CONNECTION
Shown below is a connection example for the DB14b. The laptop
computer's stereo output is connected to the 3.5mm stereo input
of the DB14b via a stereo 3.5mm to 3.5mm cable.
NOTE: The Right and Left signal levels are adjusted
individually by the Right and Left Volume controls.
The XLR output is connected to a balanced low impedance input
on a snake or a mixer balanced input.
The two stereo RCA outputs may be connected to unbalanced
high impedance stereo, or individual right and left mixer inputs.
