PTRL NV/3 & RXRL NV/3
5.4 Modes of Operation
5.4.1 Mono transmission from mono audio source on main mono channel
1)
Connect the RIGHT input connector of the radio link transmitter to the
corresponding audio signal as described in section "system connection". Connection
to the LEFT channel input is not necessary. The signal runs through the channel
processor, is filtered at 15 kHz and preemphasized.
2)
Select "MONO R" mode in the setup menu (see relevant section in this manual).
Confirm preemphasis or choose the 50 or 75 µs setting as required.
5.4.2 Mono transmission from stereo audio source through internal coder
(option)
1)
Connect the RIGHT and LEFT input connectors of the radio link transmitter to
their audio signals as described above. Applied audio signals run through the
incorporated channel processor, are filtered at 15 kHz and preemphasized in both
channels. The incorporated stereo coder will mix the stereo input signal to provide
mono transmission. The transmitter is set up for stereo transmission, in the event it is
necessary. All you need to do is select "STEREO" transmission mode in the "MODE"
menu mentioned above.
2)
Select "MONO L+R" mode in the setup menu. Confirm preemphasis or choose
the 50 or 75 µs setting as required.
Note: The incorporated coder lets you choose if you want the sum of left and right
channel, the left channel only or the right channel only sent in mono transmission. This
option is set using the internal jumpers on the BD1 selector on the coder board (see
stereo coder description in the service section of this manual). Factory setting is
mixed left and right channels.
5.4.3 Mono or stereo transmission from external coder or other radio link
receiver
1)
This is a preemphasized "Multiplex" signal (MPX). Use the "MPX" input of the
radio link transmitter. The signal will skip the filtering and stereo coding stages and
requires no additional preemphasis.
2)
Select "EXT MPX" mode from the setup menu. We recommend selecting the
appropriate preemphasis as required (50 µs for Italy); this setting takes no effect in
this mode, however the unit will be ready for the other operation modes.
