Inputs: Up to 8 mic/line plus
AES3 digital (depending on
the RPM model). Daisy-chain
more with AES3 I/O.

Device Configuration window

• What you see is what you get – If a control is shown and DSP usage <100%, use it!

• Multi-select cut/copy/paste and block alignment tools.

• Remotely addressable Level & Preset recall controls.

• Tags on processing blocks display the last recalled preset.

10Base-T Ethernet

• View the Preset elements from the Processing Map or from the Preset block list.

Remotes: End-user Levels
and Presets can be assigned
to Remotes, installed near the
source or inside the zone.

Outputs: Up to 8 balanced
line outputs plus an AES3
digital output (depending
on the RPM model).

Meter Window

• Consolidates all
input and outputs
into a resizeable
and dockable
meter bridge.

Preset window

• Preset overlay feature allows changing
one, some, or all parameters.

• Settings can be stored in 24 internal,
non-volatile Presets.

• Recall the rst 8 Presets via remote con­tact closures (see Remote Mapping).

Parameter window

• Displays a tree structure view of all used
signal processing and control blocks.

• Associates parameters to remote controls
(contact closures, Smart Remotes).

• Drag-and-drop into the Preset window
to quickly build Presets.

Palette window

• Lists signal processing blocks
used to create the audio ow.

• Drag and drop blocks from the
Palette to the Device Con­guration window to build your
custom audio system.

Processing Blocks

Inputs and Outputs

• Input block features vary depending on RPM hardware.
 RPM 88/44/22/2m: mic or line, +48V Phantom Power.
 RPM 88/44/22: AES3 digital I/O with sample rate conversion.
 RPM 26z: line-level only, analog gain trim.
 RPM 2: line-level only.

• Software controlled mic/line Inputs (RPM 88/44/22/2m):
 -128 dBu EIN (mic) with +48 VDC Phantom Power.
 Coarse Gain from +15 to +60 dB in 15 dB steps.
 Fine Trim from +16 to -20 dB in 1 dB steps.

• Line-level Balanced Output Trim maintains highest signal-to-

noise for all gain settings.

• Intuitive gain structure GUI.

Priority Auto Mixer / Ducker

• Advanced music and paging processor, with all the elements for

multi-zone paging and priority program management.

• A variety of In/Out combinations are available, up to 8 x 8.

• Automatic detection of input signal with noise immunity.

• Push-to-Talk operation from VIP Port contact closure.

• Forced on from properties window.

• Cross-point assignment of any input to any output.

• Eight priority levels for each input, arbitrated at each crosspoint.

• Priority based Ducking at each crosspoint.

• Priority dependent NOM mode preserves gain-before-feedback.

Applications:

• Automatic, priority paging with auto detection or Push-to-Talk.

• Automatic, priority based program selection.

• Simple, priority based ducking.

• NOM-based automatic mixing.

Deluxe Stereo or Mono Side-Chain Compressor

• Smooths out program dynamics, with soft knee adjustment.

• Uses true rms level detection. A side-chain allows lters in the

detector path as well as an input for ducking applications.

• Provides initial default settings for music and speech.

Ambient Noise Compensator

• Automatically boosts program levels to match changes in back-

ground noise level.

• Connect any music or paging source to the Program input, and

the noise sensing microphone to the Ambient input.

Automatic Gain Control (AGC)

• Versatile gain riding block helps maintain the appropriate signal

level and dynamic range for an application.

• Allows transparent control of both speech and music levels.

• Uses a side-chain with true rms level detection, allowing lters

in applications that benet from band-limited detection for
voice or instrument AGC. It is also possible for the detector to
use signals other than the gain-controlled-signal.

Up to 10 inputs / 10 outputs!

Parametric Equalizer (PEQ)

• Add/Remove Filter feature easily changes the number of l­ters without deleting the block or recreating settings. Up to 15
lters can be added to each PEQ block. Adjust lter quantities
oine without redrawing blocks and signal ow.

• Each numbered icon in the graph represents an available EQ
lter. ese icons can be selected and dragged about the graph
to adjust the frequency (horizontal) and level (vertical) param­eters, or precise values may be entered.

• Separate views for Magnitude, Phase, Composite, and indi­vidual lters. Tab display of all lter parameters in list form.

Feedback Suppressor

• 5, 10 & 15 lter versions for optimum use of DSP resources.

• Fixed, oating and user-adjustable PEQ lter types.

• Reset oating lters on power up or user-dened timeout.

• Speech and music modes.

• Auto-setup mode with limiter for fast setup.

• Dynamic level control.

True Response Graphic Equalizer with Perfect-Q™

• Rane’s patent-pending Perfect-Q technology means Drag
Net equalizers have no band interaction, even with drastic
adjustments of adjacent bands (blue line). But you can still
select traditional Proportional Q if desired (red line).

2-way or 3-way Crossover

• Adjust crossover frequencies by selecting and dragging the
crossover point icon to a new location, or type in values. Fil­ters may be linked and adjusted simultaneously.

• In Simple Mode, all crossovers are Linkwitz-Riley, 24 dB per
octave.

• Advanced Mode may include any combination of:

Linkwitz-Riley 12 or 24 dB per octave


 Butterworth 12/18/24 dB per octave
 Bessel 12/18/24 dB per octave
 1st-order 6 dB per octave lter.
