The RPM 88, RPM 44, RPM 22, RPM 26z, RPM 2m and RPM 2 are 100% drag and drop configurable DSP-based devices, set up and controlled using Rane's Drag Net software. Industry standard 10Base-T Ethernet is used to communicate between Drag Net devices and any Ethernet-equipped PC running Microsoft Windows. Drag Net offers the ultimate in signal processing flexibility, allowing you to draw the system you need without signal flow restrictions. Familiar Windows file management tools and Shortcuts are incorporated into Drag Net, allowing complete project management within a single interface.
The RPM 88 provides eight balanced, studio-grade analog inputs (selectable mic or line level), and eight balanced analog outputs. The RPM 44 and RPM 22 offer the same high-quality analog I/O, in 4 and 2 channel configurations respectively. A two-channel AES3 digital input and two-channel AES3 digital output are also provided on each, making the RPM 88 a true 10-input, 10-output device. All I/O, including the AES3 I/O, has its own, 100% user-defined signal processing path. The RPM's analog inputs feature software-controllable mic preamps with an equivalent input noise (EIN) of -128 dBu, satisfying even the most demanding audio applications.
Cost-effective end user control is possible using optional Rane accessories in conjunction with the RW 485 Remote Interface Port and Versatile Input and Output logic Ports. Whether your application requires contact closure Preset recall, remote level control using a potentiometer on a wall, or multi-zone source selection and smart, reconfigurable volume controls, Drag Net and the RPM 88 keep the user interface easy and inexpensive.
Euroblock connectors are provided for audio I/O, logic I/O and the RW 485 port. Grounding screws for direct connection to the metal chassis are provided for solving EMI problems due to shield wiring. Also found on the rear panel are standard XLR-type connectors for the AES3 I/O, an RJ-45 Ethernet connector for computer control and an IEC AC power input.
All DSP algorithms are not created equally and textbook DSP algorithms miss the mark where the rubber meets the road. Rane's team of audio-savvy DSP mathematicians -- a rare breed itself -- in conjunction with our industry-leading analog signal processing gurus have combined forces to offer superlative digital and analog audio performance. With 24-bit converters, greater than 106 dB throughput dynamic range and double-precision 48-bit internal DSP 'math,' the RPM 88 offers the best DSP algorithms and audio performance available. These ain't no Internet appliances! For example, the RPM 88's 400 MIPs translate into 225 fully parametric EQ filters, should you need multiple channels of 15 band parametrics and nothing else.
Multiple units are controlled from a single computer using low-cost Ethernet switches. The recessed Default button on the rear panel recalls Preset 1 in case of communications failure. The front panel has three-segment LED meters for each input and output, allowing fast and intuitive signal flow verification without a computer. Control Port, Power, Ethernet and Status indicators are also on the front panel. Powered from an internal UL recognized, CSA and CE certified power supply, the RPM 88 is compatible with any installation mandating agency compliance.
Drag Net is a Windows-based software application used to configure, control and monitor the RPM Series Programmable Multiprocessors and their remote controls. Drag Net features an intuitive drag-and-drop style user interface, with standard 10Base-T Ethernet connectivity for PC to RPM communication.

Depending on which remote is selected for the application, the end user is presented easy access to a variety of functions such as source selection, preset recall, and level adjustment. These are all easily mapped in Drag Net. All remotes mount in a standard U.S. electrical box with a minimum depth of 2-1/4 inches, and covered with a standard Decora® plate cover. Because of the display width, the SR 3 is the only remote that can’t fit next to itself in a 2-gang electrical box, but will fit next to any other remote.
Smart Remotes are compatible with the RPM 88’s Remote Interface Port, and electrically compatible with standard RS-485 interfaces. The various modes and parameters (e.g., Backlight Timer) are set directly when connected to a live device. Configurations can be created offline and saved as Storage files or user templates for subsequent upload to the remote at the job site. It is possible to assign a single remote to one or more parameters – to control a mono or stereo zone level, for example. It is also possible to assign multiple remotes to control the same parameter, as in a primary / secondary arrangement. Remotes linked in this manner automatically track each other’s changes, remaining in synch at all times. Smart Remotes require shielded CAT 5 cable with two twisted pairs.
Using any of the RPM series Versatile Input Port (VIP) voltage-controlled level inputs, the VR 2 provides a simple “pot-on-a-wall” solution, and the LRS 4 and MRS 4 provide 4-way radio button “switch-on-a-wall” solutions. Only three wires are required for connection.

All RPM models have Ethernet 10Base-T, 8 logic inputs, balanced Euroblock connectors.
RPM 2 and 26z are line in only. Other units are mic / line switchable in Drag Net.
From the Versatile Input Port, control almost any parameter from pot-on-a-wall, contact closures, or pre-made Remotes.
For more control, the RPM 22, RPM 44, and RPM 88 are the only models that can utilize the Smart Remote Controls. Up to 8 optional Smart Remotes (SR 2, SR 3, SR 4) can be connected via the RW 485 Remote Interface Port.
