System Trigger Output Connection
When any zone of the AH66T is ON, +12VDC is present on the System Trigger Output. This
can be used to activate devices like power controllers or to un-mute amplifiers.

Zone Preamp Audio Outputs
Each zone of the AH66T has a corresponding Zone Preamp Output that is used to send
signals to auxiliary amplifiers-typically for sub-zone applications. Each zone’s audio is sent
out of both the Speaker Outputs and the Zone Preamp Outputs simultaneously. Use the
ATON configuration software to configure the Zone Preamp Output to FIXED or VARIABLE.
(Factory Default setting is VARIABLE)
FIXED zone pre-amp outputs are set to full volume at all times. Typically, FIXED subzones
have their own volume control in order to have independent volume Up/Down control and
will always share the source that the rest of the zone is playing.
VARIABLE zones ramp volume Up and Down using IR or serial commands sent from a
touchpad or hand-held remote. VARIABLE sub-zones share both source selection and
volume Up/Down functionality (all speakers ramp volume Up/Down simultaneously).
