BALANCED OUTPUT - Male XLR connector. BATTERY/PHANTOM - Switches S direct from phantom power to battery operation. LEVEL - When engaged, the level is switched from instrument GTR to amplifier speaker SPR level. OUTPUT/LINK - 1/4" output for passing the input signal through to a stage amplifier or monitor system. BATTERY COMPARTMENT - Houses 6 7 3 4 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. 3 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 directs 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. · · · Connect the output of the guitar or bass to the S directs INPUT. Connect S directs OUTPUT/LINK to the input of the guitar or bass amplifier. Connect S directs BALANCED OUTPUT to the input of main PA mixer. 4 Operating the S direct NOTE: To avoid annoying pops and clicks be sure to mute (or turn down the volume control) of your mixers output while connecting the S direct, or when switching from battery to phantom power.
