Introduction
Owner’s Reference GCHA Headphone Amplifier
Thank you for your purchase of the PS Audio GCHA Headphone Amplifi er.
The GCHA is a
The GCHA contains a Gain Cell’s preamplifi er stage and a Class A biased output stage. The GCHA can accept audio signals from any analog source or digital audio from your
A unique feature of the GCHA is the volume control itself: which does not attenuate the audio signal in the tradional manner, rather, the level of the GCHA is adjusted by controling the gain of amplifi ers inside the GCHA.
In a traditional headphone amplifi er, an audio signal is presented to the amplifi er at full signal level. The headphone amplifi er then attenuates, or reduces, that input signal to reach the desired listening level with headphones. While this conventional method of controlling the volume is an acceptable practice, it does have drawbacks: the attenuators cause degradation of the audio signal. The GCHA solves this problem by use of the PS Gain Cell technology. Gain Cells have adjustable gain and need no attenuation of the input signal to achieve desired listening levels. Instead, the front panel volume control is a gain adjustment, rather than an attenuator. The removal of any attenuators in the signal path has a sonic advantage over conventional technologies.
You should expect unrivaled sonic qualities, with low noise, high performance audio being delivered to your headphones.
