(Many high quality loudspeakers also offer two sets of connections on their
speakers. Generally, one set of the connections on the loudspeaker feeds the
portion of the speaker’s crossover network that supplies the woofer with its
signal; the other set of connections connects to the portion of the crossover that
supplies the rest of the speaker with the midrange and high frequencies.)
Although the binding posts on your Classé amplifier will accept bare wire
connections, we strongly recommend the use of high quality spade or hook
lugs, crimped and soldered onto the ends of your speaker wires. Using
high quality connectors will ensure that your speaker connections do not
gradually deteriorate from fraying and oxidizing bare wires. It also helps
prevent accidental short-circuits from poorly-terminated connections.
4 Classé CAN Bus Control Ports
These RJ-45 connectors are reserved for future control and
communication applications using Classé Audio’s implementation of the
Controller Area Network (CAN) Bus specification.
5 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.
