Big, clear headroom Connecting a pedalboard output to a DI is completely different from plugging a bass or guitar directly into a DI. Pedalboards output a much louder signal, often overwhelming the input of a typical direct box. The PCH's 9VDC power supply is boosted to 24V internally, providing ample headroom to clearly handle even the most powerful inputs, ensuring your best sound every time. Compatible with any instrument No matter what instrument you play or genre of music, if you need an unbalanced output to connect directly to a PA, recording interface, or flat-response speaker system, the PCH is the ultimate choice for a perfectly clear and clean stereo direct interface.It's also the only interface that lets you monitor through the built-in headphone amplifier.
