Owner's Information
Carefully unpacking your Pre-2DSP and locate the enclosed accessories:
Please read the operating instructions before connecting the Pre-2dsp to your audio/video system.
Thank you for your purchase of the Audio Refinement Pre-2dsp, pre/processor. It is precisely crafted
innovatively designed and extremely reliable. We appreciate your faith in our products and we trust
that your Pre-2dsp will reward you with many years of audio/video pleasure.
Audio Refinement was conceived to offer the renowned musicality or "sonic signature" of YBA
Electronics by Yves-Bernard ANDRE' in a more affordable range of products. It benefits from the
same design philosophy and attention to minute detail that is the hallmark of YBA.
The choice of materials is also an important part of the design of your Audio Refinement Pre-2dsp,
the bottom is made of non-magnetic aluminum, the other parts are brushed and colored
aluminum.
The transformer is suspended to reduce the transmission of its vibrations to the rest of the circuitry.
The PRE/PROCESSOR has only 3 feet which is the ideal way to drain vibrations.
The mechanism is designed to be as compact and as rigid as possible. The small physical size of
your Audio Refinement Pre-2dsp moves the resonant frequencies out of the audio domain.
An important design goal for Audio Refinement is the control of parasitic vibrations. These me-
chanical vibrations in the air have a negative effect on the purity of sound. The impact of these
vibrations depends on the size of the audio equipment, the internal components and the rigidity
of the construction. The solutions chosen for Audio Refinement include:
DESIGN PHILOSOPHYDESIGN PHILOSOPHY
Do not handle your AC cord with wet hands. If liquid spills on your Pre-2dsp, unplug immediately
and contact your dealer for cleaning instructions.
To avoid damage to your Pre-2dsp, we recommend that you disconnect the AC during electri-
cal storm or if the unit will be unused for an extended period of time.
Ensure that your main AC voltage matches the voltage marked on the rear of the unit and on the
exterior of the shipping carton.
CARE & USECARE & USE
Do not remove the top cover of your Pre-2dsp or attempt to modify any circuitry. This will void your
guarantee and could result in serious injury.
Always turn the Pre-2dsp off before making any connections. Ensure that the speaker cables of
your power amplifier do not touch each other. A short circuit will damage the unit and is not
covered under the guarantee!
Keep your Pre-2dsp out direct sunlight. Because it could interfere with the remote control sensor.
Keep the Pre-2dsp away from heat sourcres such as hot air ducts, radiators and moistures sources
such as open windows.

PRE-2DSP REMOTE CONTROL

In the following pages, detailed explanations are given to guide you thru the proper operation of Pre-
2dsp. As you might have noticed, there is 8pcs of buttons on the front panel. The Pre-2dsp was
purposely designed this way to eliminate the hassle of having too many buttons/knobs. Our engineers
have designed a user-friendly remote control unit that the entire operation of Pre-2dsp will be solely
based on. With the Pre-2dsp remote control unit, you are able to execute all the system configurations
and settings.
Operation - LCD and LEDsOperation - LCD and LEDs
1. Press the power button to turn the Pre-2dsp on, press it again to turn it off.
2. When power is pressed off with AC Line be plugged, Pre-2dsp will do the followings:
a. Both LCD display and Speaker Configuration LEDs are off.
b. Power indicator LED remains on.
c. Decoder status and user configurations are memorized.
d. Once the power is turned on again, Pre-2dsp will resume to its previous decoder status and
user configurations.
3. When Power Button is pressed off with Main AC line unplugged, Pre-2dsp will do the followings:
a. LCD display, Power indicator LED and Speaker Configuration LEDs are off.
b. Decoder status and user configurations won't be memorized.
c. Pre-2dsp will reset to factory default if the AC Line is plugged back to AC outlet.
Digital Inputs D3 and D4 have better sound results. For important digital recording, the source of
sound is recommended to enter through these two sockets.
The ANALOG Audio Input A2 has shorter and better signal path. Important analog signals should go
through this socket.
After completion of parameter setting for Pre-2dsp, please store the information into Preset 1
Preset 5 before turning power off. Then, after about 10 seconds, turn on the equipment again. In
this way, the whole setting parameters will maintain the state before the equipment is turned off.
Through this ON/OFF action of power button, the sound will have better quality.
When performing adjustment of channel volume balancing, we recommend adjusting the L, R, and
C to 5dB position before balancing other sound channels. This will result in faster adjustment results.
Using two-channel stereo mode, we recommend adjusting the L/R channel balance volume LEVEL
to 0dB (maximum value) and use MASTER button to control volume. This will result in better sound
quality.
Store the parameter settings that most often use in the Preset 1 position. This is because when the
first time the power in turned on and activated the main switch of the equipment will resume the
settings in Preset 1 as the initial values.
During manual testing mode of TEST/M, MANAGER must be set to CONFIG 1. At this time, LFE sound
channel will start to send signal. During setting of other CONFIG2, 3, and CONFIG OFF, LFE will not
send out test signal.

Video entering V1, V2, V3, and V4 can only output from (V OSD) MONITOR.
S connector video entering S1, S2, S3, and S4 can only output from (S OSD MONITOR).
The OSD display signal output from S connector is taken from VIDEO connector as background
signal. Therefore, if activation of OSD signal is required together with TV screen display the same,
it is necessary to input the same video signals entering S connector into the corresponding VIDEO
connector. Only in this way could both video and OSD signals be displayed at the same time.
For example, if there is no signal in VIDEO connector, TV screen will generate blue background
automatically. The reason for choosing this method is in order that S connector can maintain the
best video quality when OSD is not activated. When OSD is OFF, the output from S connector is
completely independent and not mixed with OSD signal at any time.
If component connector is used, OSD display function and the recording function will not function.
Though A1 A4 and D1 D4 have corresponding VIDEO input and seem redundant, when in use
it is possible to accompany the TV to switch between different video input and used alternatively.
For example: A1 audio input and corresponding video is DVD component connector. But when
choosing D1, it is also possible to plug in V1 or S1, and make use of TV video input to select
component connector as input, or S1 and V1 as input signals. In this way, it is possible to extend
more video inputs.

In order that your home theater could have the most idealistic audio effect, you can place speakers
by following the directions as shown below:
Placement of front speaker:
Like the commonly used stereo sound speakers, the front speakers should be placed on the front right
and front left positions at the same distance to the TV at the center.
Placement of center speaker:
The center speaker should be placed in the middle of the two front speakers, such as below the TV or
on top. When you are sitting in sofa and the center speaker is at the same height as your ears, this is
the best height for you.
Placement of surround speakers:
The two surround speakers should be facing each other and on the same line with the listeners, or
placed slightly behind the listener. If possible, install the surround speakers at positions slightly higher
than human ears for best result.
Placement of subwoofer:
As sub woofer does not have direction, it can be placed anywhere at front. Closer to the corners of
the walls will have good bass effect.
Notice: If front and center speakers are too close to TV, please use anti-magnetizer in order to prevent
the magnetic field from interfering with the TV screen.
In order to reproduce the complete and real DTS digital sound effect, the center channel and the
back channels as well as the front channels are all full bandwidth speakers.

DELAY CALIBRATION
SPEAKER PLACEMENT

In this reason, the sound imaging not as sharp and stable as it could be. For audible improvement,
the sound from center speaker could be delayed with the center delay time setting to synchronize
the sound from the front and the center speaker and the sound from the rear speaker could be also
delayed with the rear delay time setting so that the sound from the front and the rear speakers will be
heard at the same time.
The optimum delay time depends on the speaker placement in your room.
It is adjustable in DTS Dolby digital and Dolby Pro Logic modes only.

In the Dolby Digital mode, the optimum performance of your system occurs when the sound from all
five speakers arrives at your primary listening position at the same time.
If all speakers are equidistant from the main listening position, set the following delay.
Center delay time: 0 mS, Rear delay time: 0 mS
If the center speaker is closer to your prime listening position than the average distance to the left
and right main speakers add 1 mS of center channel delay for each foot of difference. The maximum
is 5 mS.
If the surround speakers are closer to your main listening position than the main left and right speakers
add 5 mS of surround channel delay for each 5 feet of difference. The maximum is 15 mS.
Note: The propagation speed of sound is 34 cm /mili-second (/ms).

Delay calibration for the surround speaker is necessary when the surround speakers are placed
quite closed to the listener. The type of placement would probably ruin the sound quality of
Your movie. To correct this problem, press Delay Button repeatedly until SL/SR appear on the
