I was wondering how everyone sets up there speakers, its certainly important to get it right for the best sound, for myself, years ago when I used a ST1200 I made up a "wee box" [Roll Eyes]

on the projector stand so that I could connect the speaker output directly to the box, from there two extension speaker L/R outputs came out, the box was made so the speakers were wired in series and were 8ohms each, wired up they came to about 16ohms measured at the projector, I made the speaker boxes myself, cant remember the dimensions "it was long ago" but were made to work best for sound stripe, and worked well with just the single 8ohm speaker, it was said in those days that using normal stereo speakers was not the best option for stripe, the speakers were used a lot for away from home film shows, painted matt black and hung with old aircraft control cables, they were very basic, positioning them half way up the screen, "an old and rather large roller blind also hung up with control cables" [Eek!]

the speakers were angled towards the centre of the room, although its been years since they have been used I still think the sound I got from them and the old ST1200 was very good.

Another "wee box" [Roll Eyes]

I made in later years was for the GS1200, although with this projector I wanted to have it set up so if I had a mix of stereo or mono films on one reel. I could select on my "wee box", mono or stereo, and always have left and right input going into to the external amp, the sound split for stereo and joined fo L/R mono this I did and it still works well.

So how do you get on?

Hi Graham,
I connect from the AUX output sockets of the GS1200 to a Yamaha 10 band stereo graphic equalizer. From there to a little 3 watt amplifier box which has a switch for mono or stereo output, and from there to my main 60 watt Sony pro-logic stereo amplifier. I have five Bose speakers- a front center channel speaker, left and right front stereo speakers, and two rear surround speakers. The front center channel is used exclusively for mono films, and the front left and right speakers for stereo re-recorded films. The surrounds are only used for DVD's - I do not attempt Dolby surround on super 8 as it does not seem to work reliably.

I have a handy little headphone amplifier... although originally meant to boost the sound from portable players (walkman, CD player, MP3 player, etc.) and drive large studio headphones with plenty of oomph, this amplifier works amazingly well to increase the faint signal from my ST-1200's aux outputs to somewhere near line level. The box plugs right into my projector and from there I have a long audio cable running along the ceiling toward the screen (below which sits my main amplifier)... from there it's a standard affair of powering two stereo speakers left and right from the screen. Only thing I never got around to was making a switch to feed either track 1 and 2 into each respective channel, or feed only track 1 into both channels (for mono sound) - so for the time being, unless I'm showing a movie with stereo sound I just mute the right speaker and put the left one out in the center.

I use a self-powered 100W 'midfield monitor' (one of my mixing monitors when I do music) and hook it from the line out on ch.1 on my St1200 with excellent results (I only have mono films.) The 2-way monitor has a selectable hi-boost or cut on the back for any minor EQ and so far I haven't needed more tone shaping.

It works very well with my 16mm as well.
In my small apartment, the monitor has enough power to rip your head off (not that I would want to [Big Grin]

) and it is both very clean sounding and quite directional, given that it is designed for music mixing.

I highly recommend the idea of good self-powered speakers if you are looking to minimize your set-up and you don't have a permanent installation.

Best,
Claus.
