 Identify a location for main speakers. They should normally be pointing at the audience and ideally be as far as possible from the orchestra and as close as possible to the audience, to reduce feedback. In practice the venues TSC performs in have limited space and there are often very few choices for where to put the speakers.

 One of the choir monitors is wired in the standard way as just described, the other one is daisy-chained to the first one: an XLR cable is run from the pass-through output of the first monitor to the input of the second monitor.
+
+Monitors are checked from the lapel mic. This requires "Henric" input to be routed to each of the AUX outputs. After checking each monitor, reduce Henric level to the minimum because he shouldn't be in any of the monitors during the concert.
+
+== Microphones
+
+To check each microphone:
+
+1. Review the mixer setup sheet for whether the microphone requires phantom power. If yes, in Master Fader enable phantom power for the input.
+2. Verify mic preamp gain is set sensibly.
+3. Talk into or whack gently or otherwise make noise into the microphone. Verify mixer is seeing the signal in the correct input.
+4. Check the microphone off in the setup sheet.
+
+If mixer is not seeing any signal:
+
+1. Check if phantom power is enabled.
+1. Check other inputs - cable may have been connected to the wrong jack, commonly to one below the correct one (8 input positions over). If so, move the cable to the correct jack.
+1. If the input is a "dodgy input" and the microphone is a dynamic type, perform the following dance:
+  - Unplug the microphone.
+  - Locate a condenser microphone, plug it in instead of the microphone being tested.
+  - Enable phantom power in the mixer for the channel in question.
+  - Disable phantom power.
+  - Unplug the condenser microphone and plug in the original dynamic microphone.
+1. Check if the microphone has an on/off switch, ensure the microphone is turned on.
+1. XLR cable could be damaged/dead. Replace the cable.
