User manual BEHRINGER ADI21

[. . . ] In addition, the ADI21 functions as a standard ultra-transparent direct injection box when used in bypass mode. A DI (Direct Injection) box allows you to send a signal directly from an unbalanced, high-impedance output (like an electric guitar) and connect it directly to the balanced mic input of a mixing console. Whether for stage, recording, rehearsal or warm-up, BEHRINGERs V-TONE ACOUSTIC ADI21 is a natural choice for those who are seeking great tone with a simple set-up. + Before using the PAD switch, be sure that it is the mic preamp on the mixing console that is clipping and not the ADI21. You should only attenuate the output signal via the PAD switch if the CLIP LED of the mic channel lights up frequently or remains lit. [. . . ] When activated, the GND LIFT disconnects the ground connection between input and output. Depending on the grounding of the connected equipment, this can eliminate hum or ground loops. The -20 dB PAD switch attenuates the output level of the BAL OUT (see ) by -20 dB. It should be activated when the output level is too high for the microphone input of the mixer channel. Power supply connector Bottom of the ADI21 SERIAL NUMBER. The serial number of the ADI21 is located on the bottom. Open the lid to install or replace the 9 V battery (see also chapter POWER REQUIREMENTS). The ADI21 is powered as soon you insert a plug into the INPUT. The battery is disconnected when the plug is removed. For this reason, the ADI21 has no on/off switch. To prolong battery life, always disconnect the input when the driver is not in use. + BEHRINGER V-TONE ACOUSTIC ADI21 Use the DC IN connection to plug in a 9 V power supply (not included). For details please refer to chapter POWER REQUIREMENTS. SAMPLE SETTINGS APPLICATIONS Use with other instruments The ADI21 is not only for acoustic guitars. You can try it with other instruments (e. bass/electric guitars, keyboards etc. ) to create new sounds and enhance your music. Please make sure that the input level is not too high to avoid overloading the ADI21. Direct to a mixing console For live and studio applications you can connect the balanced XLR BAL OUT directly to a mic input of a mixing console. Be sure not to overload the input by using the gain control of the respective channel. For further information please refer to the users manual of your mixing console. Use without instruments You can use the ADI21 without an instrument as an outboard processor connected to an insert or an effect path (aux send/ return) of your mixing console to affect the signal of a particular channel. This way you can enhance existing tracks during mixdown. For further information please refer to the users manual of your mixing console.
