The Sound Devices MX-HIROSE is a Hirose DC input sled designed to help power compatible Sound Designer recorders. This can aid in powering units in the original MixPre series, the MixPre-M series, and the MixPre-II series.

With most compatible recorders, releasing the MX-HIROSE is as easy as pressing the release tab. However, on the MixPre-10 II, a flat head screwdriver will be necessary. Set your MixPre's power source internally to the NiMH option before use. When connecting the MX-HIROSE to the original MixPre units, Sound Devices recommends making use of a right-angled Hirose connection.
