4. When using as an ALC it is better to use larger headroom letting the DSP control the gain With headroom of 42 dB you can only have an adjustment of 3 dB for the microphone preamplifier gain an input attenuation of O dB will set the microphone preamplifier gain to 42 dB and an input attenuation of 3 dB will set the preamplifier gain to 45 dB which is the maximum So the input attenuation will be mostly limiting the digital gain and act as a threshold avoiding the gain being too loud when the ALC is not limiting the gain during a silence When the input attenuation is controlled with the potentiometer the potentiometer will mainly act as threshold and allow fade IN OUT if a fixed input attenuation is set the potentiometer is disconnected from input gain control and no longer does anything Attack This parameter manages the speed with which the gain is limited With the immediate parameter also known as a brick wall the gain limitation will be done immediately avoiding the target parameter to be overshot When specifying a time from 125 microseconds to 2 milliseconds the attack parameter will act as a filter on high pitched frequency sounds such as keys being shaken for example This avoids closing the gain too much on unwanted sounds by the way the target level can be overshot on such sounds Typically the overshoot can be of 1 2 dB for 125 uS setting 3 4 dB for 250 uS setting 4 5 dB for 500 uS setting 5 6 dB for
5. 1 mS setting and 6 8 dB for 2 mS setting Delay This is the time period during which the ALC LIM process will not increase the gain after having limited keeping the gain constant even if the sound is too low This parameter avoids the gain pumping that is the gain increase during short silences This setting should be of the same order as the release parameter to be consistent and give a pleasant operation of the ALC lim Release This is the speed of gain increase when limiting gain is not necessary The speed is set by specifying the time that the ALC LIM process takes to reach the maximum gain starting from minimum gain This parameter mainly determines whether the ALC LIM process works as limiter set to minimum or as an ALC Ratio This parameter determines the target level function of the input level With a flat ratio the ALC LIM will only limit the gain when the signal would overshoot the target parameter giving a signal level that is independent of the input level Specifying a ratio other than flat allows having a more natural relationship between microphone signal and signal level A ratio of 6 1 for example will compress 6 dB into 1 dB That is the ALC LIM will start limiting when the signal is lower than the target level With headroom of 24 dB and a ratio of 6 1 the limiter start limiting when the signal is 4 dB 24 dB 6 before the target level if the target level is 2 dB the ALC lim will start limiting at
