INTRODUCTION
The DS 1642 is a 16-channel Speaker Station
(19”/1RU) with for each channel a TALK and a
LISTEN button.
This unit has to be connected to mains power
(100 – 240 V AC, 50/60 Hz, 100 watts).
A channel is assigned to a user group as defined
by the system administrator in the configuration
software. Besides having conference
communication via the groups, the user may
initiate PTP (Person to Person) communication
(like a private telephone call) and send/receive
Text Messages (SMS).
The channel displays show for each channel the
listen level (volume bar), the group name and
“Audio Detect”. The master display shows the
assignments of the function buttons, the menu
items and the text messages.

The master section has programmable function
buttons, a MIC ON button, a SOLO button and a
PTP button.
The alpha-numerical keypad allows to enter ID
numbers and user names. The MENU button is
used to enter or exit the Menu.
Connecting the DS 1642 speaker station to an
intercom line ('string'), one uses the 'Intercom In'
connector. The 'Intercom Link Out' connector is
used in case of a daisy chain wiring topology.
A headset may be connected to the XLR-4
connector on the front panel. A binaural DS 1642
has an XLR-5 connector for left-centre-right use
of the headset cans. Limiters for the headsetand gooseneck microphone prevent the mic
signal path from clipping. A proprietary frequency
correction provides high intelligibility.

FRONT PANEL CONTROLS & CONNECTORS
1
Channel Displays
Show for each channel the listen level (volume
bar), Audio Detect” and the assigned group
2
Master Display
Shows the functions assigned to the function
buttons, the menu functions (after entering the
menu), the PTP functions (during PTP mode) and
user ID number (during login procedure).
3
TALK buttons
One for each channel, latching or momentary.
Latching:
If a TALK button is pushed shortly it latches and
the mic signal is sent to the corresponding
channel . If pushed again the button switches off.
The latching function can be disabled by the
system administrator in ConfigurIT™.
Momentary:
If a TALK button is pushed for at least 2 seconds,
the microphone signal is sent to the
corresponding channel until the button is
released.
If a TALK button is switched on, it is lit green
provided the MIC On button was activated.
If a TALK button is switched on but not the MIC
ON button, the TALK button is lit yellow.
4
LISTEN buttons
To enable the listen function of each channel.
If enabled, the buttons are lit green. The listen
level of each channel is shown in the channel
display by a volume bar. The level may be
adjusted by turning the Volume encoder whilst
keeping the equivalent listen button pushed.

5
GOOSENECK jack connector
To hold a the gooseneck microphone which may
be of the electret or dynamic type.
The mic signal path for either mic type has to be
adjusted by the user, via menu item #9
'GOOSENECK MIC TYPE' or by the system
administrator in the configuration software.
6
HEADSET connector (XLR-4)
To connect a headset. The DS 1642 speaker
station accepts headsets with microphones of the
dynamic or electret type. The mic signal path for
either type has to be adjusted by the user, via
menu item #7 'HEADSET MIC TYPE' or by the
system administrator in the configuration
software.
If a headset is plugged in, the gooseneck mic and
the loudspeaker are automatically disabled.
The speaker can be enabled again by pushing
the SPKR On/Off Function Button. Both the
headset can(s) and the speaker are now on.
10
VOLUME knob
By turning this rotary encoder the volume of the
intercom and PGM audio signals are controlled,
for both loudspeaker and headset.
By pushing and turning the rotary encoder, the
volume of the PGM signals (see #19) may be
adjusted in the required balance with the intercom
signals. In that case the rotary encoder is the
MASTER volume control for intercom and the
PGM signals. However, the encoder may be
programmed to adjust the Intercom volume and
the PGM volume independently (see menu item
#24 ‘Master Volume’)
The rotary encoder is also used:
• to adjust the listen level of a channel by
turning the volume encoder whilst keeping
the LISTEN button of that channel pushed
• to scroll through the Menu and PTP items.
• to adjust the PTP listen level when being
on a PTP call.
7
LOUDSPEAKER
To hear the intercom and PTP communication as
well as the PGM signals and the Error, Ring, and
Engaged tones.
11
PTP button
To initiate a PTP (Person to Person) call or
‘taking’ an incoming PTP call (see description of
PTP communication). The button is also used in
Text Messaging (SMS) procedures.
8
SOLO button
To activate the SOLO mode of the station. If a
TALK button of a channel is pushed whilst the
unit is in SOLO mode, the user talks and listens
to the selected channel only. The TALK button is
now momentary only and the equivalent LISTEN
button switches on automatically. All TALK and
LISTEN functions of the remaining channels are
disabled and the MIC ON button switches on
automatically (if it was switched off before).
12
FUNCTION buttons (F1, F2, F3, F4)
To these function buttons a various functions may
be assigned. By pushing the SHIFT button in the
keypad, four other functions may be assigned to
these buttons. Assigned functions are shown in
the master display, below each of the function
buttons.
To activate a function the corresponding function
button is pushed. The functions are listed in the
ASL Digital user manual..
9
MIC ON button
If switched on, the MIC ON button is lit yellow if
none of the TALK buttons are activated.
If the MIC ON button is switched on and one or
several TALK buttons are activated, the MIC ON
button is lit green and the mic signal is sent to the
selected channels. TALK buttons which are
pushed whilst the MIC ON is switched off are lit
yellow, indicating no signal is sent to the selected
channels.
13
Keypad
This alpha-numerical keypad is to enter ID
numbers and names and includes a MENU button
and a SHIFT button. The MENU button is to enter
the Menu (keep the button pushed for 2 seconds)
or to exit the Menu and to confirm the ID number
when logging in. With the SHIFT button the
speaker station can be put in Standby Mode
(keep this button pushed for 4 seconds)

MISCELLANEOUS
Side Tone:
Using a headset, ones own voice is heard in the
headset cans. This is called 'Side Tone', which
may be adjusted by the user via menu item #6
‘SIDE TONE HEADSET’ or by the system
administrator in the configuration software.
Amplifiers for headset:
The output amplifiers have a current limiter.
The bridged amplifiers are optimized for 200 ohm
(2 headset cans parallel, each 400 ohm). Lower
and higher impedances are supported but
performance may decrease.
Amplifier for loudspeaker:
The output amplifier has a current limiter, set to
max 1,25A.
Speaker Attenuator :
If the gooseneck microphone is switched on, the
output of the loudspeaker is attenuated. This to
avoid the signal from the speaker enters the
microphone (feedback). The degree of
attenuation may be adjusted by the user via menu
item #25 ‘Speaker Attenuator’ or by the system
administrator in the Configuration software.
Mic Input Circuitry:
A built-in limiter preserves the mic signal path
from clipping. A presence filter (proprietary
frequency correction) provides high intelligibility.
This filter may be switched on or off, by the user
via menu item #12 'PRESENCE FILTER' or by
the system administrator in the configuration
software
For each type of gooseneck or headset
microphone there is a default gain setting.
These default settings may be adjusted with
-4 dB to +20 dB, by the user via menu item #8
‘HEADSET MIC GAIN’ and menu item #10
‘GOOSENECK MIC GAIN’ or by the system
administrator in the configuration software.
