MixPre-3 II

The Strut STR-MP3 Custom-Fit Field Case for Sound Devices MixPre-3 is a small-footprint, lightweight padded case for location work. It has a removable rain top with a clear vinyl window that can also function as a sunshade or converts to a travel cover. The travel cover has no logo for added security.

The STR-MP3 offers a padded main compartment for the recorder and a front pocket that is useful for both RX and FX work. In RX mode the lid rolls back out of the way of antennae and gives a clear view of read-outs. The RX Pocket is built to hold up to four wireless Sennheiser G4 or similar-sized receivers,(fits three receivers if using BDS in one of the available spaces). The pocket has a wiring port into the main compartment. For FX work, deploy lid to cover accessories such as AC adapter, cables, batteries, or a handheld mic.

This case can accommodate 4 and 8 x AA sleds, or NP-F battery sled options, or NP-1, Remote Audio, and various USB-C type power banks. The case features double belt loops and 4 harness attachment points for most audio harness systems. It includes an HAR-2 chest harness. Made in the USA
