Key Features

Passive Volume Control
Balanced 1/4" TRS Inputs
Unbalanced RCA and 3.5mm Inputs
Balanced XLR and 1/4" TRS Outputs

The ESI MoCo Passive Monitor Controller not only attenuates volume, but provides input and output switching to different monitor sets. Two sets of inputs can be sent to either of two sets of outputs (no balanced to unbalanced conversion). This way, your audio interface's balanced output can be sent to one of two sets of monitors, or select a secondary audio source to be output via either of those monitors. The front panel contains the large central knob, which drives a high-quality volume potentiometer, input and output selection buttons, plus an L/R switch and mono mixdown buttons.

Problem with Left Output Channel

By Pete

Rated 2 out of 5

Date: 2024-04-04

I liked the quietness, no distortion. I liked the design but I had to put a bigger marker (white adhesive) on the control knob to see where the volume indicator was -- it's a tiny red line which is very hard to see. But I had the same problem as other reviewers -- the left output channel failed even while the unit was kept stable in ideal conditions. See review by Stefan for the same report.

Love it and B&H Photo!

I've had this in my shopping cart for weeks and finally decided to buy it. I live in Canada and you can't get these here. I didn't want the Mackie Big Knob products because of the not so steller reviews concerning noise. I needed a controller to switch back and forth between my Eris monitors and my DT 770 Pro 250 ohms powered by a Monoprice headphone amp. It is flawless and very transparent no noise or added color from what I can tell. The knob is smooth and box doesn't feel cheap at all. I was a little hesistant to order out of country, but I chose the option that prepays all the duties and taxes and I got it via ups in about 4 days. Very fast! Highly recommend.. Just make sure you pre- plan to know what type of cables you might need depending on your setup.

I think this would be very useful for me, but would'nt expect any "magic". It probably has the characteristic of most level controllers that use potentiometers: at low volumes, balance shifts one way or the other (due to less than 100.000% accuracy in having identical pots). Also, pots probably get dirty (noisy) after a while. Do folks experience these issues with this device? Thank you. DG

Asked by: David

The ESI MoCo Passive Monitor Controller works just as described and does not add noise to the system. The potentiometer and switches should not get dirty if the environment where it is used is fairly clean and not dusty. If you are concerned about dirt getting inside, simply cover the unit with a cloth or a vinyl or plastic cover like you would use to cover a keyboard when it is not being used. We have had no complaints at all regarding the MoCo, only positive customer reviews which you can read for yourself. Why expect that there will be problems when customers have only reported having a good experience using this device?

What is the best way to connect this with my iMac as the input?

Asked by: Hailey

In order to get audio from an iMac to this speaker controller, you would either come out of the 3.5mm headphone/speaker output of the computer, or use it in conjunction with an audio interface, which would be connected to the computer via Thunberbolt or USB..

Can you plug good studio headphones into the stereo output on the back and toggle between the headphones and Nearfield monitors?

Asked by: Landon

Yes, you can connect studio headphones and nearfield monitors and toggle between them. Depending on the headphones, you may want to use them with a headphone amplifier to provide more gain.
