1—SI-AD4 Input Module
Each SI-AD4 Input Module provides four balanced input jacks with female XLR connectors. Each input
has a variable gain XR-1 preamp that accepts signals from -65 to +10 dBu (+28 dBu maximum).
Additionally, there are three status indicators for each input:
•
+48V—lights orange when +48V phantom power is supplied from the channel.
•
CLIP—lights red when the input signal exceeds 0 dB (after A/D conversion).
•
SIG—lights green when the input signal is greater than -40 dB (after A/D conversion).
The S-4000S includes eight SI-AD4 Input Modules, providing a total of 32 input channels.
Preamp gain adjustment and phantom power status can be controlled from the S-4000R Remote
Controller or from a computer using the S-4000 RCS.
