Operation
Connected to Instrument
The ADI-2 can be used to connect the unbalanced output of an instrument or line level device (eg. guitar, bass, synthesizer, effects module, another mixer) to the balanced input of a mixer or amplifier. Set the GUITAR/SPEAKER (3) switch to GUITAR for this application. If you desire to send the original unbalanced signal on to a mixer or amplifier, use the 1/4" unbalanced output (5). The 1/4" output (5) is paralleled with the input, therefore, when using the 1/4" output (5), the input device and output device volume controls may need to be adjusted to acquire the desired level.
Connected to Amplifier
The ADI-2 can be used to connect an amplifier’s speaker output, or a speaker’s “daisy chain” output, to the balanced input of a mixer. Set the GUITAR/SPEAKER (3) switch to SPEAKER for this application. If your speaker has only one connector, the ADI-2 can be inserted between the amplifier and speaker using the 1/4" input (4) and 1/4" LINK OUTPUT (5) jacks.

Introduction
Congratulations for purchasing the ADI-2 2-Channel Active Direct Inject Box. This unique unit is the ultimate, multi-functional active DI box. The ADI-2 is indispensable for solving many audio mismatch and hum problems in numerous stage and studio applications.
•Simultaneous dual inputs and outputs for stereo or multi-source use
•Eliminates impedance mismatch problems and converts any sound source at almost any level (from guitar to speaker) into a clean, powerful hum-free, noise- free and interference-free balanced signal perfect for even extremely long cable runs
•Full-featured controls and connections include On/Off, Ground Lift, and Guitar/ Speaker Source Select input attenuation switches; unbalanced 1/4" TS Input and Parallel Link Output jacks; and servo-balanced XLR Output jack.
•Parallel link output allows ultimate hookup flexibility by enabling applications such as connection to the input of the backline or monitor amplifier.
•No compromise circuit design and stringent component selection provide absolutely flat, full frequency response across the entire audio spectrum, and negligible distortion for the most natural, powerful audio available.
•Portable aircraft aluminum extruded case for ultimate roadworthiness, long life and reliability
•Powered either by console’s +48V phantom power or internal 9V battery
