PRODUCTION DATA
SpeakerGuard™ protects speakers, improves loudness, and limits peak supply current. If the output audio signal exceeds the limiter level, then SpeakerGuard™ decreases amplifier gain. The rate of gain decrease, the attack time, is fixed at 0.026 ms/dB. SpeakerGuard™ increases the gain once the output audio signal is below the limiter level. The rate of gain increase, the release time, is fixed at 1600 ms/dB. Figure 9-1 shows this relationship.
