503HR 3-Space 500-Series

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.

We   have   been   asked   by   our   customers   to   develop   a   3-slot   version   in   a   horizontal   1RU   rack.   Well,   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.

Some   503HR   features   include:     All   metal   construction,   XLR   in   and   out,   as   well   as   a   “FEED”   switch   on   the  front.  This   allows   you   to   come   into   slot   1   and   out   slot   3.   It   also   allows   you   to   just   feed   1   and   2   or   none.  The  “Feed”   switch   is   a   3-position   switch   used   for:   Slots   1   and   2   or   “Off”   or   “All”.   This   reduces   the   need   to   use  six (6) XLR cables for a channel strip. But, if you are inclined to do so, you still have that option. When   using   the   503   with   the   “Feed”   switch,   all   that   is   needed   are   two   (2)   XLR   cables      -   Male   and   Female.  The   input,   as   an   example,   would   go   to   Slot   1   and   the   output   to   Slot   3,   when   the   “Feed”   switch   is   in   the  “ALL” position.

This   is   very   useful   for   live   applications.   For   example,   you   may   only   require   the   503HR   (with   a   500   series  Pre,    Compressor,    EQ),    a    power    amp    and    a    cabinet.    Place    the    “Feed”    switch    to    position    “All.”   The  connections   would   be   as   follows:   Assign   the   output   of   Slot  2  for  FOH  (Front  of  House)  and  the  output  of Slot  3  for  your  amp.  

Used  as  a  Channel  Strip  for  Bass  or  Guitar  [Preamp,  Compressor  and  EQ],  your  500 series  Pre-amp  would  go  into  the  500  series  Compressor,  Compressor  out  to  the  FOH  and  your  500  series EQ to your power amp then to your cabinet. This works extremely well.
