The GL Series of professional Power amplifiers form VAL Audio represents a new dimension in high quality amplification with unmatched reliability, performance and affordability.

This conventionally designed series of professional power amplifiers features 3 models GL1200, GL2000 and GL2800, offering unmatched quality at a very affordable price. Designed ground up for Live as well as install segments these power packed amplifiers feature robust toroidal power supplies and deliver pure clean sound across the frequency band. The GL series is an installers delight as it features an inbuilt Xover, thus adding the flexibility of running smaller systems without the need for outboard processing and DSP. The inbuilt Xover can be used in bypass, High pass or low pass modes. It features a variable frequency range from 30Hz to 180Hz. The GL1200 is a traditional class AB design and GL2000 & GL2800 feature efficient class H design. Each of the amplifiers have a user selectable input sensitivity of 0.77V / 1.0V / 1.4V.

Affordability is a key concern but not at the cost of our high quality standards and most importantly our signature HIFI sound quality. Even the entry level GL1200 is capable of driving a fullrange speaker without running out of breath. Welcome to the world of maximum performance, reliability & portability at a limited budget.
