The IDEA TEOd9 is a 4-input, 8-output professional loudspeaker management system designed for high-performance audio applications. It integrates advanced signal processing and control features to optimize loudspeaker systems, ensuring precise sound reproduction and protection. The device is housed in a compact 1U rack-mountable chassis, making it suitable for various professional audio environments.
Function Description:
The TEOd9 serves as a central hub for managing loudspeaker systems. It accepts up to four analog inputs (electronically balanced XLR) and one AES/EBU digital input, processing these signals through a powerful 64-bit multimode ALLDSP AM685 processor. The processed signals are then routed to eight electronically balanced XLR analog outputs. The system offers extensive control over audio parameters, including gain, delay, equalization, compression, and limiting, allowing for detailed customization of the sound output. It supports both analog and digital audio sources, providing flexibility in system integration. The device can be controlled via its front panel interface, featuring a rotary encoder and function buttons, or remotely via PC or MAC using the IDEA DSPControl software, which connects via USB or Ethernet. This remote control capability allows for real-time configuration, monitoring, and firmware updates.
