A Dedicated Link in the Electro-Voice Wireless Microphone Ecosystem
The TXA was designed as a practical linking accessory: it converts a TA4F input connection into a male XLR output, allowing the use of an Electro-Voice compatible capsule on standard phantom-powered audio equipment. It fits within a range-consistent logic, with a design specifically optimized for Electro-Voice wireless microphones.
Who Is It For, and In What Applications?
The Electro-Voice TXA preamplifier is intended for sound technicians, videographers, content creators, and stage managers who want to obtain a clean and usable microphone signal on an XLR input. It is particularly relevant for mobile setups (shooting, interviews, conferences) where a reliable connection and controlled level are desired without adding complex electronics.
Key Features: Level, Filtering, and Connectivity
Built-in Pads for Cleaner Capture
The -6 dB low-cut pad at 100 Hz helps reduce handling noise, vibrations, and some low-frequency resonances. The -10 dB attenuator pad provides useful headroom to avoid clipping when the source is close or dynamic.
Compatibility to Observe
Warning: the TXA has been specifically designed to work with Electro-Voice wireless microphones. It will not work with TA4F-terminated microphones from other manufacturers.

Questions frequently asked
Is the TXA compatible with a TA4F microphone from another brand?
No, this preamp is specifically designed for Electro-Voice wireless microphones and does not work with TA4F connectors from other manufacturers.
What connectivity does the Electro-Voice TXA preamp use?
The input uses a TA4F connector and the output is on a male XLR. Phantom power +48 V is required for operation when connected to a compatible XLR input.
Does the TXA's high-pass filter reduce handling noise?
The high-pass filter attenuates frequencies below 100 Hz by 6 dB. This setting helps reduce vibrations, handling noise, and certain low-frequency resonances.
What is the purpose of the preamp's -10 dB pad?
The -10 dB pad provides additional headroom when the sound source is close or particularly dynamic, helping to prevent distortion.
What is the frequency response of the TXA?
The stated frequency response ranges from 20 Hz to 20 kHz. This range enables transmission of the Electro-Voice capsule signal to a phantom-powered XLR input.
