OPERATORS MANUAL

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-posi-

tion 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.

WEAR PARTS:

 This product contains no wear parts.

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 ampli-

fier 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 controlling the level of any Output 

Groups assigned to it.

For best signal control and dynamic range, turn the Master 

Output 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 telephone 

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.
