Microphone Pre-Amplifier.
Your FireStudio Tube is equipped with eight custom designed PreSonus X-
MAX microphone preamplifiers for use with all types of microphones including Dynamics, Condensers
and Ribbons as well as instruments and line level signals. The award winning PreSonus preamplifier
design is a Class A input buffer followed by a dual servo gain stage. This arrangement results in ultra
low noise and wide gain control allowing the FireStudio Tube user to boost desirable signal without
increasing unwanted background noise.
o
+22dBu Headroom.
The FireStudio Tube microphone preamplifier has +22dBu headroom.
This feature gives you wide dynamic range and excellent transient response characteristics.
• Line Inputs.
Channels 9-14 of your FireStudio Tube are line level inputs. They are designed to accept
up to a maximum input level of +20dBu. Use these inputs to connect your line level devices such as
synthesizers, amp modeling hardware, vocoders, etc. In general, line level devices have their own
volume control. As these inputs are for line level signal only, there is no trim control for them on the
FireStudio Tube. If you need to raise or lower the volume, the adjustment should be made from your
line level device.
A NOTE ABOUT VINTAGE DEVICES: Some older and vintage line level devices may not output at a
hot enough signal. If you find this to be the case, you should connect them to a direct box and plug
them into the microphone inputs instead.
