How do I use THX Onyx?
THX Onyx works right out-of-the-box with 3.5mm headphones and headsets with no drivers to install. Just plug and play! If you’d like to optimize your settings, we have several user guides and resources here.
Note THX Onyx for iOS requires the slim Apple Lightning to USB Camera Adapter (sold separately). All other Lightning adapters are incompatible, including the wide Apple Lightning to USB 3 Camera Adapter.
How will a DAC amp improve my sound?
Using a THX Onyx DAC-amp improves the sound quality in several ways over a stock 3.5mm headphone jack or adapter.
THX Onyx increases the output power and voltage available in your headphones to a full two volts, with enough current to drive power hungry headphones with as little as 22 ohms impedance to an impressive 180 milliwatts per channel. Having so much power on-tap provides listeners with a superb dynamic range to make spines tingle and emotions soar when listening to the pure audio output.
THX Onyx achieves this high output power without creating distortion or noise in the signal. The THD+N of THX Onyx is a vanishingly low -112 dB (0.00025%), and the output impedance is a small <0.2 Ohms to resist non-linearities in the headphones and cabling. This lack of distortion and noise makes for an enthralling, fatigue-free listening experience. You’ll be listening to your favorite songs on repeat in audio bliss.
What is a DAC amp?
A THX Onyx DAC-amp is a two-in-one product that delivers a pure headphone audio fidelity experience. First, the DAC or digital-to-audio converter, receives the digital audio stream from your smartphone or laptop and converts it into a stereo analog audio signal. Next, the THX AAA amplifier increases the voltage and current of this analog signal to push it powerfully into your headphones with very little output impedance so the headphones remain well-controlled.
Where Can I Get High Resolution Audio?
Streaming high resolution audio is here, and it’s the pure sound you’ve been seeking! Top high res streaming services include Tidal HiFi, Amazon Music HD, and Qobuz. Alternatively, purchase and download your own high res audio from hdtracks.com for bit-perfect playback with favorite apps such as Vox, USB Audio Player Pro, Roon, Audirvana, Foobar2000, Onkyo HF Player, and more.
