ROG Xonar Phoebus
ROG ThunderFX
Besides being famous for its motherboards, the Republic of Gamers team at ASUS also dabbled in gaming accessories like keyboards, mice and headsets (ROG Vulcan)
The ROG Xonar Pheobus (god of music and light) is a standalone product rated at 118db SNR at its regular outputs and has a dedicated amplifier for driving up to 300ohm headphones. Also included in the package is a volume control/wire extender for gaming headsets
Back of the PCB
We noticed that the Pheobus has an unusual amount of ports at its I/O panel (from top: headset connectors, power for the volume control, line-in, 5.1 audio amd SPDIF-out)
After removing the metal shroud, the layout is fairly crowded and components doen't look too different from the usual Xonar offerings. One notable inclusion is a 6-pin PCIe power connector (probably for the amplifer), which is not normally used for audio applications
High quality gold plated jacks are used at the I/O panel
Over at the bottom right, we can see the C-Media DSP which is normally used on the other high end boards like Xonar STX
Elsewhere on the board we found a Realtek ALC889 codec, which we guess handles the headphone output and microphone input
ROG ThunderFX
The ROG ThunderFX is a external USB follow-up to the acclaimed ROG Thunderbolt audio that was bundled with the Rampage III Extreme Black Edition and selected editions of the Crosshair V Formula
Front View - The ThunderFX actually allows for selection of multiple inputs (PC, Xbox360 and PS3) and different audio presets for various scenarios.
At the back, we see RCA left/right audio connectors for input and USB for power and PC sound card connectivity
Sneak preview of the software - uses the red ROG colour scheme and looks similar to the older Thunderbolt's interface
