• Users may choose to use the same size amplifier to power all components / passbands. • DSP crossover presets provided by JBL assume that the same amplifier models with equal voltage gain, are used for each bandpass. -
Page 4: Subwoofer Wiring Notes
NOTES ON SUBWOOFER WIRING • VT4880: Users may choose to wire both 2258 (18”) components in parallel to one (1) channel of a MA-3600 or MA-5002 for (4) ohms load. In this case each amplifier channel drives one VT4880. If two VT4880 are wired in parallel, the load is two ohms and there will be no amplifier power headroom. -
Page 5: Limiter Settings Notes
NOTES REGARDING LIMITER SETTINGS • The recommended limiter threshold settings provide 3 dB of headroom before the component or bandpass peak voltage is reached. • The component or bandpass peak voltage is 6 dB above the voltage used at continuous maximum power. •... - Page 6 Amplifier Configurations: 4 x VT4887 & 2 VT4881 / 3 MA- 5002 Amplifier Power Power Bandpass Nominal Limiter Amplifier Speakon NL8 Rating at Available to Peak Driving Impedance Threshold Channel Terminals Nominal each Voltage at Pins Impedance Bandpass 4 x 2407H Ch 1.

Page 17: Vertec: System Suspension Hinge Bars
VERTEC SYSTEMS: SUSPENSION HINGE BARS High-grade steel alloy hinge bars are used to couple adjacent boxes together. There are several different types. To ensure ease and proper inter-connection, make certain that the correct hinge bar model is matched to the appropriate Array Frame or Short Frame as well as the correct V model. -
