Balanced    inputs    and    outputs    respectively    are    3-pin female    and    male    XLR's    at    the    rear.    The    unbalanced inputs   and   outputs   are   available   at   both   the   front   panel (RCA's) and rear panel (3.5mm stereo mini-jacks). There   are   internal   jumpers   provided   for   pin   2   or   pin   3   of the   XLR's   to   be   "Hot"   (+ve   phase)   and   the   input   and output    screens    of    the    XLR's    may    be    disconnected. Factory defaults are pin 3 Hot and screens grounded. The   balanced   output   levels   automatically   compensate   if either   pin   2   or   pin   3   of   the   XLR's   are   connected   to   pin   1 (ground). Sufficient   gain   and   attenuation   are   provided   by   the   front panel   multi-turn   adjustments   to   cope   with   the   highest   and lowest common audio levels. The   headroom,   frequency   response,   noise   and   distortion specifications   are   impeccable,   making   the   AB2C   audibly transparent in the audio chain. Three   units   will   fit   side-by-side   on   most   rack   trays   or   on top    of    other    rack-mount    equipment.    The   AB2C's    front panel is 1RU high. Mains   supplies   of   240V   &   120V   50/60Hz   are   catered   for and a 12-24Vdc version is available to order.

GENERAL AC Supply options: 240Vac   (default)   or   120Vac   (to   order),   +/-   10%,   <7VA, built-in thermal and over-current protection. DC Supply option: 12 to 24Vdc nominal (9 to 36Vdc guaranteed) <7W Dimensions: 146 x 195 x 44mm overall, W x D x H Weight: 1.3Kg (mains version), 1Kg (DC version) Other features:   The   front   and   rear   unbalanced   outputs   can   be   used simultaneously. The   front   and   rear   unbalanced   inputs   are   actively   mixed and do not interact. XLR    i/o    pin-3*    or    pin-2    'Hot'    (+ve    phase)    can    be selected internally by moving one connector. The     balanced     input     and     output     screens     can     be separately grounded* or left floating. 1U   front   panel   height   allows   convenient   mounting   on   a rack tray (up to 3 across) *Factory defaults: Pin-3 +ve and all screens grounded
The   Quest   AV   model   AB2C   is   a   high   performance   balancing,   unbalancing   and   level-shifting   stereo audio interface to use between domestic, semi-professional and professional equipment.
