Welcome to the Bose Portable PA Community. Thanks for the interesting question. I'm glad you joined us.
I am thinking of purchasing the S1 Pro System as a PA system for indoor and outdoor yoga classes.
Are your classes for less than 75 people? The S1 Pro should be fine for that, perhaps more on the assumption that the environment is quiet and your listeners are attentive.
I would like to pair the S1 Pro System with a wireless headset which would allow me to preserve my voice and lead my classes hands-free.
Sure, The S1 Pro system can work with a wireless headset.
My question to the group is, will the S1 Pro System respond well to a wireless headset and what adaptations would I need to make in order to make this work.
Most wireless microphone receivers will have a 1/4 inch phone jack output or an XLR microphone output. The S1 Pro can accept both types.
I'm new to PA systems and their functionality. I appreciate any advice or recommendations about my speaker choice and welcome suggestions regarding viable headsets that work well with Bose PA systems; the S1 Pro System in particular. Many thanks!
When you're considering wireless headset microphones, for best results make sure the microphone is directional. This might be identified as
If the microphone is described as omnidirectional (or nothing is said about if the microphone is directional, it's probably omnidirectional), then look for a directional microphone because directional microphones (aimed at your mouth) will be less prone to feedback with your sound system. That applies to any sound system, not just the Bose S1 Pro.
Does that help?
