In this post, I’m going to explain how digital audio connections work and also tell you why those connections are superior to using analog interconnects.

Almost a decade ago, a standard has been developed for transmitting audio in a digital format over signal cable. There are two types of cable for making such a connection. The first cable is a simple RCA cable which is also referred to as coaxial connection. However, there are also optical cables which transmit a similar signal by using light waves. There is actually a standard for the transmission of data is well as a standard for how the data is encoded.

Multichannel audio uses a different encoding standard than stereo audio. Therefore, when purchasing equipment, it is important to realize which of these standards is supported.

In terms of what kind of cable to …

One way of streaming music from a cell phone to loudspeakers is by using a Bluetooth amplifier. These units have Bluetooth reception as well as amplification built into a single unit which is usually quite small. However, one of the drawbacks of using such an integrated device is that the wattage is usually quite limited. This limitation stems from the fact that most of these Bluetooth receivers work with a fairly low supply voltage such as 12 V. As a result, when connecting speakers with an impedance of more than 4 ohms, the wattage is usually quite low because the voltage swing can be generated by the receiver is not sufficient to drive speakers loud enough.

Let me show you some ways for improving loudness in those cases. Obviously, the simplest solution is to purchase speakers that have a low …

If you have purchased an audio amplifier, it makes sense to spend a few minutes to figure out some key parameters of loudspeakers in order to purchase speakers which will work best with your amplifier.

One of the most important speaker parameters is the speaker impedance. The impedance is basically a ratio that determines how much voltage the amplifier needs to apply across the speaker in order to generate a certain amount of wattage. In other words, the higher the speaker impedance, the higher the voltage swing of the amplifier has to be in order to generate a certain speaker wattage. The speaker wattage will determine the loudness of the speaker.

Many small amplifiers work with an external power supply. If you look at the power supply label you will notice a voltage rating. The voltage rating determines how much …

In this article, I will offer some advice for setting up Bluetooth audio receivers. You can view this post as a tutorial. However, I will also offer some background information and highlight some of the features of different models of receivers.

I assume that you already are fairly familiar with the main purpose of Bluetooth audio receivers. There are a variety of Bluetooth receiver products on the market. These products differ in features and performance. Class I Bluetooth receivers offer a range of up to 30 feet. Class II receivers can offer a range of up to 300 feet. However, the wireless range depends a lot on your streaming device.

If you are Bluetooth streaming device such as your cell phone has poor transmission then even with a class to Bluetooth receiver you will not be able to achieve the …

In this post, I’m going to talk about a new wireless speaker that has been introduced by Amazon. This speaker is fairly smart and it connects to Amazon service. This speaker is called Echo. What is unique about the speaker is that it has built in microphones. As soon as you call its name which is Alexa this wireless speaker will start listening to user commands. Those user commands are then forwarded to the central server and are being processed. The result is that this wireless speaker will perform a certain action. The following actions are currently supported: the speakers able to provide simple information such as weather forecasts on use. This sort of information is typically retrieved from online radio stations. Also, it can also provide other simple answers such as the time of day, the date and other …

I used to be a professional installer for AV equipment for over 10 years. I do have quite a bit of experience when it comes to running speaker wires and setting up audio equipment. If you are planning to set up some speakers in your home or change the location of some loudspeakers, you every once in a while run into some difficult problems. In this post, I will offer some advice for solving these installation problems.

Admittedly, setting up audio equipment requires a special touch. Just imagine how upset your wife is going to be if you by accident drop your due LCD TV which may have cost thousands of dollars. Also, you need some experience when it comes to choosing the right audio and video components. Different types of audio equipment have different types of connectors and don’t …

Wireless speakers are usually easier installed then regular speakers. The main reason is that wireless speakers don’t require a connection to an amplifier. Instead, they need to be plugged into power. The signal is traveling through the air. Because wireless speakers already incorporate a power amplifier, you do not need any amplifier when setting up wireless speakers. Such speakers usually come with the transmitter base. This transmitter connects to any line out audio output. Such audio output is provided by almost any device such as a CD player, soundcard as well as DVD player.

So the first factor to consider when installing such speakers is to have an outlet near to the location of the speaker. The power supply which is provided with the speakers usually has a fairly short cable. If the power supply cable does not reach the …
