Audio Connections

Input Connections

For each input channel there is a female XLR connector for analog inputs. There is also one female XLR for one 
stream (two channels) of AES3 digital audio. Note that only two channels of AES3 digital audio are available. The 
Dante permits more channels of Digital Audio inputs.

The HOT, or  + connection should be made to pin 2 of the XLR connector.
The COLD, or - connection should be made to pin 3 of the XLR connector.

Pin 1 of the XLR connectors is internally connected to the chassis. The shield of the input cable should always be 
connected Pin 1 of the XLR to ensure that EMC performance and regulations are met.
 

DynO (where applicable) & limiters

Dynamic Optimization, which maximizes the output of every passband. This tangibly 

increases output over what would otherwise be possible.

Air Loss Pre-emphasis Filter

A distance, temperature and humidity-dependent air loss pre-emphasis filter 

improves high frequency projection by correcting for expected air losses  

for longer distances.

Easy Configuration

Just enter the loudspeaker model and amplifier you are using in the Greybox setup 

window.  Resolution automatically applies the Greybox settings and optimizes the 

entire system in seconds.
