[Important Check Points for Good Servicing]

In this manual, procedures that must be performed during repairs are marked with the below symbol.
Please be sure to confirm and follow these procedures.

1. Product safety

Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by
following the safety instructions described in this manual.

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.

Caution)
When you disassemble/re-assemble the Product
with it placed upside down, take care not to
damage the top surface.

The Product uses several different types of
screws. Take care not to confuse them during
re-assembly.

Panels are used for two sides individually, one
for the RCA side and the other for the Power
Terminal side.

Removing the Amp Unit (Fig. 3)

Screw holes in the PCB are printed with
numbers 1 to 12.

Remove screws in numerical order.
Re-assembly takes the reverse order of
disassembly.

Remove all of the twelve screws. Then,
remove the two black screws (M3 x 5).
Tighten screws whose length is M3 x 8 or
more into the two screw holes so as to
raise the Amp Unit above the Heat Sink.
Then, remove the Amp Unit.

Caution)
The Amp Unit is adhered on the Heat Sink with
silicon grease. This means forcibly removing the
Amp Unit from the Heat Sink may break the
PCB.

Be aware that the RCA Terminal may break
unless the Amp Unit and the Heat Sink are
assem-bled following the correct procedures
given below.

1) Secure the RCA-side Panel on the Heat Sink
with screws. (Fig. 2)

2) Place the Amp Unit on the Heat Sink aligning
with two studs. (Fig. 4)

3) Move the Amp Unit until the RCA Holder on
the Amp Unit comes in contact with the inside
of the Panel. (Fig. 4)

Caution in steps 2) and 3)
When you place the Amp Unit on the Heat Sink,
you will find no positioning marks to determine
the direction of two panels. To position them
correctly, the Amp Unit needs to be moved to
the place where it comes in contact with the
RCA-side panel.
If you do not position them, an excessive force
can be applied to the RCA Terminal. This may
result in breakage.

4) Secure the RCA-side Panel and the RCA
Holder with screws. (Fig. 2)

5) Secure the Amp Unit on the Heat Sink with
screws. (Fig. 3)

6) Secure the Panel for the Power Terminal side
in place with screws. (Fig. 2)

8. OPERATIONS (GM-5100T/XU/EW)

LPF (Low-Pass Filter) Select Switch

Set the LPF select switch as follows according to the type of speaker that is connected to the

speaker output connector and the car stereo system:

LPF Select Audio frequency range Speaker Remarks

Switch to be output Type

LPF (right) Very Low Frequency range Subwoofer Connect a subwoofer.

OFF (left) Full range Full range

BFC (Beat Frequency Control) Switch

If you hear a beat while listening to an MW/LW

broadcast with your car stereo, change the BFC

switch using a small standard tip screwdriver.

Power Indicator

The power indicator lights when the

power is switched on.

Gain Control

If the sound level is too low, even when

the volume of the car stereo used along

with this power amplifier is turned up,

turn gain control on the front of the

power amplifier clockwise. If the sound

distorts when the volume is turned up,

turn the gain control counter-clockwise.

• When using with an RCA equipped car

stereo (standard output of 500 mV), set to

the NORMAL position. When using with

an RCA equipped Pioneer car stereo with

max. output of 4 V or more, adjust level to

match the car stereo output level.

• If you hear too much noise when using the

speaker input terminals, turn the gain

control counter-clockwise.

Bass Boost Level Control Switch

Bass boost level control can boost the

level around the frequency selected by

the bass boost frequency control switch

from 0, 6, and 12 dB.
