Whether at a club, a church or an outdoor festival, the ability to accurately and effectively control sound volume has always been challenging. Especially in today’s regulatory environment, it’s extremely important for proprietors to have a solution in place to prevent complaints and fines, and to protect their customers and sound system when an over-enthusiastic engineer decides to “crank it up.” The SPL3220 offers the ideal solution, providing dependable and seamless full-loudness control – without sacrificing the sonic integrity of the sound system, or listening pleasure of the audience.
Exceptional Sound Quality and Intelligibility
Thanks to onboard, multiband Interactive Gain Control (IGC) and Interactive Knee Adaptation (IKA) compression, the SPL3220 allows you to apply processing with surgical precision for maximum punch and intelligibility – without the audible artifacts associated with traditional, broadband dynamics processors. Additionally, the SPL3220 can be used for mix leveling and maximizing signal density at low volumes, where perceived loudness becomes even more important. Add to this the ability to enhance speech intelligibility and provide exceptional loudspeaker protection, while preserving dynamic range – and the SPL3220 becomes an essential part of every audio engineer’s toolkit.
Total Control is in Your Hands
Professional XLR/TRS combination and Euro block connectors provide the ultimate in versatility, allowing the SPL3220 to be inserted in-line prior to house amplification, no matter the system configuration. Built-in hard-bypass relays ensure system protection and signal continuity in the event of a power failure, or an accidental disconnect. High-accuracy I/O Level and Gain Reduction meters, plus an elegant and intuitive control panel make optimal system setup fast and easy. SPL3220’s control panel access cover can even be sealed to prevent unauthorized access, providing total system security.
