Thanks for choosing the Countryman Type 10S Stereo Direct Box. We’re confident you’ll
find it the most accurate and rugged two-channel direct box available.
The Type 10S DI uses an innovative circuit design to deliver unparalleled performance:
total harmonic distortion (THD) less than 0.001%, 122 dB of dynamic range, flat and
extended bandwidth from 10 Hz to 50 kHz (+/- 1 dB), less than 2 degrees of deviation
from linear phase for the entire audio range, and imperceptibly low inter-channel cross-
talk. And all of this performance comes in a rugged, nearly indestructable housing, built
to last for years on the road.
This booklet describes how to use the Type 10S to get the best performance in a variety
of different applications.

The Type 10S includes several different connector
options on the input to accomodate a wide variety of
applications. Here are some things you should know
about the various connectors:
• If phantom power is available, all of the connectors
can be used. For battery operation, only the 1/4” jacks
are available, since the battery turns on only when you
connect a mono 1/4” plug to Channel A.
• The 1/8” jack is wired such that the tip routes to
Channel A, and the ring to Channel B.
• The 1/4” inputs have an input impedance of 10MΩ
since they are often used with piezo pickups, or other
high impedance sources. The RCA and 1/8” inputs
have an input impedance of 20kΩ since they are almost
always driven by low impedance sources.
