ULTRA-DI PRO DI800 FUSE COMPARTMENT/VOLTAGE SELECTION: Before plugging the unit into a power socket, please make sure you have selected the correct voltage. Faulty fuses must be replaced with fuses of appropriate rating without exception. Some units feature a fuse compartment that can be operated in two different positions, allowing alternating between 230 V and 120 V. Attention: when using the unit outside of Europe (running on 120 V), you have to implement a fuse with a higher rating (see chapter 5 SPECIFICATIONS). 3.4 Taking a signal from a speaker output Sometimes, you want to take a signal directly from a speaker output, even though just one speaker output is available. By using the -30 dB switch on the DI800, you can connect your mixing console to an amp output (up to 3,000 Watts into 4 Ohms), without worrying that the DI800 will be damaged due to overload! If you are using a tube amp, you should connect a speaker or a similar load resistance to the LINK output. 3. APPLICATIONS 3.1 Connecting a guitar/bass signal Fig. 3.1: Guitar ß DI-box ß guitar amp/mixer This illustration shows the standard application of a DI-box. The signal feeding the amplifier remains unchanged; it is simply taken and routed into the amp. The low-impedance balanced signal is forwarded to the mic input of the mixing console. This application has its advantages particularly with bass guitars, because very few microphones can linearly transmit bass frequencies with high signal levels. If you are using effects, insert the DI800 after the effects device, so that you can monitor the effects via the PA system or the recording as well. 3.2 Converting output signals of a keyboard, DJ mixer, etc. Fig. 3.4: Connection to a power amp output + Before connecting to a loudspeaker connector, please make sure that the GROUND LIFT switch is in the ON position (no ground connection). This prevents accidental shorting of the amp output. Besides, the tip of the input connector should be connected to the speaker connector marked with red. The metal casing of the DI800 should in no case have physical contact to other equipment. 4. AUDIO CONNECTIONS + Please make sure that your DI800 is installed and handled only by people with enough technical expertise. Assure that those operating the unit during and after the installation are sufficiently grounded. Otherwise, electrostatic charge may alter the performance of your equipment or damage it permanently. Fig. 3.2: DJ mixer ß DI-box ß mixer This configuration lends itself to use with a keyboard, DJ mixer or other mono/stereo signal sources with line level, particularly when using long cables (e.g. connecting to a FOH mixer). The signal can be looped through to another amplifier via the LINK output. Thus, you get a monitor signal that is independent from the actual FOH signal (useful for keyboarders, DJs etc.). 3.3 Converting a microphone signal Average-quality microphones often feature unbalanced, highimpedance outputs. The DI800 lets you wire such mics to the mixing console using long cables without running the danger of inducing hum or interference noise. To this end, the microphone has to be connected to the input of the DI-box, and the DI-boxs output needs to be connected to the mic input on the mixing console.
