Redback 4 Input 3 Tier Priority Mixer

Redback 4 Input 3 Tier Priority Mixer

The Redback A5131 4 Input 3 Tier Priority Mixer features 4 balanced mic inputs and 3 line inputs. Input 1 is a dedicated balanced mic input whilst inputs 2 - 4 can accept either balanced mic or line level. Microphone connections are via 5-way pluggable euro block and line connections are via stereo RCA socket (converted to mono internally). Two outputs are provided, one for balanced output (level selectable 3mV or 1V) and one for line level.

The system can be configured for PTT muting which operates only with microphone inputs, or VOX muting which operates with both microphone and line inputs. Each input is equipped with a volume control and channel active LED indicator.

System Busy

Euro block terminals are included for remote LED indication that the system is busy. For the input in use the LED is in a steady illuminated state. For all other inputs the LED’s flash indicating the system is busy and in use. The corresponding LED on the front panel also illuminates indicating the active channel. The LED’s operate both with microhpne and auxilliary input signals with either the PTT or VOX muting options selected. The remote busy indicator voltage can be selected internally to 1.5V DC for driving LED’s direct ,or 12V DC for driving incandescent lamps.

Priorities

3 modes of priority are selectable via the DIP switch on the rear:
• Cascade: Input 1 overrides 2-4, Input 2 overrides 3-4, Input 3 overrides 4.
• FIBD: Regardless of which input is being used, it automatically blocks out all other inputs.
• None: No priority therefore all inputs will be mixed as per a normal mixer.

VOX sensitivity

The sensitivity of the VOX circuit can be adjusted via the trimpots located on the front of the unit. Each input has its own dedicated adustment trimpot. If the Vox circuit needs to be turned off for a particular input, turn the corresponding trimpot fully anti-clockwise.
