Build a Home Audio System Using Audio Amplifiers
Elan makes home audio components that interface to simplify how you use consumer electronics. Along with power amplifiers, the company manufactures system controllers and multi-room audio and video systems. There are several audio amplifiers available, each with distinctive features tailor-made for small and larger households.
What Are Some Notable Models?
- A12: Designed for multi-zone use, 12-channel power amplifiers have a power output rating of 30 RMS watts per channel. Moreover, the unit automatically detects audio signals and mutes and unmutes channels as necessary.
- A6: The most important component of a stereo system, the 6-channel amp is contained in one rack. A built-in bus mode makes setup easier as one input can be routed to three outputs. LED indicators on the front panel keep you apprised of voltage gain and signal strength.
- A2: Amps have gold-plated speaker posts to ensure solid connections and signal strength. The two-channel amplifier powers free-standing and in-wall speakers.
- D12: Designed for low heat and high-efficiency usage, the D12 amplifier uses Class D digital technology to create cleaner sounds.
What Specifications Are Important?
Power output is important when you use the equipment in larger rooms. Even the smallest two-channel systems crank out 150 watts per channel. Larger models produce 30 watts for each 8 ohms speaker. Likewise, these power amplifiers weigh between 18 to 60 pounds that adults can move by hand or a hand truck. Lower THD (total harmonic distortion) ratings range between minus 0.01 to 0.03 percent for the 6 and 12-channel amplifiers. Lower ratings indicate amplifiers output sound with less distortion and therefore purer sounds. Moreover, these amplifiers have higher sound to noise ratios between 95 to 110 Db to compensate for background noise.
What Features Should You Consider?
- Input Impedance: Most Elan models have an average rating of 47k Ohms to accommodate volume generated from several speakers.
- Number of Channels: If you have a smaller room, a two-channel system is adequate for your needs. Even if your current space is small, you can purchase a power amplifier with more channels. That way when you move to a larger home you can use the same equipment to expand your home stereo system.
- Easy-to-Use Controls: You should be able to glance at the amplifier and know instantly how it's performing. The controls on the amplifiers are located on the center front edge of each model.
