General Description
The SRM 66 provides a cost effective solution for systems
requiring any combination of zone distribution, room combining, and remote level control. Split, route, and mix functions are
implemented with a six input, six output matrix mixer. The SRM
66 allows independent routing and mix-level adjustment of any
Input to any Output.
Control consists of a backlit LCD, five buttons and a Data
wheel. All programming is accomplished using eleven easily accessible edit pages. Six pages control Output programming, four
for Group programming and one for Memory functions.
Inputs and Outputs are line-level balanced and equipped
with Euroblock connectors. Rear panel Gain switches on each
Input and Output allow -10 dBV or +4 dBu sensitivity. Front
panel Mix Input Headroom LEDs indicate the remaining headroom for each of the six inputs at 4 dB and 16 dB.
Programmable Output Limiters prevent mixer overload. If
Output level exceeds the Limit Threshold, all six mix levels for
the given Output are reduced, maintaining the proper mix.
Each Output features an internally switchable 2nd-order 80
Hz Highpass filter. These filters are useful in conjunction with
constant-voltage line transformers or small sound-reinforcement
speakers.
The SRM 66 uses Output Groups to “link” attenuation levels
and Limiter gain reduction of one or more Outputs. Outputs
may be assigned to one of six Output Groups. For example, a stereo Output pair would typically be assigned to the same Output
Group. This ensures that they limit together and are controlled
by a common Output Group attenuation or Remote. Output
Group Levels are the only parameters not affected by Memory
changes.
Outputs are assigned to any one of the six possible Output
Groups or none. Remotes are then assigned to any one of the
six possible Output Groups or to the Master Group. The Master
Group is configured by assigning any number of the six possible
Groups to the Master Remote. For example, you have a six zone
system and have a Remote assigned to control the level in each
zone. You can then assign any number of the Output Groups to
the Master Remote, allowing all zones to be controlled by one
Remote.
Mix configurations are saved in up to 24 non-volatile
Memories stored in EEPROM, requiring no batteries. Memories
may be recalled via the front panel LCD screen or the rear panel
Memory Recall Port (MRP). The MRP allows remote contact
closures to recall any of the 24 Memories. Advanced MRP users
can completely program the MRP closure-to-memory-mapping
functions via SRM Exchange software and the Rane DSC 1 accessory. The optional Rane MRS 4, RCP 3 and RCP 4 connect
to the MRP for easy room combining and memory recall.
The SRM 66 provides a Remote Interface Port (RIP) which
supports up to seven optional SR 1L “Smart” digital Remote
controls. Each Remote may be assigned to any one of the six
possible Output Groups or to the Master Group. The Remotes
control the level of a Output Group, not Output level. Each of
the Memories stored in the SRM 66 may have unique Output
Group assignments for Outputs and SR 1L Remotes. This allows flexible room combining and system reconfiguration. All
Remotes assigned to an Output Group display the level of the
Output Group. The Remote Interface Port is a powered, half
duplex, (RS-485) party line system using 5 wires, allowing any
combination of “star” and/or “chained” wiring. The SR 1L also
supports encoder lockout and Master/Slave functionality where
one remote controls Output Groups across multiple SRM 66s.
The FP Lock function locks out all front panel SRM 66 control except for Output Group Levels and Memory Recall. The SR
1L Remotes can still control Output Group Levels with the FP
Lock rear panel switch engaged. With FP Lock, all edit pages are
viewable but not changeable.
The SRM 66 and SR 1Ls can be controlled via AMX or
Crestron room controllers using the SRM 66’s (RS-485) Remote
Interface Port (see RaneNotes “Using a Control System with and
SRM 66” and “Using SR 1Ls with other Rane Products”). All
RaneNotes are available at www.rane.com.

MRS 4 Memory Recall Switch
The MRS 4 provides a simple solution to
recalling SRM 66 Memories from a remote location via the Memory Recall Port. It fits in a standard U.S. electrical box, and can be covered with
a standard Decora™ plate cover. If connected in
normal mode, up to 4 Memories can be recalled.

DSC 1 Digital Serial Converter
The DSC 1 provides a bridge to connect a
PC’s RS-232 port and the Remote Interface Port
of the SRM 66. Coupled with the included SRM
Exchange™ software, the DSC 1 allows an exchange
of settings between an SRM 66
and the PC. Once the settings
are obtained by the PC they can be manipulated,
stored in a file, printed for future reference or sent
