ASP-L2T   2-Channels Line Noise Filter

Analog Signal Processors

In 1978 Zapco introduced the world to audiophile signal processing with the iconic Zapco PEQ 18 band equalizer. It was the first high output processor for the car. With high grade “mil-spec” slide pots and internal components, the SEQ showed the industry what in-car sound processing should sound like. The SEQ was followed by a series of audiophile quality processors including the first parametric car EQ, innovative electronic crossovers, a 30 band mono EQ, an advanced noise gate, and even an outboard D/A converter that surpassed most home D/A converters.
Now, when most head units and amps have processing built in, Zapco continue to offer audiophile quality outboard processing.
For many people“OK” sound is just fine as long as it’s quick, and easy, but Zapco makes processors for those who want something better.
We make processors for those who think that the live musical experience is worth the extra effort. We make processors for those who think that the sound is what matters most. If you want to sit in your car and feel like you are right there, in the audience, at the concert hall...
Zapco makes processors for you.

The legendary Zapco Analog Signal Processors are back

Zapco analog processors are legendary for both sound quality and reliability. Zapco processing started in 1978 with the famous PEQ, 9 band, dual channel control, preamp EQ. With balanced inputs, high voltage outputs, and military grade internal components, the PEQ was the first true Sound Quality EQ for the car. The PEQ was followed a few years later by the Zapco PX. The PX was the first parametric EQ for the car. With high voltage inputs and outputs, an 18dB electronic crossover, 4 parametric EQ bands, and a noise free remote power supply, the PX became the competition EQ for the 1980s. The 90′s brought the Zapco SX series of EQs with Zapco parametric equalization, high voltage outputs, fader, and bass to highs balance control. The SX became the new top dog of the competition circuit. Then Zapco led the pack into digital processing in 2004 with the famous DSP-6 and the DC line of amplifiers.
But we know that vinyl records continue to be preferred by audiophiles over CDs and other digital media for one reason. The purity of the sound. Many aficionados of great sound prefer analog processing over digital for the same reason. Analog reproduction of music continues to have a warmth and sonic purity that is lost in the digital realm.
Now Zapco brings you the new family of Zapco analog processors. Zapco processors are designed and built for the audiophile ear. These processors use top end Elna Silmic ll capacitors throughout the signal path. The op amps are the Analog Devices  op275s, and we went straight to factory who builds the best precision potentiometers around, and had our own custom pots built for these new processors. Each of these processors is designed to do one job and to do it right. There is an audiophile EQ for the dash. There are 2 electronic crossovers, 2 signal line drivers, and OEM line adapters for upgrading factory stereos. These processors are all designed for maximum versatility to give you exactly what you need to get the most from your sound system. And they have quality touches to go a step beyond. The ASP-Q1 in-dash EQ has a copper chassis for maximum noise rejection. The larger units use a remote power supply to keep the high voltages out of the main chassis, and for maximum reliability, the under seat and trunk mount units have a plexi cover plate to keep dust and dirt out of the units after you’ve made your settings.
So; If what matters to you is music…if sound is not just the main concern but the only concern...
If you want your system to put you front row center…
Zapco makes a signal processor just for you.

Solution 1977 to 2106: The ubiquitous Ground Loop Isolator has been to "easy" answer since the mid 70's. The good news - the Ground Loop Isolator does indeed work to eliminate the ground loop noise. The bad news - the Ground Loop Isolator destroys the signal by acting as a high-pass filter and eliminating bass frequencies. It also adds multiple layers of distortion to the signal.  Why does the old Ground Loop Isolator damage the signal? Because it was designed ONLY to stop the noise with no thought to signal quality.  Low cost, low efficiency components were combined to provide  a low cost "quick fix" to the noise problem. So for all these years installers have used the old Ground Loop Isolator as the last resort when they don't have the time (or possibly the ability, depending on the equipment) to solve the grounding problems. They have been forced to sacrifice signal quality to stop the noise.
Solution 2017: Zapco introduces the ASP-L2T signal noise eliminator. The ASP-L2T utilizes custom designed and custom wound high efficiency transformers and other high SQ components to remove the direct connection between the different reference ground systems and eliminate noise,  without affecting the bass content of the signal and without adding distortion into the signal.
Performance: Signal to Noise is over 130dB, and  THD+Noise is less than 0.1%. Signal level and impedance of the output are exactly the same as the input, and the frequency response of the ASP-L2T will even exceed the response of the input signal from the head unit. In fact the ASP-L2T can even be considered a "conditioner" to improve the signal from the head unit before it arrives at the amplifier. Maximum performance upgrades occur between 500mV and 1 Volt.
