Galileo Callisto is a new loudspeaker management system recently introduced as part of Meyer Sound's new flagship LEO linear large-scale sound reinforcement system. Following LEO's successful rollout, Galileo Callisto is now available for users of Meyer Sound's M Series line array products, in addition to LEO customers.
To learn about the new features in Galileo Callisto and how it is different from the original Galileo, here is a Q&A with two product managers at Meyer Sound: Luke Jenks and Todd Meier.
Q: Galileo Callisto is…?
Luke: Galileo Callisto is our latest digital signal processing and management system with new specialized tools for calibrating line array systems. Galileo Callisto is built on the Galileo foundation, which provides Meyer Sound customers with a popular set of tools for delay and filtering. Galileo Callisto continues the Galileo legacy with new options that make precision calibration of arrays faster and easier.

Q: Why now?
Todd: Galileo was introduced in 2004, and its combination of Composite and Graphic EQ has become an intrinsic tool for corrective and creative equalization in calibrating systems across a variety of applications. As projects using our line array loudspeakers continue to grow, so has the use of Galileo in complex line array systems. This has led to more customer requests for specialized features for calibrating line arrays, and Galileo Callisto is the answer to these requirements. Its release is perfectly timed with the launch of our new flagship LEO system, which Galileo Callisto is a part of.
Q: How do customers know if they should buy a Galileo or a Galileo Callisto?
Todd: For those who rarely use and combine line array products, Galileo is a wonderful tool for organizing and managing systems, including many distributed audio and cinema systems. The new features in Galileo Callisto cater to specialized demands related to precision system calibration for Meyer Sound arrays, including LEO-M and M Series loudspeakers.
Q: What are some of Galileo Callisto's core new features for line array users?
Todd: A number of input and output processing changes have been made to the Galileo Callisto and the Compass control interface. Two exciting additions for Meyer Sound line array users are delay integration and U-Shaping.
TruShaping in Galileo is a huge success because it is a smooth and gradual filter. Our new user-defined shaping filter, named U-Shaping, works like a sculpting tool with adjustable gain, width, and slope.
In addition, Galileo Callisto's matrix has a direct routing option that allows users to address a single output individually, providing a greater degree of control for each element in a sound system. Galileo Callisto also adds additional options to high- and low-pass filters and allows both filters to be used simultaneously; this will allow greater flexibility for artistic sound design.
Q: What is delay integration?
Todd: Delay integration provides a quick alignment tool to match the phase characteristics of MICA to LEO-M. The goal is to ensure a coherent summation when combining different elements. Delay integration settings are currently available for LEO-M with MICA as downfill, MILO, M'elodie, and MINA.
Q: Galileo Callisto came to market eight years after Galileo. How does Galileo Callisto fit into the Meyer Sound product portfolio?
Luke: Galileo Callisto supports users of Meyer Sound products that range from the M1D—introduced in the early 2000s—to the new LEO. It is a great example of how the company views our customers as long-term partners. While we spend a lot of R&D energy to solve new problems with systems like CAL and Constellation, we are also investing in tools like Galileo Callisto that add value to all of our M Series systems, which have been a foundation of Meyer Sound's growth in various markets for the past 10 years.
The new U-Shaping filter provides a sculpting tool for users to efficiently adjust the gain, width, and slope.
Q: Was it difficult to make the complex simple in Galileo Callisto?
Luke: Making these many powerful tools simple to use is certainly an interesting dilemma. Power users demand more specialized functionality and flexibility. Yet, as manufacturers, we have the responsibility to make sure that our tools are intuitive and easy to deploy. These two requirements often seem to be at odds with each other.
Luckily we're blessed with an enthusiastic group of users, and they work closely with our tech support team that is very active in the field. User input has been critical in creating a tool that is powerful and fast to use without a steep learning curve.
Todd: Even when a product is designed for ease of use, we can't stress enough the importance for users to familiarize themselves with the project and the product, along with audio basics—from array theory and phase relationships to measurement and analysis. That's the only way to get the best result from any system. Our education program and tech support are on hand to help with this effort.
