The channel CONFIG button:
Please note: Some settings can only change when fader is closed
!
For input 1 – 6 you can select between MIC, LINE A and LINE B. For input 7 and 8 this is AES/EBU,
LINE A and LINE B. The functions of the other boxes are:
With ‘Type’ you will set the logic behavior of the channel:
‘CR microphone’, Monitor speaker will MUTE or DIM upon opening of this channel fader as well as
activate the CR red-light.
‘Studio microphone’, Studio monitor will DIM upon opening of this channel fader as well as activate
the STUDIO red-light.
The amount of DIM can be set in the SYSTEM setting. Also a line input can behave as a microphone
input in case you are using an external microphone processor.
‘Hybrid’ In case you connect a telephone hybrid to this input. It will reveal the yellow telephone icon
in the ‘select’ mode of the channel offering the possibility to switch a hybrid on and off hook as well as
a DTMF keypad to dial a telephone number.
In case you are using another type of communication device or a telephone system that does not
need or support the Telco switching or dialing you can set the channel as ‘Line input”.
‘Config’: Can be ‘stereo’, ‘swapped L+R’, Left to mono, Right to mono, mono to both. Although
displayed this is not active in MIC mode.
‘HPF’ the frequency of the high-pass filter can be set.
‘TB output’, if needed an aux output can be coupled to this input for Talkback purposes. E.g. a feed to
a presenter headphone or TB to a hybrid or other “Outside Source”. If set this will display the green
TalkBack” button in PFL mode. Note: if mixed PFL is used Talkback becomes active for all channels in
PFL mode that have an AUX coupled to them!
Check boxes INV L and INV R: phase reverse function. To reverse the phase of a microphone select
both. Careful: Left or Right phase reversed and input ‘Config’ in mono will cancel the signal!
Only in MIC Mode: 48 V PHANTOM power switch. Although present in each MIC input screen the 48V
phantom powering is centrally switched for all microphones inputs!
Check boxes MAIN A and MAIN B: Selects the main output for the channel signal. The corresponding
LED next to the fader will light; green with fader closed and this will turn red upon opening of the
fader. A red LED also indicates if a signal is routed to an output in the event a fader is externally
overruled.
The third LED next to each input fader marked “O” is input overload indication.
