HiQnet

 Software

The Crown VRack has a unique advantage when used with Harman's HiQnet System Architect software.  

The software is able to literally 'see' that your iTech4x3500HD amplifiers are in a rack, and specifically 

they're in a VRack.  You get specific advantages in speeding up deployment, programming, tuning, and 

monitoring of a VRack powered system.

In addition, the user can combine the presets in all 3 VRack ampmlifiers into a single 'VRack Preset'.  This 

is done by loading the individual preset into each amplifier, and then using the VRack control panels' 

'Preset' tab to save each individual preset into the same preset memory location on each amp.  Now with 

a single click, an 'entire rack' setting can be recalled.  For most sound companies this means that with an 

initial investment of some time in the shop, single-click 'entire rack' settings can be configured for most 

of the PA in inventory, eliminating the need to program and recall individual presets in the field.  

See page 42 for details.
