Installation and Set-Up
1 Priority Channel Configuration
Microphones allocated as Priority can gain access at any
time, normally the priority microphone is used by the Chair
Person of a conference for example to override the other
microphones on the system.
Press the Enter button to enter the configuration screen.
Using the Up/Down buttons choose 1.SetMic.
On each channel the priority is activated using the Enter
button.
When priority is activated, it will show the input as ON.
Move through each microphone setting via the Up/Down
buttons repeating the above until the desired priority is
achieved.
When	Priority	is	selected	on	any	channel	the	corresponding	
LED illuminates on the front panel of the console to visually
indicate	the	channel	status.	
It	is	possible	to	activate	all	channels	as	priority.	
From	the	1.SetMic	screen	move	the	cursor	via	the	Up/
Down	buttons	to	the	Manual.	screen.
	
Press the Enter button to change the setting between N.
(no priority) or Y. (all priority). This option will override any
individual channel settings if already in place, removing
this setting will also revert the mixer back to any previous
individual	settings.
In	 the	 Y.	 setting	 all	 the	 channel	 LED’s	 illuminate	 on	 the	
front panel of the console to visually indicate the channel
status.
			
2 Priority “State”
It is possible to show the priority status via the LCD panel
display.
From	 the	 menu	 using	 the	 Up/Down	 buttons	 select	
2.State.
	
Pressing the Enter button will provide a numeric list of
channels which are set to priority.
3 Reset
By using this function it is possible to clear all priority
settings	previously	set	on	the	mixer.			
From	 the	 menu	 using	 the	 Up/Down	 buttons	 select	
3.Reset.
	
Pressing	Enter	will	provide	the	option	to	reset	Y.	or	N.
	
If no priority channels are selected the AM 81 automatic
mixer will open only the first active channel to operate, only
one	channel	can	be	active	in	this	state.
When	 a	 priority	 channel	 is	 activated	 whilst	 a	 no	 priority	
channel is active then the priority channel will override,
reducing the non priority level by -40dB (this level can be
adjusted between -20dB and -40dB, with -40dB as the
default).
If	a	non	priority	channel	is	activated	whilst	a	priority	channel	
is active then the non priority channel will not become active
until	the	priority	channel	has	become	inactive.
When	only	priority	channels	are	active	then	there	will	be	no	
attenuation between active channels, they will all output
at	the	same	level.
If	the	system	is	configured	as	all	channels	with	priority,	the	
AM 81 will automatically adjust/attenuate the output level
to	prevent	feedback.
Note:	It	is	highly	recommended	that	the	maximum	number	
of channels set up with priority is 4. By limiting this to 4 the
possibility of feedback via the system is greatly reduced.
