ZA power amplifier is designed for the professional sound reinforcement systems based on the innovative switching mode power supply technology rather than the conventional linear power supply with heavy toroid transformer. It provides the high power output with light weight.

Balanced input: High efficiency electronic balanced circuit is adopted in order to reduce external hum pick up from signal line. Input mode switch: This model is able to distribute the sound signal input to output at 1:10 or 2:5 by mono and stereo selector switch. Level control and peak LED per channel: Capable of adjusting each output volume and in case of excessive input LED lamp warns distortion status. Balanced output and minimize the DC hum: Sound output is possible whether or of the output unit polarity is grounded and the direct current noise is minimized a 15V power source motivates the operation of circuit. Use of emergency battery (SAD-152 ONLY): You can operate this model by using emergency battery for unexpected AC power failure. (Built in DC 24V terminal)
