Classé CAN-Bus Control Ports
These
RJ-45
connectors are reserved for control and communication
applications using a Classé implementation of the Controller Area
Network (CAN) Bus specification. Refer to the
CAN-Bus
section located
later in this manual for more information.

IR Input and Output
Your Classé amplifier includes two
1
/
8th
-inch
mini mono-jacks
in order to
support the IR remote controls that are ubiquitous today. IR commands
exist for toggling the amplifier between
operate
and
standby
, as well as
discrete command codes for either
operate
or
standby
. These codes may be
used in “macros” for sophisticated remote control systems, facilitating the
control of the amplifier 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 amplifiers, and emitters (available
from your dealer) to translate the remote’s flashes of infrared light into
corresponding pulses of electricity. The 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 amplifier 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). This allows you to “daisy chain”
your control wires from one product to the next.
The amplifier is designed to respond to IR commands of 5 Volts DC, with
the tip of the mini-plugs defined to be “positive” relative to the shank of
the plug.

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

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