Portable PA System using iRig and JBL speaker

[marcelojmonteiro]

- Hi. I am a teacher and I would like build a portable PA system.
- I have a JBL Flip 4 Bluetooth Portable Stereo Speaker and would like to use with a microphone to speak to my students in the classroom.
- It is a small speaker and I don’t want to use anything bigger.
- I don’t want to use a wireless microphone
- This speaker does have a 3.5 mm jack and I would like to use it with a corded microphone.
- I intend to use a iRig Mic Lav
- Can I just plug the iRig Mic Lav in the 3.5 mm jack in the speaker?
- Do I need a preamp?

iRig Mic Lav cannot plug directly into your speaker. It would need a compatible iOS or Android device. You can find full Specs/requirements at https://www.ikmultimedia.com/products/i ... hp?p=specs

Is there a way to use my speaker with a corded microphone (any kind) using some kind of iRig interface? Does it work as preamp for the microphone?

The iRig microphones are not standalone, they are meant to plug into a mobile device or computer.

...and if I plug a microphone into the P10 input in an iRig 2 interface, Can I use it with my speaker?

In that case, you'd need to make sure the input was line level so for most microphones would require an adapter. Better for this scenario of using a microphone directly would be iRig Pre https://www.ikmultimedia.com/products/irigpre/

OK. So, if I have an iRig Pre and a XLR microphone, I could plug it directly to the 3.5mm AUX input in my JBL speaker, bypassing the iPhone?

No. I meant directly into your iOS device without needing an adapter to convert the mic to line level signal like you would for iRig 2.

The iRig Pre has an 3.5 mm output to plug a headphone. Could I use a P2-P2 cable to link the iRig Pre and the speaker?

You can output from the headphone jack to a powered speaker, but again you'll need to connect iRig Pre to a compatible device. It will not work standalone.
