Review: Does exactly what it says on the box. - I have two different studio monitor sets: an old pair of iLoud Micro Monitors and a new pair of Kali LP-6's. Having both of them hooked up to this thing is a god-send versus having to open the routing software over and over again to switch between them during a recording or mixing session. It's also quite heavy and very sturdy, which is a good thing when you got several cables hanging out from behind the unit which could overcome units built more lightly if they are all hanging down from back back. The Mono button is great for checking mixes in mono and it also makes listening to old mono recorded songs (with the instruments in the left and right and not "stereo" from the get go) a breeze as well. The Dim button is great even at home as I can set the knob to a specific spot and then just use the button to lower the volume in an instant. As long as you have all the correct cables (I make sure to use TRS cables for the connection from my interface, you can use TS cables but YMMV) and read the manual to make sure everything is hooked up, it's a absolutely worthy buy for the home studio. I have cranked it up as well and I cannot perceive any additional line noise from either speaker, thanks to it being a well designed and fully passive circuit path.
Review: Very well put together tool. - Loving it so far. Very nice and sturdy. Works well for what it does. My only minor gripe is that the volume knob while big, has very little resistance when moving. By very little I mean almost none. It would be nice to have a little resistance for tactile feedback while moving, but as I said before, it's a small gripe. Using for multiple inputs and multiple outs in a recording studio. The dim button works well for alternating between a louder (checking bass and drums) setting and a quieter (balance and tone) listening environment. The mute button does what it says. The mono button is a fantastic tool for checking your mix for phasing issues and for (believe it or not) checking panning and how well everything sits in the mix. No coloration that would affect your mix to the sound as far as I can tell and test. Easy to set up in the studio and will hopefully last a long time.

## Questions & Answers

**Q: Can you plug in a sub-woofer?**
A: Only if your sub feeds your monitors. If you don't know the answer to that question, you should probably start there. This device just provides 2 source inputs, and 2 stereo outputs.

**Q: I want to use this to control if sound comes through my headphones or studio monitors. Is the phones out affected by the mute or monitor toggles?**
A: It has 2 headphone outputs, each with their own control, and a knob to choose between cue an input.  It is not affected by monitor toggles or mute; those just turn the respective monitor speaker on and off.  I run my mains on A and my subs on B for independent control.  Each monitor also has its own trim level to manage balance.

This thing behaves like any line mixer should.

**Q: is there a way to turn your voice on and off while recording?**
A: yes.

**Q: What cables do i need? i do not know how to set up. i have 2 krk studio monitors and scarlet solo interface. please help**
A: You need 2x RCA to 1/4" cables to connect your Scarlett to the Big Knob, and 2x 1/4" to 1/4" to connect the Big Knob to your monitors. Since the Scarlett is unbalanced out, there's no reason to use TRS (balanced) cables for your monitor run.

### ⭐⭐⭐⭐⭐ Modifiable to use common subwoofer
*by P***J on February 1, 2023*

What I wanted was a fully passive monitor control that switched two stereo inputs into two stereo outputs, AND offers a common subwoofer output regardless of the monitors chosen. I noticed this had some space in the rear panel once the 1/8” jack would be removed, so I got a slightly used one from Amazon warehouse and drilled and soldered. Pic attached. Works fine, although this is a bit of an advanced mod. I used the same 150ohm resistors on the sub outs used on the monitor outs, on both pins 2 and 3. Speaking of which, this unit runs only impedance balanced (it's passive, just using resistors, rather than active balancing or transformer balancing). Sure it accepts balanced connections, but pin 3 just runs 150ohms to ground both in and out, which will net fairly modest noise removal from the cable run. Otherwise they’d need a very fancy potentiometer double dual gang with very strict tolerances. Unbal to monitors with short cable runs not such a problem, but it is somewhat of a volume loss, beyond the loss this unit already has by design. Monitors are typically too loud anyway when driven at line level. There are also a pair of 10uF electrolytics…polarized commodity ones…between input and output. I shunted those off but most people should probably leave them, they don’t hurt the sound much. And 100pf ceramic caps avoiding RF interference coming down the line, perhaps bleeding off a touch of high end in the process. I left those. The next day (not shown in the photo) I also added an On-Off-On toggle under the logo on the back, that offers follow, mute, and solo for the subwoofer, handy for Room EQ Wizard or just hearing what your subs vs monitors are doing. The solo works in conjunction with the main mute button as a fast A/B. Anyway this did solve my problem after modding and the unit is heavy and the knob feels smooth and heavy like a hifi receiver. I improved the signal path a touch and the functionality a ton. I just wanted to show this mod is possible and is good enough to avoid spending more if you can hack it and that’s all you need.
