Linear Power Supply – Audio Phonic
A linear power supply is one of the most important components in high-quality audio systems and electronic devices. It is widely used in amplifiers, DACs, studio equipment, and sensitive audio gear because it provides clean, stable, and low-noise power output.
At Audio Phonic, we provide detailed information about linear power supply, its working principle, benefits, applications, and why it is preferred in professional audio systems in Bangladesh. This guide will help you understand everything you need to know before choosing a power supply for your audio setup.
What is a Linear Power Supply?
A linear power supply is a type of power supply that converts AC (alternating current) into a stable DC (direct current) voltage using a transformer, rectifier, and voltage regulator.
Unlike switching power supplies, linear power supplies operate at low frequency and provide very clean output with minimal electrical noise.
Basic Components:
- Transformer (reduces voltage)
- Rectifier (converts AC to DC)
- Filter capacitors (smooths output)
- Voltage regulator (stabilizes output)
Key Function:
- Provide clean and stable DC power
- Reduce electrical noise and ripple
- Ensure safe operation of sensitive audio devices
Why Linear Power Supply is Important in Audio Systems
In audio systems, power quality directly affects sound performance. A noisy or unstable power source can introduce distortion, hum, or unwanted interference.
Importance in Audio:
- Ensures clean sound output
- Reduces background noise
- Improves clarity and detail
- Enhances amplifier performance
- Protects sensitive audio components
This is why audiophiles and professionals often prefer linear power supplies over switching alternatives.
How Linear Power Supply Works
The working process of a linear power supply is simple but highly effective.
Step-by-Step Process:
1. AC Input
The system receives alternating current from the main power source.
2. Step-Down Transformer
The transformer reduces high voltage AC to a lower level suitable for electronics.
3. Rectification
A rectifier converts AC into pulsating DC.
4. Filtering
Capacitors smooth the pulsating DC into more stable DC voltage.
5. Regulation
A voltage regulator ensures the output remains constant and stable.
This process results in a clean and noise-free power supply ideal for audio equipment.
Linear Power Supply Price in Bangladesh (Overview)
Although prices vary depending on wattage, build quality, and brand, linear power supplies are generally more expensive than switching power supplies due to their heavy transformer design and high-quality components.
Price Range:
- Small audio linear power supply: BDT 2,000 – 5,000
- Medium power units: BDT 5,000 – 15,000
- High-end professional units: BDT 15,000 – 50,000+
At Audio Phonic, we help users understand pricing and choose the best linear power supply for their audio systems.
Benefits of Linear Power Supply
Linear power supplies are preferred in audio applications for several important reasons.
1. Ultra-Low Noise Output
They produce very low electrical noise, which is essential for clean audio.
2. Stable Voltage
Provides consistent voltage output, ensuring stable device performance.
3. Better Sound Quality
Improves clarity, detail, and dynamic range in audio systems.
4. Simple Design
Fewer high-frequency switching components reduce interference.
5. High Reliability
Long-lasting and stable performance under continuous use.
Linear Power Supply vs Switching Power Supply
Understanding the difference helps in choosing the right option.
Linear Power Supply:
- Low noise
- Heavy transformer
- Better for audio systems
- Less efficient but cleaner output
Switching Power Supply:
- High efficiency
- Lightweight
- More electrical noise
- Common in general electronics
Conclusion:
For audio applications, linear power supplies are preferred because sound quality is more important than efficiency.
Applications of Linear Power Supply
Linear power supplies are widely used in professional and high-end audio systems.
