Interfacing to a Mixing Console

The NanoVerb handles mono or stereo sends at all system levels. The input circuitry
of the NanoVerb can easily handle professional +4 dBu levels (+20 dBu peaks), while
having enough input and output gain to interface with the low -10 dBV signal levels of
home recording systems.
The NanoVerb may be connected to a mixing console in several different ways. It can
be used to effect multiple channels at once by using 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 a single channel that is to be effected. Still
another way of interfacing the NanoVerb to a mixer or recording console would be in-
line between the output of your mixing console and the input of a tape deck or power
amplifier. This last setup would be used only if you wanted effects on the entire mix.
Using Aux Sends and Returns
Generally, mixing consoles provide two types of auxiliary sends: pre-fader sends for
creating a cue (headphone or monitor) mix, and post-fader sends for effects units.
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 such as the NanoVerb. Connect the NanoVerb using post-fader sends,
so that when you fade a channel out, its effects will fade also.
Using a mixer's aux sends allows each channel to have its own level control feeding
the aux output (and eventually the NanoVerb input). You can 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.
But sending signal to the Nanoverb is only half the story. With a mixing console, the
output of the Nanoverb must be returned to the mixer and turned up in the mix before
you can hear it. Depending on the design of your mixer, you have two options for
returning the effected signal to the mix:
connecting to dedicated aux return inputs, or
connecting to channel inputs.
The former is good if your mixer provides dedicated inputs (called returns) for effect
devices like the NanoVerb. If your mixer does not have these, or you have already
used them all, consider connecting the NanoVerb to channel inputs (if there are any
remaining). This method gives you the added bonus of more panning options and EQ
on the effects.
No matter where you connect the output of the NanoVerb 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
NanoVerb. The effect returns generally should only contain effected signal, and not
have any uneffected or "dry" signal mixed with it (since these two signals are blended
together at the mixer). Therefore, it is necessary to set the mix so that only effected
("wet") signal is present at the NanoVerb's outputs. To do this, turn the Mix control all
the way to the right.
