The 32×4 analog audio router has 4 output (pairs):
Fig. 2-59: Rear View, 32×4 Analog Audio Router
Fig. 2-60: Top View, 2RU Analog Audio Router
Analog inputs are in the middle; analog outputs are at the top and bottom (in the dark regions).
Each DB25 connector supports 8 inputs (or outputs):
The 8 input connectors provide inputs 1–8, 9–16, 17–24, 25–32, 33–40, 41–48, 49–56, and 57–64,
respectively, and are labelled that way on the rear of the router. Inputs are treated as 32 stereo
pairs.
The same is true for the outputs.
The 2RU analog audio router also has a small fan.
