RS-232 Control Port
Th
is DB-9 connector has two purposes:
• downloading new operating software into your preamplifi er
(should new features ever be added, for example)
• external control of your preamplifi er by control systems such as
i-Command
™
, AMX
®
and Crestron
™
For more information, please contact your dealer and ask about home
automation systems.

Classé CAN-Bus Control Ports
Th
ese RJ-45 connectors are reserved for future control and communication
applications using Classé Audio’s implementation of the Controller Area
Network (CAN) Bus specifi cation.
10 IR Input and Output
Your Classé preamplifi er includes two 1/8th-inch mini mono-jacks in
order to support the infrared (IR) remote controls that are ubiquitous
today. Infrared commands exist (for example) for toggling the preamplifi er
between operate and standby, in addition to 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
preamplifi er in the larger context of a complete system.
Th
e list of commands available is quite extensive, enabling even complex
macros (chains of commands strung together) to operate fl awlessly. If this
capability is of interest to you, we strongly recommend discussing it with
your authorized Classé dealer.
Note that IR Input and Output is a bit of a misnomer: the input and
output of these plugs is electrical in nature, not infrared. Th
ey are used
with standard IR receivers, distribution amplifi ers, and emitters (available
from your dealer) to translate the remote’s IR signal to an electrical signal
and vice versa. 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 preamplifi 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 preamplifi er is designed to respond to IR commands of 5 Volts DC,
with the tip of the mini-plug defi ned to be positive relative to the shank of
the plug.
