-Phase Control Switch - This toggle switch allows the user
to invert the system phasing easily and safely. When the switch
is in the 0° position the SFD-1 MKII will put out a normal or
non-inverted signal in relation to the signal being received from
the source. When the switch is in the 180° position the SFD-1
MKII will put out an inverted version of the signal as compared
to that being received from the source. This feature offers a
convenient method of correcting source material which was
recorded “out of absolute phase” or to counteract for a compo-
nent in your system such as a preamplifier, power amplifier or
signal connection which inverts phase.

-HDCD®- This LED will light when an HDCD (High Definition
Compatible Digital) encoded digital track is being played. The
HDCD decoding is switched in automatically by the SFD-1
MKII circuitry, and no user adjustments are necessary.
B - Signal Locking Indicator LED - This LED will light when
an operational digital source is selected.
NOTE: Depending on the source or transport being used in
conjunction with the SFD-1 MKII, it may be necessary to have
the source unit in the “play” mode and the SFD-1 MKII receiv-
ing the digital transmission before the LED will light.
C - Input Selector Switch - This 3 position toggle switch
selects between the three digital inputs located on the back of
the SFD-1 MKII: Toslink (Plastic Fibre) Optical, RCA Coaxial
Cable and ST (Glass Fibre) Optical. A connection to all 3
inputs may be made from 3 separate sources. The Signal
Locking Indicator LED (B) will light when the source is activated
in conjunction with the input chosen by this switch.
D -Power Indicator LED - This LED will light when the Power
Switch (E) is in the ON position and the SFD-1 MKII is receiv-
ing power.
E - Power Switch - This toggle switch, when switched to the
ON position, allows the SFD-1 to receive power, rendering the
SFD-1 MKII operational as indicated by the Power Indicator
LED (D). When the switch is in the OFF position the SFD-1 MKII
is not receiving power and is not operational.

THE HDCD PROCESS
The SFD-1 MKII includes a free HDCD-encoded sampler CD to
demonstrate the HDCD process. This process is a true advance-
ment in digital audio reproduction, providing one of the single
greatest improvements in digital audio since the introduction of
the CD format more than a decade ago. This sophisticated
encoding/decoding system greatly reduces both additive and
subtractive distortions in digital recordings, providing a resolu-
tion and freedom from distortion equal to that of analog record-
ings. In addition, the HDCD decoder’s internal digital filter pro-
vides significant sonic improvements to non-HDCD source mate-
rial as well.
