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

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

Use two people to mount or remove a loudspeaker. Wear hard hats while working with raised speakers.

What your team does

1. With Corey, mark the six positions from sheet 1-1 and make sure no speaker or tripod blocks an exit.
2. OpenSet and lockup each tripod.passive Pointloudspeaker using the CO-160a quick guide below. Complete one tripodloudspeaker legas infar as practical before moving to the direction the speaker tilts and add the sandbags Corey assigns.

With two people, mount the passive speaker, connect its labelled cable, aim it from the drawing, and then raise and lock the tripod.next. Place the two stage monitors on the stage floor as sheet 4-1 shows. Agree the exact position with Stage. Place the lobby and Accounting speakers on stable surfaces near safe wall sockets. These active speakers do not use the passive-speaker tripods. Test every speaker with the A/V Booth team. Walk the seating area with Alex and adjust only as directed.

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.

1. Open and secure the tripod — Figure 58

Put the tripod on an even, stable surface. Loosen the leg clamping screw ①. Open the legs until the cross braces ② are horizontal, then retighten the screw. Point one tripod leg in the direction the loudspeaker will tilt. Add the 5 kg sandbags Corey assigns.

2. Mount and aim the loudspeaker — Figure 59

Set the tilt adapter to about 5° downward and tighten the upper clamping screw ⑦. Turn lock ring ⑤ toward OPEN. Using two people, place the loudspeaker on the adapter. Keep the tilted loudspeaker above one tripod leg for stability. Turn lock ring ⑤ toward CLOSE until the loudspeaker is secure. Aim it according to the current CABR-2026 drawing.

3. Connect the speaker cable before raising

Confirm Audio Cabling has brought the correct labelled speakON cable. Connect it before raising the loudspeaker. Leave enough slack so raising the tripod does not pull on the connector. Keep the cable clear of the tripod mechanism and walkways. If the cable is not ready, leave the tripod lowered and return to it later.

4. Raise and lock the tripod — Figure 58

Loosen the height clamping screw ④. Hold button ⑤ while turning crank ⑥ to raise telescopic section ③. Raise the loudspeaker to the height in the table below. Release button ⑤ and continue turning the crank until the safety pin clicks into place. Tighten height clamping screw ④. Check the tripod, adapter, loudspeaker, sandbags, cable and all locks before moving away.

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.

The PLS-1, TP-1 and ALS-4 cases are heavy and must be rolled with enough helpers. Sunday teardown assignments will be added later; do not lower any speaker until the audience has left, power is off, and the teardown briefing is finished. When dismantling, lower the tripod completely before removing the loudspeaker, and use two people to lift it off.
