ASP-OE2   OEM Speaker Level to Preamp with Bass Recovery

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.


It’s difficult at best to change many factory head units. In addition there are any number of features and functions that are hampered or lost if the factory head unit is removed. The ASP-OE2 is an OEM adaptor designed for superior sound quality, with top end internal parts and Zapco’s custom built high precision pots. It is an active device including the line converter and a signal line driver that puts out 9.5V RMS and 14V peak signal voltage. With the ASP-OE2 your system will sound every bit as good with the factory head unit as it would with an aftermarket head unit.
Bass Recovery: If you are driving a fairly new car, you’re probably noticed that when you turn up the volume of the system the bass seem to drop out. That’s because the auto makers are actively equalizing your system. They do think to protect the the factory speaker from the damage when you crank up the volume. Well, even when you add amplifiers and speakers to the car, that factory head unit will still pull out the bass frequencies when you turn up the volume. One way to avoid the bass loss to leave the volume range of the head unit low and turn the gains of the amps way up. That way the head unit does not know how loud the system is.  Unfortunately this does terrible things to the sound. You can go here and we explain all about the factory roll-off and how the ASP-EO2 cures it. But for now, the important thing is that the OE2 can seamlessly put the bass back ino the systen regardless of the head unit volume control.
With the ASP-OE2, you can leave the amp gains down and get crystal clear mids and highs and rock solid bass from the factory head unit at every volume from quiet conversational back ground to setting-off-the- neighbor’s-alarm, ground pounding loud.
