4.2
Input stages
In the basic configuration, one stereo quasi-differential and three (two in case of HPS
applications) single ended stereo inputs are available.
4.2.1
Quasi-differential stereo input (QD)
The QD input is implemented as a buffered quasi-differential stereo stage with 100 k
Ω input-
impedance at each input. The attenuation is fixed to -3 dB in order to adapt the incoming
signal level.
4.2.2
Single-ended stereo input (SE1, SE2, SE3/AC2IN)
The input impedance at each input is 100 k
Ω and the attenuation is fixed to -3dB for
incoming signals. The input for SE3 is also configurable as part of the interface for external
filters in HPS applications (AC2IN)
