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 . 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.

FRONT PANEL DESCRIPTION Out[x]:[y] IN1 IN2 IN3 IN4 Copy +6 -3 +6 Off IN5 IN6 MST LIM +6 -25 +0 Max MIX INPUT HEADROOM meters. These assist setting of the rear panel GAIN switches as well as the output level of the preceding device. The 16 dB and 4 dB LEDs indicate the remaining headroom for each of the six Inputs. Optimal settings allow the 4 dB LEDs to flash only during signal peaks. Edit Pages.

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.

OPERATION The User Interface All SRM 66 programming is done with the Data wheel and the front panel buttons using one of the eleven LCD pages. Each page consists of the page name, multiple parameter fields and possible Command fields and status indicators. To navigate between pages use the Next Page (>>) and Previous Page (<<) buttons. Within a page the Next (>) and Previous (<) buttons move the cursor to each field. Above each parameter field is a label indicating its function.

Group attenuation levels page. This has the same action as controlling from optional SR 1L Remote(s). Group Lvls Zero All G1 -20 Groups G1 through G6 and MST may be attenuated 0 dB to -29 dB or set to Off. G2 -10 G3 0 G4 Off G5 0 G6 -6 MST 0 When Zero All is selected, pressing EXE sets all Group attenutation levels to 0 dB. Remote to Group Page, where Remotes are assigned to 1 of 7 Groups, or Off. Rmt->Grp Copy Remotes R1 through R7 may be assigned to 1 of 6 Output Groups, Master, or Off.

SR 1L Troubleshooting Double-check all wiring for accuracy before power is applied via the SRM 66. A single LED on the SR 1L should light immediately after SRM 66 power is applied. A blinking LED indicates that it has not yet detected communication on the Port. This is common until the SRM 66 has fully initialized but should not happen after that point. If after hook up and SRM 66 power up, an SR 1L LED blinks or does not respond, one of several problems is to blame.

APPLICATIONS One of the best ways to grasp the true versatility of the SRM 66 is to observe one in action. Figure 11 shows an installation using one SRM 66 to distribute sound throughout an entire manufacturing facility. Each Output can have different mix Inputs and Levels. For example, the offices may mix in a different page source than the shop floor. Also note that all three of the shop floor Outputs may have different mixes, Master Levels and Limiter thresholds.
