Strymon PCH-1 DI Active Direct Interface

The PCH is an advanced stereo active direct interface designed for musicians who demand absolute transparency, pristine audio quality and complete confidence in their sound. With a powerful built in console grade headphone amplifier, PCH allows you to monitor your pedalboard or rig in full stereo at any time — ensuring you always know exactly how you sound before your signal reaches the PA, recording interface or speaker system.

Whether you play guitar, bass, keys or any instrument with unbalanced outputs, PCH provides a clean, reliable and ultra transparent stereo DI solution unlike anything else on the market.

The Only DI That Lets You Hear Your Rig Exactly as It Is

Pedalboard outputs behave very differently from a guitar or bass plugged directly into a traditional DI. High output levels, stacked gain stages and complex pedal chains can easily overload standard direct boxes. Designed to handle powerful signals, the PCH maintains your sound with complete accuracy and no unwanted coloration.

Running on 9VDC, the signal is internally boosted to 24V, giving the unit enormous headroom and making it virtually unclippable. The result is a DI that remains clean, clear and consistent — no matter how loud or layered your pedalboard becomes.

High Performance Headphone Amp for Local Monitoring

One of PCH’s standout features is its integrated studio quality headphone amplifier. This allows you to:

• Practise silently
• Monitor your entire stereo pedalboard chain
• Hear exactly what the front of house engineer hears
• Check tones without involving anyone else

The headphone amp delivers enough power to cleanly drive high impedance headphones, making it ideal for professional monitoring on the go.

Pure, Transparent Audio for Any Genre

PCH is designed for complete signal integrity, offering:

• An extremely flat frequency response

• Full stereo operation
• Exceptionally clean conversion and output

From rock and metal pedalboards to ambient rigs, synth setups and acoustic instruments, PCH captures your sound with studio level accuracy.

Flexible Connectivity for Stage and Studio

PCH is ready for any performance or recording situation, offering:

No matter your setup or venue, PCH ensures consistent, noise free output.
