The Pro-Ject Head Box S compact headphone amplifier is designed to drive models of any standard impedance. The device is made in a metal case of small height, and it is easy to find a place for it on a desktop or in a rack for AV equipment. On the front panel of the device, made of brushed aluminum, there is a power button and a blue indicator LED, a large volume control knob, and a high-quality jack for connecting stereo phones with a diameter of 6.3 mm. exit, working as a "transit". This solution allows you to save the output of the amplifier (for example, intended for connecting a recorder) for connecting other devices, which is especially valuable if your amplifier has only one such output. The device is made using selected components, and its printed circuit boards are optimized by computer modeling to reduce the length of the conductors. The amplifier is powered by an external power supply, and, if desired, music lovers can replace it with another one - for example, increased power, or with other » characteristics. The Pro-Ject Head Box S delivers noticeably better sound quality than the amplifiers built into high-end CD players due to greater detail and a wider frequency range. Even when connecting headphones with a resistance of 300 ohms with not the highest sensitivity, the level and quality of the bass remains consistently high, and the sound at mid frequencies is natural and uncolored. The amplifier works great with a PC, including when connected to the headphone output of laptops. Thanks to the optimal input impedance and gain, the sound remains transparent, without signs of congestion or any distortion. Thanks to the small dimensions of the Pro-Ject Head Box S, you can take it with you on trips if you do not want to part with your favorite music when you are away from home. The external finish of the amplifier case can be black or silver.
