The PEX Five Hundred is a one channel transformer coupled Passive Pultec Equalizer. It’s an all discrete design based upon the great 990 amplifier.

The Equalizer is our take on the magical classic Pultec design. It’s got 15db boost of the creamiest high end you’ve ever heard and the most punchy low end heard in the 21th Century.

The PEX-500 fits in all 500 series compatible power supplies.

    ********************************************************************************************************************************* Issues with older BAE racks! Please be aware of that the older BAE racks uses 30-pin Edacs which is not 500 Series spec’d. You must bridge the pins on the back to make connection on both sides of the PEX-500 pcb. This is very crucial to get the power and i/o’s to work properly! If you have an older BAE rack or is unsure of the connection, please check the soldering of the Edac’s to XLR’s BEFORE POWERING ON THE UNIT! Thank you. ***************************************************************************************************************************
