The Expander offers an easy-to-use solution to access the Teabox’s RJ11 (telephone) jack inputs. It is the best way to add 4 Combo (XLR/TRS) jacks to give you a full complement of 8 jacks. It also performs impedance conversion – good for using high-impedance sensors with the Teabox.

The expander is also available with a custom scaling option. When you order an Expander with the Custom Scaling Option, you will receive an email from us asking you for the voltage range of the sensors you are planning to use with the Expander. We will then custom build an Expander to match your sensors to the optimum range of the Teabox.
