iFi Audio ZEN Air Blue 2

This Bluetooth DAC iFi Audio ZEN Air Blue 2 allows you to add wireless connectivity to a hi-fi system, a car stereo or a battery-powered setup. It is aimed at users wishing to transmit audio from a compatible source, with broad support for Bluetooth codecs and an analog RCA L/R output. The product is based on Bluetooth 5.4 technology and a Qualcomm QCC3095 chipset. It supports aptX Lossless, LDAC, aptX Adaptive, aptX HD, aptX, AAC and SBC formats. Its architecture separates Bluetooth reception, digital-to-analog conversion and amplification functions, with a Qualcomm chipset, an ESS Sabre DAC and custom operational amplifiers. The stated frequency response covers 10 Hz to 20 kHz at 44,1 kHz and 20 Hz to 40 kHz at 96 kHz. The output delivers 2,1 Vrms at 0 dBFS, with an output impedance less than or equal to 51 Ω.

In use, this Bluetooth DAC makes it possible to modernize a limited installation or one without wireless connectivity. Compatibility with multiple codecs makes it easy to pair with different source devices, while aptX Lossless targets CD-quality transmission when the source is compatible. The DC 5-12 V power input allows integration at home, in a vehicle or in a battery-powered configuration. In automotive use, the device can turn on automatically when the engine starts. Its physical power button allows you to control power-on and pairing depending on the usage context.
