Chapter 8 Sound Mixer - Datavideo TVS-1000 Instruction Manual

Chapter 8
TVS-1000 comes equipped with a sound mixer function, which is responsible for mixing sound
signals. It also allows the user to adjust the signal level for each source and separately for the
sound output.
The sound mixer allows the user to adjust the following channels:
• Selectable Channels such as Line IN (3.5 mm Phone Jack) which is an external input
channel (stereo analogue input on the input card);
• Media1 – an input channel from files played by the virtual player supported by the
Media1 Bin tab;
• Media2 – an input channel from files played by the virtual player supported by the
Media2 Bin tab;
• Capture – the TVS-1200 system captured audio input;
• Streaming – audio output of the streaming channel;
• Master Out – an audio output channel.
The signal level for each channel can be set with a slider next to the signal level bar. Additionally,
a separate Master Out slider can be used to set the output signal level. The Master Out slider is
also displayed next to the Program window. Sound can be adjusted from -42 dB to +10 dB. The 0
level corresponds to -10 dBV (-7.8 dBu or 0.316 V RMS).
Also, the following functions can be turned on for each input channel:
• Follow – This function mutes the sound of the selected channel until the video signal
associated with the sound source comes on air. This is related to Media1, Media2, and
the CAM source associated with Line IN. Switching on this function with a selected
channel causes the sound of a given source to be muted if the source is not streamed
(shown) to the PGM output.
• Solo – This function sends the selected signal to the output separately. Switching on this
function with a selected channel causes the other input channels to be muted. Only the
signal for which the SOLO function has been enabled is sent to the outputs.
• Mute – This function completely mutes the signal for a given source.
