Classé CAN-Bus Control Ports
Th
ese
RJ-45
connectors are reserved for control and communication
applications using Classé Audio’s implementation of the Controller Area
Network (CAN) Bus specifi cation. Refer to the
CAN-Bus
section located
later in this manual for more information.

IR Input and Output
Your Classé amplifi er 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 amplifi er between
operate
and
standby
, as well as
discrete command codes for either
operate
or
standby
. Th
ese codes may be
used in “macros” for sophisticated remote control systems, facilitating the
control of the amplifi er 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 amplifi ers, and emitters (available
from your dealer) to translate the remote’s fl ashes of infrared light into
corresponding pulses of electricity. Th
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 amplifi er 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). Th
is allows you to “daisy chain”
your control wires from one product to the next.
Th
e amplifi er is designed to respond to IR commands of 5 Volts DC, with
the tip of the mini-plugs defi ned to be “positive” relative to the shank of
the plug.

DC Trigger Input and Output
Many audio/video preamplifi ers can supply a DC control voltage to
associated equipment in order to induce desired behavior. Your Classé
amplifi er can take advantage of these capabilities in order to be switched
between
operate
and
standby
automatically, perhaps in concert with the
A/V preamp itself.

th

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