The Phoenix Audio DRS1R/500 is a mono pre amp and DI for the API 500 series.It was designed to be identical in terms of features and sonics as the ever popular DRS1 but in a new format.The unit runs at 24v thanks due to the special power supply built into the unit so it offers no sonic sacrifices whilst still maintaining a very low current use needed for the API format and is well within its API VPR limits.
