B&K AV100.2 User Manual - Control Triggers

Control Triggers
A control (trigger) system is provided on the AV brick amplifiers to allow re-
mote switching of the amplifier’s standby on/off feature. The control input is
designed to operate with a source (trigger) of at least 4VDC (less than 1mA).
The signal sent from the control output is +5VDC (up to 50 mA) to trigger
other devices.
The control trigger is also sent through the RJ-45 connection when connecting
multiple AV amplifiers. When using any control trigger to send the unit into
standby state (from minijack or RJ-45 connection) the CTRL I/O dip switch
has to be enabled. The status light on the back of the AV brick amplifiers will
turn off when the amplifier is in standby state. All B&K A/V receivers and
preamplifiers utilize control output triggers to easily integrate an amplifier into
an audio system.
Shown below is an AV amplifier receiving signal and control output from
Zone B on a Reference 50. It also shows the control output on the AV ampli-
fier being used to trigger another device. Please see Input and Output Connec-
tions through RJ-45 for more information on the RJ-45 connectivity.
Note: The control input voltage is intended for standby on/off control only. For
amplifier operation, each amplifier must have its own source of AC power.

device
When using the control in either from 1/8” minijack or RJ-45 connec-
tions, the DIP switch labeled CTRL IN MUST be enabled. Otherwise
the amplifier WILL NOT be looking for a 12V trigger.
