Overview
TOPPING builds the E2x2 OTG as a USB interface with an ultra-linear preamp, a headphone amplifier and an optical output. It works with a computer or a smartphone, and the title promises zero-latency monitoring.
Mobile streaming from a phone and recording at the top sample rate cover the main uses, and the supported-software list is wide. The limitation is a listing with no descriptive text and nothing on the layout of inputs and outputs.
Who it's for
Streamers, podcasters and guitarists who switch between a laptop and a smartphone. Anyone who needs full connection details, or who wants a larger channel count, should look elsewhere.
Pros and cons
- Works with computers and phones
- Headphone amp built in
- Wide software support
- No description in the listing
- Input and output layout not listed
Performance notes
A low-noise preamp is the foundation for microphone recording, and the headphone amp drives monitoring. Direct monitoring avoids delay during tracking. The optical output sends a digital signal onward to other gear.
