ASP-Q1   Dash Mount EQ with 3-Way Crossover

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.


A Full-System Preamp for people who are serious about sound quality!
Here is an Equalizer/Preamp worthy of the Zapco name. The ASP-Q1 was not designed to be an “accessory” toy or a piece of jewelry for the dash. The ASP-Q1 was designed to be an effective tool in tuning and controlling the sound of a car audio system. As a dash mount equalizer it is unmatched. With 5 bands of parametric equalization you can put up ±18dB of correction at any points in the frequency spectrum with out being limited by fixed center points. With audiophile grade internal components in the signal path and precision pots for all adjustments the sound will be clean and transparent, with rock solid bass and crystal clean highs. The ASP-Q1 excels as a crossover as well. You can configure a 2-way with bass and dual highs or as a 3-way crossover with a band pass. The aux input with its own input gain controls allow a portable source to be plugged in and level matched to the main input.  The over-sized power supply gives you  a 9.5 volt line driver with 14 volts available for peaks. This gives the ASP-Q1 plenty of headroom so even on the biggest signal peaks you amp will get a clean distortion free signal. The ASP-Q1 is more than just an Equalizer. It is a true control preamp for your sound system.

    •    Five bands of Parametric Equalization: Since no two cars are the same, there is no way  for us to know  exactly where the center points need to be in any particular car. The ASP-Q1 lets you vary the center point of each of your 5 EQ bands to put the correction exactly where you need it to custom tune your system to your car.

* Variable 18dB/octave electronic crossover: There are 4 crossover filters on the ASP-Q1. You can only 3 filters to configure a 2-way system with a sub woofer and front and rear speakers with high pass or full range and fade front to back from the EQ. You can also use all 4 filters and confiigure an active 3-way system with a woofer, a band passed midrange, and a high pass for tweeter.

* Separate Bass Control: Bass output is controlled separately. The bass lever lets you balance the bass to the highes. As well as the crossover filter for the bass there is a bass phase control to adjust the phase of the bass signal from 0 to 180 degrees to help align the bass wave to the rest of the system.

* Auxiliary input: The ASP-Q1 has an auxiliary input so you can play from another in-car source ro from a portable player.

* Input gain controls: Each channel of both main and Auxiliary input has its own input signal adjustment.

* Balanced/Unbalanced Inputs: The ASP-Q1 can accept either balanced inputs, with a Bal/UnBal switch for Main-in and Aux-in.

* Tiffany style panel mount RCA connectors: These give positive, trouble free RCA signal connection

* High voltage power supply: The ASP-Q1 has a remote high voltage power supply for or a true 9.5 Volt RMS preamp output.
