Wired connections

Want to improve your TV sound? Run an HDMI or optical digital audio cable to the back of the D 3045. There's a coaxial input for digital music, and a stereo RCA input for analog. If you have a turntable, there's a separate phono input for 'tables with moving magnet cartridges. High-res digital files stored on your computer get the red-carpet treatment when you connect to the Type-B USB port, which can handle files up to 24-bit/384kHz. 

Two-way Bluetooth

Wireless streaming is convenient and ubiquitous, but that doesn't mean it can't sound good. The D 3045 uses Bluetooth with aptX® encoding that provides clear, detailed audio quality. And the wireless fun goes both ways — the amp streams music to Bluetooth-enabled speakers and wireless headphones, too.

Product Research


Hybrid Digital Amplifier: The NAD D 3045 is a hybrid digital amplifier which incorporates NAD's PowerDrive and Soft Clipping technology for dynamic power, low distortion and noise, and minimal power consumption. Even at 60 watts x 2 channel, the D 3045 has the ability to drive "power hungry" and low-impedance loudspeakers to satisfying levels without adding noise or distortion.

  • NAD PowerDrive Circuit: The D 3045 use NAD's proprietary PowerDrive amplifier technology that provides high dynamic power and low impedance drive capability. This uniquely efficient power supply topology provides the real world benefits of high dynamic power that remains uncompromised by low impedance speakers.
  • NAD's Full Disclosure Power Ratings: 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 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 ohms and at 20Hz to 20kHz is a much more difficult achievement. The NAD D 3045 is rated at 60 watts x 2 channel (@ 20-20kHz, in 8, with 0.03% THD).
Note: The D 3045's highly efficient design wastes less energy resulting in cooler running and longer life; standby power consumption is <0.5W.

Bass EQ & High-Pass: An innovative Bass EQ circuit helps small speakers sound bigger without overdriving or damaging drivers. It boosts the overall bass response by at least 6dB. The High-Pass feature attenuates really low frequency signals below the indicated cutoff frequency (40, 50, or 120Hz) to allow high frequencies to pass through cleanly.

24-Bit/192kHz DAC: The NAD D3045 digital hybrid amplifier utilizes a 24-bit/192kHz DAC (digital-to-analog) converter for playback of high resolution music files - including PCM, DSD, & MQA.

Asynchronous USB Input: The NAD D 3045 hybrid digital amplifier is equipped with an Asynchronous USB-B input for attaching a computer which allows High Res streaming using one of the several High Res programs like Roon, JRiver, and Amarra. Asynchronous operation uses the D 3045's precision clock (instead of the computers clock) to reduce jitter to a minimum and make the USB format work ideally for audio. The Asynchronous USB-B input supports PCM, DSD & MQA audio files (up to 24-bit/192kHz) only.

  • Compatible with Microsoft Windows 7 or higher.
  • Compatible with Mac OS Snow Leopard (version 10.6) or later versions.
Note: Visit NAD's website to download the NAD USB audio driver.

Optical & Coaxial Digital Inputs: The NAD D3045 is outfitted with one digital coaxial (RCA) input and two optical (toslink) digital inputs for connection of your digital audio sources like CD and DVD players, satellite/cable boxes, or Apple TV. The unit will accept 2-channel PCM & MQA audio signals (up to 24-bit/192kHz) from the Optical or Coaxial inputs (not compatible with Dolby Digital or DTS).

Note: There is an Auto Sense feature that enables the D 3045 to wake up from standby mode and start operation by selecting Optical 1, Optical 2, or the last digital source before going to standby mode.

MQA (Master Quality Authenticated): Master Quality Authenticated (MQA) is a revolutionary end-to-end technology built into the D 3045 that captures and delivers master quality audio. The NAD D 3045 include a powerful decoder and audio renderer for the MQA system. This ensures that MQA-encoded audio files sound exactly like the source. The D 3045 supports and plays back MQA content from a USB-B, Optical, or Coaxial digital audio source.

Note: foobar2000 is a free advanced audio player for Windows PC & Mac computers that is required for playback of MQA audio files through the NAD D 3045's USB-B input.

HDMI ARC (Audio Return Channel): The NAD D3045's HDMI ARC jack supports connection to an HDMI ARC input jack on your TV. With an HDMI ARC connection established, the D 3045 will output audio signal from your TV. The unit's HDMI ARC jack only supports 2ch PCM (not compatible with Dolby Digital or DTS).

Line-Level and MM Phono Inputs: The D3045 offers a stereo minijack (3.5mm) input, a stereo RCA input, and a Phono (MM) input. The stereo minijack (3.5mm) input can be used to connect an external portable audio device, like a MP3 player. The stereo RCA line-level input can be used to connect a CD player or AM/FM tuner. The Phono (MM) input is used to connect a turntable with a moving magnet cartridge and includes a highly accurate RIAA EQ. These analog input jacks are all gold-plated for excellent signal transfer.

Built-in Bluetooth: The NAD D 3045 hybrid digital amplifier offers built-in Bluetooth and can act as wireless audio receiver to receive audio from a Bluetooth source device or as a wireless audio transmitter to transmit audio to a set of Bluetooth headphones.

  • Wireless Audio Receiver w/ aptX HD: The NAD D 3045 supports Bluetooth wireless audio streaming featuring Qualcomm aptX HD, the latest 24-bit High Res version of Bluetooth that is being supported by newer smartphones, tablets, and laptops. Qualcomm aptX HD audio ensures that D 3045 can deliver High Definition (HD) audio. It preserves sound data through the audio transmission, resulting in a "better-than-CD" listening experience. With aptX HD, listening to music at the highest audible quality is possible with the D 3045.
  • Wireless Audio Transmitter: The NAD D 3045 can also be used as a Bluetooth transmitter to wirelessly stream your non-Bluetooth analog & digital audio sources to a set of Bluetooth enabled headphones.

Low-Impedance, High-Current Headphone Amp: The NAD D 3045's front-panel 1/8" (3.5mm) headphone jack lets you plug in your wired headphones to enjoy the exceptional performance of the unit's built-in low impedance, high current headphone amplifier. This high current, low impedance headphone amplifier will drive even the most power hungry headphones, including planar magnetic designs. Once headphones are connected to the D 3045, your connected speakers will be turned off.

Binding Post Speaker Terminals: The NAD D 3045 hybrid digital amplifier is equipped with four gold-plated binding post terminals to connect a pair of loudspeakers (4 or 8). The binding post speaker terminals will accept bare wire (up to 10AWG), banana plugs (single only), pin-connectors, and spade-connectors. Plastic caps inside the binding posts must be removed to use banana plugs.

Pre/Sub Outputs: The NAD D 3045 is equipped with a set of gold-plated stereo preouts that can be used to connect an more power amplifier or a powered subwoofer. The Pre/Sub output is full-range and non-filtered.

Remote Control w/ TV Connect: The NAD D 3045 comes with an IR remote for wireless operation of the hybrid digital amplifier. You can turn the amplifier on/off, raise/lower volume, and switch sources from the remote. The playback controls (including Play/Pause & Previous/Next Track) on the remote are for Bluetooth audio streaming only. The TV Connect features enables the D 3045 to learn the mute and volume control commands from practically any TV remote control. Additionally, the hybrid digital amp will automatically power up to the Optical 1 or 2 input source upon detection of a digital TV output signal.

+12V Trigger Input: The +12V trigger input (3.5mm) lets you turn on/off the D 3045 from another device with a +12V trigger output.

Auto Standby: The D 3045 can be setup to automatically go into standby mode if there is no user operation and no audio source input for approximately 30 minutes.

Vertical or Horizontal Mounting: The NAD D 3045 can be installed vertically or horizontally. Eight self-adhesive rubber feet are included (the rubber feet add approximately 0.125" to the overall  height of the unit).

  • Vertical Dimensions: 2.8125" (w) x 9.3125" (h) x 11.375" (d)
  • Horizontal Dimensions: 9.3125" (w) x 2.8125" (h) x 11.375" (d)

The USB input is not deigned or tested for use with iPhones or iPads.
zachary  Jul 30, 2023 (Staff)
The Details page/manual states there is a high-pass function (by pressing the BASS button on the remote) that will attenuate the output below 120 Hz/80 Hz/40 Hz. Is the pre-out/sub-out also attenuated, or is it just the speaker-level outputs?
bobby  Sep 19, 2021

If you have a subwoofer connected to the pre/sub out, then you can use the high-pass function to attenuate the low-bass sent to the speakers, but the full bass signal will, of course, still be sent to the sub-woofer. So I believe the pre/sub out is entirely unaffected by the high-pass function, it only controls the signal sent to the speaker outputs from this amplifier.
george  Sep 19, 2021
While I have used the application of Attenuation on my 3045 I never tried it in Pre /Power Mode , Sorry , Good Luck !
bruce c  Sep 19, 2021
Can this be connected to a pair of bookshelf speakers in front and another pair via bluetooth as rear? Will it have enough output to drive four speakers and a sub. Thanks.
abhishek  Oct 08, 2020

This integrated amp is intended to power one pair of speakers. It does have a preamp output that can be used to send audio to external amps as well as powered subwoofers. As for the Bluetooth, NAD references using it with headphones and expect that the amp channels will be turned off when its Bluetooth is being used to transmit audio.

Will it work if plugged into a 230 volt mains supply?
tiong  Feb 28, 2020

On the back of the unit it states: Power rating: 100-120/220-240V-50/60Hz 60W. This suggests that the unit can be plugged into both voltage systems and operate although I have not tried to run it when plugged into 230V source.
lukasz  Mar 14, 2020
It worked for me 220v here in Germany purchased from Crutchfield online. I would assume 230v will be fine but give it a last check before plugging into mains power.
daniel  Mar 14, 2020
I don't think so. Mine uses 120 Vac (somewhere between 110 and 120 actually). 230 seems to be a household supply voltage (phase to phase) incoming from the power company which is used on appliances like dryers and ranges. Most other household circuits should be around 115 Vac (phase to common).
jeff  Mar 14, 2020
I don't think so. It comes with a 120 plug (American).
philip  Mar 14, 2020
What version of bluetooth is this (4.2, 5.0)?
justin  Mar 15, 2019
1 answer
I do not know. I ended up returning it as it did not meet our needs (swapped up for Marantz 1609). It worked very well for our Bluetooth connectivity though. Reviews suggested a limited bluetooth range - didn't really figure that out as we changed our minds after a couple of weeks.
