2. GENERAL DESCRIPTION
The TOA DP-K1 is a 3U rack mountable Digital Audio Processor. It features an Automatic Resonance Control function that automatically generates an optimum filter curve to improve sound clarity after measuring the acoustic characteristics in architectural space. All of this function and other acoustic signal processing functions such as compressor and delay are set by a PC using the supplied setting software. The settings can be stored in the unit's internal memory and the stored settings can be recalled from the unit without connecting the PC. The setting software is included in the supplied CD-ROM or can be downloaded from our website at http://www.toa-products.com/.
3. FEATURES
• Acoustic control that improves sound clarity can be attained through simple operation.
• Signals are digitally processed, ensuring high-accuracy sound parameter settings.
• Modular construction permits flexible configuration of inputs and outputs, from 2-IN/4-OUT to 8-IN/8-OUT systems.
• Because 8 memories are built inside, stored data can be easily recalled without connecting a PC after setting completion.
• The preset knob-lock function prevents trouble resulting from wrong operation.
4. HANDLING PRECAUTIONS
• The supplied power supply cord is designed for exclusive use with the unit. Never use it with other equipment.
• Use the unit in locations where the temperature is between +5°C to +40°C (no condensation) and the humidity is less than 90%.
• The DP-K1 is a precision audio component. To prevent failure, avoid locations where the unit may be exposed to strong shocks or vibrations.
• To clean, be sure to first switch off the power, then wipe with a dry cloth. When extremely dirty, use a soft cloth dampened in neutral detergent. Never use benzene, thinner or chemically-treated towels, which may damage the unit's finish.

These function settings are performed using the dedicated setting software. For detailed descriptions of the signal processing function, read the software setting instruction manual included in the supplied CD.
7. OPERATIONS
7.1. Recalling the Preset Memory
A PC with the dedicated software installed is required for setting the unit's parameters, but preset memory can be recalled from the unit even with the PC disconnected once these setting parameters are stored into 8 memories. (For preset function settings, refer to the software setting instruction manual included in the supplied CD.) The operating procedure is as follows.
Step 1. Rotate the front-mounted preset knob to select the desired
memory number. The dots (LEDs) around the preset knob and the memory number currently recalled flash, and the number selected by the knob lights.
Step 2. Press the preset knob to recall the preset memory of the
selected number. The LEDs stop flashing and only the selected memory number lights.
Notes
• When the preset knob remains unpressed for 60 seconds or more, the memory is not renewed, and so the original memory number stays as it is.
• The preset knob cannot be used during setting change while the PC is in communication with the DP-K1.
7.2. Locking and Unlocking the Preset Knob
You can lock the preset knob to prevent accidental wrong operation.
Hold down the preset knob on the front panel for 5 seconds or more to lock the knob.
The preset knob locks after the dots (LEDs) around the knob have flashed 3 times.
Hold down the preset knob for 5 seconds or more in locked state to unlock the knob.

10. RACK MOUNTING
Mount the unit in an equipment rack using the supplied rack-mounting screws.
Note
The supplied rack mounting screws are special screws for the TOA equipment rack. They cannot be used for other racks.
Cautions
• Install the unit as far as possible away from amplifiers or other equipment that generate heat.
• The socket-outlet shall be installed near the equipment and the plug (disconnecting device) shall be easily accessible.
• When installing the unit in an equipment rack, pay attention not to block the ventilation slots on the unit's bottom. It is recommended that a Perforated panel of over 1-unit in size be mounted directly below the unit as shown below.
9. RESTORING FACTORY DEFAULT SETTING
Step 1. Switch off the unit's power.
Step 2. Switch on the power while holding down the
preset knob. All input channel indicators light up.
Step 3. After 5 seconds, release the preset knob when the
indicators extinguish and all output channel indicators light up. The internal parameter is restored to the factory default setting.
Note
The network settings are not initialized.
Attentions
• Installer l'appareil aussi loin que possible des amplificateurs ou autres équipements générant de la chaleur.
• La prise doit être installée à proximité de l'équipement et la fiche (dispositif de déconnexion) doit être facilement accessible.
• Lors de l'installation de l'appareil en bâti, veiller à ne pas obstruer les évents de ventilation sur le dessous. Il est recommandé de monter un panneau perforé plus grand que l'appareil directement sur ce dernier, comme indiqué ci-dessous.
