CONNECTING TO A TURNTABLE

Balanced inputs are provided for con-

necting up to two turntables to the 1008.

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 tone-

arm. 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 ABL2 input

adapter or other “standard” RCA Phono

to XLR adapter because they connect pin

1 to pin 3. These are intended only for line level use.

Use either a connection from pin 1 to the turntable chassis or a wire

from the CHASSIS screw terminal to the turntable chassis. Using both

might form a ground loop which will create hum.

One pair of Boulder PHRCA Adapters are provided. These will

convert 1008 inputs to RCA and give acceptable performance. A sepa-

rate ground wire is provided. However, obtaining a dedicated cable

with a connector specifically for your tonearm and with 3-pin connec-

tors is preferred.
