mixer in this fashion is a good way to avoid latency
(delay) issues that can arise when using audio
software on a computer. See chapter 8, “Reducing
Monitoring Latency” (page 45) for more
information about dealing with latency.
Using the 4pre as a stand-alone mixer
When the 4pre is not connected to a computer, it
can operate as a stand-alone mixer, and you can
use the front panel to control your mix.

ten-segment MAIN OUT ladder LEDs provide
visual feedback as you turn the knob.

The Line Out LEDs (Figure 6-3) indicate output
activity on the quarter-inch Line Out 3-4 jacks.
The SPDIF LEDs (Figure 6-3) indicate input and

The INPUTS meters provide five-segment
metering for the mic/instrument combo jacks.
