Powering S direct
The S direct can operate on a single 9 Volt battery or standard 24-48 volt phantom
power. Whenever phantom power is present on the XLR cable that is connected to
the Balanced Output, the S direct will automatically switch to phantom power and
disconnect the 9 Volt battery. The Phantom/Battery switch can be used to turn off the
battery power when the unit is not in use.

Operating the S direct
A direct box, or DI box, provides the facility for the direct insertion of an audio signal
into a mixer or recorder. The S direct offers a variety of DI solutions for live sound
and recording applications. You can connect all kinds of audio signals like guitars,
keyboards, outboard signal processors and even the high-powered speaker output
from an amplifier. The S direct enables you to tap off the signal from a guitar or bass
guitar and pass the signal from the Link output to the on stage amplifier without
affecting the original sound. This can eliminate the need for micing the guitar amplifier, which in many cases is preferable, especially with bass guitar. The S direct is also
very useful for connecting unbalanced signals from sources like signal DJ and submixers, effects processors and keyboards to a main PA or recording mixer. Unlike
passive direct boxes, the S direct is active (has a power supply), so you can rely on
an even frequency response on any audio signal you connect to regardless of its
output impedance. Also, the S directʼs balanced output provides a clean signal at a
low level so long runs of cable are possible. Another benefit from a balanced connection is Common Mode Rejection, which provides cancellation of the bad sounds
(hums and buzzes) while leaving the original signal pure.
Direct Insertion of an Instrument into a PA System
One of the most common applications for using a DI box is getting the signal of a
bass guitar into the PA system. Simply put, the low frequencies produced by bass
are difficult to mic, so use of a DI box is almost always preferable. In addition, the
signal going to PA system can be tweaked by the FOH (front of house) engineer,
without affecting the sound the musician dials up on stage. You can use S direct to
plug a guitar directly into the PA system as well, especially acoustic guitars with pickups and when using electronic guitar processors and modelers. Follow the diagram
and steps below to connect a guitar to a PA mixer.

Typical Instrument Hook-up
NOTE: To avoid
annoying pops
and clicks be sure
to mute (or turn
down the volume
control) of your
mixerʼs output
while connecting
the S direct, or
when switching
from battery to
phantom power.

Connecting to High Power Signals
The S direct provides the capability of tapping off the signals from amplifiers, such as the
output of a guitar amp or power amplifier. You can even use S direct to connect to the
speaker output of a consumer stereo system or boom box, for example, if you want to
sample some old records or cassette tapes.
NOTE: Be sure that the LEVEL switch is set to the AMP position before connecting the signal from the output of any amplifier.
Follow the diagram and steps below to connect a powered output of a guitar amplifier to a
PA mixer.
•
Connect the output of the guitar or bass to the guitar amp input.
•
Set the Level switch to the SPK position.
•
Using unshielded speaker cable, connect the guitar ampʼs speaker output to the S
directʼs INPUT.
•
Using another unshielded speaker cable, connect S directʼs OUTPUT/LINK to the
input of the guitar amplifiers speaker.
•
Connect S directʼs BALANCED OUTPUT to the input of main PA mixer.

Operating the S direct
NOTE: This example may
appear to be the same as
the previous, however in
this example, the S direct
is tapping the sound of the
instrument and amp, as
opposed to just the instrument itself.

Converting the Output of Unbalanced Devices
The S direct can be quite useful on stage or in the studio for connecting unbalanced
devices, particularly keyboards. The output levels of many keyboards are low, so their signals can benefit greatly by connecting their unbalanced outputs to the S direct. By doing
