STATUS-LED THRESHOLD AUTO / MANUAL
The status LED shows the operating mode of the threshold value setting (green = automatic setting of the threshold value, red = manual
setting of the threshold value, see also point 29). To change the operating mode, press and hold the push-button on the THRESHOLD
rotary encoder for approximately 2 seconds (one of the 3 LEDs AUTO / MANUAL, MASTER or LOCK will now flash red. If necessary, turn
the THRESHOLD rotary encoder until the status LED AUTO / MANUAL flashes red and now press the push-button of the THRESHOLD rotary
encoder again. If the push-button is not pressed within 10 seconds, there will be no change and the LED stops flashing.

STATUS-LED MASTER
When using a single AM8 automatic mixer, it must be configured as a master unit. When daisy-chaining up to 16 AM8 automatic mixers
using the LINK IN / LINK OUT interface on the rear panel of the device (see point 14), the device that must serve as the master unit needs
to be configured as the master unit. If the status LED MASTER is permanently green, then the AM8 automatic mixer is configured as the
master device, and if the LED is not lit, as a slave device. The audio inputs of all slave units of the AM8 automatic mixer in the system are
daisy chained to the line output master 1 and master 2 of the master unit (see DAISY-CHAINING). To change the operating mode press
and hold the push-button of the THRESHOLD rotary encoder for approximately 2 seconds (one of the 3 LEDs AUTO / MANUAL, MASTER or
LOCK will now flash red). If necessary, turn the THRESHOLD rotary encoder until the status LED MASTER flashes red and now press the
push-button of the THRESHOLD rotary encoder again. If the push-button is not pressed within 10 seconds, there will be no change and the
LED stops flashing.

STATUS-LED LOCK
To protect the device from accidental or unauthorised operation there are 3 lock modes available to block the operating elements of the
AM8 automatic mixer (the “POWER” operating element cannot be blocked). These 3 lock modes can only be selected via the management
software (see “PANEL LOCK” point in “SYSTEM SETTINGS”). Activate the selected lock mode by pressing the push-buttons of the operating
elements for channels CH 1 and CH 8 simultaneously for approximately 5 seconds. To deactivate the lock, press and hold the push-button
for CH 1 and CH 8 again for approximately 5 seconds. The status LED “LOCK” lights up green if the lock function is activated and is off if the
lock function is deactivated.
STARTUP
- Use only balanced cables for the connections of the AM8 automatic mixer.
- To avoid damage to the audio system caused by feedback etc., set the volume of the audio system to minimum during the change of settings
and gently increase the volume.
- Since the AM8 automatic mixer is a 19” device with one height unit, the features, settings and displays that are available or visible directly
on the device are limited. Therefore, it is advisable to adjust all settings via the free AUTOMIX8 PC software. Also, visual checking of the input
and output channels and their settings is very comfortable and clearly arranged in the AUTOMIX8 software.
- In the standard setting of the AM8 automatic mixer, all audio inputs are set to microphone sensitivity, also, the 48 V phantom power is
enabled (individual activation / deactivation of the phantom power via the PC software is possible). Do not switch on the equipment until all
microphones are connected.
- Using the same type of microphone for all speakers makes it easier to adjust the settings and improves clarity. If different types of micro-
phones are used, be sure to adjust the input gain and equalizer settings accordingly.
- Make sure that all connected microphones are set to the same level, so as to ensure proper operation of the AM8 automatic mixer.
