Some time ago, I sold my Crane Song Avocet (which was awesome). I was doing less and less music work and more and more electronics, so it was time to simplify. I built a very simple completely passive monitor controller with just the bare minimum features. It was just for me, so it was not pretty but functional. It has a stepped attenuator, polarity, L& R mutes and Mono.

This baby came in for a little inspection this week. The owner was worried that it was a ticking time bomb, as the start sequence would randomly take longer some days and not others. He mentioned, when cold, the unit could take 7-to 15 relay clicks to start. When warm and operating normally he would hear 3-5 relay clicks.

Today I recieved my MoCo, a monitor controller from the German manufacturer Esi. It is passive and can handle two stereo sources and two pairs of monitors.

It sounds very neutral, and is extremely quiet. It also has L/R swap functionality, mute and mono. Two things to consider: it has no status lights whatsoever and the housing is made of sturdy plastic.
