Notes:
• The TX-DS989 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.
