SETTING THE MINIMUM AND MAXIMUM VOLUME

To set the minimum and maximum volume levels, the supplied Header Shunt needs to be tted

to the header JP1 as per the following procedure. With the amplier running set the Master

Volume to the desired volume, and with the A 2280B remote wall plate connected make sure

the amplier has the desired volume range when adjusting the A 2280B wall plate.

To set the “Minimum Level” adjust the remote volume to the desired lower volume level. Now

t the header shunt to the Centre and the Right pins of JP1 for a minimum of one second and

then remove the header shunt. The minimum volume level should now be set.

To set the “Maximum Level” adjust the remote volume to the desired upper volume level. Now

t the header shunt to the Centre and the Left pins of JP1 for a minimum of one second and

then remove the header shunt. The maximum volume level should now be set.
