Product Description
The QSC PT-225004-00 is a genuine QSC replacement gain potentiometer designed for use in compatible QSC RMXa and RMX DTV series power amplifiers. This specialized replacement control is used for the amplifier's front-panel gain adjustment and is ideal for repairing a damaged, worn, or malfunctioning gain control.
QSC identifies PT-225004-00 as a 2.5 kΩ gain potentiometer with a 20% tolerance, 0.05 W rating, 0.75-turn rotation, and 21 detents. The component features a right-angle mounting configuration and D-shaped shaft, making it suitable for the original amplifier control layout.
The QSC spare-parts database specifically states that this potentiometer works on RMXa and RMX DTV models. Compatible RMXa amplifiers include the RMX 850A, RMX 1450A, and RMX 2450A, making this a useful service part for maintaining these professional 2-channel QSC amplifiers.
The RMXa series uses independent front-panel gain controls for Channels 1 and 2, making the gain potentiometer an important component of the amplifier's user interface.
