DISC Lab Gruppen D120:4TA Amplifier

Full Description

Lab Gruppen D Series

The Lab Gruppen D series offers total integration of the widest range of digital audio and control protocols, offering powerful and unique benefits and capabilities. The D 120:4TA is an advanced install-dedicated amplifier, part of the Lab Gruppen D Series. Available in two variants, each with three different power models to suit any specific application. The first variation delivers the proven quality of Lake Processing combined with Dante, while the second features the ground breaking collaboration with Biamp Systems for complete integration with their Tesira DSP platform.

The D series is available in 3 different power configurations of 8000 W, 12000 W and 20000 W and also boasts the introduction of Rational Power Management (RPM). This allows for true flexibility of power allocation without any loss of channel count. It is the most efficient use of the amplifiers inventory.
