Locating a test point

Each of the following tracks produces a low-frequency test tone. The range of these tests is from 100Hz down to 20Hz. The frequency of each test is announced before it begins. The first test is the highest frequency (100Hz); therefore, you will be marking the template from right to left. Each frequency point is listed across the bottom of the Measurement Template (this is called the X-axis). See Figure 7 on the previous page. The vertical scale on the left side of the template indicates relative level, in dBs (the Y-axis). The template’s vertical scale matches that of the RSLM bar graph.

Cue Track 4 and Pause II.

From now on, you will want to keep your CD player’s remote control handy.

Press Play ▼. As Track 4 plays, observe the level indicated on the RSLM.

EXAMPLE:The test frequency is 100Hz and the level indicated is -2dB. Find the intersection of 100Hz (X-axis) and -2dB (Y-axis). Place a dot at that point. See Figure 8.

It takes a few seconds for the RSLM reading to stabilize, especially at very low frequencies. Don’t rush. Give each test adequate time for the meter to stabilize.

At the bottom of the bar graph is a green “ON” LED. This LED is illuminated whenever the sound level is below the measuring range of the RSLM. If this occurs during a test, place a dot at the intersection of the test frequency and the bottom frame of the template. See Figure 9.

When finished, press Skip▼▼ to advance to the next test. Repeat the process described above for Tracks 5 through 26.

When you have completed the 23 measurements, you are ready to analyze the data and make corrective adjustments. The completed Measurement template will look something like the example in Figure 10.

Now connect the dots as shown in Figure 11.

This will make interpretation of the data much easier.

1.2s specifications

The Infinity 1.2s is a revolutionary advancement in the world of audio technology, specifically designed for audiophiles and sound enthusiasts who demand superior sound quality. This state-of-the-art speaker system boasts a range of features that ensure impeccable audio performance, making it a popular choice among professionals and casual listeners alike.

One of its standout characteristics is its exceptional frequency response. The Infinity 1.2s is engineered to deliver a wide frequency range, allowing it to reproduce both deep bass and crisp treble with remarkable accuracy. This enables listeners to experience music as it was intended by the artists, with each instrument and vocal nuance clearly pronounced.

Incorporating advanced driver technology, the Infinity 1.2s features a combination of woofers and tweeters that work in harmony to create a balanced sound profile. The woofers are crafted from high-quality materials to minimize distortion while maximizing bass response, ensuring that low-frequency sounds are powerful yet controlled. Meanwhile, the tweeters employ cutting-edge technology to deliver high frequencies that are both detailed and smooth.

Another significant technology embedded in the Infinity 1.2s is the innovative crossover design. This sophisticated crossover network effectively divides audio frequencies between the woofers and tweeters, which enhances the speaker's overall performance by ensuring that each driver operates within its optimal range. The result is a seamless transition between low and high frequencies, producing a cohesive sound that is rare in many consumer-grade speakers.

The build quality of the Infinity 1.2s is also noteworthy. Constructed from durable materials, the cabinets are designed to minimize resonance and vibrations, which can muddy sound quality. This focus on sturdy construction not only enhances audio fidelity but also contributes to the longevity of the speakers.

Furthermore, the Infinity 1.2s is equipped with versatile connectivity options. It can easily adapt to various audio setups, whether wired or wireless, offering compatibility with a range of devices and systems.
