QUICK START

Before complaining about having to install the 

SRM 66

 in the rack twice (because you forgot to set the internal

highpass filters ahead of time), take note that the very first (non-joke) line in this manual is: Before installing the 

SRM 66

in a rack, be sure the internally switchable 80 Hertz highpass filters are set as desired. They are shipped with the filters in

the OUT (disabled) position. (See the bottom of page Manual-2 to enable these filters.) If you were smart enough to read

this much of the manual, this paragraph may already have saved you a few minutes of your life – you’re welcome. If

you’ve learned the hard way, hopefully you’ve learned an important lesson – read at least the first line in the manual first.

Make all connections with the power and amplifiers off. The 

SRM 66

 is fully balanced and equipped with removable 5-

position 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 (on rear) is in the out position to enable programming from the front panel.

Apply power so the 

PWR

 LED lights 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 Input 

GAIN

 switches. Adjust so that 

4 dB

 lights during peaks.

Navigating the LCD Edit pages is simple. The top buttons marked 

 and 

>>

 are the left/right Page scroll buttons.

These navigate to Output pages 1 through 6, the assign Outputs to Output Group page, the assign Remote to Group page,

the assign Group to Master Remote 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 Output 1’s page. Move the cursor under 

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 Output 1. 

MST

controls the Master level of Output 1. 

LIM

  sets the Limit Threshold of the Limiter circuit for Output 1.

To Copy settings from Output 1 to any other Output, 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 Output.

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 information on remote control of Memories, level adjustments and, the

most powerful feature of the SRM 66, Output Groups which “link” Output levels. A Master Remote feature allows control-

ling the level of any Output Groups assigned to it.

To maintain signal control over the specified dynamic range, the Master output should be turned off when no inputs are

routed to a given output.

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 substitute.

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 – which

are consequences of unbalanced operation – keep cable

lengths as short as possible. For lengths longer than ten feet,

use a transformer such as a Rane BB 44x.

Coming from an unbalanced source, the SRM 66’s Input

uses two conductors plus a shield; connect ‘+’ to ‘+’, the

unbalanced source ground to ‘–’, and the cable shield to the

SRM 66’s ground.

Going to an unbalanced device using a single conductor

plus a 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 and

grounding requirements.
