General Description

The RPM 26z is a 100% drag and drop configurable DSP-based device, 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 26z provides two balanced, line-level analog inputs and six balanced analog outputs. A two channel AES3 digital input is also provided making the RPM 26z a true 4-input, 6-output device. All I/O, including the AES3 input, has its own 100% user-defined signal processing path.

Cost-effective end user control is possible using optional Rane accessories in conjunction with the Versatile Input Port. Whether your application requires contact closure Preset recall or remote level control using a potentiometer on a wall, the RPM 26z keeps the user interface easy and inexpensive.

Euroblock connectors are provided for audio and logic I/O. 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 is a standard XLR-type connector for the AES3 input, 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 104 dB throughput dynamic range and double-precision 48-bit internal DSP 'math,' the RPM 26z offers the best DSP algorithms and audio performance available. See the RaneNote Superior Audio Requires Fixed-Point DSP for more information.

This ain't no Internet appliance! For example, the RPM 26z's 215 MIPs translate into 150 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-color 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 power supply and certified as UL, CSA and CE complient, the RPM 26z is compatible with any installation mandating agency compliance.

MRS 4 Memory Recall Switch The MRS 4 provides a simple solution to recalling Memories from a remote location for products having an MRP (Memory Recall Port) or a VIP (Versatile Input Port). These are radio buttons: engaging one button (in, changing to green) causes any of the other three to disengage (out, changing to black). Space is provided next to each button for labelling. The MRS 4 is intended for use in Normal mode, allowing up to 4 Memories to be recalled by contact closure. Consult the Operators Manual of the connected Rane equipment for details on Memory recall functions. The MRS 4 mounts in a standard U.S. electrical box with a minimum depth of 2-1/4 inches, and flush covered with a standard Decora plate cover (not included). MRS 4 Data Sheet (100k)
LRS 4 Level Recall Switch The LRS 4 provides a simple interface to end users requiring four predetermined volume levels (may include mute) when used in conjunction with devices equipped with voltage-controlled level inputs. The LRS 4 contains four radio buttons: engaging one button (in, changing to green) causes any of the other three to disengage (out, changing to black). Space is provided next to each button for labeling. The LRS 4 accepts a two-wire DC voltage input (V+ and ground) and outputs a single voltage (Vout) that is varied depending on the selected LRS 4 button. Thus, four volume levels can be setup during installation: selecting the top button provides the maximum or highest output voltage (~V+) typically the highest volume. Select the second and third buttons for two different installer-programmable lower volumes. The bottom button grounds the output pin thus providing the lowest voltage output typically the muted condition. The LRS 4 fits in a standard U.S. electrical box with a minimum depth of 2-1/4 inches, and flush covered with a standard Decora plate cover (not included). Consult the Operators Manual of the connected Rane equipment for details on Memory recall functions. LRS 4 Data Sheet (100k)
VR 2 Volume Remote The VR 2 Volume Remote connects to the VIP Port (Versatile Input Port) of the RPM 26z to adjust volumes from remote locations. Simply put, the VR 2 is a 20k ohm potentiometer with a 3-pin Euroblock connector mounted in an easily installable package. The VR 2 mounts in a standard U.S. electrical box with a minimum depth of 2-1/4 inches, and flush covered with a standard Decora plate cover (not included).
