Connecting speakers
Notes about speaker cables
o Use commercially-available speaker cables to connect the speakers.
o Use the shortest speaker cables possible. The longer the cable, the
greater the resistance value and the more that damping performance is reduced. Moreover, length also increases impedance and
capacitance, degrading the sound quality of high frequencies.
o Use left and right speaker cables that have the same length.
How to connect speaker cables
Use commercially-available speaker cables to connect the + terminal
of the unit to the + terminal of the speaker and the − terminal of the
unit to the − terminal of the speaker.
o Use speakers with at least 4 Ω impedance.
o If the exposed tip of the core wire of a speaker cable contacts
another cord or terminal, a short could occur.
Never allow a speaker cable to short.
o Do not connect more than one amplifier to a speaker.
o Do not bundle connecting cables with power cords. Doing so
could cause noise.
V
The power plug should always be disconnected
when connecting speaker cables.
When using bare wires
Loosen the cap, insert the core wire from above and tighten the cap.
o The insertion hole faces up.
Cross-section
o The maximum wire diameter that can be inserted is 4 mm (1/8”).
When using spade lugs
Loosen the cap, place the lug around the terminal from above or
below and tighten the cap.
When using banana plugs
Insert the plug into the opening in the end of the terminal.
o Keep the cap tightened when using.
o Carefully read the instructions for the banana plugs that you are
using.
Notice about the European model
In accordance with European safety regulations, connecting
banana plugs to speaker terminals is not allowed on European
models.
The holes into which banana plugs could be inserted have been
covered with black caps. Connect speakers using bare wires or
spade lugs.
If a black cap should become separated from its terminal, return it
to its original position.
o When using a spade lug to connect, use one with an inside diam-
eter of at least 6 mm (1/4").
