INTRODUCTION

The LD Systems AM 8 is an automatic 8 x 2 matrix mixer with balanced mic line inputs, 96 kHz/24 bit signal processing and a frequency
response of 20 Hz - 30 kHz. The Priority function of the AM8 automatic mixer can be switched on individually for each input; the total threshold
for channel activation is selected automatically or manually using the threshold controller. When the levels of input channels drop below a
certain threshold, these will be muted by the Automix feature. This means that for the transmission of a channel, background noise, feedback
and unwanted comb-filter effects from other active channels are effectively suppressed and the speech intelligibility is thus enhanced. When
the levels of input channels rise above a certain threshold, these will be automatically activated.
On the front panel, encoders with LED ring and peak value display for gain control in 1 dB increments, are used for selecting the input
sensitivity and priority. A Master encoder with two LED chains is used to adjust the output level, turning on output 1, 2, or both and to select
microphone or line level.

SUM VOLUME MASTER 1 + 2

Encoder for setting the total volume of the line outputs Master 1 and Master 2 (dual function). If the display LED 1 lights up green (N°26), the
sum volume of the line output Master 1 can be adjusted as desired using the MASTER rotary encoder. If the display LED 2 lights up green
(N°27), the same applies to the line output Master 2. Turning it to the right increases the volume and turning it to the left reduces it.

Select the line output Master 1 or Master 2 for volume setting by first pressing the push-button of the MASTER rotary encoder and then holding
it down for approximately 2 seconds. Now, while the LED display of the currently selected line output from Master 1 (N°26) or Master 2 (N°27)
flashes red, select the other line output for adjusting the total volume using the MASTER rotary encoder. Confirm the selection by pressing
the push-button on the MASTER rotary encoder. By combining the two output channels Master 1 and 2 in a channel group (see CHANNEL

STATUS-LED LINE

Displays the level status of the Master 1 and Master 2 line outputs. If the green status LED lights up, the output signal of the corresponding
line output Master 1 or Master 2 is output at line level (e.g. for the line input of a power amplifier). If the green status LED does not light up,
the output signal of the corresponding line output Master 1 or Master 2 is output with a 20 dB attenuation (e.g. for the microphone input of a
mixer). First select the line output for which the output level should be changed by pressing the MASTER rotary encoder and holding it down
for approximately 2 seconds, then select the line output (Master 1 or Master 2) with the rotary encoder (status LED flashes red) and confirm
your selection by pushing the push-button. Press and hold the press button of the MASTER rotary encoder for approximately 2 seconds and
turn the rotary encoder until the status LED LINE flashes red.

Now if you press the push-button of the MASTER rotary encoder again, the output is switched to the output level of either line or the

THRESHOLD

Input channels that have a signal level under a certain threshold level can be muted with this function. This means that the transmission
of a channel’s background noise, feedback or unwanted comb filter effects from other active channels are effectively suppressed and
intelligibility of speech is improved. Input channels that have a signal level over a certain threshold value are automatically activated. The
rotary encoder is deactivated for setting the threshold value during automatic operation (status LED no. 32 = green). The threshold value
is automatically adjusted to the volume of the surrounding sounds. The threshold value can also be set manually and individually for each
of the 8 channels. Set the threshold value in order that background noise does not automatically activate an input channel, but that the
activation of a channel speaker etc. is possible. Switch the THRESHOLD function to manual (see point 32 STATUS LED THRESHOLD AUTO
/ MANUAL) and briefly press the push-button of the desired channel (channel mute, 15-segment status LED flashes). Press and hold the
push-button until one of the status LEDs (“LINE” or “ACTIVE”) under the operating element of the corresponding channels flashes red, then
with the help of the THRESHOLD rotary encoder, set the threshold value between 0dB and -60dB as desired (please note the 15-segment
status LED THRESHOLD no. 30, all LED segments off = 0dB, all LED segments on = -60dB). Then briefly press the push-button of the
corresponding channel in order to confirm the setting and deactivate the muting. If there is no input for approximately 10 seconds, the
muting will be automatically deactivated and the currently set value remains the same.

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 MASTER

34

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 micro­phones 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.

DAISY-CHAINING

Up to 16 LD Systems AM8 automatic mixers can be daisy-chained to an audio system. When daisy-chaining the AM8 automatic mixers using
the LINK IN / LINK OUT interface on the rear panel of the unit, the device that must serve as the master unit needs to be configured as the
master unit. All other AM8 automatic mixers in the audio system will be configured as slave units (see point 33, CONNECTIONS, CONTROL AND
DISPLAY ELEMENTS). Connect the slave units to the master units unit using the supplied connection cable (slave unit LINK OUT -> Master unit
LINK IN, see figure). The audio inputs of all slave units of the AM8 automatic mixer in the system will be routed to the line outputs Master 1
and Master 2 of the master unit.

Install the AUTOMIX8 software on a Windows PC (Windows Vista, WIN 7, WIN 8, screen resolution min. 1366 X 768) and connect the AM8 automatic
mixer to the Ethernet interface of the computer using a LAN cable (CAT-5). Since the IP address of the AM8 automatic mixer is factory set to

192.168.1.88, the interface of the computer must be assigned a different IP address (see figure “Properties of Internet Protocol Version 4”). Start
the AUTOMIX8 software, then click with the left mouse button on “MENU”, now move the mouse pointer to “CONNECT” and confirm by clicking
with the left mouse button. Click the blue “SEARCH” field in the opening window.

If all settings and connections are properly made, the connected device is displayed after a few seconds with its IP address and an INFO
window announcing “Search finished” (search completed) appears. Press “OK”. To enter the user name (USER NAME) and password (USER
PSW), now click on the blue “OK” field. The factory preset password for the user “admin” and “user” is “000000” (six times the number zero).
Press “OK”.

If several AM8 automatic mixers are daisy-chained, and should settings and control be operated by the AUTOMIX8 software, an individual IP
address must be assigned to each individual automatic mixer. The mixers must be connected to the software one by one. While the IP address
is changed, the automatic mixer is restarted. After changing the IP address, you must restart the software and the device must be connected
again. Use an Ethernet switch to connect several automatic mixers to a computer.

THRESHOLD

Input channels with a signal level under a certain threshold value can be muted with the assistance of this function. This means that
the transmission of a channel’s background noise, feedback or unwanted comb filter effects from other active channels are effectively
suppressed and intelligibility of speech is improved. Input channels that have a signal level over a certain threshold value are automatically
activated. The rotary encoder is deactivated for setting the threshold value during automatic operation (“AUTO” button highlighted yellow).
The threshold value is automatically adjusted to the volume of the surrounding sounds. Manual setting of the threshold value (-60 dB to 0
dB) for automatic activation of the input channels is done separately for each channel (“CH SYNC” button greyed out) or for all channels
simultaneously (“CH SYNC” button highlighted yellow). If you click on “MAN” (“MAN” button highlighted yellow) and then select the desired
channel and threshold value in the drop-down menu, background noise will not automatically activate an input channel, but activation of a
channel by a speaker etc. is possible. Set the hold time of the activated channel by clicking on “HOLD TIME” in the drop-down menu and
then selecting the value of your choice (0 - 2000 ms). The channel remains active for the duration of the set hold time, even if the audio
signal falls silent. This means that a different channel can only become active after the end of the hold time.

EINFÜHRUNG

Der LD Systems AM 8 ist ein automatischer 8x2 Matrixmixer mit symmetrischen Mic-Line-Eingängen, 96kHz/24-Bit Signalbearbeitung und
einem Frequenzgang von 20 Hz – 30 kHz. Die Priority-Funktion des AM8 Automatik-Mixers kann für jeden Eingang individuell eingeschaltet
werden, der gesamte Schwellenwert zur Kanalaktivierung wird automatisch oder mit dem Threshold-Regler manuell gewählt.
Eingangs-Kanäle, deren Signal-Pegel unter einem bestimmten Schwellenwert liegen, werden mit Hilfe der Automix-Funktion stumm
geschaltet. Somit werden bei der Übertragung eines Kanals Nebengeräusche, Rückkopplungen und unerwünschte Kammfiltereffekte durch
weitere offene Kanäle wirkungsvoll unterdrückt und die Sprachverständlichkeit gesteigert. Eingangs-Kanäle, deren Signal-Pegel über einem
bestimmten Schwellenwert liegen, werden automatisch aktiviert.
Auf der Gerätefront dienen Encoder mit LED-Ring und Spitzenwertanzeige zur Gain-Regelung in 1-dB-Schritten, Wahl der
Eingangsempfindlichkeit und Vorrangschaltung. Ein Master-Encoder mit zwei LED-Ketten stellt die Ausgangslautstärke ein, aktiviert Ausgang
1, 2 oder beide und wählt Line- oder Mikrofonpegel.

THRESHOLD

Eingangskanäle, deren Signal-Pegel unter einem bestimmten Schwellenwert liegen, werden mit Hilfe dieser Funktion stumm geschaltet. Somit
werden bei der Übertragung eines Kanals Nebengeräusche, Rückkopplungen und unerwünschte Kammfiltereffekte durch weitere offene Kanäle
wirkungsvoll unterdrückt und die Sprachverständlichkeit gesteigert. Eingangs-Kanäle, deren Signal-Pegel über einem bestimmten
Schwellenwert liegen, werden automatisch aktiviert. Der Drehgeber ist für die Einstellung des Schwellenwerts während des automatischen
Betriebs deaktiviert Status-LED Nr. 32 = grün). Der Schwellenwert wird automatisch an die Lautstärke der Umgebungsgeräusche angepasst.
Die Einstellung des Schwellenwerts kann auch manuell und individuell für jeden der 8 Kanäle erfolgen. Stellen Sie den Schwellenwert so ein,
dass Umgebungsgeräusche einen Eingangskanal nicht automatisch aktivieren, aber die Aktivierung eines Kanals durch einen Sprecher etc.
ermöglicht wird. Schalten Sie die Funktion THRESHOLD auf manuell (siehe Punkt 32 STATUS-LED THRESHOLD AUTO / MANUAL) und drücken
kurz den Drucktaster des gewünschten Kanals (Kanal-Stummschaltung, 15-Segment LED-Anzeige blinkt). Drücken und halten Sie den
Drucktaster dann bis eine der Anzeige-LEDs “LINE oder “ACTIVE” unter dem Bedienelement des entsprechenden Kanals rot blinkt, um nun mit
Hilfe des Drehgebers TRESHOLD den Schwellenwert nach Wunsch von 0dB bis -60dB einzustellen (achten Sie auf die 15-Segment LED-Anzeige
THRESHOLD Nr. 30, alle LED-Segmente aus = 0dB, alle LED-Segmente an = -60dB). Drücken Sie wiederum den Drucktaster des
entsprechenden Kanals kurz, um die Einstellung zu bestätigen und die Stummschaltung zu deaktivieren. Erfolgt circa 10 Sekunden lang keine
Eingabe, wird die Stummschaltung automatisch deaktiviert und der aktuell eingestellte Wert bleibt erhalten.
