Translated From Chinese "M17 uses the same four-way THX788+ amplifier circuit as the K9Pro, and the output power is very strong. It is a real portable computer. Because of this, if it is in the DC power supply mode, due to the high working voltage of the amp circuit, when paired with some headphones that require high voltage and high current, the M17 will be more portable than common when playing dynamic and strong songs under long-term high volume. The equipment is quite tall. So we specially designed this cooling bracket with fan to cool down. There are two optional wind speeds, and there is enough space at the bottom for wiring. In addition, unlike other portable devices, M17 comes standard with this heat dissipation bracket and a high-power DC power supply (fast charging is not supported). It also fully demonstrates the extraordinary features of M17. When posting this Weibo, some netizens are interested in this fan bracket, so I will explain the ins and outs. Because it is designed for M17, the size structure is not very suitable for other models, but if there are many people in demand, we can still put into production a relatively general heat dissipation bracket."
