Heritage ZAPCO PX paragraphic Equalizer electronic crossover Old School RARE 

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 ZAPCO model PX is a programmable four-band equalizer and 12dB per octave electronic crossover housed in an attractive anodized aluminum chassis designed to be mounted either in- dash or under-dash. The PX is comprised of two pieces: the PX Main containing all of the audio circuitry and PSi, an isolated power supply that provides the audio circuitry with + or - 15V supply rails.

A master volume control and four filter control knobs are readily accessible on the PX front panel. The filter controls have a maximum boost or cut of 18dB at either extreme of rotation. Independent left and right channel INPUT GAIN adjustments are made via access holes in the lower left hand corner of the front panel. A main power ON indicator and three OVERLOAD indicators are provided to aid in system troubleshooting and calibration.

Signal inputs and outputs are made to the rear of the unit by way of gold plated RCA connectors. The back panel also contains the controls for the electronic crossover. The crossover frequency is continuously variable in a range of 70Hz to 1.6 kHz by using the CROSSOVER FREQUENCY control pot. Separate LOW / HIGH PASS OUTPUT LEVEL controls are provided for system balancing. An auxiliary FULL RANGE output is provided for possible use with full range satellites or 600 ohm earphone. The modular “phone” DC POWER INPUT connector at the upper right hand corner of the back plate is used to connect the PX Main to the external power supply, the PSi.

The power supply, model PSi, is a highly efficient and compact switching power supply that provides the PX Main with all necessary operating voltages. An extra modular output connector is provided for use with an additional PX. A fifteen foot interconnecting cable is supplied to allow for remote mounting of the supply. The PSi is used to trigger on/off operation of the PX Main. A plug-in barrier strip is used to terminate the necessary +12V, GND and TURN ON connections to the unit. 

 fully working tested all inputs and outputs are working.  sold as-is no return please check all the pictures for the item details

    Audi A2 planned for 2013

    Mon, 08 Mar 2010

    The original Audi A2. Audi are planning a new A2 for 2013 based on the A1 (adsbygoogle=window.adsbygoogle||[]).push({}); Well you didn’t really think that the kings of the car-niche would ignore the number 2 for ever did you? Despite the less than universal praise the original Audi A2 attracted (and, by Audi’s standards, miserable sales volume) they were always going to slip an A2 in to the mix somewhere.

The press conference at Detroit to unveil the new Tundra pick-up was littered with phrases beginning with 'biggest', 'most' and 'heaviest'. Welcome to the US truck market, where the ability to lug, tow and carry are more important than creature comforts or looks.

    Williams & Renault back together in F1

    Tue, 05 Jul 2011

    Williams Renault F1 - Sir Frank Williams and Renaultsport's Bernard Rey (adsbygoogle=window.adsbygoogle||[]).push({}); For those of us who enjoy F1 (on the whole – although races like Canada rather than Valencia, it as to be said) but are very slightly past the first flush of youth, it’s rather sad to see Williams languishing in the ranks of also-rans on this year’s grid. With one of the greatest race-brains in Sir Frank Williams, and still one of the best F1 drivers in Rubens Barrichello, it would be great to see Williams at least running with the second tier of cars. But this season so far they have amassed just 4 points.
