your amplifier and/or speaker systems.
Speaker Impedance
When
speaker
systems
are connected
to only SPEAKERS
A or
SPEAKERS B terminals, such speakers should have rated impedance
in the range of 4-16 Q.
When speakers are connected to both the A and B terminals, they
should have a rated impedance in the range of 8-32 Q.
CONNECTING THE POWER CORD
Household electrical outlets are provided with specific polarity, a live
side and a neutral (ground) side. This unit utilizes such polarity in order
to improve sound quality. As shown in the illustration, be sure to insert
the power plug so that its blades match the width of slots in the outlet.
