TECHNICAL INFORMATION

Latency- This is the time it takes to process your input into or back from the computer, measured
in milliseconds. The lower the latency, the lower the processing time and the harder the computer
must work. Once there is a certain amount of latency, you may hear an audible delay between your
input and output, which can make multitracking difficult. You can use the zero latency Monitor
Mixer of your INSPIRE 1394 to mix your live input (before it goes into the computer) with the
output of your software to avoid monitoring with latency.
Limit- This button will engage a limiter for the respective preamp (input 1 or 2). A limiter quickly
decreases the amplitude of an audio signal to avoid clipping the preamp, then slowly increases the
level back to normal.
When working with high output sources, or at high gain levels, you should
have the limiter engaged to prevent clipping.
Mute- This button will instantly silence the respective channel so it is not heard at all. This is
often used to isolate channels or to quickly silence a channel that is feeding back (see Feedback).
There is a mute button on each channel of the INSPIRE 1394 Monitor Mixer, as well as the
Speaker Output channel.
Pan- The pan of an audio signal refers to its position as it is heard in the stereo field, which is the
result of the amplitude of the signal sent to the left and right side of a stereo output. When a signal
is panned center, it will be heard equally through the left and right output. There is a panner on
each channel of the INSPIRE 1394 Monitor Mixer.
