Lab.Gruppen C 68:4 Overview
System installers in search of a powerful and flexible amplifier with Hi-Z and Lo-Z capabilities should check out the Lab.Gruppen C 68:4, a 2 RU, four-channel 6800W amplifier that's designed to power anything from one massive subwoofer to a series of small 100V loudspeakers. The amplifier is well suited for retail, hospitality, night clubs, bars, performing arts centers, convention centers, hotels, theme parks, houses of worship, and more. The C 68:4 utilizes Class-TD technology, which delivers the exceptional efficiency of Class-D while retaining the superior sonic quality of the best Class-AB output stage.
The C 68:4 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 and Network Controller.) The rear panel features four 3-pin Phoenix connector inputs and four 2-pin barrier strip outputs. A power cord is included.
- 6800W, 4-channel amplifier with up to 1700W output per channel and NomadLink network for monitoring and control
- Selectable gain plus scalable voltage-peak limiter (VPL) and bridge-mode operation allow custom configuration for any application
- 4 x 1200W into 2 ohms; 4 x 1700W into 4 ohms; 4 x 1200W into 8 ohms; 4 x 650W into 16 ohms; 4 x 1600W into Hi-Z 70Vrms; and 4 x 1200W into Hi-Z 100Vrms
- Proven and reliable Class-TD output stage delivers Class-AB audio quality with Class-D efficiency
- Regulated Switch Mode Power Supply (R.SMPS) ensures constant power output at all times
- Intuitive DeviceControl software monitors and controls key functions via the NomadLink network
- Comprehensive protection scheme including current, voltage, DC, temperature, short-circuit, and open-load warnings
- Efficient Intercooler copper cooling system dissipates more heat for extended peak output
- 4 balanced analog audio inputs on 3-pin Phoenix connectors
- 4 barrier strip 2-pole screw terminal output connectors
- Removable dust filter grille for increased air circulation
- Compact and durable 2 RU rackmount chassis saves space in install applications
