[. . . ] The ADi6 is a durable and cost effective unit designed to take a high impedance line-level or speaker level audio signal and convert that signal to low impedance. DESCRIPTION INPUT jacks: Two 1/ 4" Tip Sleeve unbalanced jacks for connection to the ADi6 high impedance 3 Active Direct Box signal to be bal2 + anced. OUTPUT 1 INPUT switch: Selects Parallel input INPUTS -8 -3 -12 or Mixed input. In Parallel mode, the -22 tips of the two input jacks are shorted -40 GND LIFT dB 0 together providing PARALLEL ON you with a "passLIFTED OFF/PHAN MIXED through" jack. In Mixed mode, a series of resistors are inserted in line, allowing a stereo signal to be mixed to mono. ATTENUATION control: Adjusts the input level to the ADi6. Fully clockwise, the ADi6 does not attenuate the incoming signal. As the control is turned counterclockwise, the input signal is attenuated by the indicated amount. GROUND LIFT switch: When pressed in, the chassis ground is connected to pin 1 of the XLR Output. When the switch is out, the chassis ground is disconnected. BATTERY switch: When pressed in, the ADi6 will be powered via a 9 volt battery, the ACTIVE LED will light. When out, the unit is powered via phantom power. OUTPUT jack: Balanced XLR jack for connecting to the input of a mixer. dB MAX Active Direct Box LLEL PARA ADi6 + 3 2 OUTPUT 1 INPUTS -12 -8 -3 dB MAX A PAR LLE -22 GND LIFT -40 PARALLEL MIXED dB 0 ON LIFTED OFF/PHAN This example shows the ADi6 connected to an instrument. The INPUT switch is in, the unused 1/4" jack may be connected to an instrument tuner. [. . . ] A stereo source is shown connected to both 1/4" inputs, and the INPUT switch is out. This mixes the right and left signals to mono, and balances the combined signal to be sent to a mixer. The ATTENUATION control, GROUND LIFT switch, and BATTERY switch should all be set for proper operation.
