Audio Authority 1109A AVAtrix Cat5 Control Bridge

ITEM: 1109A

  • Inject IR signals into Cat 5 zone wiring
  • Send IR upstream to AVAtrix and sources
  • Send IR downstream to control TVs


The Model 1109A Cat 5 Control Bridge provides an access point for control systems to use the AVAtrix Cat 5 infrastructure, reducing wire, installation labor, and programming code. There are two main applications for the 1109A: controlling TVs (on/off, change inputs, etc) and switching/controlling sources. These applications can be used independently or together, for each zone, upstream and/or downstream from the 1109A.

The 1109A IR jacks are isolated from all other system wiring and can therefore be used for any kind of low speed signal suited for Category 5 cable conductors. The Model 1109A is compatible with all of our dual Cat 5 zone receivers, including Models 9878, 9879 and 9880. Each Cat 5 receiver IR pathway operates independently, so one pathway could be set up for in-coming IR signals and another pathway in the same system could be set up for out-going IR signals.

  • Send IR signals upstream, downstream, or both directions
  • Passive device - requires no power connection
  • Interrupts AVAtrix 12 volt power rail for safe operation using standard 3.5mm patch cables
  • Use multiple 1109As for large AVAtrix systems
  • Designed and manufactured in Lexington, Kentucky, USA


Q: How is the 1109A different from the 1109?
The 1109A combines all the functionality of the 1109 and the 1111 in one unit, so IR signals can be sent upstream and/or downstream on the Cat 5 zone wires.

Q: Can control signals be injected both upstream and downstream on the same Cat 5 zone pathway?
Yes, starting at the 1109A, different IR signals may be sent in either direction on the same zone pathway. This configuration is illustrated in the 1109A manual.

Q: Can I send other types of signals through the 1109A?
The Model 1109A is not recommended for currents more than 200mA.
