SDI-202 Stereo Active DI Box
Warning
Every person involved with the installation, operation and maintenance of this system has to:
be qualified
follow the instructions of this manual
Description
The SDI-202 provides two independent high quality active interfaces, that lets you connect instrument,
line, or speaker level signals to a mixer or other balanced inputs. The instrument mode has a high
impedance input, which makes it possible to connect an instrument with a high output impedance, like
an electric guitar or acoustical guitars with a piezo-ceramic pick-up element. This mode also allows you
to connect electric devices with an unbalanced output like a keyboard or Dj mixer. The RCA inputs are
ideal for this kind of setup. It also has a speaker mode, which allows you to connect guitar amplifiers
direct with the SDI-202. The SDI-202 has a very clean and neutral sound with a wide variety of signal
sources and over long signal runs in high noise environments. The SDI-202 will provide an even frequency
response on any input signal connected, with the benefit of cancellation of interference, hum and buzz.
