Introduction
Using the S278UHF professional portable voice amplifier, you can be heard from every angle! A little speaker can fill up to 10,000 square feet (1000 square meters) with 15 watts of powerful, clear, and undistorted music. Your vocal chords will experience less strain as a result of speaking with a lower voice thanks to the portable microphone. Megaphone speakers are incredibly simple to operate, have an amazing tone, and the volume control is simple to modify to meet different function and room requirements. Personal voice amplifier S278UHF with tethered and wireless headset microphone. The headset is cozy and easy to set up. Additionally, the wireless microphone has a headset and portable 2-in-1 design, making it simple to switch between the two modes to suit your needs.

For hands-free travel, the voice amplifier features an adjustable waist/neck band. It is a fantastic tool for those who need to communicate nonstop, notably teachers and other educators who depend on their voices in order to do their jobs. The portable microphone and speaker combo is perfect for lectures, seminars, training sessions, and public speaking.
10–12 hours for a personal voice amplifier; 3–5 hours for a wireless headset microphone. Charging is made incredibly simple by the included 5V charger and 2 in 1 multiple USB cable. Only 3 to 5 hours are required to completely charge them. A little megaphone can double as a speaker. The Bluetooth 5.0 incorporated into the S278UHF sound amplifier has a working range of 33 feet. Simple Bluetooth, AUX, and TF/USB input connections. With a USB or TF card in place, it can record audio that is being broadcast through the microphone.

LOW NOISE FEEDBACK AMPLIFIER
HOW VOICE AMPLIFIER WORKS
The signal (the input) is fed into a tiny loudspeaker that is inserted within your ear canal by a transistor-based amplifier, which enhances the signal numerous times so that you hear an amplified version of the original sounds (the output).
HOW TO TURN UP THE VOLUME
- Turn the volume up to the highest setting by pressing the volume “+” button on the headset microphone and using the speaker’s wheel key.
- Keep the microphone close to your mouth at all times.
HOW TO CARRY
You can put it on your neck or over your shoulder. You can also tie it around your waist.
HOW TO CONNECT MICROPHONE TO AMPLIFIER
- The XLR connection port on the bottom of the microphone should receive the XLR to 1/4″ cable.
- Connect the free 1/4-inch cable to the adapter’s 1/4-inch end.
- The “Line-In” port on the front of the amplifier should receive the free end of the 1/4-inch cable.
FAQs
What color is USB cable****
Black.
Is there a clip on the back so you can put it on your belt/pocket? Or do you have to use the strap?****
Yes.
Is there a way to prevent feedback? I kept cord stretched so full distance between mic and amplifier and still got lots of screeching.****
We have not experienced this problem unless it is turned all the way up.
can an extension mic cable be used to increase distance between mic and amplifier?****
Yes I believe it can. I haven’t tried that but it should work.
Can the wireless headset and wired headset be used at the same time?****
Yes, It can. When using, Please pay attention not to put the microphone close to the speaker or it will make a noise.
How to reset speaker, I am not able to put it on bluetooth mode. for first few days it worked now it always remains on UhF mode****
Short press the ” M” button to switch to another mode. If there is any problems, please feel free to contact us. We will try our best to assist you.
Does it have volume controls ?****
Yes. Both the speaker and wireless headset microphone have volume control button.
Does a microphone require an amplifier to function?****
The use of passive microphones is power-free. There are no internal amplifiers in them (though passive step-up output transformers can boost the output voltage of a passive microphone).
Do wireless microphones require speakers?****
Systems with wireless microphones are silent on their own. They need to be wired into a sound system.
Can I simultaneously utilize a microphone and speakers?****
Although different inputs and outputs are used for each, microphones and speakers can both be used at the same time. Playback is frequently performed via the speaker system, sometimes known as monitors.
Can microphones function without electricity?****
While some microphones need electricity to operate, some do not. Power is needed for microphones with integrated active electronics or non-electret electrostatic (condenser) capsules.
How can an amplifier improve audio quality?****
The source equipment’s low voltage electrical impulses are converted by the amplifier by greatly boosting their power so that they may successfully drive a pair of speakers to make sound.
How is electricity supplied to an amplifier?****
Before it is supplied to the speakers, an amplifier makes a larger copy of the input signal from a source, such as a laptop, turntable, or CD player. Your home’s mains electricity, which is delivered directly to the amplifier’s power source, provides the energy needed to accomplish this.
What’s the maximum number of speakers an amplifier can support?****
A generic low impedance power amplifier allows for the use of two or four speakers simultaneously. More speakers might be needed, though, depending on the venue.
How do a microphone and speaker function?****
In order to produce sound, the voice coil and its associated cone must move back and forth due to an interaction between the magnetic field produced by the current running through it and the magnetic field of the speaker’s magnet. When used in reverse, a dynamic microphone functions as a speaker. By altering sound pressure, the diaphragm is shifted.
