Know before you buy
Class G amplification allows the amplifier to run in pure Class A mode for the first 50 watts, providing exceptional detail and clarity at lower volumes. As power demands increase, it seamlessly switches to a more efficient Class AB design to handle dynamic peaks without distortion.
Yes, the PA240 supports bridged mode, which combines the two channels into a single, high-power output of 790W into 8 ohms. This is an excellent option if you are driving demanding speakers that require significant headroom.
Yes, the PA240 features switchable inputs, allowing you to connect your pre-amplifier or source via either RCA (unbalanced) or XLR (balanced) cables. Balanced XLR connections are recommended if you are running longer cable lengths to minimize potential interference.
In Dual Mono mode, the amplifier treats the left and right channels as completely independent units. This configuration helps reduce crosstalk and improves channel separation, resulting in a more precise and expansive soundstage.
Yes, the amplifier includes Ethernet and RS232 control ports. These allow for seamless integration into custom home automation systems, enabling remote power control and status monitoring.
The PA240 is built with an acoustically damped chassis to minimize internal vibrations and interference. It also utilizes a high-quality toroidal transformer, which is essential for maintaining stable power delivery and long-term reliability.
