Rane SRM 66 Operator's Manual

QUICK START
Make all connections with the power and amplifiers off. The SRM 66 is fully balanced and equipped with removable
5-wire Euroblock connectors. Inputs and Outputs are arranged on Euroblocks in pairs, i.e. 1&2, 3&4, 5&6.
Be sure the FP LOCK switch is in the out position to enable programming from the front panel.
Apply power so the PWR light and LCD screen glows with the SRM 66 welcome marquee. During initialization, The
startup muting circuit immediately starts counting down from 40 in the Limiter Gain Reduction area of the display. Adjust
the VIEWING ANGLE with a miniature screwdriver if necessary.
With signal applied to the Inputs, watch the MIX INPUT HEADROOM indicators. These verify correct setting of the
Output of the previous device and the rear panel GAIN switches. Adjust so that 4 dB lights during peaks.
Navigating the Edit pages is simple. The top buttons marked << and >> are the left/right Page scroll buttons. These
navigate to the Channel pages 1 through 6, the Assign Channel to Group page, the Assign Remote to Group page, the
Group levels page, and the Memory page.
The bottom buttons marked < and > are the left/right cursor buttons. These select the (underlined) parameter to edit.
Rotating the DATA knob changes the parameter setting.
Let's start by navigating to Channel 1's page. Move the cursor to IN1. With a signal driving Input 1 and a working
amplifier connected to Output 1, adjust the DATA knob to the desired level. Adjust any other Input going to Channel
Output 1. MST controls the Master Output level of Channel 1. LMT sets the Limit Threshold of the Limiter circuit. for
Channel 1.
To Copy settings from Channel 1 to any other Channel, move the cursor to COPY. Press the EXE button. The display
now reads PASTE. Change the page to the one you want these same settings in, and press EXE again. The settings have
now been pasted into the new Channel.
Settings may be Stored and Recalled in the Memory Page. To Store, select the Store field, select a Memory number
with the DATA wheel and press EXE. To Recall, select the Recall field, select a Memory number with the DATA wheel
and press EXE. Look deeper into this manual for remote control of Memories and level adjustments.
CAUTION: Never connect anything except an approved Rane Power supply to the thing that looks like a red tele-
phone jack on the rear of the SRM 66. This is an 18 VAC center tapped power input. Consult the Rane factory for a
replacement or substitution.

SRM 66 CONNECTION

Balanced Operation
Connect the '+' to '+', '–' to '–', and shield to shield. Use
only when driving from a true balanced source and driving to
a true balanced destination—either transformer coupled or
active drive.
Unbalanced Operation
To avoid nasty side effects such as hum and noise, this is
to be avoided—but when you must, keep cable lengths as
short as possible. For lengths longer than ten feet, use a
transformer or a Rane BB 44x.
Coming from an unbalanced source into the SRM 66
using two conductors with shield, connect '+' to '+', the

SPLITTER ROUTER MIXER
unbalanced source ground to '–', and the cable shield to the
SRM 66 ground.
Going to an unbalanced device using a single conductor
with shield, connect '+' to '+', leave '–' unconnected and
connect the cable shields at both ends to ground.
Combination Operation
For combined balanced and unbalanced operation, use
whichever half of the above instructions apply for each end.
See the "Sound System Interconnection" RaneNote
included with this manual for more information on cabling
