H -Detachable Power Cord Socket - Plug the Detachable
Power Cord into this socket (see Figure 1). The SFD-2 is factory
set for the correct operating voltage for the area in which it is
sold (see shipping box for voltage setting). If a different operat-
ing voltage is required, please contact an authorized Sonic
Frontiers dealer, distributor or the factory directly.
I - Digital Out - This output jack provides a digital signal for
dubbing purposes with a Digital Audio Tape (DAT) or
Compact Disc recorder (CD-R). The signal source is selected
through the front panel Input Selector Switch (E).
J - AT&T/ST (Glass Fibre) Optical Input - This input will
accept a digital connection from a digital source's Glass Fibre
Optical digital output (see Figure 3). This connection type is con-
sidered best for optimum performance and sound quality; if your
source unit has this type of digital output we recommend it's use.
K -RCA Coaxial Cable Input - This input will accept a digital
connection from a digital source's RCA - S/PDIF - Coaxial digi-
tal output (see Figure 3). The RCA - S/PDIF - Coaxial cable
impedance should be 75 ohms.
L - AES/EBU XLR Input - This input will accept a digital signal
from a digital source's AES/EBU XLR digital output (see Figure
3). A 110 ohm balanced cable terminated with XLR plugs
should be used for this connection.
NOTE: The XLR jack pin connectors for the SFD-2 are config-
ured as follows: Pin #1 : Ground
Pin #2 : Positive (+) Phase
Pin #3 : Negative (–) Phase

M-Left and Right Channel Balanced XLR Audio
Output Connectors - These are balanced audio outputs
and should be used when connecting the SFD-2 to the
balanced audio inputs of a line level preamplifier, control
amplifier, integrated amplifier or receiver, if these units are so
equipped (see Figure 4). (Left channel output of the SFD-2 con-
nects to the left channel input of control unit and right channel
output of the SFD-2 to the right channel input of control unit.)
NOTE: The XLR jack pin connectors for the SFD-2 are config-
ured as follows: Pin #1 : Ground
N-Left and Right Channel RCA Single-Ended Audio
Output Connectors - If the balanced inputs are not applica-
ble for use, the RCA single-ended (unbalanced) audio outputs
should be used when connecting the SFD-2 to the RCA single-
ended audio inputs of a line level preamplifier, control amplifier,
integrated amplifier or receiver. (Left channel output of the SFD-2
connects to the left channel input of control unit and right chan-
nel output of the SFD-2 to the right channel input of control unit.)
Figure 1 - Align socket pins to corresponding holes and push together firmly.
