6 Balanced (XLR) input
These XLR jacks accept right-channel and left-channel balanced signals
from a source component with balanced outputs. This input may be
selected by touching the corresponding button on the main operational
screen of the front panel touchscreen.
The pin assignments of the XLR input connectors are:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
These pin assignments are consistent with the standard adopted by the
Audio Engineering Society (AES14-1992).
Refer to the operating manuals of your balanced-output line-level source to
verify that the pin assignments of its output connectors correspond to the
CAP-2100. If this is not the case, wire the cables so that the appropriate
output pin connects to the equivalent input pin.
To achieve the best possible results, we suggest that you use only high-
quality interconnect cables. Please consult with your local Classé dealer for
advice on the best cables for use in your system.
7 IR Input and Output
Your Classé integrated amplifier includes two 1/8th-inch mono mini-jacks
in order to support the infrared (IR) remote controls that are ubiquitous
today. Infrared commands exist (for example) for toggling the integrated
amplifier between operate and standby, in addition to 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
integrated amplifier in the larger context of a complete system.
The list of commands available is quite extensive, enabling even complex
macros (chains of commands strung together) to operate flawlessly. 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. They are used
with standard IR receivers, distribution amplifiers, and emitters (available
from your dealer) to translate the remote's IR signal to an electrical signal
and vice versa. 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 integrated 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.
