8 - PRESETS LIBRARY

The A6 preset library includes standard array, small array (SA), and fill (FL) operating modes. VTX presets are exclusively developed for

Crown I-Tech HD amplifiers and come bundled with Performance Manager control software. Audio Architect

and can be downloaded from www.jblpro.com. Below is a description of A6 operating modes and subwoofer processing options. Refer

to the Preset Library setup sheets for preset descriptions, memory locations, and output channel assignments.

Three preset modes are available:

VTX A6 FL 80: The FL preset (short for FILL) has nominally flat frequency response and used in situations where individual A6 cabinets

are appropriate, such as distributed front fills or under-balcony fills. With this preset, the acoustical low frequency response of the sys-

tem extends down to 80 Hz.

VTX A6 SA 80: The SA preset (short for Small Array) is appropriate in situations where two or three A6 cabinets are used. A gentle high

frequency shelving response is applied to offset LF/MF array buildup for small arrays. With this preset, the acoustical low frequency

response of the system extends down to 80 Hz. Use this preset when A6 cabinets are placed on a pole on top of subwoofers.

VTX A6 80: This is the standard VTX A6 preset for use with arrays larger than three cabinets. A high frequency shelving response is

applied to offset LF array buildup for nominally focused arrays (equally spaced impact points over the desired audience coverage area).

This mode is compatible with the Array Size Compensation filter, which can further shape the array buildup depending on array length.

With this preset, the acoustical low frequency response of the system is set to 80 Hz.

The A6 presets are compatible with all VTX B-Series subwoofers including the B15, B18 and B28. VTX subwoofers support 60 Hz and 80

Hz modes which can be selected depending on the full-range speakers used. In the case of the A6, the 80 Hz presets must be selected.

VTX BXX 60: The 60 Hz preset mode extends the upper frequency response of the subwoofer to 60 Hz. The 60 Hz preset is normally

employed when VTX cabinets are used in full-range mode.

VTX BXX 60 REAR: The 60 Hz rear preset was designed to work in conjunction with the standard 60 Hz preset to drive rear-facing

cabinets in cardioid configurations.

VTX BXX 80: The 80 Hz preset mode extends the upper frequency response of the subwoofer to 80 Hz. The 80 Hz preset is normally

employed when VTX full-range cabinets are set to 80 Hz.

VTX BXX 80 REAR: The 80 Hz rear preset was designed to be work in conjunction with the standard 80 Hz preset to drive rear-facing

cabinets in cardioid configurations.

TIP: The VTX A6 presets provide a well-balanced tonal starting point for a given array size. The Array Size Compensation

filter found in the JBL Line Array Control Panel (LACP) can be used to further fine-tune the tonal balance of an array for a

given size and shape.
