Reviews QSC PLX 2502

Nicolas358, 23.05.2011
First, it is an amp with switching power supply.
It implies that it is well on light but also that it can have questionable acoustic behavior.

Good news, the sound goes very well. The basses are nervous and the amp does not seem to want to heat excessively. The medium is clean but it is for the treble or I find a sound a bit retained as if it did not rise as high as the type of amplification I used before migrating to QSC. Nothing very serious either, but I still felt this difference.

Very good news, the range PLX ending in 02 in its reference announces being able to work at full speed without forcing up to 2 ohm. Congratulations, I confirm that there is no problem of heating or other quirk of clip lighting up for various reasons. This amp is perfectly healthy.

The negatives that I remember:
- Complicated troubleshooting see costly as is the case with most amps with switching power supply.
- small weakness to my taste in acute (but it is quite personal and subjective).

The PLX range is well thought out. I have built racks based on a PLX 2502 for heads, a PLX 3602 for subs and 1 dbx drpa for filtering.
It is a range that is not fragile and deserves its renown in the professional world.

A very good final stage of the upper middle class! Reliable in operation, stable both with regard to the controlled fan as well as to the idle operation and very load-bearing.

With only 9.5 kg, the QSC PLX 2502 is a real lightweight. With regard to the equipment (connections, protective circuits, etc.) everything is available, what you need. Even a switchable crossover with a fixed frequency at 100 Hz is on board. Only the removable power cable is really worth the upgrade, a Powercon connection would be much better.

Unusual, but with QSC tradition, ventilation is from the rear to the front. It is therefore not recommended to use a combination of power amplifiers from other manufacturers in the rack. On the other hand, it is possible to install it together with other 19 "equipment, as the rear rack area is kept cool.

Conclusion: If you have a reliable, long - lasting amplifier in the power range of approx. 2 x 500 to 800 Watt @ 4
