The NAD CI 980 is an 8-channel amplifier for professional installations. Output power is 8 x 50 W, at 8 ohms / 2 x 120 W, at 8 ohms (bridge connection). The ability to work in 4 zones. Individual level adjustment for each zone. Removable Phoenix-type acoustic terminals. Brackets for mounting in a rack rack.
The seven-channel Masters M28 power amplifier embodies everything that is possible with modern amplification technology. It is one of the first amplifiers to use Purifi Eigentakt amplifier technology.
With balanced inputs, the C 268 is a natural choice for high-performance preamps and processors. These inputs have a trim control function, for matching with other components, or for two-amp connection to speakers. The through-line output allows you to add another power amplifier to the same channel for additional speakers or subwoofers. In addition, there is a bridge switch that turns the C 268 into a surprisingly powerful monoblock amplifier.
Hypex UcD amplification modules are installed inside the thin case, delivering up to 120 Watts per channel in class D, while in bridge mode their power increases to 200 watts. However, at the same time, the number of channels is reduced by half. On the front panel there are LED indicators showing the number of active modules, as well as ventilation grilles that ensure heat dissipation from the output stages.
The power is 150 watts for each of the eight channels, and in bridge mode, the device can output up to 365 watts for four channels. In addition to the analog and network inputs, the amplifier has optical and coaxial digital inputs. The device is built on Hyperx amplifier modules, network control and equalizer settings via a network interface are also provided.
