Connecting speakers
• To prevent damage to circuitry, never short-circuit the positive
(+) and negative (–) speaker wire.
• Be sure to connect the positive and negative cables for the
speakers properly. If they are mixed up, the left and right
signals will be reversed and the audio will sound unnatural.
• Connect speakers with an impedance between 6 Ω and 16 Ω.
Connecting speakers with an impedance less that 6 Ω may
damage the TX-DS494.
• Do not connect more than one speaker cable to one speaker
terminal. Doing so may damage the TX-DS494.
• When you are using only one speaker or when you wish to
listen to monaural (mono) sound, a single speaker should
never be connected in parallel to both the right and left-
channel terminals simultaneously.
Connecting a subwoofer
Use the SUB WOOFER PRE OUT jack to connect a subwoofer
with a built-in power amplifier.
If your subwoofer does not have a built-in amplifier, connect an
amplifier to the SUB WOOFER PRE OUT jack and the subwoofer
to the amplifier.
