## Description

The Best Choice for Active Speakers More and more audiophiles find that the behavior of normal multimedia speakers cannot meet their demands, and then they choose professional active monitor speakers. However, this kind of speakers usually doesn't have a volume controller, which means a pre amplifier is needed. Active monitor speakers are mostly placed on the desk and used for near field listening. So they need to consider the area required for Hi Fi pre amplifiers (normally very big). What'more, different pre amplifiers may differ in their timbres and this is the most bothersome issue. As an audiophile brand, Nobsound decided to solve this problem and designed this product. Its small size won't take much place and its clean silver color suits for various usage scenarios. There is no amplifying circuit in the device and won't change the timbre, while the amplifier in the active speaker is enough to drive it. With this product, you can enjoy the most original timbre and quality of the speakers and won't be trapped in the selection of pre amplifiers. Specifications: Dimension: 148 x 48 x 80 (mm) Weight: 0.6 (Kg) Impedance: 50K Input: RCA / XLR (selection switch) Output: RCA / XLR (selection switch) Package: 1 pre amplifier

Review: Great price and perfect for my application. I wanted to switch between my subs and headphone amp from the XLR connectors on my DAC/preamp. This little unit does the trick perfectly. I can't hear any sonic degradation, even through my Hafler HA15 headphone amp and Grado GH4 headphones. It also gave me one level controller for my dual subs, which are in opposite corners of the room. Nicely built unit and well thought out.
Review: 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.

## 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.

I needed an all passive volume knob with XLR in and out, and this fits the bill perfectly. Doesn't seem to color the sound noticeably, and works just fine. I'm running a standalone USB DAC to a Marantz 5 channel Power amp. Since the power amp has no volume control, this fit the bill. This item is definitely a niche product for a very uncommon setup. Make sure this is what you need!
