## Questions & Answers

**Q: Is the reason for this box to convert unbalanced rcas to a balanced xlr signal? it’s just for defeating possible unbalanced signal noise?**
A: I think most people purchase this box for volume control.  It has a high quality potentiometer for this purpose.  It will convert an RCA input to a balanced, XLR, output.  But it would probably be more cost effective, and space saving, to purchase RCA to XLR cables if that’s all you want to do.

**Q: Does this preamp output +4dBu or -10dbV?**
A: Hello. This is a fully passive preamp with no amplification function.

**Q: Is the case (including front panel) made of metal?**
A: Yes, all metal. It is a ver solid unit.

**Q: Can i use this between an amp (Topping MX3) and powered speakers to protect the speakers amp?**
A: No.  It would make more sense to use the headphone output and find a splitter to connect it to your powered speakers.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Wonderful and simple
*by J***N on August 27, 2025*

I use this control knob for my speakers attached to my record player. Without it, I have to adjust the output on the back of each speaker (annoying). Now I can use a single volume controller to conveniently and evenly adjust the volume of both speakers together.This device does not require a power source.The device is housed in a metal body and feels solid and durable.The volume output controll is well spaced and increases or decreases evenly with the turn of the knob

### ⭐⭐⭐⭐⭐ Better than hoped for my needs
*by J***L on June 16, 2022*

I bought the Xduoo MT-604 hybrid amp, which has separate volume controls for right and left ears (annoying). Furthermore, the volume ramp up on this amp was SO FAST for each knob. THEN I hooked up my new Hifiman EF400 as a DAC, which seemed to overdrive and distort the inputs on the MT-604. My Focal Clear and Spirit Torino Radiante sounded too sharp/abrasive.This wee volume knob solved ALL of these problems. I can raise the volume on the hybrid amp way higher (probably getting more out of the amp), and I can control the volume with ONE knob. In addition, the output from the Hifiman DAC no longer runs hot into the amp, so the distortion is gone.IN ADDITION (big suprise), my formerly sharp Focal Clears and Radiante both sound well-tuned and easy to listen to. They sound fantastic now on the same hybrid amp.So, for me, I'm overjoyed by this product.That said, I'm not sure whether an impedance "issue" with this knob may be changing the sound signature of the output in ways that may be problematic for other users, or whether simply tempering the hot DAC output and cranking the amp "balanced" the headphone sound. So there may be a problem lurking for others with different gear, but for my situation I am extremely pleased.Everything sounds and feels excellent. No issues in my very short time with it. The price and value are fantastic relative to most alternatives. I very highly recommend at least trying this product if you have a similar need.

### ⭐⭐⭐⭐⭐ Does exactly what it was designed to do... and does it well.
*by W***W on January 17, 2019*

Remember this is just a volume knob that can switch from RCA to XLR on inputs and outputs. That is it. All and everythign it does... I'm using it to control volume and switch between the Pre-amp in my Cambridge DAC (XLR in) and the Pre-amp on my turntable (RCA in) before going to my Crown XLS 1502 Amp (XLR out). There is no noticeable noise or anything added at high volume, to my ears anyways, which can't hear most mid-range anymore but are extremely tuned to very quiet high and low frequency according to my hearing tests at work. Volume knob is super smooth, but sturdy. Switching between XLR an RCA is tactile and firm, and should last as long as you don't sit and play with it. The box is small, but dense. The quality should honestly be good enough for most "audiophiles" even.
