Audio Module
Overview
Introduction
The Ponderosa Audio routing switcher is based upon a modular architecture of an
integrated frame, motherboard and backplane. Common input and crosspoint modules
are used. The same two types of modules are used for both frame sizes: 64x64 and
128x128.
There are two basic modules:
 Input Buffer Module
 Crosspoint/ Output driver Module
The 64x64 frame has positions for two 32-channel input buffer and two crosspoint/output
driver modules; and the 128x128 frame has positions for four 32-channel buffer modules
and four crosspoint/output driver modules.
All modules are front extractable and “hot-swappable”. The frame is force air cooled
using internal cooling fans contained within the front panel.
Note:
Although modules are “hot-swappable” it is advised that power be removed when removing or
inserting modules when possible.
