Help needed using a microphone and audiowith an a/v reciever

[pokethepope]

I've been roped in to organising the a/v for our office Christmas party which will involve an awards ceremony and presentation, but have zero experience with this sort of thing!

A laptop will be feeding video and audio to a projector via HDMI. The projector has an aux output for the audio. I need to take this audio feed and combine it with a microphone, and send them to the venue's Marantz CR 611 receiver which is hooked up to four speakers.

Would this Behringer mixer be all that I need?

• Mic into line 1 using XLR cable
• Audio from projector aux output into line 2/3 using a 3.5mm-to-6.35mm cable
• Output from the mixer into the receiver's 'analog in' ports using a 6.35mm-to-RCA cable

Would I need an amp in there somewhere, or would the above work and be everything that I need? Any help much appreciated!

I use one of these for that very purpose:

Small, neat and not too techy

Yes your set-up will work. I'd take the audio direct from the headphone out of the laptop, some PJs and TVs will not pass the audio when using an HDMI input. Test well in advance!

There is also a chance by doing all that there will be a ground loop issue when the laptop is plugged into the mains (a loud hum).

So as suggested have it tested beforehand.

ETA: You can use the 2 track output to the a/v amp (if it's a mix of the inputs, it should be as it's to record).

The master outs are TRS balanced and balanced to unbalanced may introduce more hum but will work.

You can also use the 2 track input for your Laptop and assign it to the mix rather than use the TRS inputs. Everything will be balanced better.
