Biquad ALO3 3-Line Phone Hybrid

ALO3 3-Line Phone Hybrid
  • Passive balanced interfacing
  • Variable High and low cut filters
  • Industry standard connectors
  • Superb audio separation
  • Externally adjustable R and C balance
  • Remote controllable
  • GPIO interfacing with mixing consoles

The Biquad Telephone ALO-3 3-line hybrid concept originates from many demands for a more sophisticated hybrid with more features.

The Telephone ALO-3 is an analog unit with digital control and features like ducking making intelligibility a lot better in broadcast. A large ring button enables you to to pick up the line from the unit itself or from your mixer when connected via its GPIO to the telephone Hybrid.

Both levels of receive and send can be adjusted to suit your requirements. Incoming signals can be tailored by the variable high and low cut signal while talking to people calling the station. A switchable ducking system reduces the incoming signal while talking to people calling the station.
