Transformer-isolated audio interface
The TAI-4 by Vermona is a 2x2 channel audio interface module for balancing signals coming from the modular system and for un-balancing audio signals that are sent to the modular.
Unlike other modules of that kind that work with electrical balancing, the TAI-4 has isolating transformers and thus features true balancing.
The upper part of the module consists of two identical channels with balanced XLR (female) connectors as inputs and 3.5mm mono-minijacks as outputs. Rocker switches serve for adjusting levels (0dB, +6dB, +12dB).
The bottom part has two output channels with 3.5mm minijacks as inputs and XLR-males as outputs. We find rocker switches for adjusting levels as well (-12dB, -6dB, 0dB).
