Table 4.1: Pin assignment

4.1 Subwoofer (PASSIVE)

sFeed the full-range signal to the input PINS 1-/1+. The high-
pass signal can be tapped into at the output PINS 1-/1+.
PINS 2-/2+ serve as a signal loop through.

4.2 Subwoofer (BI-AMPING)

sConnect the subwoofer signal to PINS 2-/2+.
sPINS 1-/1+ of the input are connected to PINS 1-/1+ of the
output, and can be used to loop the signal through.
sIn general, when in BI-AMPING mode, PINS 1-/1+ and PINS
2-/2+ are looped through.
5. ADDITIONAL CONSIDERATIONS

5.1 Length and diameter of loudspeaker cables

Loudspeaker cables whose diameter is too small can
considerably limit the power amp performance. The longer the
cable, the more pronounced the problem. As a result, musicians
often simply turn up the amp, which can lead to loudspeaker
damage. Therefore, dont use cables longer than 15 m (45 ft.).
For most applications, this will not be necessary. Cable diameter
should be at least 2.5 - 4.0 mm2.

5.2 Power amp rating

Selecting the right amp can turn out to be rather difficult.
Therefore, stick to the following rule of thumb: the power rating
