Re: [Frameworks] recording audio from a Pageant
The Behringer DI-20 direct injection box works well and is also about $25. Two channels, ground lift, several levels of attenuation. I use them to get speaker level outputs from projectors to balanced mic level inputs on a mixing board. ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks

> Those things have transformers inside them... not very good transformers, but > transformers nonetheless. Yeah, the quality varies. I've used some that worked fine. The thing is they're not THAT cheap, you still might need an attenuator, and the Rolls direct box is priced right at $25. I haven't tried it out myself, but someone on this list reported it does the trick. The only reasons I can see to go with something else is if you already have the isolation cable on hand, or you need to get the connection up in a hurry, faster than you can receive the Rolls direct box ordering online. > I've had very good results merely plugging in a 1/4 to xlr unbalanced to > balanced adapter and plugging the other end directly into my Canon xh a1 > camera. This probably works because: 1. running the camera off the battery eliminates the possibility of a ground loop. 2. the XH-A1 pre-amp is forgiving It's a good note though if you only need occasional audio recording, as a simple cable with the camera running on battery power is cheap and easy enough to be worth a try if straight capture is all you need. An XH-A1 will also serve as DIY telecine with a conventional 3 blade projector if you use the 24F setting (which can be tweaked for precise sync in the menus to match minor differences between projector speeds and exact 24). So no need for a 5-blade. [I have done this successfully and with no problems using exactly an XH-A1 and a Pageant, so it's not just 'should work in concept'.] Just don't tell Jeff you're going DIY, and/or promise that if the footage is really valuable you'll get it scanned with a Kinetta. ;-) HOWEVER, if you need/want to put any AC powered audio component in the chain, you'll likely have a ground loop problem (not that it hurts to check if you're not running valuable film in the projector). And even on batteries, your video camera's pre-amp may not be as chill with the impedance mis-match as Sean's XH-A1. ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
Re: [Frameworks] recording audio from a Pageant
I modified my pageant to use a 1/4" jack. I've had very good results merely plugging in a 1/4 to xlr unbalanced to balanced adapter and plugging the other end directly into my Canon xh a1 camera. From there I just set the audio gain on the camera to about 1/3 and adjust the volume knob on the pageant until it sounds good and the vu on the camera is just under clipping. Here's an example I put on YouTube a while back: https://youtu.be/xF-0sYsLP10 On Mar 10, 2016 7:22 AM, "Scott Dorsey"wrote: > > Alternatively, for the ground loop isolation, you can use the RCA > isolation cables they sell at car stereo shops. > > Those things have transformers inside them... not very good transformers, > but > transformers nonetheless. > > I'd use a decent DI box personally, if there was no way to bypass the power > amp. > --scott > ___ > FrameWorks mailing list > FrameWorks@jonasmekasfilms.com > https://mailman-mail5.webfaction.com/listinfo/frameworks > ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks

Re: [Frameworks] recording audio from a Pageant
I don't have the OP, only Scott's reply, so I'm not sure what setup is desired, But, in general, getting audio from a Pageant into a line-level input on recording gear is more than just connecting cables: you'll want an in-line isolation transformer to avoid ground loop hum, and a simple attenuator resistor circuit to match the level and impedance. A Rolls audio DB25 direct box should do the trick on both counts, and they're pretty cheap, about $25 IIRC. You'd need the cable Scott describes to connect the Pageant to the box. Alternatively, for the ground loop isolation, you can use the RCA isolation cables they sell at car stereo shops. You just need an adaptor for the end that goes to the Pageant, or better yet whack off the RCA plug and attach the plug that fits the projector. You might be able to get by without the attenuator, or find an attenuator cable (not a common item, unfortunately), or get someone handy to make one (just 3 resistors, schematics on the web…). > you could make a cable with a .206" plug on one and end a 1/4" phone on the > other and plug the thing into a DI box. ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
Re: [Frameworks] recording audio from a Pageant
That is a 0.206" plug. Switchcraft part S250. That said, you'll find that getting a tech to install a direct output from the phototube that bypasses the power amplifier will have better sound quality. But you could make a cable with a .206" plug on one and end a 1/4" phone on the other and plug the thing into a DI box. --scott ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
[Frameworks] recording audio from a Pageant
I want to run an audio cable out from a 16mm Kodak Pageant projector in order to record the sound track. The output (typically goes to the speaker that accompanies the projector) is almost, but not quite 1/4" Has anyone done this before and how did you manage to find an audio jack that would work?Thank you!Fereshteh___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
