    5.2 POWER OUTPUT with 100 V speaker systems The use of speaker systems with a 100 V matching transformer is recommended to reduce the lack in performance when the distance between amplifier and speaker systems exceeds 50 m. This m ethod also offers an easy way of output power distribution. The total power consumption of the max imum amount of the c ...
