A sound tech's primary duty is to assist the sound engineer and he has only one major responsibility, which is to be attentive. Load in and load out are second only to that primary responsibility.
Be Attentive
There are many facets to being attentive. First and foremost a good sound tech will attend to the needs of the engineer. Being attentive means paying attention. The engineer should have no difficulty at all communicating with his tech. Some of the common means of communication that are used during shows are:
Two-way radios or closed circuit comm. systems
Cell phones
Text messages
Hand signals
A nod of the head
A tech must follow his engineer's lead and must constantly glance at the engineer to see if he needs something. The engineer of any show has a lot on his mind. There is a lot he has to be responsible for to achieve truly professional results. The engineer must focus on several things at once: the artists, the sound, and the audience. One thing he should not have to focus on is getting his tech's attention. Anytime the engineer has difficulty communicating with his tech, the tech is failing to do his job. It is the responsibility of the tech to be attentive. The engineer should never have to leave his seat after the artists arrive. The sound tech must be attentive to the needs of the artists too. When the artists are setting up, it is the sound tech's responsibility to provide the following:
Hand each artist his or her cable and tell them, "This is for you," or "You plug in here" for example.
We are not to touch the artists' equipment and they are not to touch ours (within reason of course.) We have to touch the drums to mic them, but we politely ask if that is okay and we make sure to ask if any of our mics are in the way of the drummer. Singers, obviously, will find it necessary to touch our microphones and that is okay too. But, it is the sound tech's job to make all necessary adjustments to microphone stands to obtain the optimum placement for every artist. No artist should ever have to adjust a mic stand. Whenever that happens the sound tech is not doing his job. The artist should only have to focus on his instrument and his performance. Playing music is an emotional experience and if an artist becomes perturbed because he has to adjust his mic stand it will affect his emotions negatively and that will degrade his performance.
