Connecting Your Loudspeakers

Choosing a speaker cable
There are many types of loudspeaker cable available which are suitable
to partner Cyrus speakers. We make general recommendations to choose
a cable which is simple in construction and which is made with high
quality materials for the conductors and insulation. A good dealer will be
able to advise a suitable cable and provide the correct terminations for the
amplifier and speakers.
Phasing
Correct phasing is essential when connecting a speaker to an amplifier.
All amplifiers and speakers are equipped with + (or red) and – (or black)
terminals for connection of the speaker cables. For the speaker system to
work correctly the + and – output terminals of the amplifier must connect
to the corresponding + and – terminals of the speaker. All speaker cables
have a polarity mark (plastic rib, coloured stripe or + markings) on one of
the wires. This wire is the + wire and should be connected to the
corresponding + terminals of both the amplifier and speaker.
Cable directionality
Most speaker cables are sensitive to the direction of signal flow. If so, the
cable will be marked with arrows which should point in the direction of the
signal (from amplifier to speaker).
Connecting cables with tags to the speakers
Unscrew the four terminal tops so that the tags can be tucked underneath.
Tighten the terminal tops securely to retain the tags.
Connecting cables without tags to the speakers
If the cables don't have connection tags fitted they must first be stripped
as shown in the diagram below. The stripped ends can then be twisted
together and fitted into the hole drilled in the terminal pin.

Bi-wiring and Bi-amping

Bi-wiring
Cyrus speakers are designed to be used with bi-wired or bi-amped wiring
arrangements. Two cables (or a bi-wired pair) are necessary to connect
each speaker to the output terminals of your amplifier. Most Cyrus
amplifiers feature twin speaker outlets for the most effective bi-wiring
connection as shown in the schematic below.

LF
NOTE:- Any bi-wire links must be removed from the terminal panel when
the speakers are connected to a bi-wired system.
Bi-amping
The benefits of bi-wiring can be further extended with the addition of
separate amplification for the bass and tweeter units of your speakers (bi-
amping). In this case the preamplifier output of the Integrated amplifier is
connected to the input of a power amplifier and separate connections are
made from the speaker outputs of each amplifier to the speaker drive
units. Bi-amplified wiring of a Cyrus amplifier is simple and is shown in the
schematic.
NOTE:- Any bi-wire links must be removed from the terminal panel when
the speakers are connected to a bi-amplified system.
Removing the bi-wire links
If the speakers are to be used in a bi-wired or bi-amplified system it is
essential to remove any bi-wire links from the terminal panel. To remove
the links unscrew all four terminals. The links can then be removed from
the terminal panel as shown in the diagrams below. The four connection
wires can then be fitted to the terminals.
