Nady ADI-2 Manual - Page 2

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.

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, noisefree 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 Contents Introduction ...2 Controls and Connections 3 Operations ...4 Connected to Instrument 5 Connected to Amplifier 5 Specifications ...5 2
