Your team safely places and aims the six passive loudspeakers. You also place theloudspeakers, two stage monitors and the active speakers for the lobby and Accounting.

Before starting, meet Corey, review the team'sLoudspeakers DC-83, and open sheetsSheets 1-1, 4-1 and 6-2 in the schematics.

Safety:
Use two people to mount or remove a loudspeaker. Wear hard hats while working with raised speakers. Keep hands clear of moving parts. Connect the speakON loudspeaker cable before raising the speaker,, and make surecheck every lock is secure before letting go.

Tripod placement:placement (see DC-83):
Place each tripod partly inside its chair section so the legs are sheltered from delegate foot traffic. Keep aisles, exits and walking paths clear. SetFully open and lock the tripodlegs, with one leg forward and two legs at the back,; keepingkeep the loudspeaker'loudspeaker’s tilt above the forward leg. Keep the legs fully opened and locked.

Agree the final speaker positions and tripod orientation with Corey and Alex before the sound check, and keep them unchanged afterward.

Confirm the XLR cable handoff with Audio Cabling and the power connection with Power before final placement. Place the lobby and Accounting active speakers on stable surfaces near safe wall sockets.

      Set up each passive loudspeaker — CO-160a quick guide

      These steps come from CO-160a Chapter 3, Tripods (TP-1), pages 5–6, Figures 58–59. Use the current CABR-2026 drawings for the actual speaker position, height and aiming.

      For the keyman

      Group Position and height Aim
      Front: SPK-1.1, 1.2, 1.3 About 4 m from the first row; normally 2.5 m high, with 1.2 at 2.4 m Toward sections A, B and C
      Rear: SPK-2.1, 2.2, 2.3 About 3.5 m from the first row; 2.5 m high Toward sections D, E and F

      All six passive speakers use about 5° downward tilt. If a raised speaker is above a walkway, keep at least 2.1 m clear underneath or use a barrier.

      When your speaker work is finished: Check with Lacey and help Audio Cabling with the remaining cable work.
