System installers in search of a powerful, flexible amplifier with Hi-Z and Lo-Z capabilities should check out the Lab.Gruppen C 28:4, a 2 RU, four-channel 2800W amplifier that's designed to power anything from one massive subwoofer or 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 28:4 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 28:4 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.
