Abstract
A audio mixer is disclosed in which selection of audio monitor signals is accomplished by an edit select switch and a plurality of monitor select switches on a monitor select portion of the mixer display. When the edit select switch is enabled, selection of audio monitor source signals is controlled by an editor. When the edit select switch is not enabled, audio monitor signals may be selected by the plurality of monitor select switches. Selection of audio monitor signals is achieved regardless of whether or not the mixer is under general crossfade control by an editor.
Claims12
An audio mixer coupled to at least one input device providing a plurality of input audio signals to the mixer, and further coupled to an editor providing a plurality of control signals to the mixer, the audio mixer comprising:
- edit select switching means located on a monitor select portion of the mixer for enabling the control of the selection of one or more monitor audio signals from said input audio signals according to monitor selection control signals supplied from the editor, whereby at least one monitor audio signal is routed to one or more monitor source terminals on the mixer;
- and
- signal select switching means for selecting one or more monitor audio signals from said input audio signals, whereby at least one monitor audio signal is routed to said one or more monitor source terminals when said edit select switching means is not enabled;
- wherein said signal select switching means selects said one or more monitor audio signal regardless of editor control of non-monitor select functions performed by the mixer;
- and
- wherein said edit select switching means includes an analog edit select switch and said signal select switching means includes a plurality of analog switches, and the audio mixer further comprises:
- circuit means for detecting the respective positions of said edit select switch and said plurality of analog switches;
- logic circuit means for selectively coupling said input audio signals to said one or more monitor source terminals;
- and the audio mixer further comprises
- circuit means coupled to said means for detecting for supplying to said logic circuit means a plurality of logic signals indicative of the detected positions of said edit select switch and said plurality of analog switches;
- wherein said logic circuit means determines which of said input audio signals are coupled to said one or more monitor source terminals based on said plurality of logic signals.
A method of selecting monitor audio signals in an audio mixer coupled to at least one input device providing a plurality of input audio signals to the mixer, and further coupled to an editor providing a plurality of control signals to the mixer, comprising:
- enabling the control of the selection of one or more monitor audio signals from said input audio signals with an edit select switch located on a monitor select portion of the mixer according to monitor selection control signals supplied from the editor, whereby at least one monitor audio signal is routed to one or more monitor source terminals on the mixer;
- and
- selecting one or more monitor audio signals from said input audio signals, with a plurality of signal select switches, whereby at least one monitor audio signal is routed to said one or more monitor source terminals when said edit select switching means is not enabled;
- wherein said plurality of signal select switches selects said one or more monitor audio signal regardless of editor control of non-monitor select functions performed by the mixer;
- wherein said method further includes the steps of:
- detecting the respective positions of said edit select switch and said plurality of analog switches;
- and
- supplying to a plurality of logic circuits means a plurality of logic signals indicative of the detected positions of said edit select switch and said plurality of analog switches;
- and
- selectively coupling said input audio signals to said one or more monitor source terminals with a plurality of logic circuits based on said plurality of logic signals.
An audio mixer apparatus for selecting monitor output channels in a mixer console, comprising:
- a plurality of audio channels in the mixer console;
- a plurality of source select switch members provided on a display portion of the mixer console, said source select members being operable to generate a first set of source select signals which indicate which of said plurality of audio channels are to be routed to at least one audio monitor output terminal provided in the mixer console;
- an editor operatively coupled to said mixer console to provide control signals to control non-monitor processing of said audio channels and to provide a second set of source select signals which indicate which of said plurality of audio channels are to be routed to said at least one audio monitor output terminal provided in the mixer console;
- an edit select switch member provided on said display portion of the mixer console, said edit select switch member being operable to generate a signal indicating that said audio channels are to be routed to said at least one audio monitor output terminal in accordance with said first set of source select signals or with said second set of source select signals;
- and
- logic circuit means to decode said first set of source select signals and said second set of source select signals and, depending on the signal provided from said edit select switch, control routing of selected audio channels to said at least one audio monitor output terminal on the basis of either said first set of source select signals or said second set of source select signals;
- wherein the routing of selected audio channels is accomplished regardless of editor control of non-monitor processing of said audio channels in the mixer console.
