The Crown I-Tech 12000HD is a two-channel 4500W-per-side touring amplifier with onboard BSS Omnidrive HD DSP — crossover, alignment, EQ, and limiting in the amp itself, all controllable from BSS Audio Architect. Pairs naturally with BSS Soundweb London system processors and a JBL VTX or VRX line array system, since all three live in the Harman ecosystem and share control software.

Product overview
Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.
The payoff
Power Amplifier decisions, organized around the whole rig.
The Crown I-Tech 12000HD sits at the top end of what a two-channel touring amplifier can be: 4500 watts per side with onboard BSS Omnidrive HD DSPDigital Signal Processing — the number-crunching that does EQ, compression, and effects inside a box. More DSP means more processing at once. handling crossoverSplits audio into frequency bands so each speaker only gets what it can handle — lows to the subs, highs to the horns., alignment delay, EQ, and limiting all inside the amp itself. That last part is the real story. If you are running a JBL VTX or VRX system and already working in BSS Audio Architect, this amp is essentially a node in your network rather than just a power source — tuning, protection curves, and system alignment live in the box and travel with it.

How it works in the path
The power numbers demand respect at the circuit level. Idle draw sits around 600 watts, but peak demand can reach 4500 watts, so this is not a one-per-circuit amplifier.

Where it earns its place in the rack
This amp earns its place in a serious touring or high-production install rig where you are already committed to the Harman ecosystem and need amplification that integrates natively with your system control software.

More DSP means more processing at once. is cost you won't use, and there are lighter, cheaper options. If you are flying line arrays, driving subwoofer arrays with precise alignment requirements, or managing a complex multiamp rig remotely, the I-Tech 12000HD removes an entire processing layer from the chain and puts it somewhere it will not get bumped off a console.

Use the AES input when your drive system supports it; keeping the signal digital all the way to the amp eliminates one analog conversion stage and any ground noise that comes with long analog cable runs.

DCi 4|600NThe Crown DCi 4|600N is the touring + install workhorse from the DCi line — four channels of 600W @ 4Ω, onboard DSP for crossover and limiting, and BLU link networking so the amp room talks to FOH over a single Cat6 instead of analog runs. Drives top boxes on monitor wedges and small/mid PA tops; pairs with a system processor like a Lake LM or BSS BLU host for full loudspeaker management. Lives in countless venue install rigs and touring fly racks.View gear →
DCi 8|600NThe Crown DCi 8|600N doubles the channel density of the DCi 4|600N — 8 × 600W @ 4Ω in the same 2U footprint. Drives monitor wedge arrays, distributed PA zones, or full-range systems where you want each driver on its own amp channel for precise alignment. BLU link networking talks to a BSS Soundweb host upstream so EQ + crossover + limiting comes from there. Ubiquitous on install + house-of-worship + small-to-mid touring.View gear →
XLi 3500The Crown XLi 3500 is the no-nonsense two-channel power amp that has been the entry point to "real touring power" for two decades. 1350W per channel @ 4Ω, no fancy DSP, no networking — just clean analog amplification with bridge-mono switchable for sub duty. Lives in regional touring rigs, schools, churches, practice rooms, and house systems where simplicity and bulletproof reliability beat features.View gear →
