The GTA series are passive, transformer-balanced inline impedance converters. GTA adaptors are fully balanced, and all TRS inputs/outputs may be used in balanced or unbalanced
configurations, according to whether a TS or TRS plug is inserted into
The GTA adaptors are designed for use with
instruments wired for balanced output, but will also work with
unbalanced instruments, and can be used to create a balanced output with an unbalanced source (DI
applications). Using a standard TS cable, the GTA will operate as a standard passive DI adaptor.
