The RPM 26i provides all required signal processing
between the mixer and amplifiers. With its insightful,
preprogrammed configurations and user-friendly RaneWare®
software, the RPM 26i includes a wide variety of intuitive
signal processing functions: high & low cut filters, compression, delay, crossover, parametric EQ, splitting, input summing, limiting, trim controls and sine wave or pink noise test
tones.
The RPM 26i contains a stereo AES3 input, 6 analog
outputs and saves several rack spaces with its tamperproof,
dead-front, 1U chassis. Configurations and settings are stored
in 16 internal, non-volatile memories—which are contact
closure accessible from the rear panel Memory Recall Port.
This Port can be paralleled with the Ports of other RW 232
products—allowing one hardware switch to select entire
system configurations. This makes the RPM 26i ideal for
installations requiring preset configurations through simple
contact closures. All 16 memories are accessible from
RaneWare’s Site Control Panel.
The RPM 26i is programmable via its rear panel RW 232
port that interfaces directly to the RS-232 ports found on PC
compatible computers. This eliminates the need for a special
cable, box or interface card. Up to sixteen RW 232 units at a
time can be serially linked to a single computer. Thus a sound
system installer can access and program each device on line
without having to unplug from the first device and plug into
the next. The RW 232 port is also compatible with AMX and
Crestron controllers. Once the RPM 26i is programmed, the
computer is strictly optional.
The RPM 26i employs an AES3 receiver with highperformance sample rate converter & D/A converters with
24-bit double-precision internal DSP processing. Euroblock
connectors are provided for audio and the Memory Recall
Port. The recessed Default button on the rear panel recalls
Memory 1 in case of computer failure. The Device Address
switch assigns one of 250 possible RW 232 addresses that
uniquely identifies each device on the RW 232 bus. The front
panel has two-color, signal present and overload indicators
for both the Inputs and the Outputs—allowing for fast and
intuitive signal flow verification without the need of a
computer. Power and COM (communications) indicators are
also on the front panel to verify proper AC supply and
communication with the computer.
Powered from a UL listed, CSA and CE certified remote
power supply, the RPM 26i may be used in any installation
mandating agency compliance.

Data Sheet-1
Rane’s easy-to-use, Windows-compatible software—
called RaneWare (included with the unit and available on our
website at http://www.rane.com)—allows the RPM 26i (and
other RW 232 units) to be controlled in real time. RaneWare
also supports saving memories—which include configuration
changes—to a file. This allows programming units without
being physically connected to them, and allows different
configurations to be stored in each Memory. Thus units may
be initially programmed at the office, then “tweaked” on site.
The software provides password security, allowing only
memory changes, thus disallowing further access. The
software also provides metering for Input trims, A/D “number
of bits toggling,” and Compressor Gain Reduction meters.
“Stereo” Linking of Input Trims, Delays and Output Trims as
well as Combining of Compressors and Limiters are also
supported. Frequency steps for High and Low Cut filters,
Crossover and Parametric EQ are adjustable in 1 Hertz steps.
The Crossovers and Extended Parametric EQ (included in
some of the preprogrammed configurations) support Linkwitz-Riley, Bessel or Butterworth filters (12, 18 or 24 dB/
Octave, where applicable). All Parametric EQs contain ¼ dB
boost/cut steps with a +12 / -15 dB range and 80 Q steps
between 40 and 0.5 (bandwidths between 0.036 and 2.54
octaves, respectively). Double clicking on the software’s
Output terminal displays the computed Overall Response
curve for the Output(s). This screen allows independent
viewing of the frequency response contribution of the Input
EQ (High & Low Cut or PEQ Filters), the Crossover (if
applicable) and the Output (Parametric) EQ. Ramping can be
enabled for smooth transitions between parameter settings, or
disabled when not needed (during setup, for example).
RaneWare also prints device reports containing all of the
device’s parameter settings, along with each Output’s Overall
Response curve.

internal, non-volatile memories for storing settings for later
recall via a dedicated on-site computer or via other RS-232
compatible means. Contact closure recall of the memories
shall be provided via a rear panel Euroblock connector,
making the computer optional once programmed. Contact
closure ports shall be parallelable for recalling the same
memory in multiple units. Each memory may contain a
unique signal processing configuration. A recessed, rear panel
default switch shall provide recall of Memory 1 in case of
computer failure. All processing settings shall always be
stored in non-volatile memory inside the unit, thus allowing
computer failure without losing settings.
Active balanced analog inputs and outputs shall be
accessible via rear panel Euroblock connectors. Signal
processing configurations and settings shall be accessible via
a rear panel RS-232, DB-9 input port. Up to 16 units at a time
shall be daisy-chained via a rear panel RS-232 output port.
The rear panel device address switch shall uniquely identify
each unit on the RW 232 bus.
The front panel shall provide independent input and
output, dual-color signal present (green) and overload (red)
indicators. Level indicators shall provide throughput signal
flow verification without need for a computer. There shall be
front panel power and communications indicators.
The control software shall provide complete display and
control, in graphical form, of all signal processing configurations and functions. Most signal processing settings shall be
displayed from a single computer screen. All settings shall be
accessible via dialog boxes and printable in device reports.
There shall be means to backup all settings to a computer file
for later recall or editing. Graphical plots of the calculated
frequency response of each processing function and an
overall response plot shall be provided.
The unit shall have certified compliance with FCC Part
15J for a Class B computing device and EMCD 89/336/EEC
(CE approved). The unit shall be powered from a UL listed,
CSA certified remote power supply meeting LVD 73/23/EEC
and EMCD 89/336/EEC standards. The unit shall be constructed entirely of cold-rolled steel.
The unit shall be a Rane Corporation RPM 26i DSP
Multiprocessor.
