Understanding Amplifiers
NAD Electronics- Stereo Integrated Amplifier NAD C350
An Amplifier is an externally powered circuit that generates an output signal that replicates its input to give a stronger signal. Simply put, the primary function of an amplifier is to increase the volume of a speaker’s voice for audibility.
It is used in wireless communication, broadcasting, and audio equipment, ensuring the signals are not entangled between circuit parameters.
Types of Audio Amplifiers
The various kinds of audio Amplifiers include;
- Class A amplifiers have output transistors that remain conductive regardless of the output signal waveform.
- Class B amplifiers use a push-pull configuration where the output includes both positive and negative transistors.
- Class AB amplifiers are made out of a combination of the sound quality traits of Class A amplifiers with the efficiency of Class B amplifiers.
- Class D amplifiers generate a digital output signal by utilizing pulse-width modulation. By fully turning the output transistors on or off, Class D amplifiers achieve high efficiency while eliminating the inefficiencies associated with other amplifier types that rely on the linear region of transistors.
- Class G amplifiers employ multiple supply voltages. Class G amplifiers operate with a lower supply voltage at low signal levels. As the signal level increases, they automatically switch to the appropriate higher supply voltage.
- Audio Frequency Amplifier – which increases signals in the range of human hearing. This is usually not such a high-frequency amplifier. For example, Microphones and Disk pickups use this type of Amplifier.
- Direct Coupled (DC) Amplifier – amplifies an alternating signal that changes slowly with time. For instance, a DC Amplifier is found in many electrical control systems for big mainstream media companies and music recording studios.
- Video Amplifiers – are a particular type of amplifier that generate specific signals that apply to the video equipment used. This means that the Amplifier carries all the picture information on TV sets, video, or radar systems such as CCTV to clarify a picture better.
Pros and Cons of Using An Amplifier
Whether at home watching your favourite program or listening to music while driving to work, having an amplifier has both its highlights and lowlights.
Pros of using Amplifiers
- An amplifier enhances sound quality; Serving as the primary power source for your speakers, it ensures optimal performance and prevents strain on the speakers. This enables them to function correctly and deliver the best possible sound quality.
- An Amplifier provides ‘plus’ volume; It helps you hear your audio by increasing loudness over noises such as traffic or a loud motor.
- It acts as power for speakers and subwoofers. Subwoofers demand more power compared to standard speakers.
- The amount of charge in an Amplifier is not affected by the capacity of a cable present.
Cons of using amplifiers
- An Amplifier can overheat due to its large power supply. The heat can cause damage not only to itself but also to other connected equipment in its vicinity.
- Amplifiers are expensive; thus, they are available for specific markets that can afford one.
- Electromagnetic Interference generates foul feedback by the Amplifier. For example, a phone ringing close to the amplifier results in negative glitches and sounds from the Amplifier.
- Direct-Coupled Amplifiers do not amplify high frequencies since they cannot sustain such voltage levels for an extended duration.
Understanding AV Receivers
MARANTZ Receiver 2285B
An audio/video receiver (AVR) is a consumer electronic component whose purpose is receiving audio and video signals from numerous sources, processing them, and routing them to displays such as Television or video projector. It is an Amplifier on steroids. With A/V receivers, its basic functionality is to receive an audio signal, amplify it to drive multiple speakers, and allow pass-through of the video signal to a display device.
Components of an AV Receiver
- Power Output – the power ratings of a speaker dictate the kind of receiver one requires.
- Video Inputs – AV receivers feature an HDMI component and composite inputs that help in video signal connectivity.
- Audio Input – an Av receiver accepts audio from various sources, such as analogue stereo inputs. Additionally, many of them feature jack cables for AUX connectivity or basic karaoke sessions.
- Multi-channel speaker outputs.
Initially, the receiver has an inbuilt capacity that combines multi-channel sound processing, audio-visual swapping, and synchrony in one framework.
An example of an AV Receiver is the Yamaha RX-V685, considered an all-in-one system.
Pros and Cons of Using an AV Receiver
Quality Audio-Visual content is achieved through upscale technology supporting its counterpart in providing the desired product.
Pros of an AV receiver
- A receiver brings simplicity. A receiver gives simple connectivity because the user does not need all the complex wiring between devices.
- Efficient Space. A Receiver takes up much lesser space due to its small size and, thus, is easy to move around and maintain.
- It provides sufficient power to drive many speaker systems.
- Yearly recycles – a new receiver model comes with updated technology.
- A Receiver provides a more desirable value, thus cost-effective to most people.
Cons of an AV receiver
- Limited power supply – It does not give adequate clean power required to run the system.
- The space limits performance – its performance depends on the size of the room. For instance, a receiver in a small room performs better than one in a spacious room due to the vacuum space.
- Low effectiveness compared to a good amp. A receiver may fail to offer equal performance as that of a good amp.
- Performance constraints – an A/V Receiver can limit performance, especially if paper rating and manufacturing specs differ.
Key Differences between An Amplifier vs AV Receiver
Here are some of the differences between the two;
- A Receiver has a built-in radio section, while an Amplifier is just a device taking the audio signal and amplifying it for speakers to play the audio.
- The number of channels differs – an AV Receiver comprises 4-9 or up to 11 channels, while Amplifiers only have two channels when playing.
- Different sound atmosphere – the AV Receiver focuses on creating a sound field and simulating the atmosphere in a listening environment. In contrast, an Amplifier focuses on amplifying the signal emitted by the signal source.
- Different parameters – While the Amplifier emphasizes its harmonic distortion and signal-to-noise ratio parameters, the AV Receiver uses the same parameters but also includes the output power and the frequency range parameters.
- Passive speakers, which cannot be powered independently, use an Amplifier, whereas an AV Receiver is suitable for both passive and active speakers.
Amplifier vs AV Receiver: Making an Informed Decision for Your Sound System
So, what should you consider when choosing your sound system?
- Consider the type of home sound systems available for you. Some common types to consider may include; Floor Speakers, Subwoofers, and Portable speakers.
- The difference between surround sound and sound bar. Surround sound systems disperse the sounds in a room to give a cinematic experience. In contrast, Sound bars are thin subwoofers that fit in smaller spaces like your car’s interior or the house’s television set.
- Your sense of space and acoustics. Ideally, examine the rooms you are using for your entertainment purpose and align the acoustics with your choice of sound system.
- The right place to purchase one. Today, many stores are focusing on selling only audio equipment and speakers. It is essential to narrow down your options, compare and consult experts, finalize a model, and identify the best dealer to purchase your sound system from.
- Budget: Set a budget for your sound system. Based on how much you are willing to spend, prioritize your selection accordingly. Investing in higher-quality components often results in better sound reproduction and longevity.
