Loudspeaker power ratings shown below are continuous. Please refer to the JBL VLA spec sheet for details concerning the power rating. Amplifier ratings are full range at 0.1% distortion. The following are general guidelines. VLA (standard power) - Crown Itech/Macro Tech version Band LF MF HF Transducers 2x 2226H (15") 2x CMCD82H 3x 2431H Wiring configuration parallel parallel series nominal impedance 4 4 16+ power handling 1600 700 225 recommended amp (1/2) MA-5000i/IT-5000HD (1/2) MA-5000i/IT-5000HD (1/2) MA-5000i/IT-5000HD amp power rating 2500W -> 4 ohms 2500W -> 4 ohms 1250W -> 8 ohms VLA (standard power) - Crown CTs version Band LF MF HF Transducers 2x 2226H (15") 2x CMCD82H 3x 2431H Wiring configuration parallel parallel series nominal impedance 4 4 16+ power handling 1600 700 225 recommended amp (1/2) CTs3000 (1/2) CTs2000 (1/2) CTs2000 amp power rating 1500W -> 4 ohms 1000W -> 4 ohms 1000W -> 8 ohms VLA-H (high power) - Crown Itech/Macro Tech version Band LF MF HF Transducers 2x 2226H (15") 4x CMCD82H 6x 2431H Wiring configuration parallel series-parallel series-parallel nominal impedance 4 8 4 power handling 1600 1400 450 recommended amp (1/2) MA-5000i/IT-5000HD (1/2) MA-9000i/IT-9000HD (1/2) MA-5000i/IT-5000HD amp power rating 2500W -> 4 ohms 1500W -> 8 ohms 2500W -> 4 ohms VLA-H (high power) - Crown CTs version Band LF MF HF Transducers 2x 2226H (15") 4x CMCD82H 6x 2431H Wiring configuration parallel series-parallel series-parallel nominal impedance 4 8 4 power handling 1600 1400 450 recommended amp (1/2) CTs3000 (1/2) CTs3000 (1/2) CTs2000 amp power rating 1500W -> 4 ohms 1250W -> 4 ohms 1000W -> 8 ohms DSP settings including crossover, equalization, and limiter settings are available for insertion directly into I-Tech HD, PIP USB3 cards and BSS London. Limiter settings are available for all Crown amps. It is highly recommended that an amplifier control system is implemented to monitor and control the amplifiers for these systems. Due to differences in DSP topology and the sensitivity of the boxes to misalignment, other DSP systems are not recommended. Summary Combining JBL technologies from both the VerTec® and the Precision Directivity® lines, the development of the JBL VLA SERIES line provides the designer with new and unique options for system design. VLA systems already implemented have consistently exceeded performance expectations. 19
