FLS DAC board
본 설명서는 FLS 시리즈 제품 (FLS1, FLS9, FLS10)에 장착 가능한
DAC모듈이 사용법을 설명합니다. 최상의 음질을 위해서 DAC 장착 후 최
초 100시간은 디지털 신호를 연결하고 앰프를 계속 작동하여 에이징하시
길 바랍니다.
FLS DAC board has been designed with intention of being the best D/A con-verter board
complement for FLS series (currently the preamplifier FLS 1, the integrated amplifiers FLS 9 and
FLS 10). The board has already been run for about 50 hours during which conformity and
operating tests have been also carried out. For best performance we advice you to go on
running for 100 hours more. Remember that it means in operating presence of signal.

Connection (연결)
보드를 장착하기 전에 모든 오디오 시스템의 전원이 차단 된 것을 확인 바
랍니다. DAC 보드를 장착하면 앰프에는 5개의 디지털 입력이 추가됩니
다. 이 5개의 디지털 입력은 전면의 Input 셀렉터와 볼륨 노브를 사용하거
나 리모컨의 + - 버튼으로 선택할 수 있으며 선택된 입력은 전면의 표시
창에 나타납니다.
Before connecting any audio cables, be sure that all components in your system are powered
off. When your FLS unit is equipped with this DAC board, five new digital inputs will be
added. These five inputs are available on the display by using input selector and volume
knob or with the IN and +/ –keys of remote control.
입력 번호와 입력단자의 타입은 다음과 같습니다.
Here is a table for these digital inputs:

SET menu configuration (환경 설정 메뉴)
DAC보드를 연결하면 환경설정 메뉴에 3개의 새로운 기능이 추가되어 보
여집니다. 이 세 기능은 5개의 디지털 입력에 관한 것입니다. 아래 표에서
청색으로 표시된 부분이 새로 추가된 DAC 환경설정 메뉴입니다.
Connecting the FLS DAC board, the software provides three new additional functions of SET
menu configuration. These functions only apply to the five digital inputs of FLS DAC board that
are also concerned by some of the pre-existing functions of the SET menu. Here is a table of all
the functions available by SET menu, blue highlighted entries are referred to DAC settings.

환경설정은 전면의 SET버튼이나 리모컨의 SET버튼으로 들어가고, 메뉴
간 이동은 볼륨노브 또는 + - 버튼으로 이동합니다. 이동하면 선택할 수
있는 기능이 깜박이며 그대로 두면 선택된 기능이 잠시 후 자동적으로 확
정되고 깜박임이 사라집니다. 잠시 후 상위 메뉴로 또는 초기 메뉴로 자
동적으로 화면이 바뀝니다. (다른 기기들과 달리, Audia 에는 선택을 확
정하는 OK버튼이 따로 없습니다).
Entering this mode is done by pressing SET button on front panel or the SET key of the remote
control. Navigation is done by rotating volume knob on front panel or +/ –keys of remote control.
SET key allows you to access each item. Rotating clockwise the volume knob or pressing +key
allows you to scroll down the different modes in the order of table above. Rotating counter-
clockwise volume knob or pressing the –key it will scroll up. The same actions are also used
to scroll through sub-modes. Choices are indicated by flashing characters on display and
scrolled by using volume knob or +/ –keys. Confirmation of selection is effective after a few sec-
onds without any action and after end of flashing. Heading (or sub-heading) is displayed again to
move to another one or after few seconds it returns to the initial screen. All settings are stored.
Here are the new functions of SET menu.

•mode SET PCM FILTER (6) PCM 필터 설정
이 (6 번) 메뉴는 디지털 입력에 적용되는
PCM필터를 선택할 수 있습니다. 총 7개의
필터가 있으며 각기 주파수를 감쇠시켜 소
리에 변화를 줍니다 . (아래 그림 참조)
이 메뉴를 선택하면 위 그림처럼 표시창 둘째 줄에 입력번호와 선택된 PCM필터
번호가 표시됩니다. 디지털 입력번호가 깜박이고 잠시 후 우측의 필터번호가
깜박입니다. 볼륨노브로 필터번호를 변경하고 가만 두면 잠시 후 변경된 내용
이 자동 저장됩니다.
By this function you can choose PCM filter is applied to each digital input. Each one of the 7 filters (from 0 to 6) have its roll-off frequency and slope
that affect slightly the sound. See table to illustrate differences among the 7 PCM filters. Upon entering this mode, display shows one of digital inputs
on second line. By acting SET, you confirm the selection of this input, otherwise you can choose another input with volume knob or + / –
keys and confirm choice with SET. The number of the PCM filter will then go on flashing on the right side of this second line. It will be validated
after few seconds without action and the character stops flashing. Otherwise, you can choose another number of PCM filter with the volume knob or
the +/ –keys. Validation is after few seconds and end of flashing. The same operation can be done with another input, otherwise display returns in initial
mode.

By this function you can choose the filter applied on DSD stream of USB input (DIGIT 5).Two
filters are avail-able in the analog domain after conversion: LOW (roll-off at 50 kHz and soft slope)
or HIGH (roll-off at 70 kHz and sharp slope).Upon entering this mode, display shows one of digital
inputs on second line. If input is not DIGIT 5 or USB, please get it by navigation with volume knob
or + / – keys. Then by acting SET, LOW or HIGH will go on flashing on the right side of second
line. You can choose one of two DSD filters that will be validated after few seconds at end of
flashing.
If another input is selected, LOW or HIGH will not go on flashing because this choice is not
available. Display returns to initial mode screen.

Dithering is a random digital noise that is added to incoming PCM sig-nal to make distortion, due to
quantization errors, less unpleasant after conversion. It can improve sound of the weakest signals
in particular. It can be applied on each one of the 5 inputs. This mode operates in the same way as
PCM FILTER mode. Display shows on second line one of the 5 inputs. A SET action will produce
the YES or NO flashing. Choice is validated after few seconds and end of flashing. Choice can be
done for another input or the screen returns in the initial mode.
These settings are referred to 1.38 software version of the unit that houses the card.
Previous releases support anyway all these functions but the entries not shown in this
manual are not active.

How to configure your Phono board 포노 보드 환경설정
보드에는 2세트의 딥스위치가 있씁니다. 좌측 것은 좌측 채널용, 우측 것
은 우측 채널용입니다. 위 그림은 모든 딥 스위치가 OFF 상태에 있습니다.
스위치 1~5번은 MC용이며, 6~8번은 MM용 스위치입니다.
Phono board has two, identical group of dip-switch (see above). The two dip-switch MUST be
configured always the same way, because one is for the left channel and the other one for the
right channel.
Picture shows the dip-switches position in “OFF”.
Group switches from 1 to 5 are dedicated for MC input load selection. Group switches from 6 to 8
are dedicated for MM input load selection.

MC input MC입력 설정
MC입력게인은 60dB입니다. 카트리지 임피던스에 맞추어 아래 표를 보시
고 딥 스위치를 조정하십시오. 만약 이 표에 없는 임피던스의 카트리지인
경우에는 모든 딥 스위치를 OFF로 놓고, 임피던스에 맞는 저항(1/4왓트)
을 구하여 아래 그림처럼 포노보드의 삽입홀에 장착하여 사용하십시오.
Connect to this input to MC cartridges only. The gain of MC input is 60 dB. To select the correct
input impedance (resistive), please refer to Table 1.
If it is necessary to use a different load value from Table 2, select the switches from 1 to 5 all in
OFF position and insert custom resistors in the two sockets as in following picture.
Please be sure that you use correct type resistors, i.e. 0.25 watt. In all cases, you MUST use exact
same resistor value for both right and left channel.

Connect to this input to MM cartridges only. The gain of MM input is 40 dB. To select the correct
input impedance (capacitive), please refer to Table 2. Most turntables have a separate ground
wire and this should be connected to the rear panel gold binding post (GND). If your turntable
does not have a separate ground wire, it may be advisable to run a separate wire from a metal
screw or grounded area of the turntable to this post. Turntables are very sensitive to hum and
grounding table, head shell or cartridge to Phono board can help lower hum.
