The LSA40 Local Source Amplifier
The LSA40 is highly versatile , 40 watt stereo amplifier designed to be installed in a single gang low voltage ring. An audio
sensing feature allows the LSA40 to automatically amplify any incoming line-level audio signal. As described in fig. 13, the
LSA40 can be connected to the Simplese keypad allowing use with a local source or an incoming NuVo system source through
a common pair of speakers in any zone.

A two conductor wire is used as a voltage trigger from
the LSA40 the NuVo zone keypad. When the zone is
turned on this allows to NuVo system audio to pass to
the zone speakers. When the zone is turned off the
internal amplifier of the LSA40 is automatically
engaged.
The connection from the LSA40 to the
Simplese keypads is done using a green two
pin screw down terminal.
