The TX-V2
The BW Broadcast TX-V2 is the latest development in a high specification range of FM trans-
mitters over 15 years in the making.
Its broadband ”no-tune” design allows 87.5 - 108MHz operation without requiring tuning or
calibration. The inclusion of four-band DSPX audio processing means stations without a ded-
icated processor sound great, right out of the box. Those who already have external pro-
cessing benefit from BW Broadcast’s unique dual-loop virtual VFO exciter and field proven
ultra-low distortion modulator integrated into a great performing, highly stable FM transmis-
sion system.
Features such as slide-in power supplies, and unique solder-free Gold-Clamp transistors (on
most models) make in-field maintenance simple.
A high resolution OLED screen displays RF, audio and system parameters. The control wheel
and three front panel buttons allow easy navigation of the menus. Help tips for every param-
eter make setup simple.
Every TX-V2 Transmitter features a LAN connection for Ethernet local or remote control. The
LAN connection also supports SNMP, telnet, and email alerts via either SMTP or BW Broad-
cast’s mail server. Where a LAN connection is not available, the RS232 connection can be
used.
Intelligent alarms and email alerts ensure busy engineers can manage their stations with min-
imal intervention. A real time clock and comprehensive logging is available for those who
like to see more detailed status. Also present are 4 rear panel opto-isolated triggers that al-
low external equipment to control the transmitter.
It is advised that this manual is read to learn all of the advanced features of the TX-V2 Trans-
mitter.
