Frequently asked questions
Which is better for a touring sound company that owns multiple amp brands?
The Vrack is ideal because it's a chassis designed to accommodate your existing amplifiers and distribute power/signals without forcing you to standardize on one amp model. The 4X3500HDS only works if you want Crown amplification exclusively.
Do I need to buy amplifiers separately for the Vrack?
Yes. The Vrack Minus Amps is an empty 4-space rack chassis for power distribution, cooling, and AC management. You must populate it with your own amp modules. The 4X3500HDS arrives ready to amplify four channels of audio immediately.
What's the power output difference?
The 4X3500HDS delivers 4000W across four channels at 4Ω with integrated DSP. The Vrack has no built-in amplification—its power capacity depends entirely on which amps you install in it.
Which is better for a small venue that needs one amplifier solution?
The 4X3500HDS is the clear choice. It provides four channels, onboard speaker protection, and integrated processing in 2U. The Vrack requires you to purchase and install separate amp modules, adding cost and complexity.
