Lab.Gruppen 20:8X 2,000 Watt 8-Channel Amplifier w/ NomadLink Network Monitoring and Dedicated Control forInstall Applications

$0.00

The C 20:8X is the most powerful eight-channel amplifier in the C Series family, delivering an impressive 8x 250 W at 4 ohms, 8 ohms, 16 ohms or 70 Vrms; 500 W at 100 Vrms is available in bridge mode.

The C 20:8X is one of four C 20:8X models in the C Series, each uniquely suited for a range of installed applications with relatively lower power output requirements. C 20:8X models share most features of the original (higher power) C Series models, and they share the same compact, lightweight 2U chassis. However, the C 20:8X models are offered in both four- and eight-channel versions, offering even greater channel density and installation flexibility. Also, because the unique benefits of Class TD are more applicable at higher power levels, the C 20:8X models employ a cost-efficient proprietary Class D output design. Other features unique to C 20:8X models include a universal power supply, selectable 35 Hz high-pass filter, and built-in GPIO control facilities.

C 20:8X 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 a single large subwoofer or a series of small 70 V loudspeakers (100 V in bridge mode). VPL works in combination with adjustable input gain (adjustable in 4-channel blocks) to achieve maximum headroom regardless of input levels or output impedances. Additionally a 35 Hz high pass filter may be inserted in each 4-channel section.

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.

GPIO facilities - provided exclusively on C 20:8X models - allow access to key amplifier functions such as power on/off and fault reporting.

Maximum continuous output power, all 8 channels driven, VPL set at 100 V and Gain set at 32 dB.

About the Lab.Gruppen 20:8X 2,000 Watt 8-Channel Amplifier w/ NomadLink Network Monitoring and Dedicated Control forInstall Applications

The Lab.Gruppen 20:8X is an advanced eight-channel network amplifier engineered to provide high-density power distribution and intelligent system management for sophisticated multi-zone installation environments. Delivering a substantial 2,000 watts of total power across its eight independently addressable channels, this unit offers exceptional granularity for complex audio architectures found in corporate campuses, large houses of worship, transportation hubs, and hospitality complexes. By incorporating efficient Class D technology within a space-saving 1U rack chassis, it achieves an outstanding balance of power, channel count, and energy efficiency, making it an ideal solution for systems requiring numerous discrete zones of control while minimizing rack space, cooling demands, and operational power consumption.

The amplifier's core intelligence is delivered through its integrated NomadLink network monitoring and dedicated control system. This feature transforms the unit from a passive power source into a smart, communicative network asset. Via a standard Ethernet connection, system administrators gain comprehensive remote oversight, including real-time monitoring of each channel's operational status—such as output power, thermal conditions, and load impedance. The platform allows for remote configuration of critical parameters like input gain, channel muting, and preset selection, and can deliver instant alerts in the event of any fault. This level of centralized, proactive management is invaluable for installations where amplifiers are located in secure or hard-to-access technical rooms, enabling rapid diagnostics, preventative maintenance, and maximizing system uptime.

Built for the reliability demands of 24/7 operation, the 20:8X incorporates robust protection against short circuits, overloads, DC offset, and thermal stress. Its connectivity is streamlined for professional installation, utilizing terminal block connections for both inputs and outputs to ensure clean, secure wiring. The combination of high channel density, reliable power delivery, and advanced network-based management makes the Lab.Gruppen 20:8X a powerful, intelligent, and future-proof amplification solution. It is expertly suited for environments where operational reliability, detailed zonal control, and the ability to remotely manage and monitor the entire audio system from a central location are indispensable requirements.
