failure.
Filter RANGE switch:
The gain range of the filter sliders is switchable (as a group) from ±6 dB for high resolution, to
±12 dB for maximum boost/cut capability.
Filter level slide controls:
Each of these sliders controls the output level of each of the bandpass filters. Center position is
grounded for guaranteed flat response.
ON switch:
As you have astutely surmised by now, this switch powers up the ME 30B.
