QuadraVerb 2 Reference Manual

The QuadraVerb 2 may be connected to a mixing console in several ways. Usually, it
is connected to the auxiliary send and return controls of the mixer. Another method of
interfacing is to connect the unit directly to the insert send and return patch points of
the channel that is to be effected. Still another way of interfacing the QuadraVerb 2 to
a mixer or recording console would be in-line across the output of your mixing
console. This last setup would be used only if you needed to effect the entire mix.

Using the Aux Sends

Generally, mixing consoles provide two types of auxiliary sends: pre-fader sends for
creating a cue (headphone) mix, and individual, post-fader effect sends. Typically, if a
mixer has more than two sends per channel (4, 6 or 8, perhaps), the first two sends
are reserved for the cue sends, while the remaining sends are used to feed effects. If
you are using a mixer with more than two sends, connect the QuadraVerb 2 using
post-fader sends.

Using a mixer’s aux sends poses a distinct advantage: each channel has its own level
control feeding the aux output (and eventually the QuadraVerb 2 input). This allows
you to make a mix of any channels you want to go to the effects by using the
individual channels’ aux send levels on the mixer. Most consoles also have aux
master controls, which set the overall level of each aux output.

Coming back from the QuadraVerb 2’s outputs into the mixer, you have two options:

connecting to dedicated return inputs, or

connecting to channel inputs.

The former is good if your mixer provides dedicated inputs (called returns) for effect
devices like the QuadraVerb 2. If your mixer does not have these, or you have already
used them all, consider connecting the QuadraVerb 2 to channel inputs or unused
tape returns.

Setting the Effect/Dry Balance

No matter where you connect the output of the QuadraVerb 2 into the mixer, you are
in control of the balance between the mixer’s channel inputs (the uneffected signal
being routed to the aux sends and the Mix) and the effect returns coming from the
QuadraVerb 2. The effect returns generally should only contain effected signal, and
not have any uneffected signal mixed with it (since these two signals are blended
together at the mixer).

If the Program you are using has the LR IN connected to the LR OUT, you may be
getting some dry, uneffected signal at the return. Generally, this is not desirable,
since the "dry" signal is already being heard through the original channel’s fader.
Therefore, in a mixer application you will want to cut the QuadraVerb 2’s Program’s
path which connects the inputs to the outputs. This can be done in three ways:

Go to the Mix parameters to bring down the direct level

Go to the Routing function of each program and remove the patch cords
connecting the inputs to the outputs

Turn on the Global Direct Signal Mute function. This is the easiest method.
