BTM Sound has added a complete in-ear monitoring system based on Shure’s AD PSM range to its inventory. The choice of this ecosystem responds to the need to deliver maximum RF reliability, robustness in demanding environments, and top-tier sound quality for live and touring applications.
The configuration incorporated by BTM Sound includes AD PSM transmitters and receivers, as well as charging stations, providing a standard setup of eight in-ears with the flexibility to expand up to 16 stereo mixes without compromising spectrum management or system stability.
The combination of the different components ensures optimal spectrum management, minimal latency, and stable performance even in high-density RF environments typical of professional events.

BTM Sound continues to strengthen its commitment to next-generation technology with the addition of Shure’s Axient Digital PSM system to its technical inventory. With this investment, the company expands its wireless ecosystem geared toward high-demand RF productions and large-scale environments.
Xavier Morell, General Manager of BTM Sound, outlines the key factors behind this strategic decision and the role the new system plays within the company’s technical infrastructure.
What criteria led BTM Sound to choose AD PSM over other solutions on the market?
For the company, investing in technology such as AD PSM is not merely a catalog decision, but a strategic choice based on reliability and innovation.
Our priority is always to make the leap to the most advanced technology on the market. Choosing Shure Axient Digital allows us to offer a level of reliability and technological performance that no other solution can currently match.

What types of events or productions will the new system be used for?
The system is intended for high-performance productions: major festivals, national tours, and high-level corporate events, where signal quality and robustness are critical factors. “It is a safe bet for the most demanding environments”.
What has been the initial feedback regarding RF quality and spectrum management?
The initial feedback has been very positive. “The AD PSM’s ability to make efficient use of spectrum space is impressive. It gives us complete peace of mind when coordinating frequencies in complex and congested environments”.
What operational advantages do low latency and remote control provide?
Both features represent significant improvements in workflow efficiency.

The virtually non-existent latency is key to artist comfort. In addition, remote control via ShowLink technology allows us to monitor and make adjustments in real time, delivering operational agility and efficiency that truly makes a difference.
What role does AD PSM play within the company’s current microphone and in-ear ecosystem?
The system completes the company’s wireless infrastructure based on Shure solutions. “It is the final piece of the puzzle. We have been working with Axient Digital microphones for some time, and full integration with Wireless Workbench allows us to manage the entire Shure ecosystem — microphones and in-ears — from a single platform, ensuring maximum precision in every production”.
