Input Configuration
All Input configuration settings can be found in the Basic tab on the Input screen.
If not there already, touch the ADJ icon button (if you are still in the Setup mode) and then the Input icon button to
display the basic Input screen.
This is where you choose your input source, failover source, set input levels, input mode and overall polarity.
If you have not done so already, the instructions for properly setting the input levels can be found in Chapter 2 on
Page 12. Input levels can be adjusted separately for Analog, AES/EBU and Livewire inputs.
The Input Mode drop-down control allows you to select from Stereo (the default setting), Mono L (routes the left
channel input signal to both the left and right processing channels), Mono R (same as Mono L but uses the right
channel input signal), Mono L+R (sums the left and right input channels to mono and applies the summed signal to
both channels) and Swap (Stereo but with the left and right channels reversed)
The Input Polarity drop-down control allows you to change the polarity of the input audio in several ways. Both is
typically selected if it sounds “better” to an announcer (monitoring themselves in headphones using the DJ output of
the processing) than None. One of the two settings should. The goal is to make the relative phase of the headphone
feed more in phase with the announcer’s hearing of his or her own bone conduction. Once set, this setting should
remain the same for all announcers using the same headphone feed.
Using the L setting, only the left channel phase is inverted and using the R setting, only the right channel phase is
inverted. NOTE: These settings are present as a convenience to correct 180-degree stereo phase errors in the input
audio to the processor or in another device after the processor.
You can choose from among 4 possible stereo input sources for both the primary and secondary sources: Analog,
AES/EBU Digital, Livewire 1 and Livewire 2.
The Primary input source is set using the Input Source drop-down control.
