1. Sound system
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.
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.
Point front of loudspeaker towards kitchen hatch. Keep it in this position.
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.
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).
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.
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.
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).
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.
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.
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.
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.
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.
Keep both mikes well away from loudspeaker, or there will be feedback problems. If there is feedback, reduce volume 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.
When you pack equipment away, wind up the cables neatly.
There is a contents list to be checked each time.
Set up the big screen on the long table on the Weston Park side of the hall.
Put a 3-foot high table at the centre of the front row of seats. Plug the cable reel into the socket by the front door and bring the reel to the table. Put two black mats over the cable and fasten them down with gaffer tape, to avoid tripping. Put the projector on the table.
Plug the power cable into the projector power socket at the bottom left back. On top of the projector, a red light marked “power” will come on. Then press the “on” button which looks a bit like a smiley face on the top just to the left of the warning light. The “power” light then goes green.
If the red warning light comes on at any time, turn the projector power off for several minutes to allow it to cool down. Then start it again as above.
Put the laptop on a chair in front of the projector. Plug it into the cable reel. Then connect the laptop to the projector. There are two cables for this: a VGA cable, which has blue plug ends, and a HDMI cable, which has smaller black ends. Which to use depends on the socket in the laptop (the U3A one has both). HDMI is more up-to-date.
Back to projector
In order to raise the front of the projector so that its light hits the screen, press a button at the front centre bottom of the projector. A leg comes out to raise the projector. But this isn’t high enough, so you also will need to put a book, Baptist Praise and Worship, under the leg.
The top of the projector has two black knobs: one for focus and one for zoom. The thinner knob nearer the front is for zoom. Focus and zoom the lens so that the picture fills the screen.
There is a grey EIKI zapper. Press the On button. [NB It takes two AAA batteries.] Then, on the laptop set up what is to be projected. [The speaker will normally load the presentation into the laptop and set it to communicate with the projector.] To project it onto the big screen, take the zapper and press Input. The available inputs appear on the top right hand corner of the screen. Select the one you want by pressing the arrow buttons on the zapper. Then press OK.
There is a black Logitec Zapper, with a detachable USB stick in the bottom. Remove the stick and fit it into the laptop USB port. There is an on/off switch on the zapper’s left side. This zapper is to shift between pages of the presentation, using the left and right arrows. It also has a laser pointer, operated by the button on the top.
Turning off projector
To turn the projector off, press the Power button on the top. Power off? appears on the screen. Press the Power button again within four seconds. The power indicator starts to flash red, and the cooling fan keeps running. DO NOT unplug the power until the fan stops running.
