7 [RELEASE] list box
Specifies the speed at which the limiter will release. If Manual is selected, a knob is
shown, allowing you to specify the setting in msec units. If Fast/Mid/Slow is selected,
the following settings will be made automatically according to the crossover’s HPF
cutoff frequency in the Speaker Processor settings.
• Fast............. 4 wavelengths of the cutoff frequency
• Mid............. 8 wavelengths of the cutoff frequency
• Slow............ 16 wavelengths of the cutoff frequency
❑ Speech Privacy
This function mixes environmental sounds and masking sounds to make it difficult for people
nearby to overhear conversation in a specific location.
On the MRX7-D, only one such function is provided on each unit.
Although there are two outputs for each mixed signal, these two consist of an output without offset
and an output with offset. By assigning these two outputs to alternating speakers, you can reduce
the unnatural sensation of skewed phase where the sound overlaps.
Before going online with the MTX/MRX system, select [Install Speech Privacy File] from the MTX-
MRX Editor’s [System] menu or MRX Designer’s [File] menu, and use “Install Speech Privacy File”
dialog box to install a file in the MRX.
