Figure 2 8 Auto scanning BBE SOUND From the BBE Sound s website BBE HD Sound is defined as BBE High Definition Sound compensates for phase and amplitude distortion restoring the brilliance and clarity of the original content material The BBE High Definition Sound process begins by applying a linear phase shift across the full frequency range of the signal which allows the speaker system to reproduce the transients and harmonics in the correct order The BBE process then compensates for speaker amplitude distortion by progressively boosting lower and higher frequencies and doing so within the context of the phase correction process This efficiently creates a fuller richer sound without excess equalization KeyStone working together with BBE Sound Inc implemented BBE Sound in the core of the module Sixth Logic DAB FM Development Board User s Guide Page 15 www sixthlogic com 2 7 1 BBE HD Sound Setting BBE HD Sound feature in KeyStone s module when properly tuned will deliver superior sound however when it is not properly tuned or over tuned the sound will cracked and distorted Set the master volume to half then press the setup eq button on the demo software to bring up the configuration screen Follow the steps below to achieve a first good result 1 Set Head Room to 12db 2 Click on BBE button to enable BBE 3 Slowly increase Hi to acceptable sound or slightly before it started to sound distorted 4 Slowly
