CONNECTING A TURNTABLEBalanced inputs are provided for connecting a turntable to  the 1012. 
To avoid  hum  pickup  in  the cabling,  it  is  important  to  follow  these 
instructions.
Do not  connect pin  1  (chassis/ground) to  either pin  2 or  3  at any 
point in the cable, turntable chassis, or tonearm.  Pins 2 and 3 must only 
connect  directly  to  the  cartridge  pins.  This  can  be  accomplished  by 
several wiring schemes shown on the next page.
Do not use  the Boulder ABL  input adapter  or other RCA  Phono to 
XLR adapter.
Use either a  connection from  pin 1 to  the turntable  chassis or  wire 
from the CHASSIS  screw terminal  to the  turntable chassis,  but do  not 
use both.
For high level, moving magnet (MM) type cartridges, set the LEVEL 
switch to HIGH. For low level, moving coil (MC) type cartridges, set the 
LEVEL switch to LOW.
If in doubt, consult your Boulder dealer.
