A home theater receiver, also known as an AV receiver, is a device that provides you with inputs and outputs that you connect everything to.
A good home theater receiver combines an AM/FM turner, preamp control, and a built-in multi-channel amplifier, and as a result, gives you an easy and cost-effective way to centralize your home theater system.
When purchasing the device, you need to consider a number of things in order to buy the right one. Some of the factors you should consider include:
inputs and outputs
As mentioned above, the main function of the home theater receiver is to centralize your home theater system. Because of this, you want to make sure you choose a device with as many inputs and outputs as possible.
To get an idea of how many inputs and outputs your device should have, you need to count the devices you want to connect.
As a general rule, the catcher should have enough inputs and outputs to handle all of his equipment, as well as a few extra. This is to give you room for expansion.
Distortion
Since you will be listening to the receiver at high volume, you should always opt for one with low levels of distortion. You must remember that a receiver with a distortion rate of 10% at full power cannot be heard; however, a receiver with a distortion rate of 0.01% is excellent.
Many people tend to opt for receivers with powerful amplifiers and forget to consider distortion levels. Always remember that a receiver with a weak amplifier and low levels of distortion is more powerful than a receiver with a powerful amplifier and high levels of distortion.
To determine receiver distortion levels, you only need to look at the Total Harmonic Distortion (THD) specifications usually found on the back of the device.
AirPlay compatibility
Due to technological advances, it is advisable to opt for an AirPlay compatible device. The feature allows you to wirelessly stream music from an iPhone, iPod or iPad. The feature also allows you to stream music from digital apps like Pandora.
dynamic range
The receiver you want to buy should have the ability to double power for short periods of time to accommodate music spikes.
Dynamic range is measured in decibels. If a receiver has the ability to double power in a short period of time, it should have a 3db dynamic range.
