microphone preamplifier and dynamics

two channel microphone preamplifier

The exciter is the opposite of the de-esser - it amplifies

the selected area of the frequency spectrum. It is good

for resurrecting an old recording, or for restoring the

dynamic range of an instrument, so putting life back

into it and letting it sit higher in the mix.

Controls

controls a band pass filter, which is a combination of

high- and low-pass filters on a single control. As this

control is adjusted, both filters change in unison,

blocking the high and low signals so that only a narrow

band of frequencies can pass between them.

Moving the control isolates different small parts of the

frequency spectrum. Move the control until you start

compressing the frequency range containing the

sibilance, or start amplifying the frequency range you

want to restore with the exciter.

High-pass Filter

The high-pass filter is provided to remove rumble and

bass lift on microphones, since the Red 7 is designed so

that it can be the only item in the signal chain between

a microphone and the tape machine. 

For more information on a using high-pass filter, see

the section on the Red 2 earlier in this guide.

The Red 8 provides two independent microphone

preamplifiers, as two separate channels. 

In use, the Red 8 is identical to the Red 1, so if you

need information on how to use any of its features,

refer to the section on the Red 1 earlier in this guide.
