Strymon PCH Active Direct Audio Interface

Hear Everything!
PCH is an ultra-premium stereo active direct interface with a hidden superpower - an onboard
console-quality headphone amplifier. Now you can rest easy knowing that the sound of your
pedalboard won’t change even a little when passing through PCH, and the headphone amp
means you won’t have to ask anyone how you sound. You’ll know.

PCH has a recording console-quality headphone amplifier onboard, making it easy to monitor
or practice listening to the sound of your entire rig or pedalboard in full stereo, no matter the
pedal order or the components. No matter what instrument or genre of music you play, if you need to connect unbalanced
outputs to a PA, recording interface or flat response speaker system, PCH is the ultimate
choice for an absolutely transparent stereo direct interface - and it’s the only one that you can
listen to locally via the headphone amp.

TRANSPARENT BY DESIGN
PCH was designed from the ground up to be sonically transparent, virtually unclippable and
bulletproof - it’s the ultimate solution for your pedalboard, keyboard rig or synth setup.


Technology And Features
1. Two channel design - use in stereo or dual mono, whichever fits your setup
2. Runs on 9VDC - internally converted to 24V to be virtually unclippable
3. Onboard headphone amplifier powerful enough to drive high impedance headphones
4. Switchable Mic/Line level operation for the XLR outputs
5. Defeatable ground lift for the XLR outputs
6. Defeatable Sum for the Thru outputs
7. Internal supply uses custom transformer for galvanic isolation
8. Basically, PCH runs off of a modified internal mini Ojai power supply
9. Flat frequency response
10. Extremely low THD (Total Harmonic Distortion)

Construction
1. Thick 3mm extruded aluminum external shell with 5mm ribs for bulletproof protection
2. Shell awning design protects headphone volume pot while allowing easy access to jacks
3. High quality long life jacks and switches
