Understand the "language" in live sound reinforcement performances


When newcomers first come into contact with live audio, they need to understand some terms that look like a new language. These terms are often heard in amphitheaters, convention halls, theaters and similar venues.

Although not often seen in clubs, some experienced veterans can be heard using some terms. This is especially true when working with regional or national tour performers in the club.

You may hear experienced producers yelling at various instructions, such as: "Place the bracket on the left side of the live sound reinforcement and place the speaker in the 'central position behind the stage'."

Learning common terms can make everyday work smoother. In the above statement, “live sound reinforcement” refers to the position of the live sound mixing console. And "the left side of the live sound reinforcement" is viewed by the sound engineer facing the stage.

"After the stage" refers to a part of the stage farthest from the audience, and "center" means... yes... it is the center of the stage. Therefore, the place that is positioned at the "central position in the rear of the stage" is the center of the rear of the stage. (Editor's note: The ancient European people built the stage into a sloping shape so that the rear of the stage is actually slightly higher than the front part. This way, the audience can see all the performances without the actors behind the stage. The strength can only be seen by some occasionally exposed scenes. This is the source of the term "post-stage" & "front of the stage" based on the literal meaning.)

Perhaps the simplest and most common term is the "left area of ​​the stage" and the "right area of ​​the stage." These terms are viewed from the perspective of an actor facing the audience. When standing on the stage and facing the audience, the area on the left is the “left area of ​​the stage”. Obviously, the area on the right is the "right area of ​​the stage."

Here are some simple but important terms you should know in this line of work. Common abbreviations are used where appropriate. Many times you will find these abbreviations printed on the device.

In addition, it is common to use only abbreviations in the stage layout. With this in mind, the most important thing is to familiarize yourself with these common abbreviations.

Location term

Stage Left Zone (SL): The left side of the stage is viewed from the perspective of the actor facing the audience.

Stage Right Zone (SR): From the perspective of the actor facing the audience, the right side of the stage.

Stage front (DS): The stage area near the auditorium. You can think of it as the front of the stage.

Rear of the stage (US): The stage area farthest from the auditorium. You can think of it as the rear of the stage.

Center of the stage (CS or C): It is literally meaning.

Off-Stage: Refers to the stage area outside the main performance area.

The above terms can be combined to describe more stage positions. For example: the left side of the stage (DSL): refers to the front of the stage (the front part of the stage closest to the auditorium) and the left side of the stage.

Other common stage position terms and abbreviations are

Downstage Right (DSR)

Downstage Center (DSC)

Off-stage Left (OSL)

Off-stage Right (OSR)

Upstage Left (USL)

Upstage Right (USR)

Upstage Center (USC)

Right side of the stage (DSR)

Center in front of the stage (DSC)

Left side of the stage (OSL)

Right side of the stage (OSR)

Rear left side of the stage (USL)

Rear right side of the stage (USR)

Rear center of the stage (USC)

Note: The term “background” does not apply to a position on the stage. It refers to the area behind the stage (or sometimes on the side of the stage), including dressing rooms, storage rooms, production facilities, etc... This area is not visible to the audience.

Live Sound Reinforcement (FOH): When this term is used to refer to a location, it means that this area is placed (or will be placed) on the live sound mixing console for the show. It is sometimes referred to as Mix World. When not used as a positional term, it can be used in terms such as FOH speakers, FOH mixers, FOH amplifiers, and the like. In those usages, it represents the composition of the PA system for "House" (the PA system here is the sound for the listener, not the monitor system used by the actor).

Monitor (MON): This is an area where the monitor monitor is almost always on the outside of the stage. Also known as "Monitor Beach", "stage tuning area."

Sound Wings:: Stand-alone risers (sometimes part of the main stage) placed on either side of the stage, with speakers stacked on top. Sometimes referred to as "side view".

Spot Bay: An area reserved for lights and operators. It can be a vertical board, a gantry or a special area. Also known as the "live (light) shelf."

Working term

Stage Plot: The stage layout is a categorized "map" that shows you a rough layout of the stage.

Show-Call: Preparing for a show call is a work that anyone must do in a show.

(Note: The correct approach is generally to have all the staff responsible for the show call "black". That means wearing black pants and a black top.)

Hit: Sometimes people ask questions like "When does the show start?" “Hit” refers to the start time of the scheduled performance.

Strike: A project being "strike" means it was taken off the stage. You may be told to "take away the guitarist's vocal microphone." In this case you will need to remove the microphone from the stage (or skip this step when setting the stage layout.)

Set Change: This is the process of clearing the show on the stage and preparing the stage for the next major show.

Loader: These people are assigned to truck/trailer for unloading. They had to remove the equipment from the truck, during which time others transported their equipment to the stage.

Pusher: These people are responsible for "pushing" the equipment that the "loader" unloads into the stage area.

Stagehand: These workers wait for equipment in the stage area and place the equipment sent by the “transporter” on the stage. Also known as "Hands."

(Note: 1. Once the loading and unloading personnel and the transport personnel have completed their work, they are also responsible for other work. 2. When unloading, the loading and unloading personnel will still be assigned to the truck/trailer, but in many cases all other back-office workers will also To disassemble and transport your equipment, you don't have to delegate the delivery of the goods. This is a different assignment, so it is up to the staff responsible for verification.)

Crew Chief/Stage Manager: This position is directly responsible for the orderly loading, installation, setup changes, and uninstallation process.

LD: Light guidance. The main lighting operator.

Spot Op/Spot Operator: The staff responsible for operating the tracking lights during the show.

Technician (Tech:): Usually refers to a staff member who has knowledge of the "system" of the entire system or part of the system.

Band Engineer/BE: The engineer responsible for mixing the band formation.

System Engineer (SE): An engineer who is responsible for viewing the configured system and performing accurate operations.

Focus: After hanging the lighting fixtures in the show, the LD can use it to “specify” a fixed target, covering the central part of the stage. This is called "focus."

Dressing Cables: Use the Gaffer tape to secure the cable to the stage for a clean, safe operation.

Spike the Stage: A term that refers to the location of a project that may or will be moved so that it can return to its original position during Setup Change.

project

Backline: This term has the same meaning as a band device and can be interchanged with it. Including guitar amplifiers, drums, etc... This refers to the project itself, not the stage area.

Monitor (Wedge/MON): A term commonly used for stage monitors.

Drumfill: The drummer's monitor. It can be a simple "monitor" or a larger device, depending on the actor's device.

Sidefills: Stage monitors placed on one side of the stage to provide independent monitoring for musicians.

Stacks: Used to represent speakers (FOH stacks) used by viewers.

Flown Speakers: Hang the speakers through the truss (or other method) above instead of simply stacking them near the stage.

Distro (PD): AC power distribution center. Used to power larger displays that require far more power than the normal circuit can provide. Also known as "Power Distro."

Gaffer tape (Gaff): Professional tape for “wrapping cables”. Although similar in appearance to the cloth tape, the gaffer tape has only a few residual residues, and it has no reflective surface and is easier to tear. It is the current professional choice.

Pin 1 Lift: This is an adapter or a balanced microphone cable that is not specifically connected to the end of the cable plug. This is a safer method to reduce or eliminate noise caused by ground loops. It is very dangerous to pick up the AC ground wire and it is never recommended.
