Frequently asked questions
Is the Vrack Minus Amps compatible with other Crown amplifiers?
Yes, the Vrack HD4 is designed as a chassis to house amplifier modules or work alongside separate amp units you already own. It provides power distribution and routing infrastructure but contains no amplifiers itself.
What is the total power output of the I-Tech 4x3500HD?
The I-Tech delivers 3,500 watts per channel across all four channels simultaneously at 2-ohm and 4-ohm impedances, totaling 14,000 watts of output power.
Which is better for a touring sound company with no existing amps?
The I-Tech 4x3500HD is the faster choice because it's a complete amplifier ready to deploy immediately. The Vrack Minus Amps would require you to source and install four separate amplifier modules first.
How do the cooling systems differ?
The I-Tech includes a global power supply with automatic thermal management in its 29-pound chassis. The Vrack Minus Amps provides built-in cooling and ventilation to support whatever amplifiers you install in it, but has no amplifier heat generation of its own.
