Hybrid Digital Amplification: NAD has moved away from the old-fashioned power-hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed and produce heat rather than sound. Instead, NAD has developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, this new Hybrid Digital Amplifier design is very linear over a wide bandwidth and provides consistent performance into all speaker loads, providing a dramatic advancement over previous Class AB and Class D amplifier designs.

• Customized Hypex UcD Output Stage: The C 368 BluOS 2i uses a customized version of the proven Hypex UcD output stage operating in a fully balanced bridge configuration. This allows for massive power with nearly un-measurable distortion and noise in the audible range. Every detail of this design has been carefully planned and perfectly executed to deliver every last drop of performance.
• Sophisticated Power Supply: The power supply is capable of 80 watts continuously and over 120 watts instantaneously to allow for short-term musical transients. It can operate with any AC mains voltage from 100 to 240 volts and provides pure DC power to all the various stages of the C 368 BluOS 2i. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.

Full Disclosure Power (FDP): NAD uses Full Disclosure Power (FDP), the most demanding criterion for performance measurement. FDP specifies distortion under the most extreme conditions of low impedance loads and frequency extremes, rather than the simple and easy 1kHz @ 8 ohms test quoted by many of other manufactures. NAD uses this stricter performance criterion because it more closely matches the demands of real music and real loudspeakers. Maintaining specified distortion at 4/8Ω and at 20-20kHz is a much more difficult achievement. The benefit of NAD's Full Disclosure Power is the total elimination of audible distortion at any listening level. This provides pinpoint imaging and realism with music and movies alike.

• Continuous Power:
  • Stereo: 80 watts x 2-channel (@ 20-20kHz, into 4Ω or 8Ω, at 0.03% THD, with both channels driven)
  • Bridged: 300 watts x 1-channel (@ 20-20kHz, into 8Ω, at 0.03% THD)
• IHF Dynamic Power:
  • Stereo: 250W into 2Ω / 200W into 4Ω / 120W into 8Ω
  • Bridged: 560W into 4Ω / 400W into 8Ω

Bridge Mode: The C 368 BluOS 2i amplifier can be configured to be MONO (Bridge Mode), more than doubling its output power. This way, the C 368 BluOS 2i can be used as part of a high power stereo or home-theatre system, by connecting additional power amplifiers.

Binding Post Speaker Outputs: The amplifier features A & B speaker terminals to power two pair of loudspeakers. The speaker terminals consist of eight binding posts that will accept single banana plugs (single only), pin connectors, spade lugs, and bare wire (up to 10AWG). The amplifier supports 4Ω speakers when only one pair is connected, however, when two pair of speakers are connected a minimum impedance of 8Ω is recommended.

Discrete Headphone Amplifier: The NAD C 368 BluOS 2i incorporates a discrete headphone amplifier with low output impedance and very high output voltage capability, enough to drive even high impedance studio monitor headphones. Connecting a set of headphone to unit's front-panel 1/4" jack will mute the speaker outputs. Volume, tone, and balance controls are all operable during headphone listening.

Line Outputs: The C 368 BluOS 2i features a low impedance line-level stereo output that can connect to another other amplifier or powered subwoofer to extend the hybrid digital DAC amplifier's versatility. A 150Hz low-pass filter is activated when configured as a subwoofer out.

Tone Control: The NAD C 368 BluOS 2i hybrid digital DAC amplifier lets you adjust Bass (60Hz) & Treble (20kHz) from -7 to +7dB, as well as Balance between the left & right speakers (L10 to R10).

Filters: Filters provide easy bi-amplification or subwoofer integration by adding the required filters to redirect bass frequencies to the subwoofer. Select High Pass or Full Range. When High Pass is selected, low pass audio signals up to 150 Hz are sent to the C 368 BluOS 2i's subwoofer preout and high pass audio signals are sent to the C 368 BluOS 2i's amplifier section and speaker outputs. Select Full-Range to deliver audio signals with the whole frequency spectrum to the C 368 BluOS 2i's amplifier section and speaker outputs.
