Network Stereo Zone Amplifier: The 60-watt per channel, single-zone CI 720 V2 Network Stereo Zone Amplifier with HybridDigital amplification technology is the perfect addition to today's most advanced custom home audio systems. Featuring 60 watts per channel and powered by BluOS, an advanced high-resolution music management operating system, the CI 720 V2 allows you to access and stream 24-bit high-res music with the control of a smartphone or tablet via Ethernet and third-party control systems like Control4, Crestron, RTI and URC.

HybridDigital Amp Technology: With 60 watts per channel, and up to 165 watts of Dynamic Power on tap, the CI 720 V2's integrated HybridDigital amp can drive any speaker to lifelike sound levels without adding noise or distortion.

USB Port: The CI 720 V2 features a USB (type-A) port to directly connect a USB mass storage class (MSC) device; such as a thumbdrive or external hard-drive. The unit's USB port supports music playback from these compatible USB devices formatted in FAT 32. Not only can USB audio be played back on the CI 720 V2, but can also be wirelessly distributed to the rest of your Bluesound components throughout your home for multiroom playback.

Note: The USB port is not compatible with the direct connection of an Apple iOS or Android OS devices.

Analog & Digital Inputs: The CI 720 V2 also features both analog and digital inputs. There is one stereo RCA input and one optical (toslink) digital input. Both inputs support 2ch PCM audio (not compatible with Dolby Digital/DTS). Not only can the analog & digital input audio be played back on the CI 720 V2, but these inputs can also be wirelessly distributed to the rest of your Bluesound components throughout your home for multiroom playback.

Speaker Outputs: The NAD CI 720 V2 features a removable phoenix-style terminal block for its speaker outputs. You can connect one pair of speakers (4 or 8 ohm).

Sub Output: The CI 720 V2 features a mono-RCA subwoofer output for adding practically any powered sub (sold separately) with a line-level input and built-in low-pass crossover.

IR In: This 3.5mm input is connected to the output of an IR repeater (sold separately) or the IR output of another component to allow control of the CI 720 V2 from a remote location.

Thermostatic Fan Cooling: The CI 720 V2's highly efficient energy-saving amplifier and thermostatic fan cooling adds enhanced reliability.

Mounting Options: The CI 720 V2 can simply be placed on a shelf or be installed to a wall using the two keyhole-slots on the side of the network stereo zone amplifier. To facilitate mounting the CI 720 V2 in a rack, NAD offers the RM 720 Rack Mount Accessory (745RM720, sold separately). This useful accessory allows six CI 720 V2s to occupy a 3U rack space, providing a neat and tidy installation. The RM 720 also includes blanking plates for a neat front-panel when less than six amplifiers are installed.

Wireless Multiroom Audio

Bluesound Wireless High-Resolution Audio Eco-System: The NAD CI 720 V2 is part of the BluOS wireless high-resolution multiroom audio eco-system - consisting of powered speakers, soundbar speakers, amplifiers, players, and hard-drives. The BluOS wireless high-resolution multiroom audio ecosystem uses your home's wireless WiFi network to connect multiple Bluesound products and play your music in perfect sync, or different music simultaneously, anywhere in your home. BluOS can wirelessly transmit lossless music up to 24-bit/192kHz at ultra-fast speeds with no lag and zero loss in sound quality.

  • Compatible Multiroom Audio Sources: The following audio sources can be used for multiroom audio playback - internet radio (including TuneIn & iHeart Radio); online music services (including Tidal, Spotify, Amazon, Deezer, Slacker, and Napster); USB audio, music libraries (from computers and NAS drives); as well as hardwired analog & digital audio inputs..
  • Number of BluOS Zones: Up to 16 Bluesound devices can be connected in a strictly wireless environment. Demonstrated practice has shown that you can create up to 8 groups of 8 Bluesound devices or 4 groups of 16 Bluesound devices. If you want to connect more than 16 Bluesound devices, you will need to connect the Bluesound devices to your network using a wired connection. BluOS can then control up to 64 devices in a strictly wired environment.

Ethernet Jack: A wired Ethernet (RJ-45) connection is required to setup and operate the CI 720 V2 (no built-in WiFi). Using the supplied Ethernet cable, connect one end of the Ethernet cable to CI 720 V2's LAN port and the other end to the corresponding LAN port of your wired Ethernet broadband router.

Note: The NAD CI 720 V2 does not offer built-in WiFi for a wireless network connection.

BluOS Controller App: The free BluOS Controller app (for Apple iOS 9.3-up, Android OS 4.1-up, Windows XP-up, and Mac OS X 10.7-up) turns your mobile device or computer into a full-featured wireless remote control for the BluOS wireless multiroom audio system. The BluOS Controller app on your compatible device uses your home's WiFi network to connect with Bluesound devices, so you can play all the music you love anywhere in your home for a wireless multiroom music experience. Get on-demand access to your music libraries on your home network, stream live Internet radio from almost any place in the world, or listen to one of the many music services available on Bluesound, all from the palm of your hand with the easy-to-use BluOS Controller app.

  • Now Playing Screen: Control your music and adjust the volume in any room, get rich album artwork and detailed artist info, right from the Now Playing screen. Even check what quality you are streaming at to ensure the best possible listening experience.
  • Individual Songs & Playlists: Tap a song and have it play instantly, or create and edit playlists on the fly by simply adding songs or entire albums to the play queue. Playlists can then be saved inside the app and listened to at any time.

Alexa & Google Assistant Voice Control: The CI 720 V2's BluOS functionality will support Amazon Alexa and Google Assistant voice control through an over-the-network firmware update (now available). Using an Amazon Alexa or Google Assistant enabled device (sold separately - see Accessories Tab), you can use your voice to access your music libraries on your local network, select presets from online music services, control music playback functions such as Play/Pause/Skip, adjust volume levels, play music in different rooms, and even group rooms together. Each Alexa voice command will need to start with the phrase "Alexa or Google, ask Blue Voice to" or "Alexa or Google, tell Blue Voice to". Alexa and Google Skills for BluOS will need to be setup through the Amazon Alexa app (for Apple iOS 11.0+ or Android OS 4.4+) or the Google Home App (for Apple iOS 11.0+ and Android OS 5.0+ ).

  • The NAD network stereo zone amplifier does not feature a built-in microphone and requires a separate Alexa or Google Assistant enabled device (sold separately - see Accessories tab) for voice control.
