SFC Bench test device

Description

SFC is a sampling frequency converter; it converts the digital signal, inputting an S/PDIF digital signal with from 32

kHz to 192 kHz sampling frequency and outputting an S/PDIF digital signal with 48kHz sampling frequency.
SFC does not alter the information travelling along the signal, it can not handle AC3

®

or Dolby Surround

®

encoded

signals but just stereo PCM ones and does not convert the digital signal into analog.

SFC features two inputs: one coaxial electrical (75 Ω) and another optical (TOSLINK). You have to select which input

will be used through the INPUT MODE switch.
When the ERROR LED lights up, it indicates either that the input signal is not stereo PCM or that the signal is

instable; in that case, the SFC goes into “Mute” status not to damage the devices connected to its outputs.

SFC features two outputs: one coaxial electrical (75 Ω) and another optical (TOSLINK). Both the outputs are active

and if using the BIT ONE only one output has to be connected to it.

CONNECTION PATTERN:

1.

L’SFC offers two power supply connections; one can be connected to the 12V power supply while the other

can be used to supply the Bit One.

2.

Put a 1A fuse in the SFC main power cable.

Introduction

SFC is a digital audio signal adaptor (S\PDIF) to place between two devices with digital

input/output. The main purpose of this adaptor is to solve issues related to digital

interfacing of the two devices such as:

1.

Digital head unit with higher sampling frequency (96/192 kHz) while the receiver can’t

handle frequencies higher than 48 kHz like in the case of BIT ONE.

2.

The receiver/transmitter does not feature an optical or electric coaxial input/output:

the SFC can be used to recreate the missing connection.

3.

Malfunctioning or anomalous noises when the head unit is set to “Pause”. The issue

is caused by the fact that while being paused some head units strip away the digital

signal carrier wave; SFC constantly provides the carrier wave to the receiver.

4.

When “Play” is selected on the head unit and the music program is starter or

during normal functioning intermittent noises can be heard even at low volume. This

phenomenon is due to poor quality or insufficient level of the digital signal; SFC can

recover the signal eliminating the issue.
