Processing Preset
BW Broadcast’s range of award winning DSPX audio processors has become known for their
features, 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 which
one is more suitable for your program material. Each processing preset is loaded live as the
user 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 and
limiters, 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 connected
to 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 option
for bypassing the internal audio processor is to use the external MPX input. In this case, the
MPX Source parameter must be set to External.

Pre-emphasis
This 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 or
digital inputs and select Bypass as the Processing Preset.
Make sure Pre-emphasis is Off when using an external processor connected to the analog or
digital inputs and select Bypass as the Processing Preset.

Triggers
Figure 9.1: Alarms and Triggers Port
V2 Transmitters have a comprehensive monitoring
and 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 to
control the unit through a telemetry interface system.
Trigger pins are designed to work with relay contacts
to 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 on
the rear alarms and triggers connector. To fire a trig-
ger, the pin must be pulled low.
