EA iAMP Micro 300

The US made, EA iAMP Micro 300 is a tiny but powerful amp. At just a touch over three pounds, this Class D amp will deliver 300 watts into a four ohm load. It offers two channels with independent three-band equalization, and when using one input only you can switch from one channel to another using a footswitch!

EA has wisely addressed the sometimes questionable power levels we encounter on the stage from hell (I've been there, I'll bet you have, too). Their 4” by 4” Switching Power Supply features true Power Factor Correction from 100-240 volts and from 50-60 Hz, so if you're caught in a low voltage situation at the end of a pier in NJ (happens to me!), the Micro 300 can still deliver a cool 300 watts (@ 4ohms), even down to 100 volts.

The power amp of the Micro 300 is based on the proven Class D power amp technology of the iAMP 200 (Wizzy Combo). This 3” by 4” power amp’s highly efficient design means neither cooling fan or external heat sinks are necessary.

All this and more in a package weighing around 3lbs (1.36kgs) and the size of a 1/2 sheet of paper!


  • Inputs: Two separate and distinct channels with individual controls.
  • Trim controls to adjust the overall level of channel one, channel two,and the
    DI output
  • Intelligent Input Switching with optional footswitch; you can use a single or double momentary contact footswitch (we are sourcing a double switch that we'll make available for your convenience)

    With one instrument plugged in, the switch toggles the instrument between channel one and channel two, so there can be different settings

    With two instruments plugged in, the switch moves from >Channel one > Channel two > Both

  • A single footswitch controls the Intelligent Input Switching; when a double (¼ TRS plug) switch is used, the second button controls the mute function
  • Controls: Channel switch, Input gain, 3-Band EQ, Master Volume, Mute switch, Effects loop blend
  • EQ: Low, Mid, and High for each channel
