DISC Behringer SPL3220 Stereo Multiband Sound Processor

Full Description

Precise Processing

With the inclusion of Interactive Gain Control and Interface Knee Adaptation compression, users are provided with outstanding tools for accurate processing. These tools can be used for mix leveling and for optimising signal density even at low volumes. Speech intelligibility ensures vocal performances, such as presentations, are crystal clear.

Versatile Control

The SPL3220 can be inserted into any system configuration with the professional XLR/TRS combo and Euroblock connectors. The integrated bypass relay constantly protects the system and signal in the event of a power failure or if a cable is accidentally disconnected. The incredibly accurate input/output level and gain reduction metres provide users with an easy method of monitoring their system.
