7.1 QUICK SETUP
Install the
DSPXtra-AM Encore
into the rack; The unit should be mounted in a grounded,
19” (483mm) equipment rack. While the DSPXtra-AM Encore generates little heat itself, it
could be damaged by being confined between other heat-generating equipment. If
the equipment directly below or above the DSPXtra-AM Encore runs hot, you should
allow one single rack space between them.
The area directly to the rear and sides of the unit should be open, to allow free-flowing
air, and the environment should be as dust-free as possible.
1.
Connect AC power to the unit;
2.
Connect the analogue or digital output;
3.
Select analogue or digital input as the source of processing with the ‘input’ item in
the ‘system|audio i/o’ menu;
4.
Navigate to the System | Audio i/o | Outputs menu, and adjust the low-pass filter
setting as required. This will affect the occupied bandwidth of the AM
transmission.
5.
You can use the built-in tone generator to set the output levels. Set the output
source in System | Audio i/o | Outputs to ‘tone’, set Amplitude to 60%, then adjust
the output level until your transmitter (or modulation monitor) reads 50%
modulation (the 10% difference is to account for possible overshoots in the
transmitter).
6.
Navigate to the System | Audio i/o | Inputs menu, and adjust the high-pass filter
setting.
7.
Navigate to ‘presets’, and select a preset from the list.
That’s it - You’re on the air!
Further information on each parameter is contained in section 9 ‘Presets Configuration’
in this manual.
7.1.1 AUDIO CONNECTIONS
The analog audio inputs and outputs are balanced XLR connectors (pin 2 +ve) and can
range from peak levels of -10dBu to +24dBu. The menus in the DSPXtra-AM Encore will be
used to calibrate the audio levels to suit your facility.
The digital inputs and outputs are AES/EBU compliant, and will also reliably handle S/PDIF
with suitable cable adaptors. A built-in sample rate converter will convert whatever the
incoming audio’s sample rate is to the preferred output rate, if desired. This selection is
made in the system|audio i/o menu.
