Compression Frequency dependent amplification for loud and soft input sounds It is possible to separately adjust the gain for loud (90 dB) and soft (40 dB) input sounds in up to 8 channels.

    SYLLABIC (or fast compression) Syllabic compression adjusts the gain for instantaneous fluctuations that occur within speech. It operates with a fast level meter using an attack time of 10 ms and a release time of 100 ms. It should be used in frequency bands where a user has a strongly reduced dynamic range (moderate to severe hearing loss) which is more common in the high frequencies.
