R P M 26
The RPM 26 provides all required signal processing between the mixer and amplifiers. With its insightful, preprogrammed configurations and user-friendly RaneWare ® software, the RPM 26 includes a wide variety of intuitive signal processing functions: high & low cut filters, compres sion, delay, crossover, parametric EQ, splitting, input sum ming, limiting, trim controls and sine wave or pink noise test tones.
The RPM 26 contains 2 analog inputs, 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—8 of which are contact closure accessible from the rear panel Remote Switch Interface (RSI) port. This interface can be paralleled with the RSI ports of other RW 232 products—allowing one hardware switch to select entire system configurations. This makes the RPM 26 ideal for installations requiring preset configurations through simple contact closures. All 16 memories are accessible from RaneWare’s Site Control Panel.
The RPM 26 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 250 RW 232 units 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 26 is programmed, the computer is strictly optional.
The RPM 26 employs the latest 18-bit A/D & D/A convert ers and analog level control ICs from Crystal Semiconductor.
Euroblock connectors are provided for audio and Remote Switch Interface connections. 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 communications with the computer.
Powered from a UL listed (approval pending), CE certified (approval pending) remote power supply, the RPM 26 is exempt from safety agency requirements, and may be used in any installation mandating agency compliance.
Rane’s easy-to-use, Windows-compatible software—called RaneWare (included at no extra cost and available on our website at www.rane.com)—allows the RPM 26 (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, respec tively). 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.
When required, Optional input isolation transformers (Rane part #150-010) are available.
