1User Information
1.1 General Features
The R&S®GB4000V provides audio, PTT and squelch to and from radios in a remote
location. The unit is compact and fits into any console. The R&S®GB4000V can be
connected to the radios using 4-wire E & M (analog line) or voice over IP (VoIP). When
connected using an analog line, either 4-wire E & M lines (PTT, SQ) or in-band tones
for E & M can be used. The available tones are 2040 Hz (PTT) and 2440 Hz (SQ). In-
band signaling is handled by the R&S®GB4000V, thus eliminating the need for other
external devices.
When used with the R&S®GB4000T touchscreen control unit, the R&S®GB4000V can
be connected to any of up to nine channels using R&S®Series4200 radios via VoIP.

EUROCAE ED137-1 compliant VoIP connection to the R&S®Series 4200,
R&S®Series4400 and R&S®Series4100 radios
Built-In loudspeaker with the volume control
Configurable minimum volume setting to ensure safety
LEDs indicate the status of the radios (PTT, SQ, VoIP)
Available with an additional headset connector for instructor operation
External loudspeaker connection for monitoring
Can be mounted in a 19" rack or in operator consoles
Two independent DC connections for redundant power supply
Easily configurable via a web browser

R&S GB4000V Audio Unit
User Manual 6174.7514.02 - 02 15
If the unit is exposed to climate fluctuations, condensation may occur.
Precipitation of humidity (condensation) on and within the unit may be the cause of
damage or even destruction.
After storage or transport in cold weather or if extreme variations in temperature occur,
the R&S GB4000V must be slowly adapted to the ambient temperature of the
installation site.
With condensation, allow at least 12 hours of temperature adjustment before starting
up.
For storage observe the environmental data specified in chapter “1.5”.
2.3 Installation
The sequence of installation and cabling depends on the installation site (panel, rack)
and the accessibility of the interfaces when the unit is installed.
For dimensions of the R&S GB4000V refer to the Installation Drawing in
“Appendix”.
Preparation for installation into a control panel
►Prepare the control panel to accommodate the R&S GB4000V. For dimensions of
the panel cutout refer to “Figure 3”and “Figure 4”.

1. Insert the R&S GB4000V into the control panel or rack at its designated position.
2. Secure the unit by means of four screws passed through the bore holes in the
corners of the front panel.
The unit is to be mounted according to IEC 60297 (VAR02/03).
Figure 5: Bore holes for fixture of the R&S GB4000V.
When installing the unit ensure that existing sealing profiles are not damaged.
To prevent overheating damages make sure the ventilation holes on both sides of the
audio unit are not covered.
Make sure the environmental conditions specified in “1.5” are complied with.

R&S GB4000V Audio Unit
User Manual 6174.7514.02 - 02 18
Avoid strong magnetic fields which can have influence on the audio signals.
Avoid strong interfering voltage on the supply lines. This interfering voltage can have
influence on the audio signals.
2.4 Cabling
Read the relevant documentation for the equipment before attaching external devices.
Always take hold of the plug when pulling or connecting cables. Do not pull on the
cables. All connections and cables must have a sufficient electric and voltage strength.
It is recommended to use shielded cables.
Danger of burns on the rear panel. The rear of the unit becomes hot. Do not directly
touch the body during or soon after an operation.
