15 IR INPUT

panel provides direct access to the infrared control circuitry of the AVP . It
may be configured during setup (in an on screen menu) to interpret in-
coming signals in either of two ways:
• Remote : when in Remote mode, the AVP will interpret any com-
mand entering through the remote IR jack as being intended to
affect the
record/remote path
cess to all sources connected to the AVP from elsewhere in the
house with the addition of any commercially-available IR repeater.
: when in the Local mode the remote IR jack responds to
• Local
all commands, as the infrared receiver in the main display of the
front panel would. This mode is most often used with an IR re-
peater when the AVP and other components are placed inside of
cabinets (preventing the normal IR receiver from receiving remote
commands). (See The Setup Menu.)
The incoming signal for the remote IR input should conform to widely-ac-
cepted IR repeater standards: that is, the signal present should be between
3-15 volts DC at less than 100 mA current, with a positive tip polarity , as
shown below:

16 DC TRIGGERS
Each of the two remote on/off triggers can be configured by your installer
to provide either 5V or 12V DC trigger signals, either in response to the AVP
coming out of
standby
. The tip polarity for each of these triggers is as shown below:

These triggers provide some degree of control and automation over prod-
ucts that lack more sophisticated communications capabilities. For example,
you could have one of these triggers toggle your amplifier(s) on and off ac-
cording to the operational status of the AVP , while the other served to lower
the screen for your projection television when a particular IR command was
received.
