General Description
The RPM 2 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®. See the Drag Net data sheet for the
current software features and specifications.
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 2 provides two balanced, line-level analog inputs
and two balanced analog outputs, each I/O having 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 2 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 an RJ-45 Ethernet connector for com-
puter 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 105 dB throughput dynamic range and double-precision
48-bit internal DSP “math,” the RPM 2 offers the best DSP
algorithms and audio performance available.
This ain’t no Internet appliance! For example, theRPM’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. Current Preset, 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 compliant, the RPM 2 is compatible with any installation mandating
agency compliance.

Architectural Specifications
The device shall provide two balanced line-level inputs and two
balanced line-level outputs. The inputs shall be 100% controllable via software, including gains.
Analog audio inputs and outputs shall be accessible via rear
panel Euroblock connectors. A standard, low-cost Ethernet
switch shall be used to network and control multiple units via
10Base-T.
The signal processing configuration shall be 100% user
programmable under the Windows® XP operating system. The
control software shall provide complete display and control,
in graphical form, of all signal processing configurations and
functions. Downloadable via a rear panel, industry-standard,
Ethernet 10Base-T control port, the signal processing configurations shall be 100% drag and drop configurable (not fill in the
blanks) utilizing a variety of digital signal processing algorithms,
including but not limited to:
• Input & output gains with meters.
• Parametric bandpass, all-pass, high & low shelf & cut filters.

Control ports shall include 8 logic inputs for contact closure
preset recall or potentiometer level control. There shall be 24
internal, non-volatile Presets to store settings for later recall us-
ing a dedicated on-site computer or via external contact closure,
making the computer optional once the unit is programmed.
Contact closure ports shall be able to be paralleled for recalling
the same Preset number across multiple units. A recessed, rear
panel default switch shall provide recall of Preset 1 to restore the
unit to a known state in the event of communications failure.
All processing settings shall always be stored in nonvolatile
memory within the unit, thus allowing for power or computer
failure without loss of settings.
Data conversion shall be 24-bit, 48 kHz sampling rate using
up to 48-bit internal DSP processing with a minimum 104 dB
dynamic range.
The unit shall have no front panel controls, but shall provide
3-color LED meters for each input and output level. There shall
be front panel Power, Status, Ethernet, and control logic port
communications indicators, and an illuminated display of the
currently recalled preset. The rear panel shall provide Ethernet
Link and LAN indicators.
The device shall have certified compliance with FCC Part 15J
for a Class B computing device and EMCD 89/336/EEC (CE
certified). The device shall feature a built-in universal voltage
power supply capable of operating from 100 to 240 VAC, 50-60
Hz. The unit shall feature an IEC socket line cord. The unit shall
meet UL/CSA and CE safety requirements. The unit shall be
constructed of cold-rolled steel and mount into a standard 19"
1U EIA rack. The unit shall comply with the AES48 Grounding
Standard.
The unit shall be a Rane RPM 2 Programmable Multiprocessor.
