An Installation Amplifier without Compromise

Installed or on tour, uncompromising quality begins with superior sound. Over the past decade,the sound of Lab gruppen amplifiers has earned praise from renowned FOH engineers and owners of the world’s premier sound rental companies. At the core of the C Series high-power* model’s tight and transparent sound is patented Class TD technology. As a proprietary implementation of tracking Class▸D,Class TD approaches the exceptional efficiency of  Class D while retaining the superior sonic quality of the best Class B output stages.

A Regulated Switch Mode Power SupplyTM (R.SMPS) contributes to the remarkable efficiency of the C Series high-power models, while at the same time providing stable operation even with wide fluctuations  in mains voltage. R.SMPS also works in conjunction with Class TD to give extraordinary power density. More channels with more power are condensed into a smaller package, allowing C Series amplifiers to  minimize rack space requirements and reduce installation costs.

Extreme power density demands efficient cooling, and here Lab gruppen’s Intercooler proves remarkably effective. Thousands of small copper cooling fins dissipate heat, and all output devices are mounted on one row perpendicular to airflow for uniform cooling.

C Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL), which allows the output to be optimized for any loudspeaker load whether one
