Sources and Targets

Date printed: 05.08.03
This chapter describes the basic concepts of the work with the Graphic
Controller (GC).
Generally, all audio signals available to the D950/Vista can be divided into
Sources and Targets. These names are used rather than "Input", "Output",
etc., in order to avoid any confusion regarding where the audio signal
comes from, and to where it goes.
Sources: A Source is anything that delivers an audio signal:
• Digital Input Interface (AES/EBU or MADI);
• Analog Input Interface (D19m Mic Input, A/D Converter);
• Channel Output (for example, Direct Out of Input Channel #24, Master
Output, etc.);
• Channel Insert Send;
• Bus Output (unlike analog consoles, within the D950/Vista any bus is a
valid audio signal source; for example, AUX Mono Bus 12 can be used to
feed an output interface, or to become an input to an input channel);
• Test Generator.
Targets: A Target is anything that can receive one (mono or stereo) audio signal:
• Channel Input 1 (first audio input to a channel; free for all input channels;
used to connect Sources to input/track monitor channels, such as a MADI
output from a digital multi-track to a track monitor channel, or the corre-
sponding bus to an output channel, such as a Group, Master, or AUX
channel);
• Channel Input 2 (second audio input to a channel; free for all channels);
• Channel Input 3 (third audio input to a channel; used for the test generator
connection per default, can be re-patched to any source at any time),
• Channel insert returns;
• Digital output interfaces (AES/EBU or MADI);
• Analog output interfaces.
Sources and Targets implicitly behave as mono or stereo, depending upon
their character. A stereo Source or Target can be treated, nevertheless, as
consisting of two mono parts.
Any Source can be connected to as many Targets as needed via the Patch
pages. However, a Target (stereo or mono) can have only one Source (ste-
reo or mono) assigned to its input.
