완벽한 인스톨레이션 앰프

Installed or on tour, uncompromising quality begins with superior sound. Over the past decade, the sound of Lab.gruppen ampli-▸ fiers 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 Supply™ (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 massive subwoofer or a series of small 100 V loudspeakers. VPL
works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.
To assure reliability, and minimize service interruptions, C Series amplifiers offer comprehensive warning and protection features. Whenever faulty wiring, improper use, or extreme ambient temperatures threaten trouble, a C Series amplifier gives clear and accurate warning indications. Protection measures are inserted only when dangerous thresholds are passed. Conditions are re-checked at six-second intervals, and normal operation resumes when measurements return to nominal.
Every C Series amplifier is ready for the NomadLink network right out of the box. With NomadLink, key amplifier parameters are displayed via DeviceControl software, and remote control of channel mutes and power on/off is under network control. (NomadLink requires the separate NLB 60E NomadLink Bridge & Network Controller.)
