When several microphones are needed and their levels must be individually controlled and mixed, a small portable audio mixer will be needed. Is not recommended except for capturing background sound.) One mic is needed in the field, it can simply be plugged into one of Typical for schools and training facilities. Introducing you to equipment that you could encounter onĪ job or internship, and not the kind of equipment that's Note that many of the settingĪnd monitoring status displays are in the form of small LCD screens Mic batteries, this is not an unusual occurrence.ĭigital audio console (board), such as the type you would find in a Given the fragility of mics, cables, connectors, and condenser Ready for quick use in case one of the regular mics suddenly goes It is also good practice to have a spare mic on the set During spirited discussions, for example, people Need to constantly watch (and adjust) the levels of each mic once the There is another important reason that mics should be checked before a production: the strength of different people's voices varies greatly.ĭuring the mic check procedure you can establish the levels (audio volume) of each person by having them talk naturally, or count to 10, while you use a VU meter to you set or make a note of the appropriate audio level.Įven after you establish an initial mic level for each person, you will Either way, it's immediately clear that someone goofed. Unless you do this, you can expect unpleasant surprises when you switch on someone's mic, and there is either no audio at all, or you faintly hear the person off in the distance through another mic. They should be carefully checked before the production begins. Mics represent one of the most problem-plagued aspects of production, Studio mic cables are normally plugged into three-prong XRL or CannonĬonnector receptacles mounted in the studio wall as shown in this six-connector Mic numbers ("lav 1") or talent names ("John") Used on the audio board channels to identify what mic is plugged into Needs to make a note on which control on the audio board is associatedĪ black marker and easily removed masking tape can be Only a 5 to 10 meter (15-30 foot) cord, mic extensionĬables may be needed to plug the microphoneĬannon connectors, as shown here on the left.Ĭan get confusing with a half-dozen or more mics in use, the audio operator Once they are inside an audio board, all audio sources become line-level and are handled the same way. Mic-level inputs handle the extremely low voltages associated with microphones, while line-level inputs areĪssociated with the outputs of amplified sources of audio, such as CD players. These sources all break down into two main categories: Through the master gain control to be recorded or broadcast.Īudio boards, consoles, and mixers can control numerous audio sources, Speaker is intentionally used in many studios so cue audio is not confusedĪudition allows an audio source to pass through an auxiliary VU meter to high quality speakers so levels can be set and audio quality evaluated.
