A 5110 DI Box
OPERATING INSTRUCTIONS
OVERVIEW
Direct Injection (DI) boxes are used to convert high impedance unbalanced devices like guitar pick ups to
a low level balanced output. This is done to allow signals to be fed over long distances without hum and
noise pick up. This model can be powered from either an external 12V DC source, a 9V battery, or
powered directly by the equipment it is connected to ie: Phantom powered. This DI box has inbuilt EQ or
tone controls plus an overall level control. Two 6.35mm mono connectors are provided for the input and
“loop out”, while a single 3 pin XLR is used for the output. An earth lift switch is provided to help
eliminate earth loops. A test switch is provided to test battery or phantom power availability. A “loop in,
loop out” power supply has been provided for powering other Redback Solutions products without the
need for individual 12VDC supplies for each unit.
