Empirical Labs Powergrid DUO

The PowerGrid Duo is a compact 2-slot chassis designed to house your favorite 500-series modules in a standard 19” rack. Its recessed slots accommodate virtually any module, while rear-panel balanced XLR and ¼” TRS I/O make integration straightforward. A rear Stereo Link switch allows for easy stereo operation or flexible routing between modules.

With up to 300 mA of stable current per rail, the PowerGrid Duo ensures consistent performance across both slots. Each position features a dedicated ground-lift switch to eliminate hum and grounding noise, keeping your signal clean. At only 1RU tall, this chassis is an efficient solution for expanding your rack with 500-series processing.
