Installed Sound Products

The IS twelve two (122) series of loudspeakers are specifically designed for providing reinforcement in fixed installations where high sonic performance and flexibility in precise pattern control are critical. Precision designed with Mathematically Modelled Dispersion ™ the twelve two series provide exceptionally linear pattern control through crossover making the series perfect for critical applications. Self powered versions used in conjunction with K8 products provide a factory tuned and easily-managed reinforcement system for night clubs, auditoria, houses of worship, performance halls, arenas and stadiums.


Specs for 122 SP active backplate option

The self powered backplate shall provide digital signal processing, biamplification, factory set tuning and loudspeaker optimization, digital input compatible to K8 distribution standard; selector switch for K8 digital channel which can be overridden in remote software; +4 dBu nominal analog input on XLR female and terminal block connectors; wink LED for speaker identification; input overload LED for analog input; analog input level trim; remote monitored termination switch; remote control and monitoring of amplifier including termperature, load condition and performance.
