Notes:
  1. Digital Hybrid Wireless™ technology negates the need for compandors or their artifacts.
  2. Digital Hybrid Wireless™ systems can emulate all Lectrosonics wireless analog components, including IFB, plus many wireless analog components from other vendors. (Call Lectrosonics for more details.)
  3. 25 KHz spacing is available in Europe through authorized Lectrosonics Service Centers. Contact our sales staff for more details.
  4. Dynamic Mic: 300 Ohms
    Electret Lavaliere: Virtual Ground with servo adjusted contant current bias
    Line Level: 2.7 kOhms
  5. If set for dynamic mic: 0.5 mV to 50 mV before limiting; greater than 1 V with limiting.
    If set for electret lavalier: 1.7 uA to 170 uA before limiting; freater than 5000 uA (5 mA) with limiting.
    Line Level: 5.0 mV to 500 mV (0.5 V) befroe limiting; greater than 15 V with limiting.
  6. Depending on the Compatibility Mode selected, Digital Hybrid Wireless (400 Series) transmitters can produce pilot tones for other Digital Hybrid Wireless (400 Series) systems, or 200 Series analog systems.
  7. The digital encryption key is used to control the receiver, thus negating the need for a pilot tone
