66 ARTEMIS Digital Broadcast Production Console Getting Signals Into Artemis
Tone Patchable to Output Ports
Tone can be selected to multiple points
throughout the DSP from channel inputs
to bus outputs, and is also available to be
patched directly to output ports for use
by others. This makes the tone oscillator
available as a externally available source
without using the DSP.
Tone is available as a source to
be patched to output ports from
>My Desk Outputs>Tone Outputs.
See Fig 3.
Tone Troubleshooting & FAQs
No tone present when selected
Selecting external tone will replace the
console oscillator whether external tone
is present or not. If internal tone is not
present when expected, check it is not set
to external.
If using external tone, check the correct
input ports are patched to the external
input (and that the tone generator is
connected, on and set correctly)
Also check that the oscillator level and
frequency are set to suitable values.
Tone on stereo downmixed/encoded
outputs lower than expected
When selecting tone to a surround output
bus, it is also applied to that buses’ LoRo/
LtRt outputs at the same level. This is
because tone is being applied at the final
output stage. With tone to line selected
the signal on LoRo/LtRt is NOT derived
from a Downmix or encoding of the
surround channels. The same level of
tone is applied to both the 5.1 and the
downmixed output.
Tone on stereo downmixed/encoded
outputs higher than expected
If tone is fed from a surround channel/
path which is in turn routed to a surround
output, the LoRo/LtRt of that output will
generally be of a higher level than that
on the surround legs as the LoRo/LtRt
output is derived from a Downmix of the
content on the surround legs as per the
Downmix settings.
Tone not present or low on LFE
channel of outputs
If tone is routed from a channel to
surround main output and signal is not
present on the LFE leg of the output,
this is likely to be due to the default
state of surround Main outputs having a
high frequency filter switched in on their
LFE leg. Reduce the frequency of the
oscillator to around 50Hz to see (and
hear) the LFE channel.
If desired, the filter can be switched out
or adjusted by selecting the Main output
as assigned, then selecting the LFE
channel from the surround spill panel and
adjusting the filters from an EQ panel.
