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 35 Watts per 
channel to the speakers. This is the perfect way to add power to low-power 
distributed audio systems.

the volume control on the device to change the volume level in the 
speakers. Portable music players and TVs are often used as local source 
devices.
