Front, rear and center speakers can be connected to this unit.
Speaker impedance and power capability
This receiver is designed to work best with speakers having
nominal impedance from 8 to 16 ohms. Be sure to use a
speaker system with adequate nominal impedance and
power handling capabilities.
When using two center speakers, use the speakers having
nominal impedance from 4 to 16 ohms.
Also, use all speakers to be connected with the equal
efficiency.
Note
When connecting the speaker cord to the speaker terminal,
make sure that the polarity (+ and -) of the speaker cord is
correct. If the polarity is reversed at either speaker, the
sound will be distorted and will lack bass.
