CHANGING THE STEREO/QUAD (4-CH) SWITCH
The receiver operates 22W x 4-CH when the switch is set QUAD (4-CH) side and 44W x 2-CH when the switch is set
STEREO side at rated power.
The switch is set at QUAD (4-CH) side. If you want more output with stereo signal, please change the switch setting
from QUAD (4-CH) side to STEREO side. To change the switch setting, remove the black screw at left side of the switch
and remove a black plate for fitting the switch knob.
When the unit operates in STEREO mode, signal output comes only to LEFT FRONT and RIGHT FRONT speaker
terminals (No signal at LEFT BACK and RIGHT BACK terminals).
