Gate Count, Ambience IQ-AMB-5 only | Crown IQSMX-6, IQAMB-5 specs

AMB-5 /SMX-6IQ Mixer/Multiplexer

If the level audibly drops each time the gate opens, try a lower value for Idle Gain. Idle gain should never be set to a value greater than Max Gain. Control range is from –100 to +25 in 1/2- dB steps.

•Reaction Time: the time in seconds to adjust gain 10 dB toward the necessary gain structure to obtain the desired average output level. Control range is from 0.2, to 30 seconds.

•Auto Level Gate Function: a global setting that may be set to “Open To Idle Gain” or “Open To Last Position.” When set to “Open To Idle Gain” an input will initially gate on to the Idle Gain setting and the auto level feature will take over from that point. When set to “Open To Last Position” the auto level feature remembers the gain of the VCA at the time the input last gated off so that gain goes back to that level the next time the gate opens.

4.2.10 Output Compressor

The Output Compressor/Limiter function keeps the output from exceeding a predetermined level. It's especially valuable when used as an output limiter for the protection of amplifiers, loudspeakers and other audio equipment. Compression of the signal at each input occurs only when the mix exceeds the limit threshold. There are six parameters which con- trol this feature:

•Compressor: a master ON/OFF switch for each output that enables or disables output compression for that output.

•Limiter: an ON/OFF switch for each VCA that configures which inputs may participate in out- put compression.

•Limit Threshold: used to set the peak signal level above which compression occurs. Con- trol range is from –100 to +25 in 1/2 dB steps.

•Compression Ratio: controls the amount of compression that is applied for every step over the Threshold. Choices are 1:1, 2:1, 4:1, 8:1, 16:1, 32:1, infinity:1.

•Release Time: determines how long it takes for the gain to return to normal when the level drops below the Threshold. Control range is from 0.2 to 30 seconds.

•Max Gain: the gain setting of the input when no compression is active. Control range is from – 100 to +25 in 1/2-dB steps.

4.2.11 Gate Count

The Gate Count function keeps track of how many gates are open at a time, and provides feedback control when a large number of inputs are open. The Gate function must be on for the Gate Count to operate. There are four parameters which control this feature:

Gate Count Master: a master ON/OFF switch for each output that enables or disables gate counting for that output.

Gate Count: an ON/OFF switch for each VCA that configures which inputs may participate in the gate count.

Gate Count Level: determines how much each input is attenuated as more gates open. When only one mic in a count group is active, there is no added attenuation. Each additional open mic increases the attenuation by the “Count Level.” Control range is from 0.5 to 16 dB.

Max Gain: the gain setting that will be used when the gate is “open,” and no further attenuation is indicated. Control range is from –100 to +25 in 1/2-dB steps.

4.2.12 Ambience (IQ–AMB-5 only)

The Ambience function monitors the ambient sense input (Input 6) and automatically adjusts the mix output level of Channel 1 up or down accordingly. This enables the IQ–AMB-5 to automatically mix and control the overall loudness in an environment with background noise levels that vary. Functionally, the ambience function operates after all other functions have processed the audio signals. There are six parameters which control this feature:

Ambience: an On/Off switch that enables of dis- ables the Ambience feature

•Attack Time: determines how rapidly the Am- bience function will begin to increase the out- put level of Channel 1 above the Ambient offset level once the level of Input 6 exceeds the Threshold. Control range is from 0.2 to 30 sec- onds.

•Decay Time: determines how rapidly the Am- bience function will begin to reduce the output level of Channel 1 while the ambient sense in- put level is dropping. Control range is from 0.2 to 30 seconds.

•Expansion Ratio: determines how much the gain of output Channel 1 will increase for every
