LF- connection cords
Choosing high-quality balanced cables( two conductors for the audio signal plus sepearate shielding
mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting
unbalanced cables to the power amplifier inputs is possible as well, using balanced cables is always
preferable. A great number of today s audio appliances employ balanced outputs. Wi th balanced cabling,
the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction of
external interference-mostly noise and hum.

Selecting Stereo / Parallel / Bridge Mode
Stereo Mode
Each channel within the pair remains independent, and each may be used for a different
signal.
Parallel Mode
This setting connects both inputs of a pair together. One signal feeds both channels. Do
not connect different sources to each input. Each channel s gain control and speaker
connection remain independent.
Bridge Mode
This setting combines both channels of a pair into a single channel with twice the output
voltage. Use only the first channel s input and gain control. Set the second channel s gain
control at minimum.
