OWNER’S MANUAL UPDATE T H E S ONI C F RO NT IE R S SF D -1 M KI I DI G IT AL PRO C ESS OR A1 A2 B C D E A1-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 component in your system such as a preamplifier, power amplifier or signal connection which inverts phase. 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. A2-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. 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. 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 receiving the digital transmission before the LED will light. D-Power Indicator LED - This LED will light when the Power Switch (E) is in the ON position and the SFD-1 MKII is receiving power.

This process is a true advancement 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 resolution and freedom from distortion equal to that of analog recordings. In addition, the HDCD decoder’s internal digital filter provides significant sonic improvements to non-HDCD source material as well. 5.0 Volts (HDCD/S.E.) 10.0 Volts (HDCD/balanced) 2.5 Volts (non-HDCD/S.E.) 5.0 Volts (non-HDCD/balanced) 2790 Brighton Road, Oakville, Ontario, Canada L6H 5T4 Telephone: (905) 829-3838 Facsimile: (905) 829-3033 Sonic Frontiers can be reached from 9:00 a.m. to 6:00 p.m., Eastern Standard Time (E.S.T.), or 24 hours a day by facsimile.
