1The TX-V2The 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 orcalibration. 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 provenultra-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 (onmost models) make in-field maintenance simple.A high resolution OLED screen displays RF, audio and system parameters. The control wheeland 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. TheLAN 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 beused.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 wholike 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.9

Part IIInitial Setup and connections25
7Installation7.1 Quick StartN.B. Never power on an FM transmitter without a suitable antenna or dummy load connected.The V2 Transmitter’s protection circuitry will prevent any internal damage, but it is not advis-able to run an FM transmitter without a load connected.Setting up a V2 Transmitter couldn’t be any easier. First connect either analogue audio tothe left and right back panel connectors (10 and 11), digital audio AES/EBU into the left handconnector (10) or feed the MPX input (13) from an audio processor. Connect the RF output(18) to a 50Ohm antenna of the correct power handling capability. Connect the requiredremote control / monitoring ports (Ethernet, RS232, Alarms/Triggers Port).The transmitter’s frequency and power are both set from the RF Settings menu:Input selection, pre-emphasis, processing and the stereo parameters are set in the audio set-tings menu:Input Selects analog or digital input to the transmitter’s built in stereo encoder/audio proces-sor. For analog, connect to left and right XLR Inputs. For digital, connect an AES/EBU connec-tion to the left hand XLR input.Pre emphasis Sets pre emphasis to off, 50µS (Europe/Japan) or 75µs (Americas).Processing Preset Selects the processing preset on the integrated 4-band DSPX audio proces-sor.26
Encoder Selects the stereo generator mode, from either: Stereo, Mono L+R, Mono L, Mono Rand Swap L + R.MPX Source Selects if the MPX source for the exciter is internal or external. If using the V2 trans-mitter with no external equipment (RDS, audio processor etc) then set to internal. If using anyexternal equipment set to external. When set to internal, the MPX In and MPX Out connectorsare internally connected. which routes the internal stereo generator directly to the exciter.When set to external, the internal the internal stereo generator and audio processor are stillfunctioning, but the MPX in and MPX out connections are not internally connected, allowingMPX signals to be routed to and/or from external equipment.7.2 Examples of Use7.2.1 Transmitter with an external RDS encoder and internal audio processing1. Place the transmitter in a well ventilated space.2. Connect the antenna to the RF output connector on the back of the transmitter.3.

Once the transmitter is operating, set the correct carrier frequency and power from theRF settings menu. Check reflected power is OK.9. In the RF settings menu, set MPX source to external.10. Check the modulation level - if the modulation level is low, adjust the MPX output levelon your audio processor (or stereo generator) and/or the MPX input level on the backof the transmitter. The maximum modulation should not exceed 75kHz.11. Check the documentation that came with your audio processor on how to set/checkthe proper pilot injection level.12. Check the documentation that came with your RDS encoder on how to set/check theproper RDS injection level.In this setup, the audio stereo multiplex is generated in the audio processor. The RDS data isfed into the audio processor where it is combined with the audio multiplex. This combinedsignal is fed directly into the transmitter exciter. Note that the transmitter’s onboard process-ing will have no effect on the signal in this configuration. This is the best connection in termsof pilot and RDS subcarrier phase synchronization and MPX spectrum cleanliness.31

9Parameter Guide9.1 RF Settings9.1.1 FrequencyThis sets the transmission frequency. The range for this parameter depends on the Band. Fornormal Band II transmitters the range is 87.5 MHz to 108 MHz. The normal step size is 50 kHz.Other frequency ranges and step sizes are also available on request. Please contact a salesrepresentative for more information.9.1.2 PowerThis sets the RF output level in watts. The range and the step size for this parameter dependon the model of the transmitter. The following table lists all the ranges for the different modelsin Watts:Transmitter Model Minimum Power Maximum Power Step SizeTX5 0.05 5.05 0.05TX50 5.4 50.4 0.45TX300 30.8 310.8 2.8TX600 60.5 610.5 5.5TX1000 152 1102 9.5TX1500 162 1512 13.5Note that when setting the power, the unit will automatically adjust the power output toreach the selected value. This may take a few seconds. During this time, the FWD power indi-cator in the Status Box will flash to indicate that the unit is still adjusting to reach the selectedpower.9.1.3 MPX SourceThis selects the source for the exciter. Options are Internal or External.Internal selects the in-ternal generator, i.e. the output from the internal audio processor. This option must be se-lected when the digital or analog inputs are used. External selects the MPX BNC input. Thisoption must be selected when the transmitter is used with an external audio processor con-nected to the MPX BNC input.62
9.1.4 FSK (for translators in the USA)V2 Transmitters support automatic station identification using frequency shift keying (FSK). FSKsends a user defined ID once every hour using Morse code and shifting the carrier frequencyup by 12.5kHz at 20 words per minute.FSK IDIf enabled, the FSK ID will be sent once every hour. The required station ID must be entered inFSK ID (up to 16 characters).9.1.5 RF Mute on SilenceThis selects the time after which the transmitter’s RF output will be muted if the transmitter istransmitting silence. Options are: off, 1 min, 10 min, 30 min and 1h. The transmitter identifiessilence as a signal that produces a deviation of less than 30 kHz for the time period selected.The Status box will indicate that the output of the transmitter is muted:9.1.6 RF Mute (Manual)This will manually mute the transmitter. The Status box will indicate that the output of the trans-mitter is muted as shown in the picture above.9.1.7 Power SchedulerThis feature allows the unit to be configured for transmitting different RF power levels at dif-ferent times of the day. The unit will normally transmit the signal at the power specified in RFSettings ⇒Power. If the power scheduler is disabled, the unit will keep transmitting at thispower level all of the time. If the Power Scheduler is enabled, the unit will switch to the se-lected scheduled power (Power Scheduler ⇒Power) when the time matches the Start Timeand will return to normal power when the time matches Finish Time.This feature is intended to allow users to lower the power of their transmission at night time toreduce power consumption and avoid increasing the range of the transmission due to thechange in atmospheric conditions. Please adhere to your licensing restrictions on power.63
EnableEnables/disables Power Scheduling.PowerSelects the power that the transmitter will produce during the scheduled interval.Start TimeSelects the time at which the output power will change from normal power to scheduledpower.Finish TimeSelects the time at which the output power will change from scheduled power to normalpower.Current TimeCurrent time set in the unit. It can be modified to adjust the time in the Real Time Clock.9.2 Audio Settings9.2.1 MPX SourceThis is the same parameter as described in RF Settings. It has been placed in the Audio set-tings menu for convenience of access. This selects the source for the exciter. Options areInternal or External.Internal selects the internal generator, i.e. the output from the internalaudio processor. This option must be selected when the digital or analog inputs are used. Ex-ternal selects the MPX BNC input. This option must be selected when the transmitter is usedwith an external audio processor connected to its MPX BNC input.9.2.2 Audio InputSelects Digital or Analog as the audio input. These are the XLR connectors in the back panel.Note that the MPX Source parameter must be set to Internal to use the analog or digital in-puts.64
9.2.3 Processing PresetBW Broadcast’s range of award winning DSPX audio processors has become known for theirfeatures, performance and value for money. Integrated within all V2 Transmitters is the 4-band DSPXmini FM SE. This parameter selects the audio processing preset that the internal au-dio processor will use. Options are: Bypass,AC,CHR,Tight,Hot,Loud,Smooth,Clean,Bright,RockNRoll,Low Bass,Urban,Talk,Classic Bright,Classic Bright2. Each processing preset pro-vides a different overall sound. Try and experiment with different presets to find out whichone is more suitable for your program material. Each processing preset is loaded live as theuser scrolls through the menu allowing for easy comparison between them. A dedicated me-tering screen (Audio Status) indicates the input levels, 4 band automatic gain control andlimiters, along with audio level and MPX level meters. The Bypass preset can be used to by-pass the internal processing. This is useful when using an external audio processor connectedto the digital/analog inputs. In this case, an 8dBu signal on the back panel analogue input(or -18DBFS on AES inputs) should be used to align to the safety clipper thresholds of the inter-nal processor. Make sure Pre-emphasis is off when using the Bypass preset. Another optionfor bypassing the internal audio processor is to use the external MPX input. In this case, theMPX Source parameter must be set to External.9.2.4 Pre-emphasisThis parameter allows you to select the desired preemphasis characteristic (off,50us or 75us).Make sure Pre-emphasis is Off when using an external processor connected to the analog ordigital inputs and select Bypass as the Processing Preset.9.3 TriggersFigure 9.1: Alarms and Triggers PortV2 Transmitters have a comprehensive monitoringand control system consisting of 3 alarms and 4 trig-gers. Pin 2 of the connector is hardwired to RF mute.Connecting this pin to ground will mute the transmit-ter. The alarms and triggers port can also be used tocontrol the unit through a telemetry interface system.Trigger pins are designed to work with relay contactsto ground or 5 V drivers able to sink 15 mA (per trig-ger pin). Triggers are used to control certain param-eters on the V2 Transmitter using the relevant pins onthe rear alarms and triggers connector. To fire a trig-ger, the pin must be pulled low.9.3.1 EnableEnables/disables the trigger.65
9.3.2 ActionSelects what the trigger will do when it is detected. Options are: Frequency Up,FrequencyDown,Power Up,Power Down,RF Mute,Switch to Int MPX,Switch to Ext MPX,Switch to Mono,Switch to Stereo,Reboot.Frequency Up,Frequency Down,Power Up,Power Down and Re-boot will perform the action on falling edges of the signal at the trigger pin. RF Mute actsbased on voltage levels. RF Mute will be engaged for as long as the trigger signal is pulledlow and unmute when the signal is high.Note that the RFMute pin (Pin 2) mutes the unit unconditionally. (Triggers set to RFMute willnot be able to unmute the unit if this pin is connected to ground).9.3.3 Send e-mailSelects if an e-mail will be sent when the trigger is fired. Make sure that the unit is connectedto the network and that E-mails have been set up correctly System ⇒E-Mail to use this fea-ture.9.3.4 (ON) MessageSets the message that will be sent when the Trigger changes to ON. This parameter acceptstext up to 300 characters.Sample e-mail:”Trigger 1 transitioned to ON.Equipment: TX-V2, Serial Number #8790Location:Local IP Address: 192.168.5.31If you require off-air emergency technical support, please contact the BW Broadcast 24/7support team:International Phone: +44 208 2530295US Toll Free: 1-888-233-1663Email: support@bwbroadcast.comPlease note that this is an automatic email alert generated by a BW Broadcast TX-V2. To pre-vent further emails please clear the cause of the alarm or turn off alarm emails on the TX-V2’scontrol system.”66
9.4 AlarmsFigure 9.2: Alarms and Triggers PortAlarms on the V2 Transmitter are used to indicate thata failure condition is met. They can be set to triggeron Modulation level, Forward power, Reverse powerand PLL lock fail. Upon triggering they will toggle therelevant pin on the rear alarms and trigger connec-tor. They will also write a notification to the RS232,write to the system log and send an e-mail if required.Alarm pins can be configured as open-collector Out-puts (when working as alarms) or as Analogue out-puts (for reporting system parameters as analoguevoltages). When used as alarms (open-collector out-puts), 10 kOhm external pull-up resistors to 12 V shouldbe placed on each pin to be able observe voltagechanges in the alarm pins.9.4.1 TypeAlarms can be configured as either alarms (open collector pins that will show ’0’ volts or opencollector depending on the result of the condition tested); or as analogue outputs, which willreport a parameter as an analogue voltage. The parameter Type allows this selection by pro-viding the options Alarm and Analogue Out.Alarms pins as AlarmsATypeWhen the alarm Type is set to be Alarm, the system will look at the specified failure con-dition in the Source parameter and trigger the alarm if the condition has been presentfor longer than the specified On Delay time or release the alarm if the condition has notbeen present for longer than the specified Off Delay time.BSourceSelects the failure condition that alarm will watch for. Options are: Mod Level <,ModLevel >,Fwd Power <,Fwd Power >,Rev Power <,Rev Power > and PLL Lock Fail.-Mod Level observes conditions in the modulation (or deviation) level of the transmittedsignal.-Fwd power observes conditions in the Forward power-Rev power observes conditions in the Reverse power-PLL Lock Fail observes if the PLL lock has failed and the system cannot tune to the re-quired frequency.67
CThresholdSelects the threshold value that will be used to detect the error condition. This doesn’tapply to the PLL Lock Fail alarm.DPin PolaritySelects whether the alarm output pin is active high or active low. When +ve is selected,the output will act as a 430 Ohm resistor to ground when the alarm is active and as a 100KOhm resistor to ground when the alarm is not active and vice-versa if -ve is selected.EOn DelaySelects how long the failure condition must be present for before the alarm is fired. Thiscan be set from 2 seconds to 600 seconds.FOff DelaySelects how long the failure condition must have stopped for before the alarm is re-leased. This can be set from 2 seconds to 600 seconds.GSend e-mailSelects if an e-mail will be sent when the alarm state changes. Ensure that the unit isconnected to the network and that E-mails have been set up correctly System ⇒E-Mail to use this feature.Examples of alarm uses and set-upExample 1: We would like the system to fire alarm A with normal polarity when the forwardpower has dropped below 40.5 watts for longer than 20 seconds. We would like the alarm tobe release if the power rises above 40.5 watts for longer than 10 seconds.Setup:1. Navigate to Alarms ⇒Alarm A2. Select Type =Alarm3. Select Source =Fwd Power <4. Set Fwd Power Threshold to 40.5W5. Set Pin Polarity to +ve6. Set On Delay to 20s7. Set Off Delay to 10s8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-abled (consult the relevant section in this manual)68
Example 2: We would like the system to fire alarm B with inverted polarity when the modula-tion level has dropped below 30 kHz for longer than 15 seconds and release alarm B when themodulation level rises above that level for 5 seconds. This is a way of detecting that silencebeing transmitted.Setup:1. Navigate to Alarms ⇒Alarm B2. Select Type =Alarm3. Select Source =Mod Level <4. Set Modulation Threshold to 30kHz5. Set Pin Polarity to -ve6. Set On Delay to 15s7. Set Off Delay to 5s8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-abled (consult the relevant section in this manual)Example 3: We would like the system to fire alarm C with normal polarity when the reversepower increases above 10.35 watts for longer than 20 seconds. We would like the alarm tobe release if the reverse power decreases below 10.35 watts for longer than 10 seconds.Setup:1. Navigate to Alarms ⇒Alarm C2. Select Type =Alarm3. Select Source =Rev Power >4. Set Fwd Power Threshold to 10.35W5. Set Pin Polarity to +ve6. Set On Delay to 20s7. Set Off Delay to 10s8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-abled (consult the relevant section in this manual)69
Alarms pins as Analogue OutputsWhen the alarm Type is set to be Analog Out, the alarm pin will report the status parameterselected in Source as an analogue voltage on the alarms pins. This setup is typically usedto connect the unit to remote control equipment (also known as telemetry interfaces). TheSouce can be set to any of the following parameters: Fwd Power,Rev Power,PA Volts,AuxVolts,Peak Modulation,PA Temp,RF Mute.Use the following equation to translate voltage levels into parameter values:CurrentValue =VOut ∗1.2 ∗NominalValue5(9.1)Where:VOut is the voltage on the pin in Volts.NominalValue is defined in the following table:Parameter NominalValueFWD PowerFor TX50 = 50WattsFor TX300 = 300 Watts...REV Power Same as FWD PowerPA VoltsFor TX5 = 15 VoltsFor TX25 and TX50 = 24 VoltsFor TX300 or greater = 48VoltsAux Volts 15 VoltsPeak Mod 100 kHzPA Temp 100°C*RF Mute* This parameter does not use the above equation.Its representation is:If RF Mute = On, VOut = 5 VoltsIf RF Mute = Off, VOut = 0 VoltsFor example, if the measured Voltage level is 4.166 Volts on a TX50 reporting Forward Power,the actual current value will be:Power (watts)= (4.166*1.2*50)/5 = 49.992 Watts (Approx. 50 Watts)9.5 System9.5.1 DateSystem Date.

Modulation level is too low•Most professional signal sources will be able to drive BW Broadcast transmitters to full de-viation. Some battery-powered or weaker sources, such as PC sound cards, may not beable to provide enough drive to achieve full modulation in the transmitter. If using theXLR inputs and the internal audio processor then we advise that you check the metersscreen in the Front Panel (Please press the bottom button on the right until meters screenappears). Assuming that the transmitter preset is not set to Bypass, then you should beable to observe movement on the meters labeled ”LIM” and ”AGC”. If you they do notmove, then you should increase the level in your audio source so that they do.If you are not able to increase your audio level from your external audio source you canincrease it by adjusting the level pot located on the left hand side of the 2 BNCs on therear panel.I am using the MPX input and have strange sound issues•Ensure that Audio Settings ⇒MPX Source is set to External.•Leaving it switched to Internal will feed the internal stereo generator audio into the ex-citer. This will result in distortion and interference with the signal you are feeding fromyour external composite source connected to the MPX input of the transmitter.Transmitter occasionally changes RF power•Please check tat the Power Scheduler feature is not enabled (RF Settings ⇒PowerScheduler). If this feature is required, ensure it is correctly set-up and the time in the sys-tem is correct. Please refer to Operation Guide ⇒RF Settings ⇒Power Scheduler onthis manual to properly configure this feature.Temp fault light is on•Please ensure that the fans are running and not obstructed and the transmitter is in awell ventilated area.Other IssuesIf your issue is not covered in this guide or you have tried the above and still having trouble,you can contact our 24 Hour Support Team:International Phone: +44 208 253 0295US Toll Free: +1-888-233-1663Email: support@bwbroadcast.com80
