Output Zone - Setup / Delay - QSC MP-M80 User Manual

Output Zones − Setup / Delay
Various utility setup functions for Aux and Main
output channels.
1. Setup Button – Selects the Setup screen
2. Stereo Link – Links adjacent channels for stereo
operation. Only odd / even linking is supported (1-2, 3-4,
etc.). Even / odd linking (2-3, 4-5) is not available.
About Stereo Linking:
Signal routing and summing for linked inputs and outputs
functions as follows:
• Mono input (source) to mono output (zone) – The mono
source signal is output from the zone as a mono signal.
• Mono input (source) to stereo linked output (zone) – The
mono source signal is routed equally to the odd and even
numbered outputs.
• Stereo input (source) to mono output (zone) – The stereo
source signal is summed and output to the zone as a
mono signal.
• Stereo input (source) to stereo linked output (zone) –
The stereo source signal from the odd numbered input
channel is routed to the odd numbered output channel.
The stereo source signal from the even numbered input channel is routed to the even numbered output channel.
3. Reset – Returns Setup parameters to factory default values.
4. Output Name – Displays the name of the output channel. Touch to display a keyboard and rename the output as needed.
5. Polarity – Engage to reverse the channel's polarity.
6. Channel Safe – When set to Safe, the channel will not be affected by a scene recall.
7. Min/Max Output – Sets a minimum and maximum level for the channel. These are the minimum and maximum settings that can be set from an
MFC or from the MP Manage app. On the MFC and MP Manage app, the Min setting is displayed as 0% and the Max setting is displayed as 100%.
8. Architectural Delay – is variable up to 100 msec and is displayed in feet, meters and milliseconds.
9. Delay Enable – Engages or disengages the Delay.
About Delay:
The output delay on the MP-M is primarily useful for "architectural delay". Architectural delay is used to align the arrival of sound from nearby speakers
to the arrival of sound from a more distant source. When the delay is set correctly, the listeners will have the impression that they are hearing the distant
source when most of what they hear is actually coming from the nearby speakers. To adjust the delay:
• Set the delay for the nearby speakers so that the distance equals the distance between the nearby speakers and the distant source. Note that the
source could be an acoustic source such as a piano, guitar or a talker, or it could be another speaker system.
• Get into the coverage area of the nearby speaker. While listening to the source and the nearby speaker, add up to 30 msec. of delay. You'll know it's
right when you're ear tells you that the sound is coming from the source.
• Precedence Effect (also known as Haas Effect) creates the illusion that we aren't hearing the delayed sound from the nearby speakers because we
heard the sound from the distant source fi rst.
