What Factors Affect The Sound Quality Of PA Systems In Small Auditoriums?

A public address system (PA) is a sound reinforcement system consisting of microphones, amplifiers, and speakers. The audio equipment is configured to allow people in a given venue to hear the speeches and music coming from the stage. The signal for the speakers may be derived from multiple sources, including a mixing console, signal processors, effects units, or a combination of these.

So, to build a complete PA system for a small auditorium, the following are the main components:

  • A power amplifier that has enough power to drive all your speakers. The more channels it has and the more powerful each channel is, the better. You can use 8-channel amps if you need more power or 4-channel amps if you don’t have many speakers to power.
  • Speakers with good sensitivity and low impedance can be driven easily by the amplifiers. Also, they should have good frequency response and low distortion at high volume levels (for which we recommend using high-quality speakers).
  • You will need an equalizer – by default, most amplifiers come with built-in EQs so this can be skipped or used as a backup option if needed.
  • You will need an audio mixer. This is optional as well but it helps to keep all your inputs separate (microphone inputs, instrument inputs). And it makes it easier to adjust everything from one place.
  • Microphones are used to pick up sound from the surrounding area and convert it into electrical signals. This can be done by using a diaphragm or ribbon mic. A condenser microphone is more sensitive than dynamic ones so they are better suited for larger rooms.

This blog mainly introduces the power amplifier. It is not only the heart of the PA system but also helps other equipments play a better role.

What Are The Amplifiers? And What Kind Of Power Amplifier Is Best For Small Auditoriums?

Amplifiers are electronic devices that increase the power of an electrical signal. They are also called power amplifiers, although power is not their only function. The term “amplifier” has been used for decades to describe many types of electronic devices and circuits that do everything from increasing the volume on a radio to producing high-resolution sound in a recording studio.

The types of amplifiers:

Amplifiers come in two basic types: solid state and tube, which are different in how they work.

Solid State Amplifiers:

Solid-state amplifiers are those that use transistors to build the audio circuitry. They are often more efficient than tube amplifiers and have less noise. These amplifiers are generally more reliable and durable than tube amps, but they do not produce as much warmth or distortion as tube amps, which can be a benefit or a drawback depending on the application. Solid-state amps also tend to cost less than tube amps of similar power output.

Solid-state amps are generally easier to maintain and repair than tube amps, which makes them a good choice for rental applications where maintenance may require some expertise.

Tube Amplifiers:

Tube amplifiers usually have a warmer sound than solid-state amps, which makes them ideal for jazz and blues music. Tube amplifiers also tend to have more distortion than solid-state amps, which can be desirable in certain genres of music (such as metal). Tubes also tend to be less reliable than transistors due to their tendency to fail over time (which is why they’re no longer used in most consumer products).

Which ones are more suitable amplifiers for small auditoriums?

For most people, solid-state amplifiers are preferred. Solid-state amplifiers are the most commonly used in small auditoriums. The reason for this is that they provide better sound quality and have longer life spans. They also consume less power compared to tube amplifiers which means that you will be able to save on your electricity bills.

Tubular amplifiers were once very popular but they are now considered obsolete because they produce more heat than solid-state amplifiers and they require regular maintenance in order to keep them running properly. If you own a small auditorium, then it would be better if you purchased a solid-state amplifier instead of a tubular one since it can last longer without having to undergo extensive repairs or maintenance.

How Many Amplifiers For Small Auditoriums Is Better?

If you plan to build a new small auditorium and equip it with a professional PA system. You can size the auditorium according to the type of performance and the size of the audience you plan to accommodate. Before making a decision, you need to confirm a few things:

First: How big is your small auditorium?

The size of your small auditorium determines the number of people who can attend your event. For example, if your small auditorium can accommodate 50 people, then it’s enough to use one amplifier. However, if it can accommodate 500 attendees, then two or three amplifiers will be required.

Second: How many people can it accommodate?

This has been answered above but it merits repeating because it is so important! If your small auditorium can accommodate only 100 people, then one amplifier will do fine for you. But if it can accommodate 500 attendees or more, then two or three amplifiers will be necessary for optimum sound quality and volume levels.

Third: What kind of event are you planning to host in the small auditorium?

Is it a speech or a cabaret? Will there be a band performance? Will there be any audience participation? If so, how many people will attend?

If it’s just one person speaking in front of an audience, then you don’t need that much power. However, if there will be background music playing during the entire event, then you would need more power.

Also, if there will be no audience participation but there will be some interactive parts like video conferencing or presentations, then again more power will be needed. This means that you need to know what kind of event will take place in order to buy the right amplifier for your small auditoriums.

Do More Powerful Amplifiers Sound Better?

When it comes to amplifiers, there’s a myth that more power equals better sound quality. But this is not the case. In fact, the best sound quality comes from amplifiers with a very high wattage rating, but which are driven at very low levels.

For example, if you have a 100-watt amplifier and you’re pumping it to its max volume, then yes, you’ll get distortion — because it’s too powerful for the load (the speakers) and they can’t handle all of that power being sent to them. But if you have a 100-watt amplifier that’s being run at 10 watts? Well, now you’ve got a great-sounding system!

The key is matching your speakers with an appropriate amplifier. For example: if you have 3-ohm speakers and want to use an amp with only 4 ohms of impedance, then you’ll need an external crossover network or subwoofer amplifier to divide up the signal so that each speaker gets what it needs from the source signal (which will be twice as loud).

So do not buy more powerful amplifiers just because they’re cheaper or because they look cool. Buy them because they fit your application and give you good value. 

If you want some amplifiers for small auditoriums, definitely don’t forget to buy proper speakers. Because, if the amplifier is the engine of the car, then the speaker is the tire of the car. It is impossible for any car to start normally without these two things.

You can go to a reliable company, such as GEDI-G, and ask for responsive amplifiers and speakers, and they will give you professional advice.

How Do Amplifiers Affect Sound Quality?

Amplifiers are an essential component of any PA system. They increase the voltage of your microphone or instrument, which in turn allows for a stronger signal to be sent over long distances. But how does this affect the quality of your sound?

Increase the power handling capacity of the loudspeakers:

They increase the power handling capacity of the loudspeakers so that they can handle louder signals without distorting them. This is important for situations where you need to play at high volume levels or for longer periods of time.

Improve the SN ratio:

They improve the signal-to-noise ratio (SNR) of the amplifier, which ensures that noise from other devices in the system does not interfere with audio reproduction. The higher this number is, the better your system will sound when compared to systems with lower SNRs.

Reduce distortion:

They allow you to reduce distortion by enabling you to select a higher damping factor (DF) setting on your amplifiers, which helps protect against thermal compression and speaker damage from overdriving them with too much power.
