Members Gizzyboo Posted November 22, 2010 Members Share Posted November 22, 2010 Hi, just wondering if you can hook up a set of powered speakers (L & R) to a powered mixer. I'm thinking, no. Link to comment Share on other sites More sharing options...
Members madjack Posted November 22, 2010 Members Share Posted November 22, 2010 Depends on the powered mixer. Many have line outputs as well as the speaker outs from the built-in amp. Using the line outputs would be fine, then the onboard amp can be used to drive passive monitors, etc. Give specific models for the mixer and speakers for more information.

Members Gizzyboo Posted November 22, 2010 Author Members Share Posted November 22, 2010 NX750P Yorkvilles and the mixer is a Gigrac 300 (by Soundcraft). Link to comment Share on other sites More sharing options...
Members jgthatsme Posted November 22, 2010 Members Share Posted November 22, 2010 Without looking at the specs for that particular mixer, there is also the possibility of using a device to reduce the signal strength from speaker level to line level (or mic level) in the event your particular mixer does not have line level outs.

Members rwhealey Posted November 22, 2010 Members Share Posted November 22, 2010 Use the "Main Output" TRS jack on the bottom right of the GigRac 300 FRONT panel and you'll be fine. Use a 1/4" TRS (not TS/instrument cable) cable between the mixer and the line input of your powered speaker. Do NOT hook up a powered speaker to the output of a power amplifier.

Members Mogwix Posted November 22, 2010 Members Share Posted November 22, 2010 Some powered speakers can accept a powered input, but not many, and there's usually a confusing and ill-described function that you MUST SELECT PROPERLY or else you'll destroy one or more pieces of equipment. That said, your mixer is bound to have line-level outputs of all it's mix busses. Link to comment Share on other sites More sharing options...
Members agedhorse Posted November 22, 2010 Members Share Posted November 22, 2010 Without looking at the specs for that particular mixer, there is also the possibility of using a device to reduce the signal strength from speaker level to line level (or mic level) in the event your particular mixer does not have line level outs. Whenever using a powered output to derive a line level signal, transformer isolation without a ground connection between the two devided is ALWAYS a good idea. There are too many amps these days that use class D power with full bridged output stages. These can have common mode DC voltage present and can destroy any line level input if this precaution is not taken. This is in addition to level matching.
