Hisonic HS122B-HL Rechargeable Portable PA System with Dual UHF Wireless Microphones (1 Handheld + 1 Belt-Pack) - Perfect for Outdoor Events, Public Speaking & Live Performances

I am a real estate trainer and hold seminars around the country. I speak mainly in large real estate office training rooms or in medium sized hotel conference rooms. My class is a 3 hour PowerPoint presentation (with tons of interaction) and we generally have an audience of about 40 to 100+ attendees. I've done 33 live events over the past 10 months using this unit. It is a true CHAMP.I purchased this unit because I firmly believe that great audio is an essential component of a great seminar. Being heard loud and clear is so important to the reception of the event, and also allows you to speak in a normal voice with effortless ease. Attendees really appreciate it.I got tired of relying on house systems and showing up to find that the hotel or training room didn't have a lavalier/lapel mic setup - or that the audio system is down altogether.I use both hands a lot when I speak so a lavalier mic is a MUST for me. I've done a few events using a handheld mic - and although the audio is generally richer (because you can hold the mic closer to your mouth) the trade-off of having just one hand and speaking with a bent elbow for 3 hours is just not worth it.I originally tried using the Audio2000 AWM-6032UL - which is awesome but requires me to also pack a separate amplifier. The setup time was cut in half with this unit.This unit is an absolute Godsend. I love, love, LOVE it!! In fact just last week I arrived at an event in Baltimore to find the sound guy frantically trying to piece together the house sound for the event. It just wasn't working and showed no signs that it would be working anytime soon. When I pulled out my trusty Hisonic he was absolutely blown away. I received a high-five and a bear hug. He had never had a speaker show up with their own sound.For more than 5 years I spoke at events and have learned that I can NOT afford to rely on house audio. No matter where I travel I will always take this unit with me - even if they say they provide audio. Of course I actually prefer great 'house audio' with a lavalier mic system and will use prefer it over the Hisonic when I have the choice (and it doesn't cost extra). When the house audio is awesome, this system makes an invaluable backup and helps me rest at ease.This unit also keeps me from having to RENT sound equipment at the ridiculous prices that many hotels charge. I also really like having both the handheld and lavalier (which work simultaneously)! The handheld is great for audience participation as I can pass around the handheld mic and have my students ask questions with the benefit of being heard by all.In smaller rooms (50 or less people) I usually place the unit in the front of the room. For larger rooms of more than 50, I will often place the unit in the back of the room facing me. So far I have had ZERO problems with it and it travels well - even in my carry-on. The only issue with having it in your carry-on bag is that airport security will almost always want to have you pull it out and pull you aside to scan it separately – so I recommend you run it through the security conveyer belt by itself. Apparently it looks pretty suspicious when it runs through the x-ray. Pulling it out of your carrying and running it separately is not really an issue because it comes with its own carrying case with strap.This unit also has inputs for my iPod/laptop (playing music before the event) and an output (plug in and record audio to a digital recorder).This puppy is rechargeable so I don't even have to rely on power!!! I also like that it comes with a rechargeable 9 volt battery for the mic (which actually charges along with the unit itself). A word of caution - you have to remember to CHARGE the unit fully before you are going to use it (I do it the night before). It actually works fine plugged in as well, but if the 9 V rechargeable battery (included with the unit) is not charged and you don't have a backup battery you won't be able to use the microphone! I just wish the unit had the option to charge two 9V batteries at a time. Would come in handy when I use both mics at an event.This unit is an absolute MUST HAVE for any public speaker. I am strongly considering purchasing another one for when this one craps out - just in case the company stops making them!
