The "Lyrix" portable headphone amplifier is the affordable way to bring the world of high end audio to your headphones and portable audio player. The high supply voltage and the best rail-to-rail opamp on the market provide much better driving capacity than any portable player alone. Use this amp to power all headphones with impedance ratings of 16 to 350 ohms. Your ears will thank you!

Bass boost, Crossfeed, and Gain Adjustment Upgrades

The amp is one of the most featured portable amp available. It includes three front switches for bass boost, crossfeed and gain adjustment. Use the bass boost to improve low frequencies and thus making the music warmer. The crossfeed circuit images external loudspeakers in front of you. It makes stereo records with highly seperated left/right channels more natural. The gain switch allows you to adjust the internal gain of the amplification circuit. Use low-gain with in-ear-monitors and low impedance headphones (Grado phones) and high-gain with high impedance headphones like Sennheiser's HD650.

USB Connectivity

Furthermore, this amp includes an USB DAC (digital to analoge converter). The DAC acts as an external sound card of your computer. It installs itself without seperate software. Just connect the amp to your computer and enjoy your computer audio with much higher quality than standard sound cards! The amp is fully powered from USB port so there is no battery needed. A high quality voltage doubler makes it possible that you can even drive high impedance headphones just from the 5V USB port.

Battery Charging

The amp also includes smart battery charging technolocy. It will charge all NiMH or Ni-CD batteries and will not overcharge them. A controller circuit detects the charging status and stops charging when the battery is fully loaded (the green LED on the front indicates the charging status). This is far better than often used "trickle" charging that can overcharge your battery and damage it. The charging feature is detachable if you use non-rechargeable batteries. Note: The power adaptor is included. It suits for US, UK, Australian and European wall sockets. However, the battery is not included. We recommend you to purchase a 8.4V/250mAh (or higher) NiMH rechargeable battery from your local electronics store.
