3.1.6 Channel Knob (dual purpose)
3.1.6.1 Volume Channel A/B
The channel volume knob levels the channel volume of the WB-2 (0-100%). Turn the knob clockwise to increase and
counterclockwise to decrease the volume of the channel.
3.1.6.2 TALK Channel A/B (Auto / Momentary)
Pressing the left knob activates the TALK for channel A. This is indicated by the green Channel A LED.
Pressing the right knob activates the TALK for channel B. This is indicated by the green Channel B LED.

momentary mode by the DIP switch #1 for channel A and DIP switch #2 for channel B at the bottom side of the WB-2.
Page 12

User Manual Acrobat V3.30 Rev1.0
3.1.7 CALL Key
When TALK A or TALK B is active, pressing the CALL key
•sends a CALL signal to the related channel (A, B or A and B) of the partyline and
•activates the CALL LED until the CALL Key is released.
On all connected devices, the corresponding CALL signal will light up e.g. WB-2 - TALK LED (green) alternates blinking with the
CALL LED (orange).
The CALL Key is also sent to the external user via the GPO interface.
3.1.8 SCALL Key
If TALK A or TALK B is active, pressing the SCALL key sends a command to close the GPI-out to the devices on the
corresponding channel. The GPI signal can also be understood by an Artist/Performer system, if connected.
The function carried out by the SCALL key is not displayed on the WB-2.
3.1.9 Battery
The light and powerful rechargeable Lithium-Ion battery Acrobat RB-2300 allows the Acrobat Digital Wireless Beltpack 8 hours
of operation.
The battery is located in the covered battery case at the right side of the WB-2.

SW OFF ON Comment
1 Latched/Auto Momentary Switches between momentary and latched for TALK A. In OFF
position a short press on the TALK A knob routes the
microphone signal to Channel A. Another short press turns it off
(Latched). If the knob is pressed and held for longer than 0.25
seconds it functions as momentary and the channel is closed as
soon and the knob is released (Auto). When the DIP switch is in
the ON position the channel is only open as long as the knob
remains pressed (Momentary).

Adjustment
In ON position the alert tone can be adjusted up or down using
the Channel A knob. The CALL LED will blink to indicate that the
DIP switch is ON. After the side tone has been adjusted, SW-7
must be returned to the OFF position. If the value has changed,
the WB-2 undergoes a restart procedure.
8 OFF Side Tone
Adjustment
In ON position the side tone can be adjusted up or down using
the Channel A knob. The CALL LED will blink to indicate that the
DIP switch is ON. After the side tone has been adjusted, SW-8
must be returned to the OFF position! If the value has changed,
the WB-2 undergoes a restart procedure.

4Service menu
Besides the normal operation mode of the WB-2, a special service mode consisting of a service menu is available.
If the WB-2 is in service mode, the following restrictions apply:
•The display of the operation mode is not available, instead the service menu will be displayed.
•The TALK functionality of both Channels is not available
•After leaving the service mode with changes made, the WB-2 will undergone a reboot to activate the changes.
Overview of available functionalities in both modes.
Feature Operation Mode Service Mode
Listen to partyline Yes Yes
Incoming CALL Yes Yes
Outgoing CALL Yes No
TALK to partyline Yes No
4.1 Activation of service menu
4.1.1 Prerequisites
The activation of the service menu is NOT possible if a Channel is active. To use the service menu, all Channels
have to be closed using the Channel Knobs A and/or B.
4.1.2 Open service menu
Pressing the CALL Key and the SCALL key simultaneously (or consecutively while keeping the other pressed) will open the
main menu of the service menu.
If a TALK channel (A and/or B) is active accidentally, this procedure will initiate a CALL signal and a SCALL signal
to the corresponding channels.
