EA Micro 300 Musical Instrument Amplifier

Manufactured by: Euphonic Audio

The US made, EA iAMP Micro 300 is a tiny but powerful amp. At around three pounds, this Class D amp will deliver 300 watts into a four or two 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! (not included, see below for some switch suggestions)

EA has wisely addressed the sometimes questionable power levels we encounter on the stage from hell (I've been there, and 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. Please note: The current model is for US and other approx 110-120 volt power countries only. EA found that some areas of the world with "240 volt" power actually exceeded 260 volt peaks, which the Micro could not handle. The next group of Micro 300 will have a revised power supply that will be able to handle worldwide voltages, probably during the fourth quarter of 2008.

The Wizzy 10 can make an excellent companion speaker for a powerful yet compact rig. In spite of being so light and compact it can deliver quite a punch. At the right is a photo of true Bass Bliss, with Bob at a September 2008 outdoor party gig playing a Micro 300/Wizzy 10 rig. Carrying it in and out of a gig was bliss, too.

The power amp of the Micro 300 is based on the proven Class D power amp technology of the iAMP 200 (Wizzy Combo). This 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 3 pounds and the size of a 1/2 sheet of paper!

1 foot DI Breakout Cable (TRS 1/4 to XLR)

This short cable works great as a breakout cable for the EA Micro amplifier; it is an adapter for the TRS (Tip/Ring/Sleeve) jack on the amp to a standard "mic" cable (XLR) for connection to a house sound system...
