router acts as a full audio cross point: each of the 32 output channels (16 embedded AES, 16 discrete
AES) can receive signal from any one of the 41 (16 embedded AES, 16 discrete AES, 8 Analog, 1
silence) input channels. Each output also allows gain adjustment and optional polarity inversion.
The UDC-161 features a scaler card which provides the up, down, and cross conversion using de-
interlacing and motion adaptation for high quality up conversions. The scaler also provides user
adjustable aspect ratio control and zoom control. Separate controls are provided for SD and HD inputs
to allow the card to flexible handle mixed input formats.
Audio rates are always 48kHz nominally but discrete AES inputs pass through sample rate converters
to align them with the output timing. The sample rate converters can be disabled if necessary. Output
AES is always precisely locked in time with the output video. Analog audio is differential input and
sampled at 48 kHz with 0 dbFS digital equivalent to a +24 dBu analog.
The product also provides full color processing control of the output video, with separate controls for
Luma Gain, Luma Lift, Chroma Saturation and Color Phase.
All card configuration is done with a simple front panel menu. There is a four character text display to
view and control parameters, and a toggle switch and two buttons to navigate the menu.
The input and outputs of the UDC-161 are the following:
Input:
 One dual-rate HD/SD-SDI video input
 One 3-BNC dual-rate HD/SD analog video input
 4 dedicated AES input connections (AES input 5-6)
 8 differential analog audio inputs
Switchable Input/Outputs:
 4 AES connections, switchable between input and output (AES input/output 1-4)
Outputs:
 Two dual-rate HD/SD-SDI video outputs
 8 dedicated AES output connections. (AES output 1-8)
