FEATURES
High-End Preamplifier
The DAC 1000 is specially designed to guarantee the full fidelity of high-end sound reproduction
for almost a lifetime usage. High quality Digital volume control and dual monaural design provide
excellent separation with pinpoint imaging. Should you want to use DAC 1000 as a pure D to A
Converter with a fixed output, a switch on the rear panel makes this change possible by selecting
“FIXED” mode instead of normal “VARIABLE” mode.
•Analog Input:
1 XLR Balanced Input
1 RCA Unbalanced Input
•Analog Output (Main Out):
1 XLR Balanced Output
1 RCA Unbalanced Output
•Full Class A Output Stage
•High Quality Digital Volume Control
•Separate Transformers for the Digital and Analog stages
Selectable, Upsampling Digital to Analog Converter
Oracle DAC 1000 is a dedicated stand-alone D/A Converter. The DAC section has an upsampling
function up to 192kHz (24Bit) which is selectable by the user.
•Digital Input:
2AES/EBU (Balanced)
2 Coaxial (RCA)
2 Optical (Toslink)
•24 Bit /192 kHz, Delta-Sigma DAC
•Custom designed digital filter :
Specially designed digital filtering circuitry is used in DAC 1000 to enhance the
quality of sound by providing a cleaner signal with an excellent signal to noise
ratio.
•PLL Circuit :
For a jitter-free signal, special PLL circuit is applied in the Digital section.

Upsampled (24Bit/96kHz) Digital Recording Output
The DAC 1000 is equipped with 4 digital outputs for direct digital recording. You can easily make
high quality recordings of your favourite digital sources by connecting the cable between DAC
1000 and your digital recorder.
•Digital Output :
1 Balanced AES/EBU
2 Coaxial
1 Optical Toslink
Surround (Input for surround processor)
DAC 1000 provides a ‘Surround’ input for a simple connection to your surround processor.

CONNECTION PROCEDURE
On the rear of DAC 1000, there are:
•2 Analog Outputs (1 Balanced, 1 Unbalanced)
•2 Analog Inputs (1 Balanced, 1 Unbalanced)
•6 Digital Inputs and 4 Digital Outputs and the analog ‘Surround’ input
•Also included is a 12V trigger output.
•
Note: Be sure to turn the power off when you change mode switches " Output " and "
record".

Analog Input
yBalanced :
XLR Balanced input is used for the finest quality sound. Connect your equipment
which has an XLR/Balanced Output by a Balanced Interconnect.
yUnbalanced :
RCA Unbalanced input can be plugged into this input. Output from FM Tuner,
Tape-Out, VCR-Out etc. can be connected into this input.
ySurround :
For home theater use only. Connect main out from your surround processor with
this ‘Surround’ input. When in Surround mode, the volume control of the DAC
1000 is not valid. You should control the volume from the surround processor.
The display window on the front panel shows “SURROUND MODE”.
Another press of ‘Surround’ button will bring you back to normal DAC 1000
status.
Analog Output
XLR Balanced & RCA Unbalanced outputs are provided for the connection of power amplifiers.
Both outputs can be used at the same time.
Note: We recommend XLR Balanced connection for better performance.
yFixed/Variable switch :
The DAC 1000 is designed primarily to be used as a DAC/Preamp in which case
the switch should be in ‘VARIABLE’ mode (default mode).
But, for those who already own a high-end preamplifier, the DAC 1000 can
be switched to a fixed-output Digital to Analog Converter. To use the DAC
1000 as a pure DAC Stage, change output mode switch on the rear panel to
‘FIXED’ mode.
Warning! Be sure to turn the power “OFF” when you change mode switch.
Digital Input
AES/EBU Balanced Digital is the best solution for Digital playback when connected to the
transport with 110 ohm balanced digital cables. Coax 1 & 2 are generally used ports for digital
connection. Optical Toslink is for optical connection. Use proper Toslink optical cable for this
connection.
Digital Output
The DAC 1000 routes digital input signals to its 4 digital outputs. You can designate the specific
input to be routed on 4 digital output ports by pressing ‘RECORD’ button either from the remote
or from the front panel.

SAFE OPERATING INSTRUCTIONS
Front Panel Buttons
Front Display
Function Key
Standby The main power switch is located on the back side. Once the
main power switch is on, the display shows “ORACLE AUDIO
DAC 1000” and changes to a normal display mode as follows:
yWhen FIXED/VARIABLE switch is in “VARIABLE” :
REC_OFF 192 kHz
D1_AES1 0.0
yWhen FIXED/VARIABLE switch is in “FIXED” :
REC_OFF 192 kHz
D1_AES1 FIXED
When you push the ‘Standby’ switch to turn DAC 1000 off ,the
display shows “Standby”. A very small current is used when in
“Standby” mode. We recommend leaving the main power switch
‘on’ under normal circumstances.
When you are away from home and the DAC 1000 is not in use
for a long time, turn the main power ‘off’. In normal use, use the
“Standby” switch to activate and deactivate the system. If you

DAC 1000 D/A converter + pre amplifier
11
have a 12V trigger cable connected to your power amplifier, a
push of ‘Standby’ button will automatically turn on the power
amplifier.
In “Standby” mode, the DAC 1000 memorizes the volume level of
all inputs. A sudden ‘Click’ sound can surprise you, so proper
setting of the volume level control before going to ‘standby’ is
always recommended.
Input The DAC 1000 has a total of 8 inputs (6 digital inputs and 2
analog inputs). The first default input is ‘D1_AES1’ and the
volume level is displayed on the lower right side of the display.
Output level starts from 00.0 to 59.5 with a 0.5 step to show a
total of 120 steps. Pressing ‘Input’ continuously shows the
selection as follows.
yFixed mode :
D1_AES EBU1 ÆD2_AES EBU2 ÆD3_COAX1 ÆD4_COAX2 Æ
D5_TOS1 ÆD6_TOS2 ÆD1_AES EBU1…
yVariable mode :
D1_AES EBU1 ÆD2_AES EBU2 ÆD3_COAX1 ÆD4_COAX2 Æ
D5_TOS1 ÆD6_TOS2 ÆA1_BAL ÆA2_UNBAL
Surround To use this function, the DAC 1000 should be in "variable
mode". For home theater use only.
Upsampling Upsampling of the digital signal makes a very delicate sound
change.DAC 1000 enables the user to choose one from 4
different sampling rates. They are Bypass, 48kHz, 96kHz, and
192kHz.Bypass means sampling rate is just passed through as it
is. Therefore, no change of sampling rate is done when ‘Bypass’
mode is selected. You should be the judge for the changes of
the sound. Pressing ‘UPSAMPLE’ and experiment by
yourself.
Record Choose the input you want to record and upsampling (96kHz)
Bypass/ Upsample selection on the rear panel. The status for
record is displayed on the upper left side of the display.
yBypass mode :
REC_OFF ÆD1_AES EBU1 ÆD2_AES EBU2 ÆD3_COAX1 Æ
D4_COAX2 ÆD5_TOS1 ÆD6_TOS2 ÆREC_OFF…
yUpsample mode :
REC_OFF ÆD1_AES EBU1 ÆD2_AES EBU2 ÆD3_COAX1 Æ
D4_COAX2 ÆD5_TOS1 ÆD6_TOS2 ÆREC_OFF…
The upper middle selection on the display identifies 96kHz digital

output. Be sure to turn the power off when you change BYPASS /
UPSAMPLE mode switch.
Vol Up / Vol Down To control the volume, use the up and down buttons. Volume
varies from 00.0 up to 59.5, and MAX (120 Step). When in
“Standby” mode, all the volume level are memorized. And they
are recovered when the unit is on again. The main power-off from
the rear panel will erase the level information from DAC 1000
REMOTE CONTROL OPERATION
The remote control handset
The remote control handset of your Oracle Dac 1000 can control the Oracle CD 1000 or other cd
player model, by using the code RC-5.
Battery installation procedure
Remove the back cover on the remote control handset. Install two "AAA" batteries following the
proper polarity. Test the remote control handset for proper operation. Install back cover.
Note: It is strongly recommended to use Alkaline batteries for an extended cycle
operation of the remote control handset but more importantly to prevent any
chemical leakage.
