The TD-4 percussion sound module supports rim 

shots only for the snare.  
It does not support rim shots for toms.

This explanation shows an illustration of the PDX-8.  

The PDX-8 and PDX-6 differ in diameter and in the number of tuning bolts, but their functionality is identical.

NOTE

Be sure to adjust the head tension of the 

PDX-8 before use.

Striking the head when the head tension 

is loose may damage the sensor and head.

Do not apply excessive force to the sensor 

and cushion located under the head. 
Doing so can interfere with accurate 
detection, and may damage it.

Due to the nature of the materials used in 

the sensor of the PDX-8, changes in room 
temperature may affect the sensitivity of 
the sensor.

The rim rubber is one component that 

eventually wears out (depending on the 
number and strength of the rim shots 
performed), and will require replacement.  
Rim shots may not be performed correctly 
when the rim rubber is worn out. If this 
occurs, replace the rim rubber. Consult 
Roland Service for more on replacing the 
rim rubber.

Remove all tuning bolts and washers.

1. 

Do not apply excessive force to the sensor and cushion located 

under the head. Doing so can interfere with accurate detection, 
and may damage it.

Remove the hoop.

2. 

Remove the old head.

3. 

Place the new head on the shell.

Placement

 

354a

 

• Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it 

inside an enclosed vehicle, or otherwise subject it to temperature extremes. Excessive 

heat can deform or discolor the unit.

 

356

 

• Do not allow rubber, vinyl, or similar materials to remain on the unit for long periods of 

time. Such objects can discolor or otherwise harmfully affect the finish.

 

add

 

• When setting up or storing this unit, be careful so the fingers used to grasp the stand 

don’t get pinched. Also, take care that the stand does not become unbalanced and fall 

over or fall against you.

 

Maintenance

 

401a

 

• For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly 

dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, 

non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry 

cloth.

 

402

 

• Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of 

discoloration and/or deformation.

 

Additional Precautions

 

553

 

• Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; 

and when using its jacks and connectors. Rough handling can lead to malfunctions.

 

556

 

• When connecting / disconnecting all cables, grasp the connector itself—never pull on the 

cable. This way you will avoid causing shorts, or damage to the cable’s internal elements.

 

558a

 

• To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels. You 

may prefer to use headphones, so you do not need to be concerned about those around 

you (especially when it is late at night).

 

558d

 

• This instrument is designed to minimize the extraneous sounds produced when it’s 

played. However, since sound vibrations can be transmitted through floors and walls to a 

greater degree than expected, take care not to allow these sounds to become a nuisance 

to neighbors, especially when performing at night and when using headphones.

 

562

 

• Some connection cables contain resistors. Do not use cables that incorporate resistors for 

connecting to this unit. The use of such cables can cause the sound level to be extremely 

low, or impossible to hear. For information on cable specifications, contact the manufac-

turer of the cable.

 

add

 

• The rubber portion of the striking surface is treated with a preservative to maintain its 

performance. With the passage of time, this preservative may appear on the surface as a 

white stain, or reveal how the pads were struck during product testing. This does not 

affect the performance or functionality of the product, and you may continue using it with 

confidence.

 

add

 

• Continuous playing may cause dis-coloration of the pad, but this will not affect the Pad’s 

function.

• In the interest of product improvement, the specifications and/or appearance of this unit 

are subject to change without prior notice.
