Lake People Phone-Amp G103D4 is a headphone amplifier intended for DANTE networks.The G103D4 model comes with a DANTE 4/4 input and two independent stereo amplifiers. 24 Bit / 192 kHz D/A converters with a Signal-to-noise ratio >105 dB and THD+N as low as 0,002 % are driving the powerful headphone amplifiers. These are best suited to drive any headphones from low to high impedance and with low or high sensitivity. To adapt the amp to demanding headphones, to further reduce the noise level or to maximize the travel of the volume control, the gain is internally adaptable by Dip-Switches to optimize the amp;The DANTE digital audio signals are input via a standard RJ45 connector. Lake People G103D4 will accept 4 audio channels. The unpacked audio signals are input to two high quality D/A converters. The recovered analogue signals are buffered, attenuated in the analogue domain and then sent to powerful headphone amplifiers.If required, additional gain of +6 dB or +12 dB can be set by Dip-Switches inside the amp. Each amp section offers a 1/4” and 3.5 mm phone jack which may be used simultaneously.Power supply for the amp is acomplished either by PoE (Power-over-Ethernet) or by a USB wall plug adaptor (not supplied) with USB-B or USB-C connector. The case, front and backpanel of G103D4 is made of rugged black anodized aluminum, the lettering is laser engraved. The volume knobs are also made of solid aluminium.
