Prima LT Plus

Our new Prima LT is the fastest selling codec ever. You love the easy-to-use interface, the full compatibility with other codecs, and the unprecedented 24-bit audio. Now, the Prima LT Plus gives you even more. 

The new Prima LT Plus starts with all the features you love in our Prima LT—and then adds more! Four oversize VU meters, intelligent headphone monitoring, room for three ISDN or other digital interfaces, SMPTE Time Code, up to eight relay functions, two Ancillary Data channels, and the full feature set of Prima Program Language. All in an easy to operate package. 

Prima LT Plus gives you unmatched capability in an easy-to-use package!

The Prima LT Plus offers the same superb audio specifications as our CDQPrima™ line of codecs. With the enhanced MPEG Layer 2, MPEG Layer 3, and G.722, Prima LT Plus gives you ISDN connectivity at bit rates ranging from 56 to 384 kb/s. Bit rates from 24 to 384 kb/s are supported with other digital transmission facilities. The microprocessor-controlled Prima LT Plus is equipped with powerful programming functions. Using Prima Logic Language, you can program your Prima LT Plus to perform functions such as Automatic Call Configuration and Automatic Algorithm Detection.

Prima LT Plus uses plug-in modules to allow you to connect directly to ISDN or to any digital transmission system with available V.35, X.21, RS530 or RS422A interfaces. Independent Mono mode allows you to send two independent mono audio programs to any combination of six locations.

Other features include:
