Using the Matrix Encoder/Decoder
1.Set up the mix roughly the way you want it.
Use the Surround Panner to place channels in the Surround mix, or assign channels to 
the individual LRCS outputs.
2.Activate the Matrix Encoder.
What you now hear is the encoded stereo mix, the way it will sound when played back 
on a normal stereo reproducer. If you open the Matrix Encoder control panel you can 
adjust the Gain of the Lt/Rt output by using the fader.
3.Activate the...

5.When you are satisfied with the result, Bypass the Matrix Decoder, or 
remove it from its effect slot.
6.Connect a master recording device to the stereo mix output and per-
form a mixdown as usual.
The resulting encoded stereo mix will now be compatible with common home systems 
that use the Pro Logic standard.
Using the Matrix Encoder with the 5.0 surround format
There are situations when you may want to mix for several Surround 
formats. For example, you...

Matrix Encoder
The Matrix Encoder is intended for Pro Logic compatible encoding of 
multichannel files. This is a process where a 4 channel Surround mix is 
“packed” into two channels for broadcasting or distribution on video 
tape, for example. The Matrix Encoder takes four separate inputs; left, 
right, center, and surround (LRCS), and creates two final outputs, left-
total and right-total (Lt and Rt).

Mix6To2
The Mix6To2 effect allows you to control the levels of up to six surround 
channels, and to mix these down to a stereo output. The pop-up menu 
contains a number of speaker arrangement presets that correspond to 
some default surround formats. The Mix6To2 lets you quickly mix down 
your surround mix format to stereo, and to include parts of the surround 
channels in the resulting mix.
•Note that Mix6To2 does not simulate a surround mix or add any psy-...

Mix8To2
The Mix8To2 effect allows you to control the levels of up to eight sur-
round channels, and to mix these down to a stereo output. The pop-
up menu contains a number of speaker arrangement presets that cor-
respond to some default surround formats. The Mix8To2 allows you to 
quickly mix down your surround mix format to stereo, and to include 
parts of the surround channels in the resulting mix.

Mixconvert
The Mixconvert plug-in is similar to the Mix6To2 and Mix8To2 plug-ins 
in that it is used to quickly convert a multichannel mix into another for-
mat that uses less channels when used as insert (for example convert-
ing a 5.1 surround mix to a stereo mix). Mixconvert can convert 
surround mixes into other surround formats such as mixing a 7.1 Cin-
ema surround format down to a 5.1 home theater format.
There are several obvious applications for this:...

•Whenever a multichannel audio track (more than three audio paths), group 
channel or FX channel is routed to an output bus or group channel with a dif-
ferent number of audio paths (e.g. 5.1 to stereo), a Mixconvert plug-in will be 
inserted in place of the panner in that channel.
•Whenever a multichannel audio track, group channel, FX channel or Output 
bus has an aux send that is routed to a Group channel or Output bus with a 
different number of audio paths,...

Interface
Overview
The plug-in’s interface has three different sections. On the left you 
find the input Configuration display with all parameters that directly af-
fect the input configuration. In the middle section the level parameters 
for the upmix/downmix are displayed. Above this, the preset controls 
can be found. On the right the output configuration is displayed with 
all parameters that affect the output configuration. Additionally, on the 
far left...

Faders for Surround, Center and LFE
These faders control the levels for the surround channels, front center 
channel and LFE channel in the upmix/downmix. The surround chan-
nels cannot be modified individually. For center and surround chan-
nels, the level can be changed between -∞ and +6 dB. For the LFE 
channel it can be changed between -∞ and +10 dB, since in some 
mixes the LFE channel may be attenuated by 10 dB (see page 91). 
The names Surround, Center...

As a general rule, you should be careful when using phase shifts, as 
they might have negative repercussions on the frequency spectrum and 
the level of the downmix. Also, when you generate matrixed downmixes, 
you should avoid introducing additional phase shifts, since these would 
prevent the decoding of the mix for different speaker configurations.
Toggling between parameter sets
You can use the Memory, Toggle and Clear buttons to toggle be-
tween two...
