StrymonPCH X2 Stereo Active DI Isolator
1/3
Independent shopping perspective
The Korena take
PCH-X2 puts two independent, transformer-isolated active DI channels in one compact enclosure for stereo instruments, modelers, and other dual-output rigs. Each channel accepts a 1/4-inch input, sends a balanced XLR output, and provides a non-buffered Thru connection for an additional amp or monitor feed. The Sum switch combines left and right at the left output when a mono destination is required. Per-channel ground lifts and selectable high-pass filters handle routing choices, while a left-output phase switch addresses polarity adjustments. It runs on 48V phantom power per channel.
Strong match
Who this is for
- Sending stereo keyboards, pedalboards, or modelers to balanced XLR inputs at front of house.
- Combining left and right inputs at the left output for a mono destination without repatching.
- Feeding an amplifier or monitor through Thru outputs while also sending balanced signals to a mixer.
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Sum switch
It merges the left and right inputs and sends the result to the left output.
Detail 03
High-pass filter: Off, 80Hz, 240Hz per channel
Each channel can be left full-range or set to either listed cutoff.
Detail 04
Ground lift per channel
Each channel has its own ground-lift switch for reducing hum.
Detail 05
Phase switch on left XLR output
Polarity can be reversed on the left output.
Detail 06
3 mm extruded aluminum chassis with 5 mm ribs
The enclosure uses extruded aluminum and reinforced ribs, with an awning-style protective design.
Final check

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can it turn a stereo source into a mono feed?
Yes. Its Sum switch combines left and right inputs and routes them to the left output.
02Does each channel have a ground lift?
Yes. Ground-lift switching is available separately on both channels.
03Can I feed an amp and a mixer at the same time?
Yes. Each channel has a non-buffered Thru output alongside its balanced XLR output.
04What powers the PCH-X2?
It uses 48V phantom power, with 5 mA consumption per channel.
