Yamaha DTXPRESS Owner's Manual

Introduction

Thank you for purchasing the YAMAHA DTXPRESS. This manual provides comprehensive instructions for operating your DTXPRESS, a compact drum trigger module equipped with an AWM tone generator and sequencer functions. Please read this manual carefully and keep it in a safe place for future reference.

The manual is divided into two main sections: Basic Guide (covering setup, controls, and fundamental operations) and Reference (detailing each function in depth). An Appendix includes specifications, error messages, and lists of voices, songs, and setups.

About the descriptions: Button names are indicated with square brackets (e.g., [PLAY]). Combined button presses are shown as [SHIFT]+[START/S]. Page references are indicated by m P. X. Display messages are shown in quotes (e.g., "Complete!"). Illustrations are for instructional purposes and may differ slightly from the actual unit.

Inside this package: The DTXPRESS unit, Power Adaptor, and this Owner's Manual.

Precautions

WARNING: To avoid serious injury or death from electrical shock, short-circuiting, damages, fire, or other hazards:

• Do not open or modify the instrument. It contains no user-serviceable parts. Contact qualified Yamaha service personnel for any malfunctions.
• Do not expose to rain, use near water, in damp conditions, or place liquid containers on it.
• Immediately turn off power and disconnect the AC adaptor if the cord/plug is frayed or damaged, if sound is lost, or if unusual smells/smoke appear. Have the instrument inspected by qualified service personnel.
• Use only the specified AC adaptor (PA-3B or equivalent).
• Always unplug the instrument before cleaning. Never insert/remove plugs with wet hands.
• Periodically check the electric plug for dirt or dust.

CAUTION: To avoid physical injury or damage to the instrument/property:

• Keep AC adaptor cords away from heat sources, do not bend or damage them, do not place heavy objects on them, and prevent tripping hazards.
• Always hold the plug, not the cord, when removing it.
• Do not connect to an electrical outlet using a multiple-connector.
• Unplug the AC adaptor when not in use or during electrical storms.
• Turn off power for all connected components before connecting/disconnecting or powering on/off. Set all volume levels to minimum before powering on and gradually increase while playing.
• Avoid excessive dust, vibrations, extreme temperatures, or direct sunlight to prevent damage.
• Do not use near other electrical products (TVs, radios, speakers) to avoid interference.
• Do not place the instrument in an unstable position.
• Remove all connected adaptors and cables before moving.
• Clean with a soft, dry cloth. Do not use thinners, solvents, or chemical cloths. Do not place vinyl/plastic/rubber objects on the instrument.
• Do not rest weight on or place heavy objects on the instrument. Do not use excessive force on buttons, switches, or connectors.
• Use only the specified stand/rack and provided screws.
• Do not operate at high or uncomfortable volume levels for extended periods to prevent hearing loss. Consult a physician if hearing loss or ringing occurs.

Battery Notice:

• The instrument contains a non-rechargeable internal backup battery for data storage. When "Battery Low" displays, back up your data and have qualified Yamaha service personnel replace the battery. Do not attempt self-replacement.
• Keep batteries away from children. If swallowed, consult a physician immediately.

Saving User Data: Save all data to an external device (e.g., Yamaha MIDI Data Filer MDF3) to prevent data loss. Yamaha is not responsible for damage caused by improper use or modifications, or lost data.

Environmental Issues: Yamaha strives for user safety and environmental friendliness. Dispose of batteries and products responsibly according to local regulations.

Name Plate Location: Model number and power requirements are on the top panel; serial number is on the rear panel. Record these details for your purchase record.

Multilingual Notice (Netherlands): This apparatus contains a lithium battery for memory back-up. Consult your retailer or Yamaha Service Department for battery removal upon disposal. Do not throw away the battery; hand it in as small chemical waste.

Lithium Caution (Nordic/Baltic languages): Warning: Lithium battery – explosion hazard if handled incorrectly. Replacement must only be with the same manufacturer and type. Return used battery to the supplier.

Setting Up

Ensure power is OFF on all devices before making connections.

Connecting the Pads

Connect pad output cables to the rear panel Trigger Input Jacks (1 KICK to 8 HI HAT, 9/10). Jacks are labeled for corresponding pads. Stereo pads are compatible. The DTXPRESS automatically assigns settings for labeled inputs, but manual adjustment of sensitivity (via [TRIG] button and Trigger Setup Edit mode) may be needed for different pad characteristics.

Input Attenuation Switch: 'L' position for low sensitivity pads (TP, KP, PCY, BP); 'H' position for high sensitivity (DT10 Drum Trigger).

Special Notes:

• The [1 KICK] jack can accept pads like TP60, TP80S, PCY80S, or Hi-Hat Controllers (HH60, HH80, HH80A) used as a kick pedal (configure via [1-1. Pad Type]).
• The [9/10] jacks can connect a second bass drum pedal for double-bass setups. These stereo jacks (L=9, R=10) support 2-trigger input. A conversion cable can split a stereo plug into two monaural plugs for two separate trigger signals.

Setting up with Acoustic Drums

Attach optional Yamaha DT10 Drum Triggers to acoustic drums. Connect triggers to the DTXPRESS rear panel jacks. Ensure suitable settings are made in the Trigger Setup Edit mode ([1-1. Pad Type]).

Attaching Drum Triggers: Mount sensors on the batterhead near the rim (avoiding contact with the rim) for bass drums and toms, or on the shell near the rim for toms. Ensure the sensor does not contact the rim or other instruments.

Removing Drum Triggers: Carefully remove sensors with a knife before loosening the head. Avoid pulling the cord.

Taking Care of Drum Triggers: Clean surfaces with alcohol before mounting. Secure sensors and cords with tape to prevent damage from vibration. Use Yamaha Ring Mutes to prevent double-triggering from irregular vibrations. Use new tape when remounting.

Connecting a Mixer or Audio Equipment

Connect DTXPRESS [OUTPUT L/MONO] and [R] jacks to a mixer or audio equipment for external speaker playback or recording. Use the appropriate cables for your equipment.

Connecting a MIDI Device

Connect DTXPRESS [MIDI OUT] to external device [MIDI IN] (or vice versa) using MIDI cables. Set [HOST SELECT] to "MIDI". This allows data storage (Bulk Dump), control of the DTXPRESS by external sequencers, and transmission of DTXPRESS performance data.

Use standard MIDI cables, no longer than 15m, to avoid irregular operation.

Connecting a Computer

Connect the DTXPRESS [TO HOST] jack directly to a computer's serial port using a compatible serial cable. Set the [HOST SELECT] switch accordingly (Mac/PC-1/PC-2). This enables use of sequencer software for controlling DTXPRESS voices and editing sequence data.

Connecting a CD Player, etc. (AUX IN jack)

Connect a CD player or cassette deck to the front panel [AUX IN] (stereo mini) jack. The audio output mixes with the DTXPRESS sound and is sent to the output jacks. Adjust the external audio volume using the [AUX IN VOL] knob.

Connecting a Pair of Headphones (PHONES jack)

Connect headphones to the front panel [PHONES] jack. Adjust headphone volume using the [POWER/VOL] knob. Be mindful of hearing protection.

Connecting the Power Supply

Connect the supplied power adaptor to the [DC IN 12V] jack on the rear panel. Secure the cord using the cord hook. Use only the supplied adaptor. Unplug the adaptor when not in use for extended periods.

Before switching power ON:

• Rotate the [POWER/VOL] knob fully counter-clockwise (minimum volume) to protect speakers, headphones, and the DTXPRESS.
• Ensure all external devices connected to the DTXPRESS are powered OFF. Power on external devices after the DTXPRESS is powered ON.
