THE CREST AUDIO 7301 IS A TWO RACK SPACE, COMPACT POWER AMPLIFIER SPECIFICALLY DESIGNED FOR USE IN BI-AMPLIFIED SYSTEMS, INCLUDING STAGE MONITOR, STUDIO MONITOR AND FRONT-OF-HOUSE APPLICATIONS. THE LOW FREQUENCY CHANNEL (CH. A) UTILIZES CLASS H OPERATION, WHICH INCREASES EFFICIENCY AND YIELDS HIGHER OUTPUT POWER ON THE LOW END. THE HIGH FREQUENCY CHANNEL (CH. B) UTILIZES CLASS AB OPERATION WHICH IS OPTIMIZED FOR PRECISE REPRODUCTION OF MID AND HIGH-FREQUENCY SIGNALS.
