TWO WAY RS 232
FOR CONTROL FROM ANY AMX®,
OR CRESTRON®, AURORA WACI®
CONTROLLERS OR OTHER DEVICES
The Amplifier's Volume is controlled through the RS 232 Two Way Control Port. The Front
Volume Level Trim Pots control the actual (or Total Amount) of Output Level of each
Channel. For Example: Setting the Front Trim Pots to 50% will provide 50% Output from the
RS 232 Internal Digital Pots. So for 100% RS 232 Volume, make sure the Front Trim Pots
are set some where near Maximum (turned clockwise).
