The AirLens™ interface brings perfection to streaming

Streaming audio via Roon or other services like Qobuz, Tidal, and Spotify offers millions of titles at the touch of a finger.

Unfortunately, connecting your sensitive DAC to the noise generated by computers, routers, NAS, local networks, and modems via either WiFi or Ethernet cable is not a great-sounding solution to bringing high-performance audio into your listening environment.

The PS Audio AirLens™ completely eliminates the problems of noise, jitter, and EMI influences through complete galvanic isolation and perfect reclocking of the digital audio signal.

You have not yet heard how great streaming can sound until you experience audio through the AirLens.

Design

Whether you stream network music through Roon, Audirvana, JRiver, Tidal Direct, Spotify, your NAS, or any DLNA-compatible server, you will introduce unwanted noise into your sensitive DAC.

A USB connection to the computer is by far the noisiest method, followed by a close second via Ethernet or WiFi.

What is needed to completely remove this injurious noise is the elimination of any electrical connection between the computer, its network, and your DAC.

The PS Audio AirLens has both an input stage and a galvanically isolated reclocking output stage.

The two are connected only “through the air.” By using separate power supplies, there are no physical ground or signal connections, ensuring 100% isolation and noise-free delivery of perfect digital audio signals

Application

Eliminating the noisy USB to-computer connection and instead placing the PS Audio AirLens between your home network via Ethernet or WiFi will change forever the performance of streaming music.

Once connected to any DAC, the AirLens interface will bring exceptional transparency, resolution, timbral realism, and wide dynamics to any D to A converter.

Noise from any number of sources including your computer, long runs of Ethernet cable, EMI interference through WiFi, the system modem and router, all contribute to increased jitter and a general reduction of fidelity in the system.

Connecting your DAC via its coax or I2S inputs completely removes the haze and congestion caused by these noise sources.

Galvanic Isolation

Galvanic isolation means the complete elimination of any physical electrical connection between input and output.

Typically, a common power supply provides ground and power to both inputs and outputs.

Once a non-galvanically isolated device is connected to a noise source at its input, its shared ground passes the noise through a common ground to the output stage where the DAC is connected.

The challenge with the AirLens was to design two fully isolated stages: input and output, and connect the digital audio signal between the two without any loss.

To do this PS Audio have incorporated a low-noise galvanically isolated DC-to-DC converter to feed power to the AirLens’ output stage.

They then deliver the received digital audio data to that clean output stage using only air as the interface.

The results are nothing short of amazing.

Finally, streaming music with all the noise and jitter-induced haze and congestion gone.

Digital Lens Technology

Digital audio signals rely upon critical stability in timing to sound their best.

Relying upon the clock in your computer or the clock inside of a streaming interface is typically less than ideal.

As network musical data enters a computer or streaming interface there is no clock associated with the data.

Once collected, the master clock must be added so that your DAC can function properly.

Inside the AirLens is our famous Digital Lens technology.

Based on a variable RAM buffer, the data is collected and stored before being sent out to the DAC by a high-precision, low-jitter fixed clock.

This reclocking of the data coupled with the elimination of noise provides to your DAC the cleanest low jitter digital audio signal possible.

The results are stunning. Suddenly, streamed music rivals that of local music from your transport.

Experience the difference from the AirLens.

What can you expect

Whether you choose your streamed music through Roon, Audirvana, JRiver, Tidal Direct, Spotify, or any DLNA-compatible source (like your NAS), the addition of the PS Audio AirLens between the network and your DAC will set a new standard of musicality.

Simply connect your network to the AirLens through Ethernet or WiFi, then your DAC to the AirLens through either coax (RCA) or I2S (via an HDMI cable) then sit back and be amazed.

The AirLens connects any DAC to the outside world via your home network and protects your sensitive DAC from any unwanted noise from cables, computers, and WiFi.

The AirLens will handle PCM up to 384kHz, and DSD up to 256 (4X) in DoP or native.

The world of streaming just took a major leap forward in sound quality.

We cannot wait for you to experience all that streaming has to offer.
