- A Pair of Mixers may be Configured for Stereo Audio
- Module is Configured and Adjusted Using Network Control Software
- Compatible with RDL Networked Remote Controls
- Provides Level Adjustment in 1 dB Steps for Each Input of Each Mixer
- Provides Level Adjustment in 1 dB Steps for the Output of Each Mixer
- Automatic (VOX) Priority Ducking Assignable on Each Virtual Mixer
- Priority May be assigned to One of the Four Received Network Channels
- Selectable High Pass Filters for the Priority Input
- Adjustable Ducking Threshold, Attenuation Level and Recovery Delay
- Provides Four Stored Preset Configurations for Routing, Mixing and Levels
- Presets Activated by Network Commands, at Power-Up, or Using RDL RC4M Remote Control
- LED Indicators for Power and Network Sync
- Operation from PoE Power (Class 0, IEEE 802.3af) or external 24 Vdc

Network Connector: RJ45 with Link and Speed indicators
Digital Audio Ethernet Protocol: Dante or AES67
Digital Audio Sources (4): Dante or AES67
Transmission Rate: 100 Mbps
Sample Rates Supported: 44.1 kHz, 48 kHz (default)
Bit Depth Supported: 24 bits
Digital Audio Outputs (4): One output channel per virtual mixer (1 through 4)
Outputs (2): +4 dBu (nominal, -20 dBFS), 150 Ohms
Output Connection: Detachable terminal block
Frequency Response: 20 Hz to 20 kHz (± 0.25 dB)
THD+N: < 0.01%
Noise below +4 dBu: < 85 dB
Crosstalk: Below noise floor (20 Hz to 20 kHz, -20 dBFS)
Headroom above +4 dBu: > 18 dB
Note: All 6 virtual mixers use the same four network audio sources.
Note: Each mixer output is connected to one RU-NMP44 output.
Note: A mixer that is using only one input acts as a virtual VCA.
Note: A mixer that is using one standard and one priority input acts as a paging / ducking module.
