Know before you buy
Class G amplification combines the efficiency of Class AB with the high-fidelity performance of Class A. By using the first 20 watts in Class A, the amplifier provides exceptional detail and clarity at lower volumes, while the remaining power reserves kick in for demanding dynamic peaks.
No, the inputs are switchable. You must select either the RCA or the balanced XLR input for each channel depending on your source equipment's output capabilities.
A toroidal transformer is highly efficient and produces less electromagnetic interference than standard transformers. This results in a cleaner power delivery, which helps reduce background noise and distortion for a more precise, stable soundstage.
These ports are designed for system integration and custom installation. They allow you to control and monitor the amplifier remotely through home automation systems or network-based control software.
Yes, with 140 watts per channel across seven channels, the PA720 is designed to handle demanding home theater setups. Its robust build and acoustically damped chassis ensure it maintains control and clarity even during complex, high-volume movie sequences.
Because it is a high-performance amplifier, it will generate heat during operation. It is recommended to place the unit in a well-ventilated area with sufficient clearance on all sides to ensure optimal performance and longevity.
