Terratec SINE DI4 User Manual

Cables have the job of transporting

signals from Point A to Point B. Unfortu-

nately, they frequently pick up noise along

the way. Unbalanced connections — as

can be found on nearly all synthesizers,

basses and guitars — are especially

sensitive to interference from power

cables, unlike the balanced signals from

microphones. The result: unpleasant hum.

The four-channel SINE DI 4 active direct-in

box is the answer to this problem.

Nomen est omen — "DI" stands for "direct

inject", letting you connect unbalanced

signal sources directly to the balanced

microphone inputs of your mixer. The

electrical isolation of input and output

signals in the SINE DI 4 makes it possible.

It also features ground-lift switches to kill

hum caused by potential differences be-

tween devices.
