Radial Engineering


The Powerhouse is a ten module rack designed to accommodate all 500 series modules. Powered by a 1,600 milliamp shared power supply, the Powerhouse is well equipped to handle current hungry tube modules. And as with all Radial power racks, the Powerhouse has extra safety features to ensure stable and trouble-free powering. Each slot is equipped with XLR and ¼” TRS connectors for i/o and cross patching. The feed function eliminates the need to patch adjacent modules while the link switch enables stereo modules to be paired without having to pull out a solder gun. Front panelLEDS monitor the +/-16V rail supply along with the 48 volt phantom power feed. Construction is 14 gauge steel throughout for added durability and extra shielding.
