Connecting Speakers
Before you connect your speakers, read the following:
• Disconnect the power cord from the wall outlet.
• Read the instructions supplied with your speakers.
• Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive
(+) terminals, and negative (–) terminals only to nega-
tive (–) terminals. If you get them the wrong way
around, the sound will be out of phase and will sound
odd.
• Only use speakers with an impedance of between 6
and 16 ohms. If you use speakers with a lower imped-
ance, and use the amplifier at high volume levels for a
long period of time, the built-in protection circuit may
be activated.
• Unnecessarily long or very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the posi-
tive and negative connections.
Doing so may damage the
TX-L55.
• Don’t connect more than one
cable to each speaker terminal.
Doing so may damage the
TX-L55.
• If you want to connect a single speaker instead of a
pair, connect it to either the left or right speaker termi-
nals, not both.
Attaching the Speaker Labels
The TX-L55’s positive (+) speaker terminals are color-
coded for ease of identification. (The negative (–)
speaker terminals are all black.)
The supplied speaker labels are also color-coded and you
should attach them to the positive (+) side of each
speaker cable in accordance with the above table.

bare wires, not the insulation.
