Lossless Bluetooth Receiver
The ZEN Air Blue 2 is a Bluetooth DAC built to bring lossless wireless audio into systems that were never designed for it. With Bluetooth 5.4, support for aptX Lossless and LDAC, and a dedicated three-stage internal design, it delivers CD-quality playback while keeping your existing speakers or amplifier in play. It fits easily on a desk, in a rack, or even in a vehicle—powered by flexible 5–12V DC input and ready the moment you are.
CD-Quality Bluetooth
Wireless audio has come a long way, and aptX Lossless pushes it into territory that used to belong strictly to wired connections. With bitrates up to 1,200kbps, the ZEN Air Blue 2 preserves the detail and dynamic range of CD-quality audio. Bluetooth 5.4 strengthens connection stability, reducing dropouts and keeping playback consistent whether you're across the room or moving between spaces.
Three-stage architecture that separates the work
Instead of relying on a single chip to handle everything, this DAC splits responsibilities across dedicated components. A Qualcomm QCC3095 chipset manages Bluetooth reception, an ESS Sabre DAC handles digital-to-analog conversion, and custom op-amps drive the output stage. This separation keeps noise low and signal integrity intact—reflected in measured performance like 109dB SNR and <0.005% THD+N.
Broad codec support for real-world devices
Not every phone or source supports lossless Bluetooth yet, and the ZEN Air Blue 2 accounts for that. Alongside aptX Lossless, it supports aptX Adaptive, aptX HD, standard aptX, AAC, SBC, and LDAC up to 990kbps. That range ensures you’re always getting the best possible audio quality your device can deliver without needing to change your source hardware.
Built for home and beyond
The addition of 5–12V DC input opens up more ways to use it. It integrates easily into car audio systems, boats, or other battery-powered environments without extra adapters. Whether it’s part of a living room system or mounted in a vehicle, it brings the same wireless capability wherever you listen.
Instant-on convenience with control
When powered in a vehicle, the unit turns on automatically with the ignition, so your music is ready without extra steps. A physical power button gives you manual control when needed, making it easy to manage pairing and playback in both fixed and mobile environments.
Simple analog output for easy integration
With RCA outputs delivering 2.1Vrms, the ZEN Air Blue 2 connects cleanly to amplifiers, powered speakers, or stereo receivers. Output impedance stays low at ≤51Ω, helping maintain signal quality across a range of downstream gear.
