Description

The Radial SixPack is a dynamic addition to your studio that allows you to mix and match up to six 500 series modules to customize your sound. This desktop power rack is not only designed to power your modules but also allows you to connect them in a complete signal chain. The design begins with a durable 14-gauge steel construction and baked enamel finish, offering better shielding against stray magnetic fields, and ensuring extra durability for studio mobility.

The double sided EDAC 15-pin receptacle ensures a solid connection, compatible with the old API pin format. The SixPack boasts a whopping 1600 milliamps of shared current, providing over 265 milliamps per slot, satisfying even the most power-hungry tube modules. The rear panel connectivity includes individual XLR input and output connectors wired in parallel to ¼” TRS connectors, offering versatile cross-patching opportunities.

A unique feature is the Omniport, a ¼” TRS jack that adds extra functionality. Two front-mounted XLR connectors are routed to the D-Sub or to inputs 1 and 4, making patching in a microphone an expedient task. The SixPack isn't just a power rack, it’s a creative tool that lets you design your own unique signal paths.
