Crown Updates Macro-Tech i Series Amps

Crown announced the latest update to its Macro-Tech i series of amplifiers, featuring increased power and new dual port capability.
Comprised of three models, the MA-5000i, MA-9000i, and MA-12000i, the Macro-Tech i series features Class-I circuitry, designed to deliver greater power while reducing the amplifier’s weight by more than half.

The new Macro-Tech i series also features dual-port capability. An additional network port now allows a user to daisy chain the network control down the rack of amplifiers instead of having to run a separate cable from a switch to each individual amplifier.

All Macro-Tech i amplifiers are also equipped with comprehensive status, fault, and load monitoring via standard Harman HiQnet System Architect software, Crown says. A universal power-factor corrected power supply is designed to ensure that the amps can be anywhere in the world.

Power output ratings on the newly updated Macro-Tech i series are as follows:
  • MA-5000i — 3000W per channel at 2 ohms (with 2565W 20mS burst), 2500W per channel at 4 ohms, 1250W per channel at 8 ohms, 4000W at 4 ohms bridged, and 5000W at 8 ohms bridged
  • MA-9000i — 4700W per channel at 2 ohms (with 4570W 20mS burst), 3500W per channel at 4 ohms, 1500W per channel at 8 ohms, 5600W at 4 ohms bridged, and 7000W at 8 ohms bridged
  • MA-12000i — 6000W per channel at 2 ohms (with 5900W 20mS burst), 4500W per channel at 4 ohms, 2100W per channel at 8 ohms, 7500W at 4 ohms bridged, and 9000W at 8 ohms bridged

    i have the 9000i amp it has one network port and has less power than 9000i amp listed on the up graded.. --i want to buy another 9000i but want the same power as the power listed when i bought it.. Like 2 ohms 2500 watts--i will need the single network port correct --
