Having a radar detector and laser defense system in your car or truck is a great way to avoid speeding tickets. The success those systems have in helping you avoid tickets depends a great deal on how you use them. In this article, we’ll talk about laser defense systems and explain the Jam to Gun and Jam to Kill terms.

What Is a Laser Defense System?

Also called a laser or lidar jammer, laser shifter or laser countermeasure system, a laser defense system works to prevent a police officer from measuring the speed of your vehicle using a lidar (laser) gun. Because lidar guns can target vehicles very accurately (within a few feet at a range of 1,000 feet) and measure very quickly (often in less than 0.5 second), there’s no time for a driver to slow down once a detector has alerted him. Laser defense systems identify the light pulse pattern from the lidar gun, then transmit a signal that includes additional pulses that prevent the gun from working.

What Is Jam to Gun?

Imagine a scenario where you are driving at 90 mph in a 65-mph zone. When you are 1,000 feet away from the law enforcement officer, your laser defense system detects the lidar signal and starts jamming. In a scenario when you employ a Jam to Gun procedure, you allow the defense system to continue to transmit its signal and prevent the officer from taking a speed measurement.

The problem with the Jam to Gun method is that the officer will be expecting a measurement. When he or she doesn’t get it, they’ll know you are likely jamming the signal and may decide to pursue you in hopes of catching you speeding or doing something else wrong. You may have avoided the original ticket, but you may not get away without a fine.

What Is Jam to Kill?

A much better process is called Jam to Kill. When your laser defense system is triggered, you should slow down quickly but smoothly. You don’t want the nose of the car to dip suddenly, as that would attract attention. Once you’re at a speed that won’t attract attention, you can cancel the jamming signal transmission and allow the officer to take a reading. He or she may know what you’ve done, but without any proof that you were speeding, they will likely let you carry on your way.

React Quickly and Efficiently

If you are traveling at 90 mph, you are covering 132 feet per second. If the officer is 1,000 feet away, you have about 7.5 seconds before you are beside him. You need to respond quickly and efficiently to the laser alert from your defense system while not drawing attention to yourself. Several laser defense systems can be configured to automatically stop transmitting the jamming signal after a predetermined amount of time. Many users opt to set the system for 4 or 5 seconds. Others prefer to press a button to cancel the jamming signal once they know they are traveling at the desired speed.

For whatever method you choose, it’s worth practicing the process to the point that it becomes muscle memory. When the system triggers, check your rearview mirror, brake efficiently and smoothly, then cancel the jamming signal. Given that you’ll likely waste 0.25 to 0.5 second simply reacting to the signal, being good at completing the process is very important.

Protect Yourself with a Laser Defense System

If you find you occasionally (or frequently) exceed the posted speed limit, visit your local specialist mobile enhancement retailer and ask about having a custom-installed radar detector and laser defense system installed in your car or truck. Custom-installed radar detectors and laser defense solutions are something that you won’t want to try to install yourself as it typically requires the removal of the bumper covers and careful placement and alignment of the laser sensors for the system to function properly.

When it comes to recreating music in our cars, the weakest link in the chain will be the downfall of the entire system. Knowing this, if we start with the best recordings possible, the chances of our music sounding more realistic and lifelike increase astronomically. The equipment required to record, master and distribute high-resolution music helps to ensure that our mobile entertainment systems sound amazing.

What Is High-Resolution Music?

By definition, any music that is recorded with a bit rate (sampling rate) and bit depth (resolution) higher than that of a compact disc is considered high-resolution. This means 48 kHz and higher sampling rates and 24-bit resolution are required. Higher sampling rates capture some harmonic information, but transmitting and reproducing those sounds is extremely difficult.

Where Can I Get High-Resolution Audio Files?

Perhaps the best-known source for high-resolution music is hdtracks.com. This website rightly boasts that it has the widest collection of high-resolution music available. You have a choice of purchasing and downloading albums in AIFF, ALAC, FLAC and WAV formats at resolutions up to 192 kHz/24-bit as well as 2.8 MHz and 5.6 MHz DSD files. File formats vary by album.

Another popular source for buying high-resolution albums is Acoustic Sounds. Acoustic Sounds Super HiRez specializes in DSD format. The itrax.com website is another great source.

If you’re into streaming, you will definitely want to check out Tidal.com and Qobuz.com.

Why Should I Buy High-Resolution Music?

Some people will tell you that humans can’t hear audio above 20 kHz and that we don’t need more than 16 bits of resolution to accurately recreate a listening experience. Let’s say these statements are completely accurate. Why then would we want to buy high-resolution music? The answer is noise and accuracy.

The effort required to build a microphone that records to 40 or 50 kHz requires serious attention to detail. Capturing the upper end of the audible range is child’s play for products of this caliber.

The second benefit of high-resolution recording is a reduction in noise. This reduction comes from the fact that there’s an increased number of bits to work with (65,536 vs. 16,777,216) and the fact that the equipment used must be of a higher performance specification. Digital interfaces capable of working with high-resolution microphones from companies like RME, Presonus, Apogee and Focusrite deliver amazingly accurate digital conversions of the analog signal from the microphone. If you’re a numbers geek, as many of us are, here are some specs from the best studio-quality interfaces:

Frequency Response: 2 Hz to 92 kHz at -1 dB
Signal-to-Noise Ratio: 113 dB unweighted
Total Harmonic Distortion: <0.00032%
Channel Separation: >110dB

How to Reproduce High-Resolution Audio in Your Car

Buying great music is one thing, reproducing it in a vehicle is another challenge. Companies like Audison, Sony, Brax, Zapco and Kenwood all make audio components that will output or process high-resolution audio file formats. Of course, to hear that level of detail, you’ll need amplifiers capable of playing to at least 40 kHz and speakers with similarly impressive specifications.

Finally, and most crucially, how these components are integrated into your vehicle is also very important. To make the best use of the high-frequency information audible from high-resolution recordings, your tweeters will need to be mounted on-axis with the listening position or bounced off the windshield from a dash-mount location. If not, the directivity characteristics that are inherent in every speaker will make those sounds inaudible.

A Great Source Helps Ensure a Great Performance

If you’re passionate about your mobile audio system, drop by your local specialist mobile enhancement retailer today and ask them about upgrading your car stereo to support high-resolution audio formats like FLAC, DSD, WAV, ALAC and AIFF. We know you’ll be blown away by the accuracy and detail.
