If there's plenty of audio, using a hard-wired splitter into an in-line attenuator for each headphone will allow each listener to set the volume independently without any additional equipment.
Small in-line attenuators are available from a variety of sources for a few bucks. One example is the Koss VC20 available for about $10 from sources here in the USA (http://www.radioshack.com/product/index.jsp?productId=2272471&tab=summary) Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dick Dievendorff Sent: Tuesday, June 30, 2009 3:34 PM To: 'Elecraft' Subject: Re: [Elecraft] [K3] Headphone Splitter/Amp I used a Behringer HA-400 briefly for our FD effort and quickly replaced it with a standard 2 phone jacks to 1 phone plug rigid adapter. I heard a very loud garbled monitor signal when transmitting on SSB with the HA-400 headphone amplifier in use. Our station wasn't grounded (at all), which would account for this difficulty. Next year I'll be more careful about grounding the station. I think it'll work out well. The two headphones we used were of different makes and models, and of course one was much louder than the other.
