Ampera - Quad VCA

You can never have too many voltage controlled amplifiers VCAs! (voltage controlled amplifiers). Ampera offers 4x VCAs in a tiny 6HP footprint with manual potentiometer control mixed with CV control.  

Amplification ranges between 0.1x-2x, so you can make your 5V signals 10V with an offset voltage. Chain 2 channels together, and you have boost. 
Ampera has bi-polar LEDs that display red or blue depending on the polarity of the signal. At audio rates, the LEDs show purple. 

An excellent solution for those with small systems, or those just looking to free-up some space in their Eurorack cases.
