The OPTIMOD 6300 is a high-quality, multipurpose stereo audio processor for digital radio (DAB +, HD Radio), digital television, network broadcasts, STL protection, satellite uplink protection, and digital mastering.

Thanks to versatile signal routing, the 6300 can also serve as a studio AGC with a fully digital signal path, and simultaneously as a talented headphone processor.

Because all processing is done using high-speed mathematical calculations within digital signal processing (DSP) chips, the processing has cleanliness, quality, and stability over time and temperature that are unmatched by analog processors.

Friendly interface

An LCD display and full-time LED meters make it easy to set up, adjust, and program the 6300, you can always see the measurement as you adjust the processor. Navigation is done using dedicated buttons, programmable buttons (whose function is context sensitive) and a large rotary button. The LEDs show all the measurement functions of the processing structure (two bands or five bands) in use.

Absolute control of maximum modulation

The 6300 precisely controls peak levels to prevent clipping or overmodulation in transmission media. The maximum level of the digital samples is controlled to more than 2%.

The 6300 implements "true peak" control by oversampling the peak limiter side chain at 192 kHz. This allows the 6300 to avoid clipping the analog signal path of a playback device by predicting and controlling the analog peak level by following the playback device's reconstruction filter with an accuracy of greater than 0.5 dB. For typical program material, the precision is 0.2 dB. Without actual peak control, analog clipping may occur even if all the peak values ​​of the digital samples are below 0 dBFS. This phenomenon has also been called "0 dBFS +".


Controllable

The 6300 can be remotely controlled by 5-12 V pulses applied to eight programmable and optically isolated "General Purpose Interface" (GPI) ports.
