CONNECTING THE PADS(パッドの接続)
DTXTREME Ⅲ
Referring to the illustration below or next page, connect
the output cable from each pad to each Trigger Input jack
located on the rear panel of the DTXTREMEⅢ. All Trigger
Input jacks are conveniently labeled (qSNARE, etc.), so
make sure each pad is connected to its corresponding
Trigger Input jack.
WARNING
To prevent electric shock and damage to the devi-
•
ces, make sure the power is switched OFF on the
DTXTREMEⅢ and all related devices before making any
connections to the DTXTREMEⅢ’s input and output
jacks.

Notes on Flat Cable
Contacts are visible through the back side. When
connecting to the connector, pay attention not to
insert the cable inversely. (Photo A)
•
During assembly, pay attention that connectors,
cables or the like are not pinched by circuit boards,
frames, etc.

•Before beginning installation, switch off the power to the
instrument and connected peripherals, and unplug them
from the power outlet. Installation or removal of any devices should be started ONLY after the instrument (and the
optional hardware) returns to normal room temperature.
Then remove all cables connecting the instrument to other
devices. (Leaving the power cord connected while working
can result in electric shock. Leaving other cables connected
can interfere with work.)
•Be careful not to drop any screws inside the instrument
during installation. (This can be prevented by keeping the
optional units and cover away from the instrument while attaching). If this does happen, be sure to remove the screw(s)
from inside the unit before turning the power on. Loose
screws inside the instrument can cause improper operation
or serious damage.
•Install the optional units carefully as described in the pro-
cedure below. Improper installation can cause shorts which
may result in irreparable damage and pose a fi re hazard.
•Do not disassemble, modify, or apply excessive force to
board areas and connectors on optional units. Bending or
tampering with boards and connectors may lead to electric
shock, fi re, or equipment failures.
CAUTION
•It is recommended that you wear gloves to protect your
hands frommetallic projections on optional units and other
components. Touchingleads or connectors with bare hands
may cause fi nger cuts, and mayalso result in poor electrical
contact or electrostatic damage.
•Be careful of static electricity. Static electricity discharge can
damage the IC chips on the DIMM. Before you handle the
optional DIMM, to reduce the possibility of static electricity,
touch unpainted metal parts or a ground wire on the devices
that are grounded.
Handle the optical units with care. Dropping or subjecting
•
them to any kind of shock may cause damage or result in a
malfunction.
•Do not touch the exposed metal parts in the circuit board.
Touching these parts may result in a faulty contact.
•
Be careful not to misplace any of the screws.
Do not use any screws other than what are installed on the
•
instrument. Use of incorrect screws can cause damage.
The DTXTREME Ⅲ does not necessarily support all commer-
cially available DIMMs. Yamaha cannot guarantee operation of
DIMMs that you purchase.
Before purchasing DIMMs, please visit the following website:
http://www.yamaha.co.jp/english/product/drums/ed/
DIMM Typed and DIMM Confi guration
• Yamaha recommends that you purchase DIMMs that conform
to the JEDEC* standard. Please be aware, however, that conformance to this standard does not constitute a guarantee that
the DIMMs will operate correctly on the DTXTREME Ⅲ.
*
JEDEC (Joint Electron Device Engineering Council) sets
standards for terminal configurations within electronic
devices.
• Use only 168-pin DIMMs of 64, 128 or 256 MB capacity
(synchronized DRAM; PC100 or PC133).
• When installing DIMMs, make sure to install them in a
matched pair of the same capacity. You cannot install only
one module and leave the second memory socket open. Also
make sure each DIMM in the pair is of the same manufacturer and the same type. DIMMs of different makers and
confi gurations may not work together.
• When purchasing DIMMs, make sure that the DIMM design
does not utilize more than 18 memory chips per module.
(DIMMs comprised of more than 18 chips do not operate
correctly on the DTXTREME Ⅲ.)
