Chapter 4: Using the Sphere L22 System
In many ways using a Sphere microphone is like using any conventional microphone. However, Sphere
offers advanced features that are not possible with any other mic which require understanding a few
new concepts and techniques. This section presents these basic concepts so you can quickly get started
using your Sphere microphone system.
DAW Signal Chain
Figure 4-1 shows the correct signal flow using the mono Sphere plug-in. In most cases we recommend
routing the outputs from the Sphere L22 mic directly to the Sphere plug-in without any intermediate
processing, such as EQ, compression or panning. Generally, additional signal processing, including
other plug-ins or analog outboard gear, should occur after the Sphere plug-in.
Figure 4-1 Sphere signal chain with mono output plug-in
The Townsend Labs Sphere plug-in outputs in mono just like a conventional mic. However, the
Townsend Labs Sphere 180 plug-in routes the left and right mic models to the left and right outputs,
respectively.
Make sure to satisfy the following conditions:
• Both mic preamp channels must be set to the same gain, and this must be maintained all the way to
the input of the Sphere plug-in.
We recommend enabling gain linking for both channels (if your preamp supports it) to conveniently
maintain equal gain between them.
• Route the front and rear mic outputs to the left and right inputs of the plug-in, respectively.
• Although we generally recommend placing the Sphere plug-in first in the effects signal chain, it is pos-
sible to place effects ahead of Sphere if they apply identical processing to both channels and do not
impose obvious distortion or other significant non-linearities.
