MDB-USB Stereo DIrect Box: Front Panel Features
1. USB Input
The built-in USB interface allows you to stream
audio from a computer and route it to the outputs
and headphones. It will show up automatically on PC
and Mac, no driver required!
Success here is partially dependent upon the
computer’s speed. It needs to be fast enough to run at
low buer sizes so that there is no noticeable latency.

4. Headphone Output
This 1/8" TRS connector supplies the output to
stereo headphones. It is the same signal that is routed
to the outputs. The volume is controlled with the level
knob.
The phones output follows standard conventions:
Tip = Lef channel
Ring = Right channel
Sleeve = Common ground
WARNING: The headphone amp is loud,
and can cause permanent hearing damage.
Even intermediate levels may be painfully
loud with some headphones. BE CAREFUL! Always turn
the level control all the way down before connecting
headphones or doing anything new that may aect the
headphone volume. Then turn it up slowly as you listen
carefully.
Fortune: Make a wise choice every day.
Lucky numbers: 1–10–12–13–20–36
