There&are&two&reasons&why&we’ve&implemented&this&unique&functionality&in&the&Pro&iDSD:&
&
• All&digital&equi pment&in&many&recording&studios&is&oftentimes&synchronized&with&one&
standalone&master& cl ock&device.&We’re&confident& that&Pro&iDSD&can&be&used&in&such&an&
environment& but& in& order& to& do& so,& it& has& to& have& the& option& to& be& connected& to& a&
separate&master&clocking&deck.&&
• &
• Internal& space&limitation&of&Pro&iDSD& allowed& us& to& equip& it& with& the& best&clock&and&
tech&we&could&fit&inside,&but&there’s&room&to&maneuver&still.&If&one&has&a&really&good&
(we&mean&REALLY&good&–&Stanford& Research&Systems&PERF10&or&better)&external&clock,&
iFi&audio&has&provid ed&the&option&to&try&it&out&with&Pro&iDSD&and&go&with&what&sounds&
best.&
A& small& dial& found& in-between& the& BNC& connectors& allows& you& to& choose& one& of& four& clock&
synchronization&modes:&Atomic,%DARS,%IOMHz%and%standalone.&&

The&two&small&connections&just&above&the&external&cl ocki n g&dial&of&Pro&iDSD&will&be&familiar&to&
iESL&and& Pro&iDAC& owners.&The& one&on& the&left& is&a& DC-Loop&Out& and&its&purpose&is&to&feed&
