HEADPHONES / LOCAL MONITOR and P/AFL SYSTEM
The Console Monitor System
The engineer is able to listen to any channel, mix or
matrix signal using stereo headphones and an
amplifier/speaker system connected to the local
monitor output. In addition the C output provides an
engineers wedge monitor feed when the console is
configured for monitor operation. All have
independent level control. The headphones are
connected by plugging in under the front armrest.
The source is selected as either the 2-track input,
main LR mix, main C mix, or LR combined with C
for listening to a 3 output LCR system using the
stereo monitor. Pressing any console PAFL or AFL
switch overrides this selection with a priority well
suited to live sound applications. The selected
source can be listened to in mono or stereo. All
monitor outputs automatically dim by 20dB when
the TALK switch is pressed.
The ML4000 features an intelligent P/AFL system
that provides extended monitoring capability. The
inputs can be selected as mono PFL or stereo in-
place AFL, the outputs as mono or stereo AFL.
Selection is auto cancel or add mode. How the
switches are pressed determines if they have a
latching or momentary function.
Together with the wedge monitor capability this
gives the engineer total and conveniently quick
monitoring of all sounds passing through the
console.
The Monitor Logic
• No switches pressed = quiet
• Main selection: 2-TRK overrides LR, C
• LR and C together = LCR in stereo
• Pressing AFL overrides the main selection
• Pressing PAFL overrides AFL and main
• Releasing PAFL restores AFL
• Pressing AFL cancels PAFL
• CLEAR ALL cancels all PAFL and AFL
• Input PAFL = mono PFL or stereo in-place AFL
• Output AFL = mono or stereo AFL
• Press related two together = stereo AFL
• Hold P/AFL longer than 1 second = momentary
• P/AFL selection is cleared on power down
• The L,R,C meters = main mix or P/AFL
• Pressing TALK dims all by 20dB
