Mattoverse Echo Amp
type: Product
description: This is from my personal collection, not sure on the # but less than 15-20 of these were made I believe. The Echo Amp is a small standalone audio amplifier with a built-in speaker that consists of a preamp into a simple echo circuit into an op-amp gain circuit with the output fed into a small Class D power amp. Overall it is a bit noisier than I was aiming for and the wood enclosure versions can vibrate too much at certain frequencies.

Current draw is variable depending on the volume output setting and using a larger external speaker will draw more current than the small internal speaker, up to more than 600mA, recommend using a DC Power supply that can provide up to 1AMP of current, especially when using with an external speaker. 9V Battery Power: The unit can be powered with a standard 9V volt battery (included) which can be installed/replaced using the battery door on …
