What is a karaoke amplifier?
The amplifier is an audio device that is responsible for receiving input signals from karaoke players and karaoke microphones, and then mixing, processing, reproducing, and amplifying that audio signal to the speakers.
Basic functions of karaoke amplifier
Amplifier has the function of amplifying sound for loudspeaker devices, corresponding amplifier power, and speaker power will give the best sound quality.
The amplifier increases capacity and increases sound filtering ability for better sound quality.
The amplifier boosts speaker capacity and plays louder sound but cannot filter sound.
Popular types of amplifiers on the market today
People often classify amplifiers based on two main factors: functional characteristics and capacity.
Regarding functionality, we will have:
Pre-amplifier – Also known as pre-amplifier, used to amplify the input signal into a higher level signal before sending it to the power amplifier.
Power amplifier – A type of power amplifier that amplifies a medium-level signal into a higher signal level and sends it to the speaker for better sound quality.
Integrated amplifier – Is a combination of a pre-amplifier and power amplifier for one device.
Dual mono amplifier – A parallel independent amplifier is designed to integrate two left and right amplification systems that operate independently but are completely identical in characteristics.
Monoblock amplifier – Designed into 2 completely separate, heterogeneous blocks running separately for each channel, the special design makes each channel unique.
Regarding capacity, we will have:
Small power amplifier from 500 – 900w used for small speaker systems and simple audio equipment.
Average power amplifier from 900 – 1500w used for home audio systems and karaoke.
High-power amplifier from 1500 – 3500w used for large, professional sound systems.
Basic parameters are available on the amplifier
When choosing to buy an amplifier, users need to clearly understand the signals and basic specifications of the amplifier to choose a product that suits their needs:
Amplifier capacity – The unit in RMS here is the output power that determines the strength of the device.
Power gain – Calculated according to the logarithmic function between the input and output power of the amplifier, unit dB.
Frequency response – This represents the input frequency response for the amplifier device to operate linearly, usually from 20 – 20kHz.
Efficiency – The ability to bring output audio power up to input power.
Distortion – This is a comparison of the total harmonics between the output sound and the input sound.
Impedance – The output of the amplifier is usually designed at about 2–4–8 ohms. This is also the parameter that you need to pay attention to when pairing with the speaker accordingly.
Echo, reverb – These two parameters can be collectively called the effects of the amplifier. Echo is an effect that creates a ringing sound for vocals. Echo mixes the processed sound with the original sound to simulate the “vibrato” of the singer’s voice. Rever is a reverberation effect that contributes to creating a greater sense of room resonance by simulating echoes bouncing off walls.
Experience in choosing a karaoke amplifier for the family
You should remember that karaoke amplifiers have different requirements than amplifiers for sound systems to listen to music. Therefore, to make the most suitable choice, you need to pay attention to the following main issues:
- Choose a digital amplifier or a mechanical amplifier
Amplifier production technology is becoming more and more modern, what should you look for in that amplifier’s technology? There are two types of amplifiers on the market: digital amplifiers (Analog and digital) and mechanical amplifiers. However, these two amplifier lines both possess different technology and have different characteristics and features.
Mechanical amplifier: Mechanical amplifier has a quite reasonable price for Vietnamese users and is quite easy to use.
Digital amplifier: is an amplifier that is easier to use and has many newer technologies and features than mechanical amplifiers. Specifically: A digital amplifier gives quality, clear sound and eliminates the phenomenon of dryness. There is no hissing phenomenon for the microphone. You can install and save many profiles suitable for the voices of many people or many different music genres. Avoid situations where other people easily turn the knobs, causing the sound to be distorted. In addition, the digital amplifier also integrates a threshold locking feature that limits the sound intensity of the input and output, helping to protect the speakers from burning out.
- Amplifier capacity
For karaoke systems, the power of the amplifier is a particularly important thing that you must pay attention to. The strength of the amplifier is expressed in its tension, accuracy, and clarity when you use the amplifier. A good, quality amplifier product should not make shrill howling noises, nor should there be any hissing noises when you adjust the volume down. Capacity also affects the sound quality of the speaker.
When choosing an amplifier based on capacity, you need to pay attention to whether the room area is suitable for that capacity level or not. Next is how much power the speaker can use at that power level. If the speaker’s capacity is greater than the amplifier, it will not be able to produce good sound, and if it is too large, it can cause the speaker to burn out. If paired with low-sensitivity speakers, the amplifier will often lose power. In this case, you should choose a large-capacity amplifier.
Each amplifier usually has 2 power levels. These are RMS and PMPO.
RMS power: is the average power level for speakers operating at an average level.
PMPO power: is a parameter that represents the peak power of the amplifier achieved in a short time, that is, the maximum power threshold (if the maximum power of the speaker is less than the maximum power of the amplifier when this threshold is reached, it will cause a fire loudspeaker).
Depending on the number of speakers you want to install, choose to buy a 2-channel or 4-channel amplifier that is most reasonable. If you only use a pair of karaoke speakers, choosing a 2-channel amplifier is perfect. If you have 2 pairs of speakers, using a 4-channel amplifier is best.
- Sound quality of the amplifier
Not only amplifiers but for any electronic audio device, you must pay attention to their quality. You should choose an amplifier with a good sound processing filter, giving clear sound without noise.
To choose an amplifier with good sound quality, you should choose a device with music adjustment channels such as a karaoke mic for in-depth adjustment. Good microphones show how well they transmit and reproduce sound when you sing. Even though your voice is weak or not loud, the sound through the mic is still loud and accurate. The special thing is that the ECHO button and REPEAT button must work stably.
Many amplifier companies use separate echo and reverb processing technology to help you adjust more easily and in-depth. This type of amplifier has a wide frequency response, effectively minimizing distortion and howling.
In addition, when choosing an amplifier, you need to pay attention to the bass and treble. The bass must be strong and play fast, powerful music. m clear treble, giving listeners different feelings about different types of musical instruments. How to choose a good amplifier for a karaoke system is an extremely important thing that everyone needs to pay attention to.
- Use a 2-channel amplifier or a 4-channel amplifier
Depending on the number of speakers you want to install, choose to buy a 2-channel or 4-channel amplifier that is most reasonable. If you only use a pair of karaoke speakers, choosing a 2-channel amplifier is perfect. If you have 2 pairs of speakers, using a 4-channel amplifier is best.
- Brand and cost
Reputable brands are always the top suggestion to choose to buy good quality amplifiers. Product features and characteristics that have high accuracy, high amplifier durability, and genuine amplifiers with warranty will help users feel more secure in to use.
Consider and compare prices between brands and products with the same specifications to evaluate the appropriate purchase, according to the financial budget that the user chooses to buy, but quality and appropriate specifications are still weak. Top tips to avoid damaging your family’s speakers.
General amplifier usage instructions
- Principle “Last on, first off”
To put it simply, the amplifier will be the last part to be turned on when needed, and when not in use, it will be turned off first. Once the amplifier is turned on, it is ready to amplify any signal it receives. If you turn on the amplifier first, it will amplify the signals when turning on/off CDs, speakers, microphones, and other devices. This reduces the sound quality of the speaker day by day. This should be considered an immutable principle in using sound systems.
- Detailed instructions on adjustment knobs
Step 1: Turn off the device and plug in and connect devices such as microphone, speaker, etc. Set the mic volume to the lowest level
Step 2: Adjust all volumes such as total volume, microphone, Echo… to the 12 o’clock position (middle position).
Step 3: Turn on the amplifier and then test the microphone, this part is important. Depending on the area of the theater room, we will adjust differently or if the room has a good or poor sound absorption system, we will have different adjustments. Gently turn the Echo, Dly, and Rpt volumes to the right or left about 10 to 15 degrees. As long as you hear your voice is not too loud and does not repeat too many times.
Step 4: For people with treble-oriented voices, adjust the treble volume to the left about 10 to 90 degrees. With a bass voice, we do the same thing. People with weak voices should adjust the Mid volume between 10 and 45 degrees but don’t overdo it because it will cause very uncomfortable howling and hissing.
Step 5: To sing well, you should adjust the karaoke amplifier with the music volume so that the music is not louder than the microphone. Then, if howling occurs, adjust the Hi of the total volume to the left about 10 to 90 degrees. In some cases, when you adjust the microphone very well, but every time you hear a howl, this problem is due to the high Hi frequency of the microphone and you should re-adjust this frequency.
