Functionality
2.1 Audio input
The control pad contains an input matrix which allows the connection of the following sources:
•
2 x MIC (microphone)
•
2 x LINE
•
1 x TV / Tuner
•
1 x AV / AUX
•
1 x AWS (PCX card)
•
1 x TEL (external telephone hybrid)
•
1 x ISDN (external ISDN codec)
•
1 x INSERT
All inputs have adjustable input-level controllers which can be controlled via the PC software so that
the signal level can be adjusted individually prior to the A/D convertion.
Both
MIC
inputs (MIC1 / MIC2) are symmetrical mono inputs using XLR connectors with input
transformer. 48V phantom power is switchable. Input sensitivity can be adjusted within 0,5 dB steps
from -20..-80 dBu.
Both
LINE
inputs are configured as stereo sources and can handle symmetrical and asymmetrical
signals. There are 2 XLR jacks for the symmetrical configuration and 2 cinch jacks each for the
asymmetrical. The symmetrical and asymmetrical inputs are passively mixed but are actively de-
coupled to allow concurrent use.
TV / TUNER a
nd
AV / AUX
inputs are each configured as stereo sources, each with 2 XLR
connectors.
The audio workstation input (
AWS / PCX
) is also configured as a symmetrical stereo source (analog),
but uses a 15-pin sub-D connector for directly connecting to a PCX card (including return path to audio
input of PCX board).
The
TELEPHONE
input is for connecting an analog telephone hybrid and is configured as a mono
source. It uses a 15pin sub-D connector and contains both the return channel and external control
signal for activation.
For connecting an
ISDN
codec a separate symmetrical stereo input is provided, which also uses a sub-
D connector connector (including return signal and control signal as well).
The
INSERT
input is provided so that effects devices or signal processors (e.g. voice processors) can
be switched in. It is configured as a symmetrical stereo input with a 15-pin sub-D connector. The
connector also contains the necessary INSERT SEND output.
All of the symmetrical inputs are electronically balanced, with the exception of the two transformer
symmetrical microphone inputs. The input sensitivity can be set in 0.5 dB steps b24..-10 dBu.
