技術仕様

Power Sources

  • Power-over-Ethernet (PoE): class 3 (medium power) per IEEE 802.3af
  • External: 10 to 18 Vdc, 1.0 A max @ 12 Vdc

Network Audio Technology

  • Type: Dante audio-over-Ethernet
  • Bit Depth: up to 24
  • Sample Rate: 48 kHz
  • Number of Transmitter (Output) Channels: 2
  • Number of Receiver (Input) Channels: 2
  • Dante Audio Flows: 4; 2 transmitter, 2 receiver
  • Analog to Digital Equivalence: a +4 dBu input with 0 dB gain selected results in a Dante digital output level of –20 dBFS

Network Interface

  • Type: twisted-pair Ethernet, Power-over-Ethernet (PoE) supported
  • Data Rate: 100 Mb/s (10 Mb/s Ethernet not supported)

General Audio

  • Frequency Response (PL to Dante): –0.3 dB @ 100 Hz (–4.8 dB @ 20 Hz), –2 dB @ 8 kHz (–2.6 dB @ 10 kHz)
  • Frequency Response (Dante to PL): –3.3 dB @ 100 Hz (–19 dB @ 20 Hz), –3.9 dB @ 8 kHz (–5.8 dB @ 10 kHz)
  • Distortion (THD+N): <0.15%, measured at 1 kHz, Dante input to PL interface pin 2 (0.01% pin 3)
  • Signal-to-Noise Ratio: >65 dB, A-weighted, measured at 1 kHz, Dante input to PL interface pin 2 (73 dB, PL interface pin 3)

Party-Line (PL) Intercom Interface

  • Type: 2-channel analog PL, unbalanced (pin 1 common; pin 2 DC with channel 1 audio; pin 3 channel 2 audio)

  • Analog Audio Level: –10 dBu, nominal, +3 dBu maximum, PL interface pin 2 (+7 dBu, PL interface pin 3)
  • Call Light Signal Support: 20 kHz, ±1%
  • Mic Kill Signal Support: 24 kHz, ±1%

Party-Line (PL) Hybrids: 2

  • Topology: 3-section analog circuitry compensates for resistive, inductive, and capacitive loads
  • Nulling Method: automatic upon user initiation, processor implements digital control of analog circuitry; settings stored in non-volatile memory
  • Nulling Line Impedance Range: 120 to 350 ohms
