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 388 BluOS 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 C 388 BluOS's power supply is capable of 200 watts continuously and over 600 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 388 BluOS. 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 mosat 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: 150 watts x 2-channel (@ 20-20kHz, into 4Ω or 8Ω, at 0.009% THD, with both channels driven)
- IHF Dynamic Power: 400W into 2Ω / 350W into 4Ω / 250W into 8Ω
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 388 BluOS 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 388 BluOS 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.
Tone Control: The NAD C 388 BluOS 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 within the 40Hz to 200Hz are sent to the C 388 BluOS's subwoofer preout and high pass audio signals are sent to the C 388 BluOS's amplifier section and speaker outputs. Select Full-Range to deliver audio signals with the whole frequency spectrum to the C 388 BluOS's amplifier section and speaker outputs.
Bluetooth Music Streaming: You can wirelessly pair and connect instantly to the C 388 BluOS with Bluetooth (4.0), allowing you to stream stored music and music apps wirelessly from your Bluetooth-enabled source device; like your smartphone, tablet, laptop or desktop computer. The high performance Bluetooth aptX codec is fully supported for true CD-quality sound from aptX-compatible Bluetooth devices (like Android OS 4.0+ smartphones & tablets). There is no control or song/artist info display from the C 388 BluOS.
Note: Make sure to plug in both antennas to the "BT Antenna" ports on the rear-panel.
Dual USBA Ports: The MDC DD BluOS module features two USB (type-A) ports to directly connect your USB mass storage class (MSC) device; such as a thumbdrive or external hard-drive. The unit's USB ports support music playback from these compatible USB devices formatted in FAT 32. Not only can USB audio be played back on your compatible NAD digital integrated amplifier or digital pramplifier, but can also be wirelessly distributed to the rest of your Bluesound components throughout your home for multiroom playback. The USB port is not compatible with the direct connection of an Apple iPod/iPhone/iPad or Android devices.
Note: There is also a mini-USB (type-B) port and a third USB (type-A) port that are used for service purposes only (not for consumer use). Only authorized service personnel can access this USB port.
Digital Inputs: The NAD C 388 BluOS is equipped with two optical (toslink) digital inputs and two coaxial (RCA) digital inputs. These digital inputs will support 2ch PCM audio up to 24-bit/192kHz (not compatible with Dolby Digital/DTS).
Analog Inputs: The NAD C 388 BluOS's stereo RCA inputs (2 Line/1 Phono) can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device.
MM Phono Stage w/ RIAA Equalization: The NAD C 388 BluOS hybrid digital DAC amplifier includes an MM Phono stage with precisely accurate RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs - all without affecting bass response.
