CONNECTING A DIGITAL SOURCEThere are four digital inputs to  the DSP and D/A Converter section 
of the 1012. Three inputs are the AES/EBU style. Because of the balanced 
nature of these connections, it is the preferred method of connection and 
should be used whenever available.
With the  1012, one  DABL  digital adapter  is  supplied and  may  be 
plugged into any  one of these  inputs thus converting  it to RCA  phono 
style SPDIF. Additional  adapters are  available  if more  than one  input 
needs conversion.
WARNING:  In  order  to  maintain  proper  impedance  and  level 
matching, it is important to always use the DABL adapter when coming 
from  an  unbalanced  RCA  phono  style  digital  source.  Do  not  use  a 
Boulder ABL analog adapter for this purpose.
The fourth connector normally supplied is toslink optical.
For possible future connections, consult your Boulder dealer.
