Manual-3
Rear Panel Description
POWER input connector.
Use only an RS 1, or other Remote AC power supply approved by Rane
. This unit is supplied with a
remote power supply suitable for connection to this input jack. Consult the factory for a replacement or a substitute. This unit’s
power input is designed for an AC supply, delivering 18 volts, from a center-tapped transformer capable of supplying at least the
750 mA of current demanded by this product. Using any other type of supply may damage the unit and void the warranty.
Chassis ground point.
A #6-32 screw is supplied for chassis grounding purposes. Units with external power supplies such as this
SRM 66 supply do not ground the chassis to earth through the line cord. This chassis connection is critical and in most instal-
lations, required by law. Many chassis ground this point to an amplifier chassis ground or directly to the grounding screw on a
grounded AC outlet cover by means of a wire secured on both ends with star washers to guarantee proper contact. See the Chassis
Grounding note on the next page.
FP LOCK button.
When pressed
in
, locks out all front panel control except for Group Levels and Memory Recall. The
SR 1L remotes (sold separately) are also able to control Group Levels with FP LOCK engaged. The user is able to view, but not
edit, all Edit pages.
MEMORY RECALL PORT (MRP).
This Port allows any remote switch to recall any of the system Memories. The first eight
Memories recall with simple switch closure to a single pin. A “binary” wiring mode allows access to more complex Memory recall
functions. See Figure 8 on page Manual-8. Complete programmability of the MRP is possible using the
Edit MRP Configuration
feature found in SRM Exchange software. See
DSC 1 & SRM Exchange software
on page Manual-9.
REMOTE INTERFACE PORT (RIP).
This Port supports up to seven optional SR 1L “Smart” digital Remote controls (see page
Manual-6). Each Remote may be assigned to adjust the Level of any one of the six SRM 66 Output Groups or the Master Group.
OUTPUT GAIN switches.
These assist setting the optimal gain structure of the Output stage, depending on what the following
device would like to see (or hear). Balanced signals usually require a +4 dBu setting (button
out
), and unbalanced signals usually
require the -10 dBV setting (button
in
).
OUTPUTS.
These balanced Euroblock connectors may be wired balanced or unbalanced. See page Manual-1 or the RaneNote,
“Sound System Interconnection” later in this manual for assistance.
INPUT GAIN switches.
These assist setting the optimal gain structure of the Input stage, depending on the level from the previ-
ous device. Balanced signals usually require a +4 dBu setting (button
out
), and unbalanced signals usually require the -10 dBV
setting (button
in
). Use the MIX INPUT HEADROOM meters as a guide for determining GAIN switch position (see
in the
Front Panel Description).
INPUTS.
These line-level balanced Euroblock connectors may be wired balanced or unbalanced. Microphones require a pream-
plifier (see the Rane MS 1B for a solution). See the next page and the RaneNote “Sound System Interconnection” elsewhere in this
manual for assistance with various wiring options.
