RPM 88 Description

The RPM 88 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 88 provides eight balanced, studio-grade analog inputs (selectable mic or line level), and eight balanced analog outputs. A two-channel AES3 digital input and two-channel AES3 digital output are also provided, 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. The rear panel has 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.
