Hx1 & Hx2 Híbrida Digital Linha única e 2 Linhas – Telos

Híbridas Telefónicas Telos - Hx1 de linha única e Hx2 de duas linhas

Telos® Hx1 one-line and Hx2 two-line POTS telephone hybrids are the most advanced hybrids ever developed for use with analog phone lines. Hx hybrids contain advanced 3rd-generation Telos hybrids for superior audio quality; universal POTS interface features disconnect-signal detection, which works with Telco providers worldwide. Hx hybrids include unique features to make operators’ lives easier, such as Auto-Answer with selectable ring count, a switchable mic/line input, call screening and line- hold features, and front-panel send and receive audio metering. Audio sweetening tools include Telos Digital Dynamic EQ (DDEQ) and adjustable smart leveler, symmetrical wide-range AGC and noise gating by Omnia®, studio adaption and pitch shifter for use in open-speaker applications, and adjustable caller override.

  • Single (Hx1) or two-line (Hx2) capacity with standard analog I/O (1 each send and receive in/out for Hx1, 2 each for Hx2).
  • Convenient switchable mic/line input.
  • AES/EBU digital audio I/O option available at time of order, or as a field upgrade kit.
  • Our most advanced digital POTS hybrids ever, with DSP algorithms optimized for superior performance with today’s wide variety of incoming call types.
  • Front-panel send and receive audio metering.
  • Telos DDEQ (Digital Dynamic EQ) and adjustable smart-level AGC ensure spectrally consistent audio from call to call — even on notoriously tough cellular callers.
  • Excellent trans-hybrid loss of >55dB.
  • Smooth, proven, symmetrical wide-range AGC by the audio processing experts at Omnia Audio.
  • Studio adaptation and a subtle, inaudible pitch shifter to prevent feedback in open-speaker studio environments.
  • Precision adjustable caller override.
  • Analog I/O 24-bit A/D/A sample rate conversion, 20 dB headroom from +4 dBu nominal levels.
  • AES/EBU I/O sample rate converters accept 32, 44.1, and 48 KHz rates. Clock for outputs may be sourced from the AES inputs or internally-generated at 48 KHz.
  • Incredible dynamic range of > 92 db (analog in to analog out, studio loop mode,
    10 hz – 20 khz A-weighted)
  • Auto-Answer with selectable ring count and disconnect-signal detection.
  • Call screening and line-hold features.
