SAFETY INFORMATION
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE APPLIANCE TO THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are
often not evident from visual inspection nor the protection
afforded by them necessarily can be obtained by using
replacement components rated for voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this Service Manual.
Electrical components having such features are
identified by marking with a > on the schematics and on
the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER Service
Manual. A subscription to, or additional copies of,
PIONEER Service Manual may be obtained at a nominal
charge from PIONEER.

1 Use specified parts for repair.
Use genuine parts. Be sure to use important parts for safety.
2 Do not perform modifications without proper instructions.
Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as
radio/TV interference and foreign noise.
3 Make sure the soldering of repaired locations is properly performed.
When you solder while repairing, please be sure that there are no cold solder and other debris.
Soldering should be finished with the proper quantity. (Refer to the example)
4 Make sure the screws are tightly fastened.
Please be sure that all screws are fastened, and that there are no loose screws.
5 Make sure each connectors are correctly inserted.
Please be sure that all connectors are inserted, and that there are no imperfect insertion.
6 Make sure the wiring cables are set to their original state.
Please replace the wiring and cables to the original state after repairs.
In addition, be sure that there are no pinched wires, etc.
7 Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
0 Safe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

S-EW2
~ With playback of Dolby* Digital, establishment of a
special channel for the subwoofer is recommended; and
with playback of LFE (Low Frequency Effect: sound
effect like the rumbling of the earth, whose purpose is
to intensify the force of the video), the S-EW2 is
especially effective.
Dolby* Digital
Dolby Digital is the name of the Dolby Surround multi-
channel digital system that was developed from Dolby
Surround, as a continuation of Dolby Pro Logic Surround.
Dolby Digital is also referred to as a 5.1 channel system.
This is because it has 5 channels in the 20 Hz to 20 kHz
frequency range (front left and right, center , and rear left
and right) and an independent channel for the subwoofer.
The subwoofer channel is also referred to as LFE (Low
Frequency Effect).
The LFE channel is used according to individual tastes to
enhance the bass effect.
7 85 W power that serves video software playback such as
Dolby* Digital with a wide dynamic range.
7 Equipped with 16 cm driver
7 Turnover frequency can be continuous (50 Hz to 200 Hz).
7 Phase conversion switch (0°/180°).

IN COMBINATION WITH SPEAKERS
The frequency characteristics of the S-EW2 combined with
small-size speakers are shown below. As shown in these
figures, the low frequency range is improved.
~ These special characteristics are obtained in an echoless
chamber. The effect of an additional S-EW2 in an
ordinary listening room is better than the chart indicates
when positioned adequately.
