AMP7 is a complete new discrete circuit design that based on our four channel architecture 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. +/-8V high voltage swing. This significantly improves dynamics and headroom, resulting in a more accurate sound that is true to the recording. The transistors used on the buffer stage have a up to 2700mA output current rating, which allows the AMP7 to drive IEMs and headphones that require high current with ease. Specification Phone Out: Output Voltage: 3.2Vrms Frequency Response: 10Hz-45KHz +/-0.3dB S/N: 122dB THD+N: 0.00023%, -113dB (no [email protected]) 0.00023%, -113dB (300Ω@1.8Vrms) Output Impedance: 0.3ohm DNR: 122dB Crosstalk: -106dB Line Out: Output Voltage: 3.2Vrms Frequency Response: 10Hz-45KHz +/-0.3dB S/N: 117dB THD+N: 0.00023%, -113dB (no [email protected]) DNR: 117dB Average Play Time: 7.5hours (Play time varies with different sample/bit rates, volume and headphone/IEM loads.)
