Amplifier Overview
9
• A 3-channel amplifier: This amplifier is incorporated into the Allegro MX-1’s internal sound
system, providing sound for audio zone 1. The 3-channel amplifier supports daisy-chaining of
audio components.
• A 4-channel, 2-zone amplifier: This amplifier provides sound for audio zones 2 and 3, and does
not support daisy-chaining of equipment.
The 3 and 4-channel amplifiers incorporate the following features:
Benefits of these amplifiers include:
• Requirement of only N-Channel MOSFET output transistors.
• Dramatic improvement in efficiency versus Class AB amplifiers.
• Signal fidelity equal to high-quality linear amplifiers.
• High dynamic range compatible with digital media.
