ADi6 dB MAX Direct Box dB MAX Active Direct Box EL ALL PAR -22 ADi6 + 3 2 OUTPUT 1 INPUTS -12 -8 -3 ADi6 dB MAX Active Direct Box · Uses 9-Volt or standard phantom power for power supply · Ground Lift for "hum" reduction · Variable Attenuation for precise level control · Parallel or Mixed input jacks The ADi6 is an active direct box for converting a high impedance signal such as a direct out from a bass amplifier, to a low impedance signal such as a snake input and a mixer's microphone input. The Ground Lift is provided to reduce possible ground hum or buzz, a variable Attenuation control provides precise level adjustement, and the unit may be powered via 9 volt battery, or phantom power from a mixer.

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. 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. BATTERY switch: When pressed in, the ADi6 will be powered via a 9 volt battery, the ACTIVE LED will light. 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. The ATTENUATION is at 0 dB, and the GROUND LIFT is in meaning the chassis ground is connected to pin 1 of To Mixer the XLR jack. If the unit is to be Microphone powered via 9 volt battery, the Input BATTERY switch should be in, if the unit is powered via phantom power from the mixer, the BATTERY switch should be 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.
