Description
AudioControl Avalon G4 4-Channel Class H Power Amplifier
Exceptional Detail and Clarity from an Innovative Class H Design
The AudioControl Avalon G4 is a four-channel Class H power amplifier that builds on the award-winning Savoy G3 amplifier platform to deliver exceptional detail and clarity with an innovative and highly efficient amplifier topology that effortlessly achieves 230 watts per channel with all channels driven. The Class H design provides superb audio quality and bullet-proof reliability while reducing heat dissipation from a compact form factor, making the Avalon G4 an ideal solution for home theatre processors and immersive surround formats or as a premium standalone power amplifier for virtually any home audio system. Made in the USA and designed as a perfect match for AudioControl’s home theatre preamplifiers, the Avalon G4 combines the versatility of multiple configuration options with the sonic refinement and engineering integrity that AudioControl’s professional heritage demands.
Class H Amplification with High Definition BiMOS Outputs
AudioControl’s Class H amplifier topology achieves exceptional efficiency and cool running operation by dynamically adjusting the power supply rail voltage to track the audio signal, reducing heat dissipation and power consumption at typical listening levels without any compromise to the amplifier’s dynamic capability during peak demand. High Definition BiMOS output devices deliver the combination of bipolar transistor current handling and MOSFET smoothness that defines the Avalon G4’s sonic character, with a damping factor greater than 450, total harmonic distortion of just 0.04% at full output across the full 20Hz to 20kHz audio band, and a signal-to-noise ratio greater than 102dB (A-weighted, referenced to full output). The Avalon G4 can be bridged to 600 watts mono into 8 ohms on any channel pair for applications requiring greater power, and remains stable into a minimum speaker load of 4 ohms throughout.
Versatile Multi-Mode Configuration
The Avalon G4 supports multiple operating modes including four-channel, 2.1-channel, and high-power two-channel configurations, all without the need for external DSP management. Each pair of channels features hi, lo, and bypass crossover controls, allowing the Avalon G4 to be configured as a 2.1 solution with an integrated crossover point for a subwoofer without requiring a separate processor or active crossover. Independent channel level controls, four RCA unbalanced and four XLR balanced inputs per channel pair, and RCA throughput outputs provide the flexibility to achieve a wide range of system configurations and integration scenarios. AudioControl’s LightDrive anti-clipping protection circuit safely eliminates any possibility of speaker-damaging clipping and distortion even under the most extreme dynamic conditions, such as a highly dynamic action film soundtrack, while comprehensive protection against short circuit, thermal overload, and DC offset ensures long-term loudspeaker safety.
Made in the USA, Built for a Lifetime
The Avalon G4’s audiophile-grade 5-way binding posts accommodate the full range of loudspeaker cable terminations, and a 12V remote power trigger is provided for automated system switching compatible with both contact closure and external 12V sources. The Avalon G4 is perfectly paired with AudioControl’s Maestro M9 or M5 preamplifiers for a complete and cohesively engineered system solution, and its compact form factor and cool-running Class H operation make it well suited to any installation environment where heat management and space efficiency are considerations.
