INTRODUCTION
Congratulations on purchasing the Weiss Gambit Series ADC2 A/D Converter !
The ADC2 is a two channel A/D converter designed for
most demanding audio applications. It uses state of
the art A/D chips in Weiss Engineering’s proven “corre-
lation technique” configuration, which lowers con-
verter imperfections and improves the SNR ratio.
For best noise rejection, the analogue input signal is
kept balanced from the input connectors up to the
converter chips. A high quality microphone preamp is
available as a standard feature.
Additionally, there is a built-in digital two-segment
compressor / limiter for optimal levelling, employing
adaptive release timing, look-ahead circuitry and
sidechain-oversampling for mastering-quality dynam-
ics processing.
Large bar graphs, a well thought-out push button
array and uncluttered rotary knobs optimize handling
ergonomics.
Summary of ADC2 features:
Inputs
•
Two balanced LINE and two MIC inputs on sepa-
rate XLR connectors.
•
MIC input with switchable phantom power.
•
Input sensitivity is settable in each channel inde-
pendently (or ganged) with two rotary encoders.
•
Line Input sensitivity: -16dBu to +26 dBu.
•
Mic Input sensitivity: -54dBu to +6dBu.
•
Separate AES/EBU input on XLR for synchroniza-
tion and/or audio input to the DSP, which allows
for use of the ADC2 for redithering and limiting of
digital signals.
Synchronization
•
Internal sync selectable 44.1kHz, 48kHz, 88.2kHz,
96kHz, 176.4kHz, 192kHz.
•
External sync from Wordsync Input (BNC) or from
AES/EBU input.
•
Wordsync output on a BNC connector.
Metering
•
One input / output level bargraph per channel
with short peak hold
•
One gain reduction bargraph per channel.
•
Two over LEDs
•
Two numerical displays for peak hold and level
settings.
•
Reference for level setting can be altered
