Never heard of ATI?  They've been building high quality, bulletproof gear for the Broadcast industry for more than 30 years.  bibbtek has been installing their products in places ranging from Edit suites and Audio Production Studios to Conference rooms and School Auditoriums, with a remarkably low failure rate.

We love this stuff.   This gear is very well constructed and designed by folks who know the business of delivering high quality audio dependably, in high RF environments without compromise.

We have DAs that remain in continuous service that were installed in 1981!

The MM100 interface is a high end  Pro level converter.  It provides Bidirectional conversion of IHF (-10 db) and Pro (+4 db) signals.   This box ouputs active Balanced +4 db levels for use in either Pro recording environments or high end audio systems .   It provides excellent isolation with 4  level controls and Gold plated RCA jacks.

If you have a recording studio where you are trying to integrate consumer gear with pro equipment this is what you want to use.  These boxes offer lots of headroom, with excellent bandwidth.   If you want to get the job done right the first time, an active coupled interface is the way to go.

The best technique is to place these units close to the unbalanced Source/destination and run balanced cable to your patch panels or console.

The MM100 can also be used to integrate Balanced Pro gear for use in unbalanced consumer systems while correcting level mismatches and providing good ground isolation.
