CONNECTING A TURNTABLE
Balanced 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.
