Macro Tech MA 12000i Power Amplifier

The i-Series continues the Macro-Tech legacy of unparalleled sonic accuracy and detail, putting sound quality above all else. For over two decades, Crown International's Macro-Tech Series has been embraced by the professional sound reinforcement industry as the most reliable, best sounding analog power amplifier line that money can buy. Now, thanks to the advent of newer technologies, Crown has undergone a careful yet significant refresh of the range, which was globally re-launched at Musikmesse Prolight+Sound in Frankfurt as the Macro-Tech i Series. Comprised of three models--the MA-5000i, MA-9000i and MA12000i (being sold here)--the Macro-Tech i Series builds upon its predecessor by incorporating Crown's advanced, patented Class-I circuitry, which efficiently delivers significantly greater power while simultaneously reducing overall amplifier weight by more than half. The new lineup is also equipped with comprehensive status, fault, and load monitoring via standard Ethernet networking and Harman Pro's HiQnet? and System Architect software. Furthermore, a universal power-factor corrected power supply ensures that the new models can be used literally anywhere in the world, delivering full rated power regardless of where touring schedules may lead.

Front Panel Controls and Indicators * Bridge Mode Indicator: Amber LED illuminates when the amplifier is set to Bridge-Mono mode. * Ready Indicator: Red LED, one per channel. Bright red: Channel is ready to pass audio. Red: Onset of compression (thermal event or fan failure). Off:Thermal event has occurred. * Signal Indicators: One green LED per channel. Solid green: Input signal is above –40 dBu. Bright green: Channel’s output signal has reached the onset of audible clipping. * Power Indicator: Blue LED indicates amplifier has been turned on and AC power is available. The LED will flash when the AC line voltage is 10% above or below the nominal rated value. * Data Indicator: Yellow LED on front panel indicates network data activity.Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online * Power Switch: Push-on/push-off switch with built-in green AC mains present indicator. * Volume Control: Precision detented attenuator with 31 steps,press-and-hold mute function. * Volume Control LED Ring: A ring of green LEDs around each volume control show the position of the control. Entire ring flashes when channel is muted.Can be converted to be a level meter. Back Panel Controls, Indicators and Connectors * Power Cord Connector: Locking, detachable 20 amp IEC inlet. Voltage range is indicated above IEC inlet. * Reset Switch/Circuit Breaker: If the current draw of the amplifier exceeds safe limits, this breaker automatically disconnects the power supply from theAC mains.
