Redback® 4 Channel Mixer With Bass & Treble
Redback® 1 Input / 2 Output Signal Splitter
10 year warranty This compact signal splitter is provided with two input sockets. The 3 pin XLR can be configured for either 3mV or 1V sensitivity, whilst the RCA auxiliary input can be set for either 100mV or 1V sensitivity. The input signal is split into two outputs. Each output is provided with two sockets. A 3 pin XLR with output adjustable to either 3mV or 1V and a dual RCA configurable to either 100mV or 1V. This enables the user to select a number of input to output signal configurations to suit their application. All input/output sensitivity adjustments are by DIP switches. Volume controls are provided for each output. The unit operates from an external 24V DC source. Features • 1 input to 2 outputs • Adjustable input and output signals • Individual volume controls for each output • Compact design, 25H x 105W x 81D mm • Internally selectable phantom power available on XLR input • 24V DC operation

Redback® Mic/Line/100V Input to Line & 24V Switched Output
10 year warranty Designed to meet the requirements of professional public address installations this mixer is ideally suited for use in shopping centres, gymnasiums, places of worship, court rooms etc. All inputs are configurable for balanced mic or line level input. The line level inputs are dual RCAs with DIP switch adjustable input sensitivity, and are internally mixed to give a mono signal. The balanced mic inputs are connected via 3 way euro blocks and have DIP switch selectable input sensitivity and selectable phantom power of 15V DC . A 1V balanced output is provided via euro blocks. The front panel includes individual volume controls and tamper proof, screw driver adjust, treble and bass controls for each input channel. There are two levels of priority/VOX muting. Inputs 1 and 2 will operate the priority/VOX muting regardless of the input configuration. (ie: both the microphone and line inputs will operate the priority/VOX circuit if this function is selected “ON” for that input). This is particularly useful when an input is set for line use, as it enables telephone paging, radio microphones, emergency tones or similar to mute background music on other inputs. Features • 4 inputs • Individual treble and bass for each channel • All mic inputs are balanced via 3 pin screw terminal blocks • All auxiliary inputs use dual RCA sockets • Adjustable VOX sensitivity • Record out socket dual RCA • Selectable input priority • Selectable phantom power • Selectable mic or auxiliary mute function • 24V DC plugpack included Price Each

The A 4906 is a versatile unit which accepts either a line level signal, balanced microphone signal or 100V input signal. The output signal is a line level signal suitable for feeding into an amplifier. Phantom power is available to the microphone input, and a VOX circuit, with adjustable sensitivity is used to trigger output relays. The unit is powered from a 24V DC source. Size: 133W x 30H x 80Dmm.

Redback® 100V Line To Mic / Line Attenuator 10 year warranty 10 year warranty This useful adaptor receives a 100V signal from one amplifier and reduces the level down to either balanced mic level or line level to feed into the input of a second amplifier. Especially useful for expanding existing systems where additional amplifiers are being installed away from the signal source. This revised version adds an additional XLR output socket with a high level output. Features • Volume control • Screw terminals for 100V input • 3 pin XLR mic socket • 2 x RCA line input socket • Requires no power • Minimal loading or signal loss • Balanced or unbalanced output
This four channel 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. 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. 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.
