Direct Monitoring
16 E-MU Systems
DIRECT MONITORING
Direct monitoring allows you to monitor inputs without having any software
open. It can also be used as an alternative to software monitoring if you desire the
lowest latency monitoring possible.
When using a computer for digital recording, an audible time delay occurs while
the audio signal is being input to the computer, processed by the software and then
returned to the output for monitoring. This time delay is called Latency.
Latency becomes a problem when you have to use high buffer settings to conserve
CPU resources. Because the 0202 USB 2.0 has hardware direct monitoring, you can
enjoy zero latency regardless of your buffer setting.
NOTE
Direct monitoring is not
available at 176.4 or
192 kHz.
The Direct Monitor feature connects the input signals to the output when recording
so that you can hear your performance without delay. The Direct Monitor level
control lets you adjust the volume of the input signal in relation to the recorded
tracks.
Direct monitoring is controlled manually from the Direct Monitor switch on the
0202 USB 2.0. It’s not necessary to turn it on in your recording application
Direct Monitoring vs. Software Monitoring
Direct monitoring is lower latency and can also be used without software running
(or even without a computer!).
Software monitoring has the advantage of allowing audio effects or EQ added in
the host software to be heard on the output. Its roundtrip latency depends on what
latency is chosen in the ASIO configuration. If you choose to software monitor,
make sure to disable direct monitoring. If both are enabled, you will experience a
‘comb filter’ or doubling effect.

Latency (delay)
Direct Monitoring allows you to listen to the direct sound of your instrument during
recording, without the delay incurred by going to the computer and back.
