Pre Amplifier – by Audio Phonic
A pre amplifier (preamp) is one of the most important components in any audio system. It is responsible for boosting weak audio signals before sending them to a power amplifier or recording device. Without a proper pre amplifier, audio signals remain too weak, resulting in poor sound quality, noise, and distortion.
At Audio Phonic, we provide detailed information about pre amplifier, including types, uses, features, and buying guide in Bangladesh. Whether you are working on a home audio system, studio setup, or DIY electronics project, understanding preamps is essential for achieving high-quality sound.
What is a Pre Amplifier?
A pre amplifier is an electronic device that increases low-level audio signals to a level that can be processed by a power amplifier or recording equipment.
Basic Function:
- Amplify weak audio signals
- Reduce noise and interference
- Prepare signal for power amplification
- Improve audio clarity
Where it is used:
- Microphones
- Turntables
- Audio mixers
- Recording studios
- RF communication systems
A pre amplifier does not increase power output to speakers; instead, it strengthens the audio signal before further processing.
Importance of Pre Amplifier in Audio Systems
Pre amplifiers play a critical role in maintaining sound quality in any audio chain.
Why it is important:
- Enhances weak audio signals
- Improves clarity and detail
- Reduces background noise
- Ensures proper signal level
- Prevents distortion in power amplifiers
Without a preamp, most audio devices cannot deliver clean and usable sound signals.
Pre Amplifier Price in Bangladesh (Overview)
The pre amplifier price in Bangladesh varies depending on type, quality, and features.
Price Range:
- Basic pre amplifier board: BDT 100 – 500
- Microphone pre amplifiers: BDT 500 – 2,000
- Turntable pre amplifiers: BDT 1,000 – 5,000
- High-end studio preamps: BDT 5,000 – 20,000+
At Audio Phonic, we help users understand pricing and choose the right preamp for their needs.
Pre Amplifier Board
A pre amplifier board is a compact electronic circuit used in DIY audio projects and small audio systems.
Features:
- Small PCB-based design
- Easy integration into projects
- Low-cost solution
- Basic signal amplification
Uses:
- DIY speaker systems
- Electronics projects
- Small audio devices
- Educational purposes
Pre amplifier boards are very popular among hobbyists and electronics learners.
Turntable Pre Amplifier
A turntable pre amplifier (phono preamp) is specially designed for vinyl record players.
Why it is needed:
Turntable signals are very weak and require special equalization before amplification.
Features:
- RIAA equalization support
- Noise-free signal boosting
- Compatible with modern amplifiers
Uses:
- Vinyl record players
- Hi-Fi audio systems
- Home audio setups
Without a turntable preamp, vinyl sound will be very low and unclear.
Pre-Amplifier (General Use)
A general pre-amplifier is used in almost all audio systems to boost signals.
Features:
- Adjustable gain control
- Low noise amplification
- Multiple input support
- Stable output signal
Uses:
- Home theater systems
- Studio recording
- Public address systems
- Audio mixers
This is the most widely used type of preamp in audio systems.
RF Pre Amplifier
An RF pre amplifier is used in radio frequency systems to boost weak RF signals.
Features:
- High-frequency signal amplification
- Low noise performance
- Wide frequency range
Uses:
- Radio communication
- TV signal systems
- Wireless devices
- Antenna systems
RF preamps are essential for improving signal reception quality.
Pre Amplifier for Mic
A pre amplifier for mic is designed to boost microphone signals before sending them to mixers or recording devices.
Features:
- High gain support
- Low noise amplification
- Clear vocal enhancement
- Phantom power support (in some models)
Uses:
- Recording studios
- Live stage performances
- Podcasting
- YouTube content creation
This type of preamp is essential for professional voice recording.
How a Pre Amplifier Works
The working process of a pre amplifier is simple but very important.
Step-by-step process:
- Weak audio signal enters the preamp
- Signal is amplified using transistor or op-amp circuits
- Noise is reduced using filtering
- Output signal is sent to power amplifier or recording device
This ensures clean, strong, and usable audio signals.
Benefits of Pre Amplifier
Pre amplifiers offer many advantages in audio systems.
1. Improved Sound Quality
Enhances clarity and detail of audio signals.
2. Noise Reduction
Removes unwanted background noise.
3. Better Signal Strength
Boosts weak input signals effectively.
4. Compatibility
Works with multiple audio devices.
5. Professional Audio Output
Essential for studio-grade sound systems.
How to Choose the Right Pre Amplifier
Choosing the right preamp depends on your audio setup.
1. Application Type
- Microphone → mic preamp
- Vinyl → turntable preamp
- Radio → RF preamp
2. Signal Quality
Look for low-noise amplification.
3. Gain Control
Adjustable gain is better for flexibility.
4. Build Quality
High-quality components ensure better performance.
5. Budget
Choose according to your usage needs and price range.
