Notes
• Because the power amplifier of A-S1100 is of the floating balanced type, the
following types of connections are not possible.
– Connecting with the left channel "–" terminal and the right channel "–" terminal
as well as "+" terminals (Fig. 1).
– Connecting with the left channel "–" terminal and the right channel "–" terminal
inverted (cross connection, Fig. 2).
– Deliberately connecting with the left/right channel "–" terminals and metal part
on the rear panel of this unit, as well as accidentally touching them.
• Do not connect your active subwoofer to the SPEAKERS L/R CH terminal.
Connect it to the PRE OUT jacks.
• Do not connect a component with no volume control, such as a CD player, to the
MAIN IN jacks, as the volume level of the signals input to the MAIN IN jacks is
fixed. If such equipment is connected, a sound may burst, and the unit and/or
speaker may be damaged.
