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 inperformance when the distance between amplifier and speaker systems exceeds 50 m. This method alsooffers an easy way of output power distribution. The total po...
