Combining the proven features of the best-selling GL3300 and the latest features of the GL2800, the Allen & Heath GL3800 is destined to become a leading 8-bus console for live or recording work. The GL3800 is available in frame sizes up to 48 channels, with the choice of all mono, 4 or 8 stereo channels housed in a stylish chassis, including a meterpod with illuminated VUs, and front and rear indent strips.
The GL3800 has been updated with more facilities for modern day mixing—it’s truly dual-function with all 10 auxes configurable to fader control with insert point and XLR drive. The GL3800 has internal circuitry to autoswitch a second PSU where a fail-safe operation is desirable, and now with ultra-smooth dual rail K faders, this console will be a favorite of the connoisseur operator. The GL3800 is the latest edition of the highly-successful GL3000 family, which has proved to be the ultimate mixer package for fixed installations over the last 10 years. It has all the professional features required for day-in, day-out use in theatres, houses of worship and concert halls: high specification, high quality feel and exceptional sound performance, while its rugged construction and individual circuit board design ensure that the GL3800 is built to last a very long time.
