The 2 input channels are summed and sent to the loudspeaker's output. These input channels are useful if you need to send a far-end signal and program audio to the loudspeaker. The MXA902's AEC reference is the same signal sent to the integrated loudspeaker and can't be changed. 19/38... -
Page 20: Intellimix Dsp
ERLE meter generally corresponds to the reference meter. Reference The MXA902's reference signal is set to the builtin loudspeaker, which is the sum of the 2 Dante inputs. When the loud speaker is on, the reference signal is post-DSP. Non-Linear Processing The primary component of the acoustic echo canceller is an adaptive filter. -
Page 21: Noise Reduction
The level of the MXA902's loudspeaker can also affect how well the AEC removes the reference signal from the mic's signal. Experiment with using a higher NLP setting when the loudspeaker level is higher. -
Page 22: Parametric Equalizer
Shure Incorporated Threshold When the audio signal exceeds the threshold value, the level is attenuated to prevent unwanted spikes in the output sig nal. The amount of attenuation is determined by the ratio value. Perform a soundcheck and set the threshold 3-6 dB above average talker levels, so the compressor only attenuates unexpected loud sounds. - Page 23 Shure Incorporated Copy, Paste, Import, and Export Equalizer Channel Settings These features make it simple to use effective equalizer settings from a previous installation, or simply accelerate configuration time. Copy and Paste Use to quickly apply the same PEQ setting across multiple channels.
