Lab.gruppen C 68:4
The C 68:4 delivers 4 x 1,700 W into 4 ohms, which covers the majority of demanding installed sound systems without moving up to the C 88:4. Four channels in one frame keeps the rack short.\n\nSelectable gain plus a scalable Voltage Peak Limiter and bridge mode operation let you tune the amplifier to the cabinet rather than the other way round. The Class-TD output stage gives Class A/B audio quality at Class D efficiency, and NomadLink reports status over the network.
