Zapco

Size guide

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 clear 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.

Features and Functions

• 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 subwoofer 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 configure an active 3-way system with a woofer, a band passed midrange and a high pass for a tweeter.

• Separate Bass Control: Bass output is controlled separately. The bass lever lets you balance the bass to the highs. 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 or 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.

Zapco Studio-D amps put big power in a small chassis. But these little beasts aren’t just small, and they aren’t just powerful. They sound great! They had to earn the Zapco name before we put them into production. These amps are loaded with all the advanced features you would expect…and more! They have crossovers, bass boost, both RCA and Speaker level inputs, and preamp outputs to send the signal to another amp. The three larger chassis ST-D amps also have a dash remote control. Finally, the ST-D amps have Bluetooth Streaming, so your Smart Phone, iPad, or other Bluetooth devices can be a portable music source for your sound system.

When the Studio D BT amps are installed they work just like any other amps with your head unit. But if you fire up the music on your

phone, tablet, or other Bluetooth smart device, these amps will automatically switch over to Bluetooth to grab that signal.

In 2015, if you want the best sound and all the dynamic range your system is capable of, you need a signal line driver.

In the ’90s, any decent deck had 4 volts of preamp output. Some had 8V and some even had 12V.  But now, even the best units have only 4V RMS and most are barely 2V, and that’s 2 volts only at 1KHz at clipping. Ask the deck to produce preamp voltage at all frequencies (like when you’re playing music) and that voltage drops by 1/2 and often even more. `

What does this mean to you?  First, when you have less signal going down your RCA cables you need to gain your amp up to get volume and then your system has more background hiss and likely more distortion. An even bigger tragedy is that you are compressing the dynamic range of the music. You lose the difference between the quiet and the loud and the music sounds “canned”. There’s no life in the music.  What’s the answer? A Zapco Signal Line Driver Preamp. The ASP-L2 BT is a true 9.5Volt output line driver with 14Volts peak. The ASP-L2 has a single pair of inputs, but it has 2 pairs of outputs so you can run both a bass and a highs amplifier off the same preamp output. And, of course, each output signal gets 9.5Volts RMS.

Bluetooth Streaming: The ASP-L2 BT is not just an awesome 9.5V RMS line driver. It is also a Bluetooth input for your sound system. The L2 BT also comes with a dash remote level control so you can match the level of your Bluetooth device and the level of your head unit and use the L2 BT remote as your system volume control.

Let us take it a step further: If you do most of your listening to on an iPod, MP3 player, or other Bluetooth devise, why do you need a head unit? Really, when you have an ASP-L2 BT line driver you have your Bluetooth input, your signal line driver, and your volume control. So the head unit becomes the optional accessory! You don’t need a head unit if you don’t want one. If you have a motorcycle, boat, classic car, hot rod, 4-wheeler, or side by side RV, you probably don’t want to have to put a head unit in the vehicle. The ASP-L2.BT is exactly what you need.

Two years ago, Zapco introduced the new DSP-Z8 IV signal processor. It was designed to bring true audiophile sound quality to an affordable DSP. And it did just that! The DSP-Z8 IV provided sound quality superior to units costing even twice as much. Even competition cars are using the Z8 IV, right up to one of the top Master Class SQ cars. The DSP-Z8 IV has been a true giant killer. But, as we have always said, and always will say, “We believe we can still do better”. This year we present the Zapco DSP-Z8 IV II and the ADSP-Z8 IV-8 Amplifier. What’s new with the Series IV II? Just about everything, new form, new features, new control... even improved sound quality with a lower noise floor.

The sharp new look matching the Black and Copper theme of the AP amplifiers is only the beginning. The hardware inside is where the magic begins. A quick fact: You can only be as good as your source material, and the DSP-Z8 IV II series greatly expands your potential for the best possible source material. The Toslink optical input accepts the digital signal from your head unit or from a portable HD player, but the IV II series doesn’t stop there. The DSP-Z8 IV II units also have digital Bluetooth streaming so you can stream digital music.

In 2012 Zapco introduced the new Z-Series of SQ amps. These amps were not conceived so much by our engineers, as by input from audiophiles and car sound fanatics around the world. We experimented with internal components and new circuits to see if we could take our amps to the next level of sound quality by investing in different internal components and circuit designs, and the resulting Z-Series amps were the results of this unique development method. 

This year we stepped back and took a look at the amp that started it all. The Z-Series amplifier. We knew we could bring the price down, because over the last few years. This allowed us to build the Z-series AP and SP amps cost only a little more than the original Z-Series so the prices weren't that far apart. Now we have brought the Z-Series into the same plant as the newer models. That lowers the price, but what could we do the make it better? We saw that a lot of the non-critical parts from the AP and SP amps could be used in the new Z-Series as well. Even with some of the SQ parts we save by buying more so, we can use those in the Z-series also.

In 2011 Zapco produced the new Z-Series Competition amps, and the response was incredible. Testers thought it was our best work ever and the new amps were snapped up by sound-off competitors around the country. With the new Z-Series SP, there are now four Zapco Competition series products based on the same amplifier. The Z-AP, the Z-SP, the Z-II, and the ZX amplifiers. The specifications of the Competition series amps don’t change but each is tweaked to a specific purpose. 

A purpose-built competition series amplifier is the Z-SP amplifier, as in Super Power or Street Power. This series comes from the need to outfit cars that compete in the new category called “Street Challenge” in some competitions it’s called “Street Demo”.

What is “Street Power”? Literally, amplifier power for the Street; an amplifier that will be used on the street, in the open spaces, with the door open, and cranked up for all to hear. 

If you want competition level sound quality and want to blow the doors off at the same time, these are your amplifiers.

In 2011 Zapco produced the new Z-Series Competition amps, and the response was incredible. Testers thought it was our best work ever and the new amps were snapped up by sound-off competitors around the country. With the new Z-Series SP, there are now four Zapco Competition series products based on the same amplifier. The Z-AP, the Z-SP, the Z-II, and the ZX amplifiers. The specifications of the Competition series amps don’t change but each is tweaked to a specific purpose.

Audiophile: An audio fanatic whose sole passion is the accurate sound reproduction that brings all the purity of a live performance to recorded music. It is a familiar term with high-end home gear like McIntosh or Bryston, but a term always considered unattainable in the automotive environment. Zapco disagrees! In 1974 Zapco began a quest for perfect sonic reproduction. While perfection may be unattainable, the quest is no less worthy. In 2000 we introduced the C2K Competition amplifiers and in 2012 we introduced the new Z-Series amps with high-end internal components matched for pure sound quality.

This was our first line developed by listening rather than by measuring, and they were called the best Zapco ever. How did we respond? We said “thank you, but we think we can do even better”. And we did. We upgraded to top end audiophile caps and op-amps, redesigned the power supply, and made board modifications to create the Z-Series LX amps. Not only did they top the car audio comparisons, but home speaker makers even brought their speakers to our CES suite to demonstrate what their speakers could do. The LX was beating their demo home amps in sound quality. How did Zapco respond? We said, “thank you, but we think we can do even better”.

And we did! This year we built an amplifier to set new sound quality standards for both home and car sound reproduction. The Z-AP Series.

While sound quality is always the number one factor in a Zapco design, there are other factors in the Studio design that make them "every-day" amps. The extruded aluminum chassis is more compact and lighter to make the studio series an easier fit in today's smaller cars. The feature set of the Studio amps provides you with all the system versatility you need without adding additional components, with everything from crossovers to preamp outputs, so multiple amps don't require extra signal cables. Power, price, size, and performance.

No, it's not designed specifically for competition. This is an amp designed to knock your socks off... in your car, for your daily use, every day. So go ahead... pop in your favorite disk, grab the volume control, and see if you don't agree that dedication to sonic purity is definitely a good thing.
