PCH is an advanced 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.

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.

Features:

Runs on 9VDC — internally converted to 24V to be virtually unclippable
Onboard headphone amplifier powerful enough to drive high impedance headphones cleanly
Switchable Mic/Line level operation for the XLR outputs
Defeatable ground lift for the XLR outputs
Defeatable Sum for the Thru outputs
