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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePCH X2 is really two PCH X1s in the same enclosure for nearly identical audio performance\u003c\/li\u003e\n  \u003cli\u003eBoth feature a custom audio transformer per channel\u003c\/li\u003e\n  \u003cli\u003eBoth run on phantom power (each channel requires power)\u003c\/li\u003e\n  \u003cli\u003eDefeatable Sum merges the Left and Right inputs and sends them to the Left outputs (X2 only)\u003c\/li\u003e\n  \u003cli\u003eGround Lift Switch per channel\u003c\/li\u003e\n  \u003cli\u003eThree-position high pass filter per channel\u003c\/li\u003e\n  \u003cli\u003eExtremely flat frequency response\u003c\/li\u003e\n  \u003cli\u003eLow total harmonic distortion (THD)\u003c\/li\u003e\n  \u003cli\u003eThick 3mm extruded aluminum shell with 5mm ribs for bulletproof protection\u003c\/li\u003e\n  \u003cli\u003eShell awning design protects switches while allowing easy access\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003eTheir phantom-powered and transformer-isolated PCH X1 and X2 active direct interfaces are \ndifferent. Designed to be pristine-sounding before any other feature, these are units that you \ncan 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 \ndogs can hear (80KHz) within a half of a db, as well as remaining clean and quiet throughout \nthat range.\u003c\/p\u003e \n\n\u003ch4\u003eFeature Rich\u003c\/h4\u003e\n\n\u003cp\u003eAlong with pristine audio, PCH X1 and X2 were designed with a host of real-world features that \nmake them ideal as direct interfaces and line isolators. Housed in a bulletproof 3mm extruded \naluminum chassis for protection, it doesn’t matter if you’re using them on a loud stage or in a \nquiet world-class recording studio, X1 and X2 balance your audio perfectly - and they’re small \nenough to fit just about anywhere.\u003c\/p\u003e \n\n\u003cp\u003eX2 is really two X1’s in the same enclosure, so their audio performance and behavior are largely \nidentical. Each channel’s audio passes through a custom transformer, eliminating most ground \nloops and offering true galvanic isolation. Each unit also features a ground lift switch per \nchannel to combat hum, as well as a three position high pass filter that allows you to roll off\nlow frequencies at two different points: 80Hz for taming rumble, and 240Hz for more \ndramatically carving out space in the mix for low frequencies on other instruments. \u003c\/p\u003e \n\n\u003cp\u003eX2 features a phase reversal switch for reversing the polarity of the left XLR output, as well as a \nSum switch that sums the inputs together and passes them to the left outputs (the right XLR \noutput mutes to let you know Sum is engaged), allowing you to interface with both mono and \nstereo scenarios on the go without having to rewire anything. \u003c\/p\u003e \n\n\u003cp\u003eBoth the X1 and X2 feature a non-buffered Thru output in addition to the balanced XLR out, \nallowing you to feed the input signal to an additional device like an onstage monitor or \ninstrument amplifier separately from the balanced output.\u003c\/p\u003e \n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInput Impedance: 2 MΩ (For PCH X2, when SUM enabled: 4 kΩ)\u003c\/li\u003e\n  \u003cli\u003eMax Input Level: +20.5 dBu\u003c\/li\u003e\n  \u003cli\u003eXLR Out Output Impedance: 100 Ω\u003c\/li\u003e\n  \u003cli\u003eGain Relative to Inputs: -20 dB\u003c\/li\u003e\n  \u003cli\u003eMaximum Output Level: +0.5 dBu\u003c\/li\u003e\n  \u003cli\u003eNoise Floor: -123 dBu (10–22 kHz, no A-Weight)\u003c\/li\u003e\n  \u003cli\u003eFrequency Response: ±0.25 dB, 20 Hz – 30 kHz (13.6 kΩ load, HPF off)\u003c\/li\u003e\n  \u003cli\u003eFrequency Response: ±0.5 dB, 10 Hz – 80 kHz (13.6 kΩ load, HPF off)\u003c\/li\u003e\n  \u003cli\u003eFrequency Response: ±0.5 dB, 20 Hz – 20 kHz (600 Ω load, HPF off)\u003c\/li\u003e\n  \u003cli\u003eTHD+N @ 1 kHz: 0.0007% (-10 dBu out)\u003c\/li\u003e\n  \u003cli\u003eTHD+N @ 100 Hz: 0.0035% (-10 dBu out)\u003c\/li\u003e\n  \u003cli\u003eTHD+N @ 50 Hz: 0.0125% (-10 dBu out)\u003c\/li\u003e\n  \u003cli\u003eThru Gain Relative to Inputs: +0 dB (For PCH X2, when SUM enabled: -6 dB)\u003c\/li\u003e\n  \u003cli\u003eThru Output Impedance: 0 Ω (For PCH X2, when SUM enabled: 1 kΩ)\u003c\/li\u003e\n  \u003cli\u003ePower Requirements: 5 mA @ +48VDC (per channel)\u003c\/li\u003e\n  \u003cli\u003eDimensions X1: L – 3.66″ (93 mm), W – 1.97″ (50 mm), H – 1.54″ (39 mm)\u003c\/li\u003e\n  \u003cli\u003eDimensions X2: L – 3.66″ (93 mm), W – 4.20″ (107 mm), H – 1.54″ (39 mm)\u003c\/li\u003e\n  \u003cli\u003eIn: 1\/4\" unbalanced TS high-impedance input(s) for guitar, bass, keyboard, amp + cab simulation pedal, drum machine, modeler, or other audio sources\u003c\/li\u003e\n  \u003cli\u003eThru: 1\/4\" unbalanced Left and Right TS output(s) passing unbuffered input source(s) to amplifiers, effects, or other devices\u003c\/li\u003e\n  \u003cli\u003eXLR Out: Balanced, low-impedance output(s) for connection to mixing consoles or other low-impedance gear\u003c\/li\u003e\n  \u003cli\u003eStereo Sum: Merges stereo inputs to Left Thru and Left XLR output (Right output muted when engaged)\u003c\/li\u003e\n  \u003cli\u003eGround Lift: Lifts ground to eliminate hum on XLR Out(s)\u003c\/li\u003e\n  \u003cli\u003eVariable HPF: 6 dB\/octave filtering below 80 Hz or 240 Hz\u003c\/li\u003e\n  \u003cli\u003ePhase Reverse: Reverses polarity of the Left channel XLR output\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Strymon\u003cbr\u003eModel: Z120-PCHX1\u003cbr\u003eSKU: I919713-N-3-WHXX\u003cbr\u003eUPC: 852571008677\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.
