Your daughter is rocking out to every Britney song ever produced in her room, and the boys are cranking some horrible rap stuff in the game room. The best part? You have total control over what your kids are listening to, and how loud it is.

Easily access all of your music sources.

Like most people, you probably have music everywhere.  Multiple iPods throughout the house; hard drives, PCs or NAS drives with your digital music collections; stereos with your favorite local stations; and maybe even streaming music services like XM Sirius, Rhapsody or Pandora. It can be almost impossible to find that one, favorite song or figure out how to make a playlist using songs from different sources. we make it easy to access all of your music sources from one, central interface – and even lets you create playlists mixing any of the sources.

You don’t have to undertake a major remodeling project, knock down walls or start building a new house to enjoy the benefits of multi-room music. We simply connect Home Controllers, Speaker Points and Amps to your existing bookshelf or in-wall speakers and you’re in business. The system can easily access all of your music sources, giving you complete, intuitive control over your various music libraries.

Audio calibration

We provide complete set-up and calibration of Stereo, 5.1, and 7.1 audio systems using state of the art test gear. Through balancing, time alignment and equalization, your hardware and speakers will deliver every ounce of performance possible! Our audio calibration includes:

Channel Identification

This test insures all individual source channels are connected through your system to the correct loudspeakers. It usually consists of a standardized tone or voice that moves in turn between each speaker. Typical the order is front left, center, front right, rear right, rear left and sub woofer. Use this test to make sure each speaker is properly connected to the correct audio channel. There is nothing worse than a person moving to the left of the screen while the sound he makes moves to the right.

Polarity Test

Most good quality speaker wires are color coded in some manner; usually a stripe on one side or one wire silver while the other is copper color. The reason for this is polarity. Polarity simply put refers to the direction the speaker is actually moving. If one speaker is moving out while another is moving in there will be distortion and the sound waves produced will cancel out each other. Not a good thing. This test runs through pairs of speakers, usually in the order of LF/RF, RF/RR, LR/RR, LR/LF, LF/C. As you go through the tests if you hear one set of tones muddy or lower than the other check the color-coding of the wires to those speakers. This is also called a phase test.

Level Adjustment

Checks volume, level, loudness, and balance of each speaker in turn. This is done with something called, limited pink noise. Al you really need to know is pink noise is a non-specific noise that is produced in a standard volume. You want to hear the same level coming from each of the five main speakers during this test. You can get a sound meter from radio shack and set it for 78-85db C weighting and level response Do not set your system at maximum for this or any other test. Try to arrange things so that the dials are about in the middle of the range. For circular dials this means the little white indicator are all straight up in the middle of the dial.

Sub Woofer Level Adjustment

You may have just noticed that the sub woofer was not included in the above level tests. The reasons for this are that pink noise of a lower frequency is required to properly test your sub woofer. This test balances the audio level of the subwoofer to achieve flat and consistent response. Pink Noise of 20Hz to 80Hz is typically used. Set the volume to no more than 50% of the subwoofer’s range. This is also a phase test. The sub woofer should be set to about 3 Db lower than the other speakers in your system.

Noise Floor tests

Unless you have a professionally installed, acoustically perfect room there will be ambient noise in your home theater. Things like air conditioners, heaters, and the refrigerator in the next room all make noise. On most home theater receivers you can set the performance to accommodate for these factors. This test will run through a series of tones are a variety of frequencies, typically set for 1KHz, 4KHz, 8KHz, 250Hz and 63Hz. In this test you lower the settings on your amplifier or receiver until you can no longer hear the test tone. This test provides the optimization of the dynamic range of your system. Dynamic range is defined as the difference between the loudest and lowest signals your system produces. Technically speaking various third octave band limited pink noise is used.

Rattle Test Sequence

The last of the common audio to consider is one that makes sure your new home theater will not shake the room and everything in it. While many people think a well functioning home theater should emulate a 5.5 earthquake this is not the case. Such vibrations are not only distracting; mask the real audio content of the film but it can damage your equipment. This test goes through each speaker in turn with several frequencies. The test locates objects in your room that will vibrate in response to your speakers. It also tests for speaker rattle. Various swept sine waves are used for this test. Sympathetic vibrations in your room and equipment will be produced so expect things to shake a bit during this round of testing. Because this test can get loud be conservative in the settings on your system. The frequencies used can be harmful to small children and pets so keep them out of the room and make sure you don’t push your system to the point where your hearing is affected.

Just a last note about using these calibration discs, it is not uncommon for your equipment to come out of the box set incorrectly. Most manufacturers set their systems to sound great in a show room where the acoustics are typically much brighter than the average room in a home. The most incredibly designed piece of testing equipment anywhere is your ears. Learn to trust them. You spent the money on this system and it should be up to your standards of what sounds good, not some group of people in white lab coats in some testing facility. Use these tests as a base line to start. Set things for how you like them. These discs help you make these decisions; they should not be used to make those decisions for you.
