Troubleshooting : No Sound on Live Inputs
29 - 716
Broadcast WAV Files
BWF-P means polyphonic. I.e. multitracks within the same file
BWF-M means monophonic. I.e. one file per track
Pyramix Requirements
In order for Pyramix to recognize that separate audio files in these formats are actually part of a stereo or multi-
channel recording, Pyramix requires the following naming convention:
The filename of the different Tracks/Channels must be the same except for one section containing the Tracks/
Channels number as 3 digits surrounded by _## and ##_. For example: MyStereoSound_##001##_.wav and
MyStereoSound_##002##_.wav are seen by Pyramix as a single two Track media named MyStereoSound.
Other systems, the Zaxcom DEVA portable recorder for example, do not use the same convention. They may name
the files they produce in this fashion:
MyStereoSound-1.bwf and MyStereoSound-2.bwf. These files will be rec-
ognized by Pyramix as two mono media files.
Solution
MultiFileFixer is a small ‘tool’ application that automatically renames all files in a given folder and sub-folders,
that fit selected parameters, to follow the Pyramix convention.
In a normal Pyramix installation the
MultiFileFixer application can be found on the Windows Start menu:
Start > Programs > Pyramix > MultiFileFixer
No Sound on Live Inputs
Please carefully check the following points if there is no sound present on live inputs:
None of the connected inputs are muted (
MUTE ON).
None of the connected inputs are in
SOLO mode. In this case, all other inputs are muted.
The
DSP Load (displayed at the bottom the Pyramix window) should be in a range of 20% to 90%. A higher level
could produce clicks or occasionally mute the audio inputs.
In the
I/O Status window (right click on the bottom of the Pyramix window):
• All Input LEDs (corresponding to physical connections) should be active (light green).
• The Lock LED (corresponding to the chosen Sync Source) should be active (light red) and not flashing.
In the Mixer Settings window (right click on the mixer and choose
Settings):
In the
General Tab page:
• The project's Sampling Rate must match the external studio equipment's settings sampling frequency.
In the
I/O & Sync Tab page:
•The
Sync Source must be chosen so there is only one Sync Master for all connected equipment.
•The
Input Format must match the format of the incoming audio signal.
In the specific Tab page of each possible daughter card:
ADAT Tab: Only relevant for the outputs.
AES/EBU Tab:
• If the Reference is not in Auto mode and the Sync Source (in the I/O & Sync Tab page) is in Audio Input
mode, there should be a physical connection to the chosen reference.
• If the Sampling Rate Converters are set to Ref 1/2, 3/4, 5/6 or 7/8, the corresponding Inputs are muted.
Note: This is valid for the AES/EBU with SRC daughter card only.
