Sincerely Dear, hope the brigade will find out these fellows. and return even part of your equipment. Be careful in future, have some wireless tiny camera, insure your valuable equipment…
QUOTE if your local electricity supply is very intermittent and you expect to be using UPS battery power quite often, a pure sine wave inverter in the UPS is desirable as that means there will be better quality power when you have to use the UPS for your main power source.QUOTE
Thanks for all and your inestimable time you spent with query. I think our UPS will be fine. I let you know after conference…Thanks
According to discussed load (18 speakers – ± 15watts each) kindly help me select a choice between these amplifier
AMPLIFIER/Preamp: InterM PA6000 Rated Output (RMS) 240W
Amp/Preamp – Ahuja – MXA3500 350W RMS at 10% THD
Amp/Preamp – Ahuja TZA4000 – 200 x 200watts
Amplifier 2 channels 100 X 100 WATTS:- TZA2000 –This session will be held in a Public Hall converted on this occasion to serve our meeting…Perhaps in near future w’ll have our location.
Ok for earthing, I had a earth megger test with a result of 1.2 ohms. I already prepared accessories for a bonding of some items. Thanks for reminder…
Tell me please: from amp output to first group of speakers, I have 24 meters, you think I should absolutely increase the size of wires to maintained the load at 8 ohms OR it could be a bit more say 9 -10ohms ?Hi General Lighting
Our Para 1; 100v = Definitely, near future w’ll go on PA amp.
Yes, 5 Microphone,
Spiritual music 5 x 3min per day but NOT used at the
same time with microphone.Our Para 2: Ok for pre-amp output.
Our Para 3: Speakers purchased WITHOUT enclosure, Now under
preparation with carpenter.Our Para 5 – 6: Ok, anyway we just received a voltage stabilizer with .
filter for our equipment.WIRING: All wiring will be fixed/weld/clipped (by myself) directly to
speakers in their casing, no visible junction, except
the end to connect to amplifier output. I’ll make the wiring
this way just to avoid any connection on site, just hang
the wires, speaker’s casing, to “hooks” already fixed
on site. Nylon string provided between speaker’s casing as
prevention mis-handling or stretching of wires.NOTE= This is not a permanent installation, next session in
6 months time. We are waiting for a new building and I
propose to do all technical section a concealed installation.
Thence 100v system will be selected.Your Para 1: I got two choices of speakers:-
FIRST type 8 ohms 50 watts MAKE Rayden YD 103 and
SECOND type 4- 8 ohms 50-100 watts.MAKE Rayden R 103 Japan
Your Para 2: Am sure for 15W peak per Sp. But as your indication to make 200W or 300W.
Your Para 3: ECHO- Sixe of Room 15 X 15meters X 3 Height. Yes exactly as you said for two major speaker in front of assistance is not a good idea…The speakers will be at 2.5meters from floor…Yes I’ll group assistance surrounding the four central concrete columns just as you said in the vicinity of speakers…We always annouce to keep electronic gadgets OFF during sessions, thanks for these reminders…General Lighting
Your Para 1: What is it If we use for this session an Hi-Fi amp and in few month we choice an PRO amp PA with 100v ?
Your Para 2: I didn’t knew that the PHONO output can be used as pre-amp, So good ! I’ll keep in mind PA-6000A amp.
Your Para 3: I got two choices of speakers:-
FIRST type 8 ohms 50 watts MAKE Rayden YD 103 and
SECOND type 4- 8 ohms 50-100 watts.MAKE Rayden R 103 Japan
Yes for seperate transfo, I’ll be back soon.Your Para 4: Once we work out the need for 100v line system, I’ll be back for your assistance, for sure !
May be import from another country,Your Para 5: Already have a local fan, thanks for reminder….The system will stay on from 9 to 16hr for three days.
Your Para 6: Electricity study 220 volts can be interupt without notice from electrical company !
I prepare to insert a UPS in circuit just as standby, with additional batteries in stock !!
No Air Cond. just 4 ceiling fans and Fluo. lighting
What do you think about capacitor on mains 220v just to reduce incoming noise ?How you checked Thread 5 for size of wire:- 50/0.25mm X 25 meters from amp output to a group speakers extended with 30/0.25 to last speaker in this group which length is 11meters. Repeat same for the second channel.
With these size of wire I try to keep the load as 8 ohms as possible. Thus avoiding volt drop, I suppose !Hi General Lighting,
In the coming months, I’ll not miss to call attention for your paragraph one and three in thread 7 about electronic equipment. At this time we try to stick to series/para system, Hope no smoke at view point ! You know am confident if I follow your group instructions that will go.Thanks for echo defendant solutions
Yes, again thanks everybody, Am so happy about your valuable instructions, I’ll follow up all your indications.
Am NOT a highly qualified Electrician/Technician but your genuine Technics are most helpful…
All connections will be made be myself because the association has nobody to manage the system.
ECHO: 15 X 15 meters X 3 meters Height…Thanks for echo defendant based on some perimeter speakers perhaps some curtains too.
Now, if am not abuse your time, could you see how I can install a second amplifier from PRE-AMP of master amp, to drive two speakers on stage as return ! I know it’s a problem but I would like to set this, OF COURE, following your instructions once more…ANSWERS to your Questions:-
I got two choices of speakers:-
FIRST type 8 ohms 50 watts MAKE Rayden YD 103 and
SECOND type 4- 8 ohms 50-100 watts.MAKE Rayden R 103 Japan..
.
Also several choices for amplifiers
FIRST amp HI-Fi Sansui 150 watts Stereo and
SECOND Malanshi Hi-Fi Model OK 05 500 watts
THIRD Piasing HI-FI 150watts 2 channel and
FOURTH Ahuja PA 300 watts 2 channel and
FIFTH Amplifier PA 100 watts 2 channels:- TZA2000 and
SIXTH AMPLIFIER/Preamp: InterM PA6000 Rated Output (RMS) 240W 2 channel…FEEL FREE TO RECTIFY ANY ITEMS.
Thanks and regardsFantastic all of you, thanks much more for your valuable assistance.Am not an Student, am married and age 40, am just helping a religious association for this setup. Feel free to rectify any wrong method in the proposed setup. Let me give you some more data, the hall 15 x 15 meters x 3 height, the speakers fixed at 2.5 meters from floor, 18 speakers divided into 2 channel of 9 speakers each – 8 ohms 50 watts each NOT RMS – in series parallel : i.e. 8 X 3 = 24 / 3 = 8 Ohms with Resultant Impedance 8 ohms per channel and the max continuous demand output per speaker is 10 watts with 15 watts PEAK from time to time – Wiring 50/0.25 mm PER CHANNEL from amp output to the beginning of each start point of speakers thence with 30/0.25 to other speakers.Amplifier 450 watts X 2 channel, What is the lesser watts output ?. For 100 v line we certainly make it in few months. Speakers will be installed surrounding four central concrete columns…What can I do about echo, can I split some of speakers in the perimeters inside the building to eliminate echo ? The installation will start in one month time. Thanks for times spending just to help other.
