If you plan on interfacing it with your radio, You might want to use a Direct Box between your radio & mixer. You can get a Direct Box that has balanced in & out unbalanced in and balanced out Also ground lift switch to Isolate the grounds of your rig from the mixer. Many have attenuation switches in the event your level is too hi. Also on many rigs there is a ACC jack on the back that has a line level input terminal like for a sound card. You can use this input for your mixer and leave the existing mike. You can also obtain a separate PTT switch here. Due note, most mixers have a balanced output, ether a XLR jack or a TRS jack. If you use the XLR term 2 & 3 are the balanced out, with a TRS the T & R are the balanced output. The term 1 or the S are ground which you may not want connected. If your rig is old tube type do not hook up external equipment without knowing what you are doing as many older rigs have High Voltage on there in/out jacks. Robert

You can find audio mixers cheap since they have undergone several generational updates in recent years. They are basically small mixing boards. A church may have an old one they might part with cheap, or Guitar Center or just google. You don’t need the latest.

I use an Alesis Multimix 8 (It’s USB enabled to hook directly to a PC and has multiple inputs) It’s going to take quite a few cables and adaptors to make all that work though. You also may need a larger mixer with more inputs depending on what all you want to add. You also may need some type of isolation transformer if you plan to use your headset to talk on your radio if you get any hum. There is a lot of info out there you’ll need to do your research before buying though. Example - a lot of mixers say ‘USB’but are not able to plugged into a PC - you can plug a memory stick with MP3’s into them is what they are referring to.

I operate both my PC and game console over the same headphones simultaneously. However they give me issues sometimes depending on what audio equipment I use (eg, Video Monitor HDMI output. sound card output, or Zoom H4N Pro output), and I don't know how to isolate them to use whatever I want. I use Sony MDR-7506 headphones and I want to integrate my HAM radio equipment into the same headphone loop (I want to hear all at the same time, PC, Console, HAM radio). I was wondering if there are any ways of /or tools for isolating interference between headphone inputs and my actual physical headphones when I have several inputs (eg, game console, PC, HAM radio) Kori Rahman KI5MKU Cell: (770) 298 8516 <mailto:kori...@gmail.com> kori...@gmail.com ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org <mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org <mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org
