A0302... Speaker to
Line-Level Converter
The A0302 can
convert the speaker-
leveloutput of an audio
amplifier to a line-level
output that can be
used to drive the
A0240.

Using the A0240 as a local input amplifier
In addition to increasing power of a distributed audio system, the A0240 can
also be used to interrupt a the whole house audio source and amplify a local
source device.
Using the A0240 with the A0302
The A0302 is the perfect complement to Channel Vision’s A0240 amplifier. It
can utilize the Amp-Link connection, which provides a clean way to interrupt
the speaker-level audio from a low-power system and output 40 Watts per
channel to the speakers. This is the perfect way to add power to low-power
distributed audio systems.
