Passive Monitor Controller- Take 2

Some time ago, I sold my Cranesong 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.

Digi 003 Controller- Issues with power sequence- Too Many Relay Clicks

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.

I was able to experiences this extended start up the first time I turned it on, I counted 7 clicks, but it did start. I turned it off and back on, and it took three clicks to boot.

Monitor Controller by Esi - the MoCo.

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.

Monitor Controller Recomendation

I'd like to improve my monitoring setup, and one of the things I'd like to have is a Mid/SIDE listening feature, so I'd like to have a controller that allows me to check mid or side content right with a button push.

Right now, I'm DM d-box as monitor controller.
I love d-box. I think that for that money is a stunning device!
I've been doing some test with it to check the quality of its DA.

  1. On one case I use d-box's DA (receiving HEDD's AES output)
