A -Power Input Socket- Plug the Preamplifier Power Cord (M) from
the Power Supply into this socket. Simply align the plug and socket so
the plug inserts easily and freely when pushing the connection together.
Screw on locking ring allowing it to click to secure the connection
(see Figure 1).
B -Sets 1 & 2 of the XLR Balanced Outputs- These outputs are
balanced and should be used when connecting outputs to another
balanced unit. These two outputs allow for easier biamping and
greater flexibility when dealing with components such as electronic
c r o s s o v e r s ,etc. As with all outputs and inputs on this Preamplifier the
left channel is situated on the upper row of connectors and the right
channel is on the lower row.
C -Sets 1 & 2 of the RCA Single-Ended Outputs- These unbal-
anced outputs are single ended and should be used when connecting
the outputs to another single-ended unit. These two outputs, as with the
XLR outputs (B), allow for easier biamping and greater system flexibility.
D -RCA Single-Ended Tape Output - These outputs connect to the
inputs of a tape deck. When not recording these outputs should be
muted via the Record/Off Switch (O).
E -RCA Single-Ended Auxiliary Input - This input will accept a
single-ended input connection from a high-level source such as a
V C Ror a step-up device for a moving coil or moving magnet phono
cartridge such as our SFP-1or SFP-1 Signature Phono Stage.
F -RCA Single-Ended Tape Input - This input accepts a single-
ended input connection from a tape source.
G -RCA Single-Ended Tuner Input - This input accepts a single-
ended input connection from a tuner source.H -RCA Single-Ended Compact Disc Input - This input accepts a
single-ended input connection from a compact disc player or a digital
-to-analog processor such as our SFD-1 or SFD-2.
I -Direct RCA Single-Ended Input - This input accepts a single-
ended input connection from any source to achieve the highest possi-
ble sonic performance, bypassing the Balance Control (Q) and the
Record/Off Switch (O).
J -Direct XLR Balanced Input - This input accepts a balanced
input connection from any source to achieve the highest possible sonic
performance, bypassing the Balance Control (Q) and the Record/Off
Switch (O).
K -Detachable Power Cord Socket - Plug the Power Supplys
Detachable Power Cord into this socket (see Figure 2). The SFL-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 operating volt-
age is required, please contact an authorized Sonic Frontiers dealer,
distributor or the factory directly.
L -AC Line Fuses - These are the left and right channel AC fuses. They
may be accessed with a small slot screwdriver by turning a 1/2 turn
counterclockwise to unlock a spring that ejects the fuse holders out.
The unit is factory installed with fast-blo 1.5 Amp 250V (0.25 x
1.25) or 0.75 Amp 250V (0.25 x 1.25) for European
and Asian versions.
M-Power Supply Umbilical Cord - This Umbilical Cord exits the
Power Supply to plug into the Power Input Socket (A) on the SFL-2
Preamplifier (see Figure 1 for connection). It does not disconnect from
the Power Supply.ABCDEFGHIJKLM
