The MkII Version
The MkII version now adds the following as standard features:
- 48v phantom power
- upgraded input gain pot
- input gain range increased from -20 to +10 dB
- GPOs on Mic and talkback buttons to allow integration with main intercom or talkback system
VERSION 3 (TT): This version has transformer balanced inputs & outputs with high quality Llundhall transformers on the individual mic outputs.
Three front panel inputs are mic/line switchable with selectable 48v phantom power. The front panel also has a small gain adjustment pot. Mic on/off switches can be selected in on/off mode or in cough mode. There is a global low frequency cut that can be selected on or off, and a preset compressor/limiter per input.
Each input has a direct discrete output on the rear panel along with a mixed output of all of the inputs, all on XLR. The mixed output is also available on an un-balanced 3.5mm jack socket as a local record. The direct output levels can be set in 3 positions:
1: 0dB + limiter: This is the normal operation and it limits peak levels.
2: 0dB: This feeds the output with an un-compressed nominal level of 0dB, for when the peak signal level will be controlled by outboard equipment.
3: -20dB: This feeds the output with a nominal level of -20dB providing extra headroom.
There are 3 common talkback circuits with individual buttons on the two main commentators’ sections (Position B's input cannot be switched to a talkback output). The operation of the talkback buttons features Config+ for configuring in different modes.
