Re: [Frameworks] Sound ? from an Eikie
When I show 16mm using an Eiki in my classroom, I use a guitar amp at the front of the room by the screen. There is a lot of buzzing when the film is not running so I unplug the cord from the projector, but when the knob is at 3:00 - in engaged mode and before the motor is running - there is no buzzing. The sound is good and loud, though not always perfect for that room.

Re: [Frameworks] Sound ? from an Eikie
Yes! That looks like EXACTLY what you need, and that's a good price for a readymade box. Connecting a 16mm projector with only a speaker jack to an audio system usually requires TWO things, and the Rolls box offers both: 1. An attenuator circuit to drop the output level from the speaker and match the impedance of the audio system input. 2. An isolation transformer to eliminate ground-loop hum. Some but not many projectors do have line level outputs, which don't require attenuation, but can still require isolation to prevent ground loop hum. You can usually get isolation cable with RCA jacks on each end at specialty car stereo stores. I haven't used that Rolls direct box, but I like that it has a variable attenuation circuit. I've made some simple one-value attenuation circuits, but every two devices you connect are a bit different, and it's hard to find one perfect level that fits all. Do note though, that the output of the Rolls box is a mono balanced line with an XLR connector – ideal for connection to an audio mixer, but to go directly into an equalizer you're probably looking at unbalanced stereo inputs (RCA jacks), so you'll probably need a custom cable for that. It should be a straight connection though — that is, you don't need another transformer to match the balanced out of the box to the higher-Z inputs of the equalizer. > I would recommend an attenuation box to cool down the speaker level signal. > > This is a pretty cheap one that works: > https://reverb.com/item/1133262-rolls-db25b-matchbox-direct-box-w-ground-lift-and-attenuator-switch?_aid=pla¤cy=USD&pla=1&gclid=CPKBxcr278gCFdKGfgodVzYDuQ ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks

I would recommend an attenuation box to cool down the speaker level signal. This is a pretty cheap one that works: https://reverb.com/item/1133262-rolls-db25b-matchbox-direct-box-w-ground-lift-and-attenuator-switch?_aid=pla¤cy=USD&pla=1&gclid=CPKBxcr278gCFdKGfgodVzYDuQ Hope this is helpful, Colin On Sunday, November 1, 2015, Francisco Torres wrote: > amp pedal may help > > > http://www.musiciansfriend.com/distortion-overdrive-effects-pedals/mxr-m-133-micro-amp-pedal > > 2015-11-01 8:52 GMT-04:00 Scott Dorsey >: > >> Burns?

Burns? Do you mean it clips? You could use a direct inject box from the music store if you have only a speaker output, but many of the eikis do have a proper line output and if yours does not it can be modified for one. --scott ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
[Frameworks] Sound ? from an Eikie
Hey Guys, I am screening a 16mm film that has its soundtrack optically printed on it. I am using an EIKI Xenon projector (Model EX-2000N). Since the sound from the projector is not that great I want to connect it to an equalizer rack and then to the PA system. The problem is that the projector sound output burns the equalizer ( I have learned this the hard way by burning a mixer). Do you know of any device or product that I could connect between projector and equalizer that will prevent the burning?
