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.

- Weight: 0.6 (Kg)
- Impedance: 50KΩ
- Input: RCA / XLR (selection switch)
- Output: RCA / XLR (selection switch)

Well made solid little unit, does exactly what it's supposed to do while audibly invisible.

Since I play music from my laptop to DAC, when I went from an integrated stereo to dual ZA3s (mono mode) I had to use my laptop's Windows sys tray for volume control - that got old fast. So I bought this passive preamp and it does the job with no fuss.The volume knob is weighty and smooth when adjusting and the device, as a whole, looks and feels much more premium than its price indicates. My intention was to use it temporarily while I saved for a more expensive preamp but I really like this little thing. It's added a little something in a good way to the sound that I can't quite put my finger on but whatever it is I like it. So, for now, it's apart of my base setup that I have no intentions of replacing it in the near future.

Bought this to put between by pre-amp and speaker amps as limiter. needed something completely passive since all the gain was done through sources (Schiit Bifrost) through EQ (Schiit Lokius) to Preamp/HPamp (Schiit Jotunheim) to speaker amps. I didn't want to cut the gain out of the DAC to limit any drops in bitdepth, and the Jotunheim adds gain, so no need to cut before re-adding again. Putting this after the preamp gave me plenty of headroom on the volume control of the Jotunheim without putting any color on the sound. Windows is also unreliable with the volume settings and there isn't an elegant way in the settings to really level control effectively.Perfect example of an audiophile-grade device, meaning no compromises, that does not have to cost a ton of money.

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.

No complaints for the price, I have a sensitive amp, no need for boost. There maybe better solutions out there in chi-fi, but at 3 times the price… be careful if trying to pull off the xlr’s, you have to jiggle them, you’ll see

Does what it says. Passive design doesn't affect sound quality. Knob has smooth feel to it. There's no static when I turn the knob, but at lowest levels the stereo balance is uneven (between 7 o'clock to 8 o'clock positions).Can be used as a mechanical switchbox between balanced -> unbalanced or unbalanced -> balanced components. User selectable input (XLR or RCA). User selectable output (XLR or RCA). This was really nice when I didn't have the appropriate cables handy.And as other reviews mention, the XLR input locks are ... permanent. I cannot get the input XLR cables out again. It appears that the locks are mounted too close to the chassis; there's not enough space to fully release the cable latch. This isn't a big deal for me, but it is undoubtedly important to consider for some.I'm happy.

I wanted to run my digital audio sources through a Cambridge DAC to my power amplifier but needed a volume attenuator between the DAC and the amp (ADCOM GFA-535). This small device worked perfectly to give me control of the volume. The pot works very smoothly and provides an excellent range of control. The only negative comment I have is in regard to the button toggles for selecting RCA or XLR input/output. They work fine but are very small and somewhat difficult to push.Overall, a well made and very useful device at a reasonable price that doesn't appear to add coloration to the audio signal. I would have paid more for a version with remote control of the volume though.

Don't bother buying this. It takes away so. Much sound out of ur amp and makes it sound horrible. Buy a topping dx3 pro or a D50 and be happy. I can't give it a zero star for sound.

I was really impressed by this monitor control and it provided me with exactly what I needed. I have a R/W CD player that doesn't have a output volume control and this solved the problem. I needed the RCA IN/OUT connectors. When connected it did not effect the OUTPUT volume at all. There was no noise, so it's clean on the output side. I have full control over a wide range of output now. It also has Balanced XLR IN&OUT. So it could be used for volume control of a Microphone or Monitors with XLR cable connections. It's small and can fit in a small area of your set-up. This Pre-Amp comes with four soft small rubber feet that attach with pre-applied adhesive. You just peel them off a paper and attach them to the bottom of the box. These keep it in place securely when you adjust the volume. I'd recommend this product and I would purchase another one if needed.

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.

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!
