The G103-P MKII is a stereo headphone amplifier for recording and live performance. Unlike most comparable models, the overall gain can be altered using internal jumpers to better match the specific characteristics of the headphone. Thus, the G103 is capable of driving almost all existing headphones with a load impedance of 8 to 600 ohms. Thanks to its noise and THD optimized layout, the G103-P MKII meets high requirements for sound transparency.

Despite its compact dimensions, the G103-P MKII offers great flexibility and high power. Another important goal in the development of the 103 is reliability, even under difficult conditions. Thus, the device is absolutely resistant to long-term short circuits. Additionally, the G103-P MKII is equipped with filters to prevent overloading by low and high frequencies located outside the audible spectrum.

The G103-P MKII's body is made from black anodized aluminum, including the front and rear panels. This provides it with high mechanical stability and resistance to rough handling. Package surfaces provide excellent electrical conductivity for optimal EMC characteristics.

The mains cable may vary to suit the requirements of different markets. The device is factory set to a mains voltage of 230 V AC.

The mains voltage can vary between 190 and 250 without any impact on perfect operation. Integrated mains transformers provide internal supply voltages of approx. +/- 25V.
