EXTC-SA Specifications

The EXTC is a guitar effects interface that enables the engineer to properly interface unbalanced guitar effects pedals with the world of balanced professional audio. It features a balanced line level input with variable guitar level send & receive controls for hi-impedance guitar effects.

Transformer isolation combined with class-A discreet electronics assures optimal signal transfer. This makes the EXTC the perfect interface for all kinds of effects that otherwise are difficult to use, cause noise or create unbearable hum.
