1.3 Module connection and mounting
The module is supplied with a pre-wired 2.1mm power
connector. The centre pin is positive. The audio in and
out are pre-wired pairs of wires, ready to be connected
intheaudio path.Theheatsink doublesupas amounting
bracket.
This module is designed to be driven from a high level
signal, capable of driving a load of 22W.
(The module can be easily modified to be driven from a
low power signal, see section 3.3 for more information).
The module can be mounted
using the supplied self adhesive
foam pad. Ensure that none of
the circuit pins can make contact
with any metallic parts.For improved heat dissipation
and a more rigid mechanical
fixing the heatsink can be
reversed and used as a bracket.
Note that the heatsink is at 0V
potentialandthereforemayhave
to be electrically insulated from any other metallic parts.
Alternativelythemodulehasfour
fixing holes which allow it to be
fixed to pillars.
(See section 6 for hole details
and physical dimensions).
