Introduction
1.1 TX5 FM TRANSMITTER
The BW Broadcast TX5 is a high specification FM broadcast transmitter. Its broadband "no-tune" design allows
87.5-108 MHz operation from internal direct reading rotary switches or the front panel LCD frequency control sys-
tem if enabled. Digital PWM techniques provide an easily adjustable and accurate automatic level controlled R.F.
output of the MOS-FET power amplifier stage. With integrated multi-band DSP technology the TX150/300 ideal for
creating a loud, punchy, on-air presence.
A metering system offering accuracy normally found on specialist test equipment is available at a glance on the
LCD graphics display. Partnered with the simple controls and clear menus a new level of ease of setup and instal-
lation is achieved. Local and remote personal computer control and metering are achievable via RS232 interface
and there's an alarm I/O and trigger I/O connectors for full system flexibility.
The four band digital signal processor features automatic gain control, multiband leveling, and distortion cancel-
ling clippers to limit audio level; keeping your signal to a maximum in both level and quality.
The FM modulator section employs a dual speed "virtual VFO" system for extremely low audio distortion and
excellent stereo performance. A built in high specification stereo encoder provides crystal clear stereo sound and
combined with the internal limiter a fully compliant "plug and play" all in one low power broadcast transmitter.
For future compatibility all settings are switchable with on board jumpers and dip switches. The stereo and pro-
cessing settings can be switched in and out to suit the requirements of any external broadcast equipment you
may have now and in the future.
The lightweight mains input design ensures a high reliability efficient design compatible with any mains system in
the world.
