## Description

Product Description Passive Monitor Controller with 2 stereo I/O MoCo is a fully passive monitor controller that helps you to provide perfect control over the playback volume of your studio monitors. "Fully passive" means that there are no active components involved, that could in any way alter the audio signal - keeping the maximum sound quality level for your studio monitors. MoCo provides two separate stereo inputs (one with balanced 1/4" TRS connectors, one with both unbalanced RCA and unbalanced 1/8" TRS connectors) and two separate stereo outputs (one with balanced XLR connectors, one with balanced / unbalanced 1/4" TRS plus unbalanced 1/8" TRS connectors). MoCo does not change your signals from unbalanced to balanced: what goes in, goes out! Via one switch you can select the input signal and with separate buttons, each output can be enabled. Also there is a switch that changes the monitor signal to mono and you can mute the playback audio signal quickly at the touch of a button. A quick swap of the left and right audio signal channels is also possible. And of course, the stylish big knob in the center of MoCo controls the actual playback volume.

Review: Great bit of kit that does what it says well. - It's curious that something like this exists to fill a gap in the market, it does few things, I was baffled to find out I needed it and that there wasn't a cheaper and simpler solution when all I wanted was just something to be able to switch off speakers whilst still retaining headphone sound from the audio interface box. This is what you need. Yeah it's 50 quid but it really is the sort of thing you wondered how you managed without and it's a high quality studio level bit of equipment that has surpassed all my expectations, and I have found uses for it in different ways, connect up a 3.5mm aux input and press a button for that, the volume knob is 'grab and go' and super smooth and this thing adds absolutely no noise. I added XLR cables from the Moco to the monitor speakers which got rid of low noise going direct from the audio interface, which was happening using the phono connectors which now go to the Moco, that was a pleasant surprise. So yeah, for the price this is an essential bit of studio kit if you need it. Well done ESI on a fine product.
Review: No hum or buzz noise at full volume.. (as with Mackie Big Knob passive) hooray! - I originally bought the Mackie Big knob - whilst I liked the look and feel and functionality in terms of buttons, the dim button was a good thought, at full volume I was getting a hum.. I have decent cables, short run, so was confident it wasn't a cable issue. Had it replaced with another Mackie Big Knob (passive) and had the same issue, so sent that one back too.. just received this Moco and it's fabulous.. absolute zero noise/hum at full volume, so full marks for quality internal circuitry ESI.. did mean I had to buy some XLR leads as you need both 1/4 inch jack and XLR to use the dual monitor A/B function.. but ultimately, I'm a happy customer.. looks and feels great.. Also, I found the Mackie Big Knob (passive) couldn't quite reach the same level of output as going straight from audio interface to monitors.. whereas this Moco can!

### ⭐⭐⭐⭐⭐ Great bit of kit that does what it says well.
*by A***R on 8 November 2019*

### ⭐⭐⭐⭐⭐ No hum or buzz noise at full volume.. (as with Mackie Big Knob passive) hooray!
*by T***R on 29 April 2019*

I have decent cables, short run, so was confident it wasn't a cable issue.

### ⭐⭐⭐⭐ Well built, easy to use but does suffer some channel-bleed
*by J***) on 30 May 2023*

I needed a way to provide two inputs to my powered speakers to switch between my DJ controller and an aux input (in this case a Sonos Port) without needing my DJ controller being plugged in / turned on. Setting up the MoCo is child's play, just plug in the inputs and outputs and you're good to go - no power required. The unit feels well made with soft touch plastics on the large and fluid knob and buttons which feel good quality (if a little plastic-y). There are rubber feet on the bottom which do a good job of stopping the device moving around, even when connected to the thick XLR cables. The only criticism of the device I have is that there is some channel-bleed between the two channels. If I select channel A (my DJ controller) and there is line input on channel B, you can hear it bleed through ever so slightly but noticeable nonetheless. Overall I'm very happy with the purchase given the price and the channel bleed can be mitigated by stopping the input on the redundant channel.
