A Designs Audio introduces the 503HR horizontal, three space, 1RU rack for the 500 Series (Lunch Box) crowd. The 503HR is replacing the A-Designs 500HR two-slot, horizontal rack to accommodate the increasing need for Channel Strips in both recording and live application fields. A Designs have been asked by their customers to develop a 3-slot version in a horizontal 1RU rack, the end result is the 503HR. We feel this meets the need for a full-blown Channel Strip, a requirement for Pro Audio Recording and live applications for performing artists that wish to adapt their sound for changing venues. This can be accomplished by using a simple insert of a different module (or two, or even three).

The 503HR has a robust external power supply with an LED display. This displays the amount of power being consumed or if the units in the 503HR are drawing too much power. But, the robust power supply can handle the demand. There is a 3-LED array on the face plate which displays the +16V, -16V and +48V.
