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.
You’ll know.
PCH
has a powerful 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.
Connecting
the output of your pedalboard to a DI is a very different thing than
simply plugging your bass or guitar straight into one. Pedalboards can
generate very loud output signals, enough to swamp the input of
ordinary direct boxes. PCH is different, partially because it runs on
9VDC, and it has enough headroom to handle powerful incoming audio
while remaining pristine, ensuring you always sound your best.
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.
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
- 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
- Powered by a custom single-channel internal Ojai power supply
- Internal supply’s custom transformer provides galvanic isolation
- Extremely flat frequency response
- Extremely low total harmonic distortion
Construction
- Thick 3mm extruded aluminum external shell with 5mm ribs for bulletproof protection
- Shell awning design protects headphone volume pot while allowing easy access to jacks
- High quality long life jacks and switches
