Pro Audio

Jensen Iso-Max pro-isolators present a complete range of passive, hum-eliminating solutions for balanced and unbalanced signals where absolute audio performance is required. These feature ultra-wide frequency response, exceptional signal handling (up to +24dB) and immunity to external electromagnetic fields.  Built into an easy-to-install flanged outer shell, each model comes equipped with standard connectors or may be special ordered to suit. Also included is a terminal strip for greater connectivity plus a set & forget bottom-mount dip switch to optimize each setup to suit your specific installation. This makes the Jensen Iso-Max professional ground isolators well suited for broadcast, recording, live touring and the most demanding audio installations.
