A stereo headphone amplifier for recording and livesound. Different to most comparable models the overall gain may be altered with the aid of internal jumpers to better match specific headphone characteristics. Due to this technique, this headphone amplifier is able to drive nearly all existing headphones from 8 … 600 Ohms load impedance. Because of its noise- and THD-optimized circuitry layout, G103-P MKII covers high quality demands. In spite of its compact dimensions, G103-P MKII offers optimum flexibility and high power. Reliability even under rough or improper handling conditions has been another important goal of development. Thus, the unit is absolutely long-term short-circuit proof. In addition, the G103-P MKII is equipped with filters to prevent overload by inaudibly low and high frequencies.
