Audio Visual Equipment
1. Open tripod suitably wide so that it is stable with loudspeaker on it. Tighten all wing nuts to secure legs and pole. Set height so that loudspeaker controls can be reached by a standing person.
2. Have 2 people lift loudspeaker to fit on top of column as it is heavy. There is nothing to fasten it securely, but its weight secures it.
3. Point front of loudspeaker towards kitchen hatch. Keep it in this position.
4. Attach 3-prong (kettle type) power cable into bottom left socket of loudspeaker. Plug 13amp plug end into mains (blue) extension cable. Switch power on at 13amp wall socket (on side wall behind organ). Switch on loudspeaker on bottom right of loudspeaker back.
5. Setting master volume on back of loudspeaker. Check that display panel at top is set at correct volume. It comes on at -12 DB, but you must change it to -16. Volume of microphones is controlled from rear of loudspeaker (see below).
6. There are two small receivers for microphones with aerials sticking out of each. These communicate wirelessly with microphones. Each receiver has small power plug associated with it, which should be plugged into a 4-way extension cable run from second socket of mains (blue) extension cable.
7. Fix cables from back of receivers to back of loudspeaker — grey for head-worn microphone and blue for handheld. Indicator at front of head-mike receiver should read 864.9 MHz and of handheld receiver 863.5. There is on-off switch at front right of each receiver.
8. On back of loudspeaker, turn head-worn mike volume to 4 o’clock and handheld to 3 o’clock (stickers indicate this, but they may have fallen off).
9. Take handheld mike. Press red button and hold for 2 seconds to switch on. Ditto to turn off. (Warning: if you press briefly, it puts mute on!) Check battery level on display. If low, switch off and unscrew bottom end of mike handle to reveal battery compartment. Use only AA alkaline. Batteries should last for three or four meetings. Ignore knurled wheel on handheld as it gets into complicated programs – you change volume of both mikes from back of loudspeaker. Test volume.
10. Proper holding position of handheld. Hold about 6 inches from your mouth, pointing its head towards your mouth, and speaking to head of mike, not side.
11. Take head-worn mike; headpiece and battery pack should already be wired together (if not, connect them, and keep them like that as they are hard to fix). Pinch sides of pack to open and reveal batteries and on/off switch (press and hold – mute comes on initially, so get beyond that). Display shows battery level. Pack fits on belts, pockets etc. It’s a transmitter so don’t hide it inside much clothing nor behind person. Headpiece fits over ears with bar at back of your head and mike on right side of mouth. Control volume from back of loudspeaker. (NB mute switch on top of battery pack has been disabled.) Warn wearer that anything said may be broadcast. Test volume.
12. Switch battery back off after test, BUT remember to switch on before wearer’s talk begins. Get person giving talk to do sound check 15 minutes before start of meeting. Tell person to stand well away from loudspeaker to avoid feedback.
13. Do not allow anyone to use handheld mic and head-worn mike at same time. This will almost certainly start system to feed-back. If two mikes get too close accidentally, reduce volume of one of them immediately.
14. From back of loudspeaker. When doing Q&A, since people talk at different volumes, it is useful to have operator standing behind loudspeaker to change level.
15. When you pack equipment away, wind up the cables neatly.
16. There is a contents list to be checked each time.
