For starters, I would begin with a 100K ohm series resister, and a 10K ohm shunt resister. It is the ratio of the resister values in each leg ( left or right channel) which will determine the amount of attenuation you wind up with. ![]() You need to connect a resister in series with each ofthe left and right” hot “leads ( between the mixer and the camera ), and a ” shunt “resister from the junction of each ofthe series resisters ( on the camera side ) to the common ( or shield ) which is continuous from the mixer to the camera. I will also assume that the output connectorsof your mixer are unbalanced, each having a ” hot ” wire ( coaxial core or 1/4″ plug ” tip “), surrounded by a shield ( “commond “or ground ). You have “unbalanced ” inputs on your camcorder, I assume, since the mic input is stereo on a mini TRS ( tip-ring-shield ) connector. If you know which end of a hot soldering iron to pick up, the price of your solution is considerably less than $ 15/channel. “ I was hoping someone would say something like “just buy this $15 attenuator cord from XXX and you’ll be just fine.” No such luck? “ ![]() So, you probably can fiddle with the HF20 input levels for use with a soundboard, BeachTek boxes will allow you to do that better than the HF20 at the expense of adding some audio complexity but if you used anauxiliary audio device you’d have two copies of your sound -redundancy is good. I’ve never tried one becausethe price was the same for a ZOOM and Earl has written about them before and he isabsolutely right, they are worth the money, piece of mind, ease of use, easy to monitor. I see that BeachTek and others make a boxthatadds XLR inputs to cameras like ours. I’ve used a ZOOM H2 hooked up to a soundboard for music and vocal and my HV20 recording theambient hall sound – I sync them up later. If it’s a critical event, you want back up sound from some other device. I have to tell you though, if the HF is like the HV, it’s really hard to monitor the levels and the indicator levels aren’t so accurate. With the HV20 you can select auto or manual levels. If the mic input on the HF20 is like the HV20, you’ll have to deliver signal from your soundboardto a 1/8″ stereo mini-plug. ![]()
