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 a 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 the tweeter.
• Separate Bass Control:
  Bass output is controlled separately. The bass lever lets you balance the bass to the highest. 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 mounts 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.

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 point in the frequency spectrum without 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 bandpass. The aux input with its own input gain controls allows 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.
