A Real Transformation
Putting a typical direct box on a high quality analyzer can reveal all manner of hidden issues - units sold as premium often exhibit audio behavior that is anything but, especially in the low frequency region or in measured total harmonic distortion. If you disregard all of the technical mumbo jumbo it just boils down to this: the audio running through your direct box is often being treated poorly.

Our phantom-powered and transformer-isolated PCH X1 and X2 active direct interfaces are different. Designed to be pristine-sounding before any other feature, these are units that you can trust implicitly to handle your audio, no matter what kind of signal it is. Other direct boxes can distort low frequencies to the point where a low B on a bass guitar barely resembles the input, but the PCH X1 and X2 remain flat from far lower than that (10Hz) to well above what dogs can hear (80KHz) within a half of a db, as well as remaining clean and quiet throughout that range.

Feature Rich
Along with pristine audio, PCH X1 and X2 were designed with a host of real-world features that make them ideal as direct interfaces and line isolators. Housed in a bulletproof 3mm extruded aluminum chassis for protection, it doesn’t matter if you’re using them on a loud stage or in a quiet world-class recording studio, X1 and X2 balance your audio perfectly and they’re small enough to fit just about anywhere.

X2 is really two X1’s in the same enclosure, so their audio performance and behavior are largely identical. Each channel’s audio passes through a custom transformer, eliminating most ground loops and offering true galvanic isolation. Each unit also features a ground lift switch per channel to combat hum, as well as a three position high pass filter that allows you to roll off low frequencies at two different points: 80Hz for taming rumble, and 240Hz for more dramatically carving out space in the mix for low frequencies on other instruments.

X2 features a phase reversal switch for reversing the polarity of the left XLR output, as well as a Sum switch that sums the inputs together and passes them to the left outputs (the right XLR output mutes to let you know Sum is engaged), allowing you to interface with both mono and stereo scenarios on the go without having to rewire anything.

Both the X1 and X2 feature a non-buffered Thru output in addition to the balanced XLR out, allowing you to feed the input signal to an additional device like an onstage monitor or instrument amplifier separately from the balanced output.

Controls and Routing (the + hashmarks) 

  • In -  1/4" unbalanced, TS, high-impedance input(s). Connect guitar, bass, keyboard, amp+cab simulation pedal, drum machine, modeler or any audio source needing to be balanced.
  • Thru - 1/4" unbalanced, Left and Right, TS output(s). Passes your unbuffered input source(s) to amplifiers, effects, or other devices.
  • XLR Out - Balanced, low impedance output(s). Connect to a mixing console or other low 
    impedance gear.
  • Stereo Sum - Engage SUM to merge the stereo inputs and feed them to both the Left Thru and 
  • LEFT XLR output (the Right output will be muted to let you know Sum is engaged).
  • Ground Lift - Engage to lift the ground if you experience hum on the XLR Out(s).
  • Variable HPF - Allows 6db/octave filtering of low frequencies below either 80Hz or 240Hz
  • Phase Reverse - reverses the polarity of the Left channel XLR output

Very Poor Built Quality
Color: Black, Size: 3-Panel
They use cheap tarp like cloth that you might find on a tent, so it is not suitable as a teleconferencing background without blur applied. The legs are flimsy and lack rubber feet, so it will scratch floors. The tubing is flimsy and very hard to move and adjust. This is only good if you are setting it up somewhere like a gym or a garage.

These are PERFECT for my Art Show coming up!
This is going to be PERFECT for my Art Show display. And also....EASY to put up and take down as well as store. I'm so grateful to have found them! They are super light weight. And sturdy for my application. And elegant and have clean lines for my display. I have ivy draped and also fairy lights which make it look classy yet simple! Love them!

Rustic Wall Shelves That Just Work
Size: 17inch, Color: Black
I bought these six floating shelves to add some storage and a cohesive look to a few walls around the house. The set has a rustic real wood vibe with an industrial edge, and the black finish keeps things feeling clean and understated. It turned out to be a practical way to create space without committing to a bulky cabinet, and I appreciated having multiple pieces to arrange in different rooms. Installation was straightforward. The package includes 12 brackets, wall anchors and screws, plus clear directions, so I could get them up without much hassle. It takes about eight minutes to mount each shelf, and the hardware feels solid. The shelves can hold around 20 pounds each, which is plenty for everyday items like books, a plant, an alarm clock, or framed photos. In use, the look is exactly what I wanted: sturdy, simple, and able to blend with existing decor across the bedroom, bathroom, kitchen, and living room. The real wood surface and the exposed metal brackets give a cohesive, rustic vibe that elevates plain walls and makes it easy to rotate items in and out. One small note is that the boards are 17 inches long and about an inch thick, so planning spacing and wall space matters a bit. The brackets being visible is part of the look, not a flaw, but it means accurate mounting is important. Overall I am very pleased with the set and it earns a solid five stars.

Great shelves
Size: 17inch, Color: Light Walnut, Size: 17inch, Color: Light Walnut
I love how these look in the nook in my bathroom. I needed 6 inch shelves and this was way easier than ripping 8 inch from the hardware store
