Improve dynamics and headroom for more accurate sound from your DX240 with the AMP8 MKII balanced amp card. Main Features: +/-8V high voltage swing. This significantly improves dynamics and headroom, resulting in a more accurate sound that is true to the recording. AMP8 is a completely new circuit design that is dedicated to the DX150/DX200 and features both a high voltage and current output. High current output is very useful for low impedance multi-drivers in ear monitors. Low VCE transistors are utilized and are manually sorted and paired, providing better consistency and linearity. The low VCE also expands the linearity range. The transistors used on the buffer stage have a 2700mAh output current rating, which allows the AMP8 to drive IEMs and headphones that require high current with ease. A Pentaconn 4.4.mm balanced output port is used. The large double contact area of this socket contact lowers resistance and allows better current transmission.
