General Description
The SRM 66 provides a cost effective solution for systems
requiring any combination of zone distribution, room combin-
ing, 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 11 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 Limiters on each Output prevent mixer
overload. If Output level exceeds the Limit Threshold, all six
mix levels for the given Output are reduced, thus 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, say
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 Memories. These
non-volatile Memories are 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
MPR 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 (see RaneNote 142).
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 24 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 remote devices assigned to a
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.
(See the SR 1L Data Sheet and RaneNote 142.)
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.
Complete programmability of the MRP is possible using
the SRM Exchange software included with the Rane DSC 1
accessory (see the DSC 1 Data Sheet and RaneNote 142).
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 138 & 139). All
RaneNotes are available at www.rane.com.
