NAD C 298 Amplifier: Class D, Switching Power Supply, Auto Input Trim, and Purifi Eigentakt Technology
NAD Electronics presented the NAD C 298 power amplifier. The novelty is made in class D. On the manufacturer’s website, as an option, a combination of the novelty with the NAD C 658 DAC-preamplifier-streamer, which we have already talked about, is proposed. The C 298 is powered by efficient switching power supply circuits. The circuit contains modules Eigentakt, which are manufactured by NAD under license from the Danish company Purifi. Purifi Eigentakt technology provided 185 watts per channel with an 8 ohm impedance of 298 speakers connected to the C (the amplifier outputs 340 watts to 4 ohms speakers, and more than 570 watts at the peak).
There is a slide switch on the back of the amplifier that puts the C 298 into bridged mode. In this case, with an 8-ohm speaker, the power of the resulting monoblock can reach 620W. The C 298 provides switching between balanced XLR or unbalanced RCA inputs, equipped with an auto-sensing input signal with a selectable threshold. In addition, there is also a line-out (RCA only) – you can connect additional amplifiers or an active subwoofer. For multi-component setups, the C 298’s ground terminal is useful.
The NAD C 298 amplifier will be on sale in October. Its suggested retail price for the US market was $2,000.
