Connecting speakers
Notes:
• The TX-DS787 is designed to produce optimum sound quality
when speakers with impedances within the specified ranges
are connected. Check the following information and choose
speakers with appropriate impedances for the connections.
CAUTION:
SPEAKER IMPEDANCE
6 Ω min. per each speaker terminal.
• 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.
• 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 and 16 Ω.
Connecting speakers with an impedance less that 6 Ω may
damage the TX-DS787.
• Do not connect more than one speaker cable to one speaker
terminal. Doing so may damage the TX-DS787.
