The RPM 22 provides two balanced, studio-grade analog inputs (selectable mic
or line level), and two balanced analog outputs. The RPM 88 and RPM 44 offer
the same high-quality analog I/O, in 8 and 4 channel configurations
respectively. A two-channel AES3 digital input and two-channel AES3 digital
output are also provided on each, making the RPM 22 a true 4-input, 4-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 22 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 22 offers the best DSP
algorithms and audio performance available. These ain't no Internet
appliances! For example, the RPM 22's 200 MIPs translate into 125 fully
parametric EQ filters, should you need multiple 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 22 is
compatible with any installation mandating agency compliance.
