4 Classé CAN-Bus Control Ports
ese RJ-45 connectors are reserved for control and communication
applications using a Classé implementation of the Controller Area
Network (CAN) Bus specication. Refer to the CAN-Bus section located
later in this manual for more information.
5 IR Input and Output
Your Classé amplier includes two

th
-inch mini mono-jacks in order to
support the IR remote controls that are ubiquitous today. IR commands
exist for toggling the amplier between operate and standby, as well as
discrete command codes for either operate or standby. ese codes may be
used in “macros” for sophisticated remote control systems, facilitating the
control of the amplier in the larger context of a complete system.
Actually, this IR Input and Output description is a bit of a misnomer: the
input supplied to these plugs is electrical in nature, not IR. It is obtained by
using standard IR receivers, distribution ampliers, and emitters (available
from your dealer) to translate the remote’s ashes of infrared light into
corresponding pulses of electricity. e big advantages here include being
able to easily route the signals anywhere they might need to go, and the
reliability of a solid electrical connection.
Since an IR distribution system such as your dealer may design for you
usually must control many products, your amplier includes both an IR
input (for the control of this product) and an IR output (so as to pass
along the same signal to the next product). is allows you to “daisy chain”
your control wires from one product to the next.
e amplier is designed to respond to IR commands of 5 Volts DC, with
the tip of the mini-plugs dened to be “positive” relative to the shank of
the plug.
6 DC Trigger Input and Output
Many audio/video preampliers can supply a DC control voltage to
associated equipment in order to induce desired behavior. Your Classé
amplier can take advantage of these capabilities in order to be switched
between operate and standby automatically, perhaps in concert with the
preamp/processor itself.

th
-inch mini mono-jacks provide this remote-controlled turn-on
(that is, toggling between operate and standby) of the amplier. ese jacks
provide a simple pass-through of the control voltage from one to the other,
allowing you to “daisy-chain” a series of ampliers quite easily.
e remote trigger will be operated by the presence of 5–12 Volts DC,
with tip polarity as shown below:
