Audio Connections The MixWizard uses professional grade 3 pin XLR and 1/4" TRS (3 pole) jack sockets. To ensure best performance, we recommend that you use high quality audio cables and connectors, and take time to check for reliable and accurate cable assembly. It is well known that most audio system problems are due to faulty or sub standard interconnecting leads.

SEND RETURN INSERT CHANNEL INSERT A single 3-pole TRS jack carries the unbalanced TIP RING insert signal. Tip = send, Ring = return, Sleeve = common ground. The channel insert is post-HPF, pre-EQ and operates at 0dBu. Use these to patch in line level signal processing equipment such as compressors, gates or outboard EQ. The wiring of a suitable cable is shown in the diagram: MIX INSERT Each mix is provided with an insert socket for patching in an outboard signal processor.
The Input Channels +48V Switches +48VDC to the channel input XLR for powering microphones or DI boxes that need phantom power. The power is current limited through 6k8 ohm resistors to pins 2 and 3. +48V PAD (LINE) 0 20 30 40 GAIN G 50 - 10 10 60 40 WARNING: Do not connect unbalanced sources or cables to inputs with phantom power selected. To avoid loud clicks always mute the channel before switching +48V on or off and when plugging or unplugging microphones.
MIX SENDS These rotary controls adjust how much channel signal +48V PAD (LINE) 0 20 30 40 GAIN G 50 - 10 10 60 40 is sent to the 12 mix outputs. Each has its own control. They adjusts from fully off to +6dB boost. Unity gain 0dB is marked at 3 o’clock position.
The Mix Masters MUTE Turns off the mix output. Affects the meter but does not affect the mix AFL function. This means you can mute the output while checking the post-fade mix signal using the console headphones and engineer’s monitor output. AFL Listen to the mix output in mono or stereo. Routes the postfade, pre-mute mix output to the engineer’s monitor system. The yellow LED lights when AFL is selected.
The Engineer’s Monitor The console provides left and right engineer’s monitor outputs on XLR and TRS jacks. The monitor signal is also fed to a built-in headphone amplifier with ¼” and 3.5mm output jacks. An AFL (after fade listen) function is provided to monitor the mix output signal. This is interrupted by pressing a channel PFL (pre fade listen) switch. An external input lets the engineer add an external stereo signal such as in-ear transmitter monitor output or talkback feed to the AFL mix.
Gain Structure How the levels between the different signal stages are set up is referred to as the gain structure. For best performance it is important that the connected source signals are matched to the ‘normal operating level’ of the console. Similarly the levels of the connected amplifiers and destination equipment should be correctly matched to the console outputs.
