4 ULTRA-DI PRO DI800 User Manual 1. Introduction Be it on-stage or in the studio, musicians often look for ways to connect certain signal sources directly to the mixing console. Even though this approach has obvious advantages, there are still some technical hurdles obstructing its implementation. For example, keyboards seldom feature balanced outputs, and guitars can not be directly connected to mixing consoles because of the high impedance of guitar signals. A DI-box lets you directly tap into a high-impedance, unbalanced signal— for example, the signal between a guitar and a guitar amp. From there on, you can feed the signal directly to a mixing console. There are active and passive DI-boxes. A passive DI-box is more affordable, but its performance is highly dependent on the impedance of the equipment to which it is connected. When the impedance on the mixing console’s end changes, so does the impedance at the DI-box’s input. A passive DI-box only functions correctly when the impedance of the connected equipment is exactly specified (high at the input, low at the output). On the other hand, active DI-boxes, such as the DI800, are not bound by these limitations, since the signal located at the input is “buffered” by an amplifier. The input impedance of the DI800 is extremely high. It does not influence the sound source and has absolutely no effect on the signal flow though the DI-box. The output impedance is balanced and is very low, and the signal is far less susceptible to picking up noise. The ULTRA-DI PRO always transmits signals optimally, independent of the impedance of the connected equipment. In addition to being powered by a mains connection, the ULTRA-DI PRO DI800 can also run on phantom power provided by your mixing console. ◊ To avoid damaging your loudspeakers, always first connect the DI-box and only then open up the respective channel strip. 1.1 Before you get started 1.1.1 Shipment Your ULTRA-DI PRO was carefully packed at the assembly plant to assure secure transport. Should the condition of the cardboard box suggest that damage may have taken place, please inspect the unit immediately and look for physical indications of damage. ◊ Damaged units should NEVER be sent directly to us.

Control Elements The BEHRINGER ULTRA-DI PRO features eight identically built channels. The control elements described here refer therefore to all channels. (1) The INPUT connector is used for connecting unbalanced as well as balanced signal sources. (2) Because both INPUT and LINK connectors are wired in parallel, the LINK TRS connector can be used both as an input and as a direct unbalanced output of the INPUT signal. For the latter, you can for example connect LINK with the input of a monitor amplifier. (3) The unbalanced input signal can be tapped into at the UNBAL OUT TRS connector – after passing through the amplification circuitry (see (4) and (6) ). Essentially, the signal is identical to the signal located at the XLR output in the back; the only difference is that it is unbalanced and has therefore no Ground Lift functionality (see (5) ). (2) (4) (6) (1) (3) (5) (7) Fig. 2.1: Front panel control elements (4) The -30 dB attenuation switch increases the operating range of the DI800 considerably, from low signal levels of a high-impedance mic or a guitar, all the way to speaker connectors of a guitar amplifier. ◊ Use the -30 dB switch only when the DI800 starts distorting (and not the mic preamp). When this is not the case, avoid using this function, since the lowest amount of attenuation is desirable in order to obtain the lowest signal-to-noise ratio possible. (5) Using the GND LIFT switch, you can fully separate input and output grounding. Depending on how the equipment to which your DI800 is connected is grounded, using the GND LIFT switch lets you lower hum noise or ground loops. When the GND LIFT switch is depressed, the ground connection is interrupted (the LED is lit red). When the switch is in the PHANTOM OR MAINS POWER ON setting, the LED is lit green (when the GND LIFT switch is not pressed). (6) The +20 dB switch increases the input signal level by 20 dB. (7) Use the POWER switch to power up your DI800. The POWER switch should always be in the “Off” position when you are about to connect your unit to the mains. ◊ To disconnect the unit from the mains, pull out the mains cord plug. When installing the product, ensure that the plug is easily accessible. If mounting in a rack, ensure that the mains can be easily disconnected by a plug or by an all-pole disconnect switch on or near the rack. (11) (10) (9) (8) Fig. 2.2: Rear panel connectors (8) The BAL OUT connectors (1 - 8) are the balanced mic-level outputs of the channels 1 to 8. Use a high-quality balanced microphone cable to establish connection. (9) The mains connection is achieved via the standard IEC connector. A matching power cord is included. (10) Serial NUMBER. The serial number is located on the top of the unit. Please take a few minutes and send to us a completely filled out warranty card within 14 days of the original date of purchase. Otherwise, warranty claims may be rendered invalid. Or fill out the warranty information online at behringer.com. (11) 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 use a fuse with a higher rating (see chapter 5 “Specifications”). 6 ULTRA-DI PRO DI800 User Manual 3. Applications 3.1 Connecting a guitar/bass signal Microphone Input DI600 Out In Link Out Fig. 3.1: Guitar DI-box 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. L R In In Out Out Turn pan pots fully (counter) clockwise on microphone channels Fig. 3.2: DJ mixer DI-box 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, high-impedance 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-box’s output needs to be connected to the mic input on the mixing console. In Out Fig. 3.3: Microphone connection 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. -30 dB! In Out + (red / positive) - (black / negative) 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. 7 ULTRA-DI PRO DI800 User Manual 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.
