Owner's Manual
Introduction
Modular systems are just amazing. They are whatever you want them to be, as you
are the one who's responsible for the number and kind of installed modules. It can
be either a simple monophonic synthesizer or an extremely complex sound- and
e!ect machine.
The TAI-4 is an audio interface for your modular system that brings the internal
audio signals out of the system as well as external audio sources into the modular
system. We are aware of the fact that many modules already have audio in- and
outputs, so what's the reason behind making a special module with this
functionality?
Each of the TAI-4s in- and output channel uses an audio transformer that
galvanically isolates and balances the audio signal. Thus potential ground loops
were prevented, the signal stays clear of electro-magnetic interferences. The
TAI-4 should be the module of choice whenever you need to handle high-quality
audio signals.
We are proud to welcome you as VERMONA TAI-4 user. Enjoy the module and be
happy whenever using it during music production and performances.

Installation
The TAI-4 is compatible to eurorack modular systems and has to be connected to
the A-100 system bus for operation.
Follow the safety instructions and warnings stated in your A-100s
manual when installing the module.
Before installing the module be sure to disconnect the modular
system from mains!
Connect the 10-pin connector on the TAI-4s rear to the ribbon cable that comes
•
with the TAI-4. The color marked stripe on the cable is oriented to the bottom.
(see illustration 1)
•
Connect the other end of the ribbon cable to the 16-pin connector on the
eurorack style power distribution board of your modular system. The colored
stripe has to be oriented to the negative 12 volt supply line (bottom).
•
Use the screws that came with your TAI-4 to mount the module into the modular
frame.
Now connect the modular system to the mains and switch it on.

Control Surface Features
Input Section
The input sections features two identical input channels.
IN
(1)
balanced female XLR input
(2)
LEVEL switch with CLIP LED
With this switch you can set the appropriate
input level.
If it is set to "0dB" the channels output level
equals the input level. Settings "6dB" and
"12dB" increases the level by the
corresponding value.
The CLIP LED indicates too high input levels.
The signal doesn't distort as soon as it
illuminates, there is still some headroom.
OUT
(3)
unbalanced 3,5mm jack output
Output Section
The output section features two identical output channels.
IN
(4)
unbalanced 3,5mm input jack
(5)
LEVEL switch with CLIP LED
With this switch you can decrease the input
level.
If it is set to "0dB" the channels output level
equals the input level. Settings "-6dB" and
"-12dB" decrease the level by the
corresponding value.
The CLIP LED indicates too high input levels.
OUT
(6)
balanced male XLR output
