4.1 Subwoofer (PASSIVE)

s

Feed the full-range signal to the input PINS 1-/1+. The high-

s

PINS 1-/1+ of the input are connected to PINS 1-/1+ of the

output, and can be used to loop the signal through.

In 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 mm

Therefore, stick to the following rule of thumb: the power rating
