The iFi Audio ZEN Air Blue 2 is a high-quality Bluetooth receiver designed to add modern wireless audio playback to an existing amplifier, receiver or pair of powered speakers. You can continue using the hi-fi system you already enjoy while streaming music conveniently from a smartphone, tablet or laptop.
Bluetooth 5.4, aptX Lossless, LDAC and a separate ESS Sabre DAC provide a stable connection and carefully managed digital-to-analogue conversion. The analogue RCA output connects directly to a free line input on an amplifier, receiver or compatible powered speaker system.
The ZEN Air Blue 2 forms part of the accessible iFi Audio range and is intended for music enthusiasts who want to combine Bluetooth convenience with a considered hi-fi signal path.
Standard Bluetooth audio is often associated with additional data compression. The iFi ZEN Air Blue 2 therefore supports several advanced codecs. With a compatible source, aptX Lossless can transmit 16-bit/44.1 kHz CD-quality audio without losing audio data. The codec used in practice is automatically determined by the capabilities of the connected smartphone, tablet or computer.
For devices without aptX Lossless, the ZEN Air Blue 2 also supports LDAC, aptX Adaptive, aptX HD, aptX, AAC and SBC. LDAC can receive high-resolution audio up to 96 kHz when used with suitable source equipment. This allows the receiver to select the best Bluetooth quality jointly supported by both devices.
Many basic Bluetooth adapters use one combined chip for reception, conversion and analogue amplification. iFi Audio gives the most important stages of the ZEN Air Blue 2 their own dedicated components.
A Qualcomm QCC3095 chipset processes the incoming Bluetooth signal. A separate ESS Sabre DAC then performs digital-to-analogue conversion, while custom OV-series operational amplifiers handle the analogue output stage. The iFi GMT clock system helps reduce timing errors and jitter. This architecture is designed to preserve more detail, stability, dynamics and clarity than a basic all-in-one Bluetooth adapter.
The ZEN Air Blue 2 features an analogue stereo RCA output. Connect it to a free AUX, CD, Tuner or other line-level input on your amplifier or receiver. It can also be connected to powered speakers equipped with a suitable analogue input.
Your amplifier or speakers do not need to have built-in Bluetooth. The ZEN Air Blue 2 receives the wireless signal and converts it into an analogue stereo signal for your existing system. Explore our complete range of Bluetooth audio receivers for alternative wireless solutions.
Support for a 5 to 12-volt DC supply means that the ZEN Air Blue 2 is not restricted to home or office use. With a suitable and correctly connected power supply, it can also be integrated into a car, camper, caravan or boat.
In a compatible vehicle installation, the receiver can power on and shut down automatically with the engine and electrical supply. Always use a suitable regulated power supply with the correct polarity and connector.
The ZEN Air Blue 2 is the best choice when you need an affordable, high-quality Bluetooth receiver with an analogue RCA output. It focuses specifically on receiving and converting wireless audio.
Do you also need Bluetooth transmission, digital inputs, USB DAC functionality or a balanced analogue output? Consider the more versatile iFi Audio ZEN Blue 3. The ZEN Blue 3 offers more connection options, while the ZEN Air Blue 2 remains an excellent solution for adding wireless playback to an existing amplifier.

Yes, provided the amplifier or receiver has a free analogue line-level input such as AUX, CD or Tuner. Connection is made with a stereo RCA cable.
Yes, provided the powered speakers have a suitable analogue line input and their own volume control.
No. Both the ZEN Air Blue 2 and the transmitting device must support aptX Lossless. When this is not the case, another codec supported by both devices is selected automatically.
No. This model receives Bluetooth audio from a phone, tablet or computer. For a device that can both transmit and receive Bluetooth audio, consider the iFi Audio ZEN Blue 3.
No. The ZEN Air Blue 2 has an RCA line output rather than a headphone output. Connect it to an amplifier, receiver, headphone amplifier or powered speakers.
A USB-to-DC cable is included. A separate USB mains adapter is not part of the standard package contents.
