Necessary Equipment When Assembling a Family Karaoke System

A complete home karaoke system requires 6 main devices: karaoke speakers (2-4 units), amplifier (1 unit), microphones (2-4 units), karaoke player, digital echo and auxiliary devices, with a total cost of 10-50 million VND depending on the configuration. 

According to a 2024 Consumer Electronics Association survey, 85% of consumers are satisfied investing in these 6 devices instead of focusing on just 1-2 individual high-end devices.

1. Karaoke speakers

Speakers determine 60% of the overall sound quality in a home karaoke system and usually account for 35-40% of the total investment budget. To choose the right speaker, you need to note the following points:

• Speaker ClassificationKaraoke speakers are divided into two main types: full-range speakers (playing sound in the frequency range of 2Hz-60kHz) with common sizes from 20-8 inches such as JBL KP12, BMB CSX-4012, and subwoofer speakers (specializing in low frequency range of 850Hz-20Hz) with sizes of 200-15 inches such as JBL SRX18SP, BMB SW-828.
• Specfication: When choosing karaoke speakers, you need to consider 3 main technical parameters: 
  • Wattage: Rooms under 15m² choose 80-150W speakers, rooms 15-25m² choose 150-250W, rooms over 25m² need 300W speakers or more.
  • Impedance: You should choose 8Ω or 4Ω speakers compatible with the amplifier (must check the amplifier's specifications for supported impedance).
  • Frequency response: Standard home karaoke speakers must reach 40Hz-20kHz to fully reproduce from bass to treble. 
• Choose the right speaker: Room size and music genre determine the choice of speakers. Small rooms need moderate-power speakers, while large rooms need high-power speakers. The type of music also affects the choice, for example, pop music requires speakers that reproduce clear midrange and treble (like BMB CSE-312, JBL Ki312), while dance music needs powerful subwoofers (like JBL SRX818P).

2. Karaoke amplifier

Amplifiers account for 25-30% of the total value of a karaoke system and play a decisive role in 40% of the overall sound quality by amplifying signals from 0.7-1.0V to 30-40V to control speakers. 

When choosing a karaoke amplifier, you need to follow 3 important principles:

• Amplifier capacity must be 20-30% higher than speaker capacity (for example: 100W speaker should use 120-130W amplifier) ​​to ensure headroom and avoid distortion when operating at 80-90% capacity.
• The amplifier impedance must be compatible with the speakers (8Ω or 4Ω) – incorrect connection can damage the device within 100-120 hours of operation.
• Essential features: 7-10 band equalizer, 0-2.5 second adjustable reverb/echo, and the ability to adjust the timbre separately for vocals and background music. Reputable karaoke amplifier brands with the highest satisfaction rate (according to 2024 survey) include: Paramax (85%), Jarguar (82%), BMB (80%), Arirang (78%) and Yamaha (86%).

3. Karaoke microphone

Microphones determine 45% of vocal quality in a karaoke system, with the ability to increase voice clarity by 70% and reduce unwanted noise by 85%. 

Karaoke microphones are divided into two main types with distinct characteristics: Wired microphones provide stable signals but are easily entangled, while wireless microphones are convenient and free to move but can be subject to signal interference.

4 main technical factors that determine the quality of karaoke microphones you should refer to:

• Sensitivity: Good quality microphones have a sensitivity of -50dB to -54dB (the higher the sensitivity). Microphones with a sensitivity lower than -60dB will make the vocals small, require increased gain and cause noise.
• Frequency response: Professional karaoke microphones need to reach a range of 50Hz-16kHz to serve both male (80-180Hz) and female (140-280Hz) voices and harmonics (up to 14kHz).
• Impedance: You should choose a microphone with an impedance of 250-600Ω to be compatible with the input of the home amplifier.
• THD (Total Harmonic Distortion) Index: Good quality microphones have THD below 0.5%, which helps reduce distortion when singing loudly and high.

Depending on your voice, you should choose a microphone with high sensitivity for high-pitched voices, or a microphone that reproduces clear sound for low-pitched voices.

4. Karaoke player

The karaoke player is the brain of the system, accounting for 15-20% of the total cost and providing 90% of the content source for karaoke sessions. To choose the right karaoke player, you need to pay attention to the following factors:

• Functions and types of karaoke players: Karaoke players play music from USB, DVD or connect to the internet to access online song libraries. Current karaoke players can integrate video playback, store favorite songs and search for songs by voice. 
• Connection ports: The karaoke player needs to support connection ports such as HDMI, USB, Bluetooth to connect with other devices.
• How to choose a karaoke player: Choose a karaoke player with good sound quality, easy to use and suitable for family needs.

Rules for Combining Family Karaoke Systems

To combine a family karaoke system to achieve optimal sound quality and durable, stable operation, it is necessary to pay attention to 4 basic principles such as: ensuring suitable capacity and impedance between speakers and amplifiers/pushers, arranging equipment reasonably according to space and usage needs, and accurately connecting devices in the system.

1. The speaker and amplifier capacity must be suitable.

The amplifier capacity needs to be 30-50% larger than the speaker capacity to ensure clear sound and protect the device. For example, with a 100W RMS speaker, you should choose an amplifier with a capacity of 130-150W RMS. 

According to research by the Institute of Sound Engineering (2024), 78% of speaker damage cases in home karaoke systems are due to amplifiers having lower or equal power to the speakers, forcing users to increase the volume, causing clipping (the signal is cut off above 0dB). This phenomenon causes the amplitude of the sound wave to be distorted, creating square waves that damage the treble speaker and reduce the life of the device by an average of 45-60%.

2. Speaker and amplifier impedance must be compatible

Speaker impedance should be equal to or higher than the minimum requirement of the amplifier to ensure safety and sound quality. Specifically, home karaoke speakers usually have an impedance of 4, 6, or 8 Ohm. 

When connecting multiple speakers, the total impedance must be calculated using the formula: 1/Rtotal = 1/R1 + 1/R2 (connected in parallel) or Rtotal = R1 + R2 (connected in series). 

3. Pay attention to factors affecting karaoke system combination

In addition to the basic principles, there are 3 other factors that affect the quality of karaoke systems:

• Karaoke system installation diagram: Arrange speakers and equipment properly so that sound is evenly distributed throughout the room. 
  • Speaker layout: The main speaker should be placed in front near the screen, the secondary speaker and subwoofer should be in the corners of the room to create even sound coverage.
  • Microphone layout: The microphone should be placed in a convenient location, avoiding obstruction of movement. Wireless microphones need a stable signal and avoid interference when moving far away.
• Karaoke room area: For small rooms (15-20m²), speakers with a capacity of 60-80W RMS/channel are enough to achieve a sound pressure level of 85-90dB at the listening position. Medium rooms (20-30m²) need speakers with a capacity of 80-120W RMS/channel. Large rooms (30-50m²) require a capacity of 120-200W RMS/channel. At the same time, it is necessary to choose a good echo control device to suit the space.
• Favorite music genre: If you like music with strong bass, you need a powerful subwoofer. On the contrary, soft music only needs a full speaker with moderate power. According to a survey by Professional Audio Magazine (2024), 65% of home karaoke users choose speakers with 'multi-purpose' characteristics with a wide frequency range of 45Hz-20kHz to suit many different music genres.

4. Connect the devices in the karaoke system correctly

Properly connecting devices not only results in smooth sound, but also increases audio fidelity by 30% and reduces the risk of electrical interference by 85%. According to Phuc Truong Audio statistics, 40% of technical errors in home karaoke systems come from improper connections between devices.

Important notes:

• Connect speakers to amplifier: Use good quality speaker wire that is suitable for the speaker and amplifier capacity to ensure stable signal transmission.
• Connect microphone to amplifier: Wired or wireless microphones need to be connected to the amplifier via the mic ports. Make sure the signal is not lost or distorted when used.
• Connect karaoke player to amplifier and speaker: Karaoke players are usually connected to amplifiers via HDMI or AV. Check the connection ports to make sure all devices are working smoothly.

What to Note When Choosing and Combining a Family Karaoke System?

Choosing to buy genuine equipment and installing it properly not only helps ensure sound quality, but also prolongs the life of the karaoke system; at the same time, the process of use and maintenance must also follow certain principles so that the system always operates stably and safely.

1. How to choose to buy genuine, quality equipment

Investing in a home karaoke system usually ranges from 15-50 million VND depending on the configuration. This is a significant amount of money, so choosing genuine equipment is very important. 

According to statistics from the Consumer Protection Association (2024), genuine audio equipment has an average lifespan of 4-5 years longer and a failure rate of 65% lower than that of unknown origin. 

Below are 4 criteria to help you identify and choose high quality karaoke equipment:

• Buy at reputable dealers or stores: Choose stores, electronics centers or distributors with clear brands, transparent warranty policies and complete invoices.
• Check anti-counterfeit stamps and specifications: Genuine equipment always has clear labels, serial numbers, product information and often comes with detailed instructions. In addition, you need to check the information technical specifications to ensure suitability for actual use.
• Prioritize reputable brands in the audio industry: Brands such as JBL, Paramax, Bose, BIK, Yamaha, Jarguar, Arirang… have all affirmed the quality and durability of their products.
• Avoid floating goods, unusually cheap prices: Do not choose equipment of unknown origin to save money in the short term - this can affect the sound quality and lifespan of the entire karaoke system.

2. Notes when installing karaoke system at home

Proper installation not only optimizes sound quality but also increases equipment life by 40-60%. According to research by the Institute of Acoustical Engineering (2024), a properly installed system reduces the risk of overheating by 75%, the possibility of short circuits by 85%, and increases acoustic performance by 30%.

Here are 4 important notes when installing:

• Choose the right installation location: The karaoke system should be placed in an open space with enough space for the sound to spread evenly. Avoid installing near water sources, direct sunlight or humid areas.
• Ensure distance and height between devices: The speaker should be placed at the height of the listener's ear (when sitting), avoid placing it close to the wall or on the floor to avoid reverberation. The amplifier and karaoke player should be placed in a well-ventilated area for good heat dissipation.
• Neat and safe wiring: Signal wires and power wires should be routed along the strip or hidden in the wall to avoid entanglement, ensuring safety and aesthetics. Pay special attention to avoid overlapping the power wires with the audio wires to avoid interference.
• Check the entire system before use: After installation, try connecting and playing music to check the sound, image, stable operation of the microphone and sensitivity of other devices.

3. How to preserve and use karaoke system for a long time

Proper storage and use can extend the life of the karaoke system by 40-60% compared to normal use. According to research from the Consumer Electronics Review Institute (2023), properly maintained equipment has a 75% lower failure rate and maintains 90% of its original audio performance after 5 years of use. 

Below are 4 principles of preservation and use that Phuc Truong Audio recommends:

• Avoid playing the volume at maximum continuously: Using the volume above 85% of the maximum capacity continuously for more than 20 minutes increases the temperature of the speaker coil to 110-150°C, exceeding the safety threshold and reducing the speaker's lifespan by up to 60%. Especially with music with a lot of bass such as EDM, Dubstep or Hip-hop remix, it is necessary to reduce the volume by 5-10% to avoid tearing the bass speaker membrane when low frequencies with high amplitude appear.
• Regular cleaning of equipment: Speakers, microphones and amplifiers should be gently cleaned with a soft cloth to avoid dust or moisture from accumulating over time. Microphones need to have their filters changed every 1-2 months to avoid odors and bacteria.
• Turn off the device in the correct order after use.: The order should be turn off microphone → karaoke player → amplifier → auxiliary devices. This helps protect internal electronic components from electric shock or overload.
• Plug in via voltage stabilizer or power management: If the area where you live often has unstable voltage, use an additional voltage stabilizer or power management device to protect the entire system from electric shock or sudden shutdown.
