Information

Orban’s all-digital OPTIMOD 6300 Audio Processor can help you achieve the highest possible quality digital audio broadcast, digital television, and netcast audio processing. Thanks to versatile signal routing, the 6300 can also serve as a studio AGC with an all-digital signal path, and simultaneously as a talent headphone processor. Because all processing is performed by high-speed mathematical calculations within Motorola DSP56367 Digital Signal Processing chips, the processing has cleanliness, quality, and stability over time and temperature that is unmatched by analog processors. OPTIMOD 6300 is descended from the industry-standard OPTIMOD audio processors for radio and television. Thousands of these broadcast-specific processors are attracting and holding audiences all over the world. They have proven that the “OPTIMOD sound” can attract and keep an audience even in the most competitive commercial environment. Because OPTIMOD 6300 incorporates several audio processing innovations exclusive to Orban products, you should not assume that it can be operated in the same way as less sophisticated processors. If you do, you may get disappointing results. User-Friendly Interface An LCD and full-time LED meters make setup, adjustment and programming of OPTIMOD 6300 easy—you can always see the metering while you are adjusting the processor. Navigation is by dedicated buttons, soft buttons (whose function is context-sensitive), and a large rotary knob. The LEDs show all metering functions of the processing structure (2-band or 5-band) in use. Push one of the dedicated buttons to “Recall” a preset, to “Modify” processing, or to access the system’s Setup controls. Absolute Control of Peak Modulation The 6300 precisely controls peak levels to prevent overmodulation. The maximum level of the digital samples is controlled to better than 2%. While primarily oriented toward “flat” media, the 6300 can also provide preemphasis limiting for the two standard preemphasis curves of 50μs and 75μs. This allows it to protect pre-emphasized microwave links, satellite uplinks and similar channels where protection limiting or light processing is required. It can also be used to process analog television FM aural carriers in television ap- plications because these are usually processed lightly compared to FM radio. Because its processing is configured to be most effective with “flat media,” the 6300 cannot provide extreme loudness for pre-emphasized radio channels. Use one of Orban’s Optimod-FM processors for this application.
