7.2 Speaker outputs
In stereo mode, the amplifier can operate two speakers or two speaker groups.
For connecting speakers, Speaker jacks are provided. When using the Speaker jacks, turn each plug to
the right until it locks into place. For unlocking, pull the unlock button and turn the plug to the left.
• Occupation Speaker socket:
The Speakers Impedance must be greater than 4 ohms / channel at all times in stereo mode !
Information on choosing appropriate connection cables
• Speaker systems must only be connected via sufficiently dimensioned cables. Too thin cables lead to
cable heat up or enormous power loss and loss in sound quality.
• For all speaker systems up to 400 Watts, we recommend a cable diameter of .5 mm, for all other
speaker cables 4 mm.
• A high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and
thin cables will influence the damping factor and thus the low frequencies in a negative way. In order to
safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be,
the thicker it should be. In this respect, a damping factor of 00 will be reduced to 47 (8 ohms) when
using a 10 m long, .5 mm speaker cable. The power loss at 8 ohms is 1.63 %, at 4 ohms 3.5 % and
at ohms even 6.5 %.
• The maximum cable length is 30 meters!
