Stereo Zones w/ Stereo Sub-Zone Using Volume Controls
Connect the Zone Preamp Output to a pair of the external amplifier’s inputs. Using the
ATON configuration software, configure the Zone Preamp Output to FIXED. Use an
impedance matching volume control (ATON AVC100R or AVC100SL) on the external
amplifier’s speaker outputs to maintain independent volume control capabilities in each
room. The main zone ramps volume up/down at preamp level using IR or RS-232
commands sent from an OLED2 Touchpad, or hand held remote, while the sub-zone ramps
volume up/down at speaker level using the volume control. This application uses one pair
of amplifier channels from the AH66T and one pair of amp channels from the external
amplifier. Many areas of the home are ideal for zone/sub-zone configuration. Examples
include Master Bedroom/Master Bath or Kitchen/Dining Area.
Figure 2-2 shows an example of stereo zones and a stereo sub-zone.
