Configuration
To set the card’s ensemble channels, open
Control Panel
and double-click
on
Sounds and Multimedia
, click on the
Hardware
tab, select
Multi-
ensemble DAB+ Radcap
and click on
Properties
. In the Properties window
click on the
Configuration
tab and select the required channels from the
drop-down lists.
For each ensemble, if a signal is present, the ensemble RF spectrum,
RF signal level and phase reference correlator level are shown, with the
broadcast ensemble name appearing on the surrounding box.
Each channel must be set to a different ensemble.
Once the ensemble is set and the card is receiving a satisfactory signal,
the audio services on the ensemble will appear as Windows audio input
devices, using the names broadcast for the services.
The
Device Mapping
setting determines how the driver will behave when
services are added or removed from ensembles. If
Dynamic
is selected,
the corresponding audio devices will be added or removed, but if
Static
is
selected, the audio devices will remain unchanged until the next reboot
(although audio will be unavailable on any removed services).
The card is factory-configured for 1, 2, 3 or 4 ensembles. For an additional
charge, the number of ensembles can be increased in the field by applying
the appropriate expansion key. Contact Sonifex Ltd or your distributor and
quote the displayed
Hardware ID
number and your required number of
ensembles.
Recording
Any application that records from standard wave input devices can be used
to record the audio streams from the Multi-ensemble DAB+ Radcap.
Make sure the recording software you are using allows you to select the
audio input devices.
A recording level and mute control are provided for each service through
the devices’ mixer ports.
If recording a large number of channels using any form of audio
compression, be sure to allow sufficient processing power to both capture
the audio and compress it. The Performance Monitor in Windows’ Task
Manager provides a useful guide to CPU loading. Regrettably at this time,
