Learning Event 5:
USE PATCH PANELS
The patch panel contains receptacles for all inputs and outputs of the audio console except for
microphone inputs, intercom wiring, and monitor speaker outputs. Inputs normally used with specific
mixers are internally interconnected to eliminate complicated patching.
Patch panels provide for quick interconnection of equipment, standardization of plugs and
connectors and the reduction of control room wiring. A complete patching facility will greatly extend
the flexibility of the audio console.
The patch panel has a series of lug receptacles (in pairs) for both inputs and outputs. The top
row of receptacles are for the outputs of various pieces of equipment and sources while the bottom is for
inputs to different pots on the audio console and certain pieces of equipment.
a. Above each pair of plug receptacles are labels describing what the various outputs and inputs
are (fig 2-30).
