    Users may choose to use the same size amplifier to power all components / passbands. o 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 o VT4880: users may choose to wire both 2258 (18”) components in parallel to one (1) channel of a an I-T amp 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.

  • Page 5: Notes Regarding Limiter Settings

    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.
