Removal of the midrange drive unit

user manual

QLight series

If the midrange drive unit requires maintenance, it will first be necessary to remove the amplifier module. The midrange driver is held in place by a M10 x 25mm bolt through the rear of the cabinet into the back plate of the drive unit underneath the amplifier module. Once this is released the midrange horn and drive unit assembly can be removed.

1.Remove the amplifier module as described above and set it aside.

2.The M10 bolt securing the midrange driver will now be accessible in a recess in the enclosure rear panel. Using a 17mm socket, unscrew the bolt and set aside for later re-assembly.

3.Unscrew the eight countersunk screws from the two vertical battens which hold the protective grille in place. Be careful when removing the grille as it is under tension and may spring outwards when released. Set the battens, grille and fixing screws aside for later re-assembly.

4.The midrange horn is secured through the mounting flange with four # 10 x 1/12” pan head wood screws. Unscrew these and lift out the horn and driver assembly.

5.Disconnect the cables, making a note of the polarity, and carefully lift the driver clear.
