The Redback® A 4933 accepts either a microphone level, line level, music or bluetooth input and converts the signal to a balanced high level output. The high level output signal is carried via Cat5e/6 cable, (suitable for distribution up to 200m without interference) back to Redback® compatible devices such as the Redback® A 4930 Hub, Redback® A 4942, Redback® A 4946 or Redback® A 4495 Source selector wall plate.
Microphone inputs are balanced XLR inputs, while the Line input is via 2 x RCA sockets, or 3.5mm audio jack for portable devices. A bluetooth receiver offers the ability to interface Bluetooth audio devices.
VOX muting is available which mutes the AUX, Music and Bluetooth inputs when any microphone input is active. The VOX sensitivity is adjustable via the front of the wallplate.
All wall plates assembled by Altronics are supplied with two facia clip on covers. These are designed to match your current decor. Simply clip on the desired cover after installation.
