The QSC RMX2450a is a solid choice for DJs and audio professionals looking for a reliable power amplifier that delivers professional quality performance. With a power output of 800 watts across two channels, it provides strong audio support for various events, making it suitable for both small gigs and larger venues. Its high-current toroidal transformers enhance its performance at lower impedances, specifically 2 ohms, which is a definite plus for those who need extra power without compromising on sound quality. The independent clip limiters help in reducing distortion, ensuring that your sound remains clean even at higher volumes, which is crucial during live performances.
One standout feature is the selectable low-frequency filters at 30 Hz and 50 Hz, which help protect your speakers and improve sound clarity. This functionality is especially valuable for DJs who want to avoid damaging their equipment while still delivering a powerful bass response.
However, this amplifier isn't without its drawbacks. Its size (28 x 6 x 24 inches) can be cumbersome for mobile setups, and it may be less appealing for those with limited space. Additionally, while it includes various inputs like balanced 1/4 inch TRS and XLR, it lacks modern connectivity options like Bluetooth or USB, which could be a downside for some users looking for convenience. In terms of cooling, it’s designed to handle heavy use, but the cooling system specifics aren't detailed. Lastly, while the THD and SNR values are not explicitly stated in the specs, these factors are crucial for sound clarity and performance, and potential buyers may want to look for that information before making a decision. The QSC RMX2450a is a great option for dedicated DJs and audio professionals who prioritize sound quality and performance, but those needing portability or advanced connectivity might want to explore other options.
