The Galileo Callisto 616 array processor is an elegant hardware and software solution for driving and aligning Meyer Sound loudspeaker array systems. The 2-space, rack-mount Callisto 616 includes six inputs, 16 outputs, and a fully digital Matrix processor. The accompanying Compass control software provides comprehensive control of all parameters from a Mac or Windows-based computer.
Designed as the perfect complement to Meyer Sound's M Series and LEO-M arrays, the Callisto 616 features delay integration for aligning loudspeaker arrays, user defined shaping filters, and simultaneous low- and high-pass filters for Subwoofer control.
The Callisto 616 offers an extensive equalization architecture that includes U-Shaping equalization, comprised of five bands with adjustable slopes, widths, and gain, and 10-band complementary phase parametric filtering, both available on outputs. TruShaping equalization, comprised of four bands equalization with adjustable widths and gain, is available on inputs.
Equalization parameters are easily edited in the Compass control software, with numeric entry or by graphically dragging frequency bands. Parameters can be adjusted while viewing multiple layers of equalization in a composite graphic plot to achieve the ideal equalization curve. The Compass software's intuitive user interface is the culmination of Meyer Sound's extensive experience optimizing complex loudspeaker systems.
The Callisto 616 features full digital operation with fixed latency across all output channels regardless of any applied processing. It can also be connected directly to the SIM 3 audio analyzer, providing complete measurement and control for integrated audio systems.

Established by John and Helen Meyer in 1979, Meyer Sound has been at the forefront of innovation in audio engineering for over two decades. From the outset, Meyer Sound looked beyond loudspeaker cabinet design to create totally integrated, systems-comprehensive solutions that encompass transducer design, signal processing, power amplification and even electroacoustic measurement systems. As a result, Meyer Sound's engineering teams have earned an enviable reputation for developing unique, innovative solutions to some of the most difficult problems confronting audio professionals. In fact, it is fundamental to John Meyer's philosophy that no component of a system should be compromised in order to compensate for variables "upstream" or "downstream." Instead, the entire system should be conceived, designed, tested, confirmed and manufactured as a whole to provide the optimum blend of audio fidelity, utility and long-term reliability.
Processor units, often simply known as a DSP audio processor, are a sound-processing device that alters the sound of auditory signals. The processing of the audio signals may be either digital or analog. The analog processing involves the direct operation of the electrical signal while the digital processing involves the mathematical operation on the digital representation of the audio signal. The audio signals are typically known as sound waves that are transmitted through the air. These sound waves are measured in decibels or bels. These audio signals need processor units especially in radio broadcasting because the processor units link the transmitter with the rest of the sound system devices. There are various methods involved in the processing of both analog and digital signals. These include the following: storage, compression, transmission, equalization, noise cancellation, enhancement, level compression, echo, filtering and many more. Analog processing is the physical alteration of the uninterrupted signal by modifying the voltage, the current or the charge with the use of electrical means. In earlier times, analog processing was the only method being used to modify signals before digital technology came into existence. With the evolution of computers and software, digital sound processing became the alternative to analog processing. The digital processor units use digital circuits like the microprocessors and computers to process audio signals. Digital processing deals with sound waves represented by binary numbers and deals with the sequence of these numbers. Nowadays, audio systems typically use the digital processing method because it is more powerful and proficient compared to analog signal processing.
