Hardware for GXR-D15A
Enclousure-v12
Enclosure

The GXR-D15A cabinet is constructed from 13-ply premium birch plywood (18mm thickness) and finished with polyurea coating.

Internal design

The internal structure of the cabinet is heavily braced for greater longevity and all parts are assembled on metal inserts with metric screws. The amplification modules & DSP are housed in a separate chamber to the drivers avoiding excessive heat & vibration, thus delivering greater efficiency and reliability.

Rear panel

The powder coated steel rear panel contains all connections and houses the GXR-D15A amplification modules and DSP, is easily accessible and housed separately from the drivers for increased reliability and efficiency.

Grill

The cabinet has a heavy duty, powder coated front grille with a special acoustic rear fabric to protect the transducers against dust and dirt.

Handles

Four handles are located on each side of the enclosure to facilitate transport, positioning and loading of the cabinets.

Rigging

Built-in flying points are located on each side of the enclosure to link the cabinets together or fix it to the flying frame.

Transport

The cabinet is easy to transport thanks to its dedicated dolly and a protective nylon cover is also available to protect the enclosure and keep it clean on tour.

Amplification & DSP
Bi-amplified Class D with switching power supply and PFC (Power Factor Correction). With PFC the power supply regulates itself when AC mains change, so the amp power output will not change with mains swinging. The amplification far exceeds the transducers needs thus resulting in high output, high damping factor and extremely low levels of distortion.
 
This system is also very environmentally friendly with a reduction of approximately 40% of current draw.
