When Installing the Unit
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.
When the Unit is in Use
• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.
· If you detect smoke or a strange smell coming
from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of
the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to your nearest TOA dealer.
• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
When Installing the Unit
• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.
• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
• Do not block the fan exhaust vent on the unit's rear and the ventilation slots on the bottom. Doing so may cause heat to build up inside the unit and result in fire.
• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.
• Be sure to follow the instructions below when rack­mounting the unit. Failure to do so may cause a fire or personal injury.
· Install the equipment rack on a stable, hard floor.
Fix it with anchor bolts or take other arrangements to prevent it from falling down.
· Use the screws supplied with the unit to mount on
TOA's rack.
· When connecting the unit's power cord to an AC
outlet, use the AC outlet with current capacity allowable to the unit.
• Do not connect the 10/100M terminal with any cables such as a telephone line that may cause excessive voltage.
When the Unit is in Use
• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

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.

[Front]
1. Power lamp
Lights when the power switch is set to ON.
2. Preset knob
Rotating this knob recalls the preset memory. Holding down it for 5 seconds or more locks or unlocks the knob. The numbers and dots marked around the knob are LED indicators. They indicate the currently recalled memory number or communication state between the DP-K1 and the PC. For details, refer to p. 13 and 14.
3. Input channel indicators
Each indicator lights green when an input signal level is –40 dB or higher on the basis of the rated level.
4. Output channel indicators
Each indicator lights green when an output signal level is –40 dB or higher on the basis of the rated level.
5. Network connection terminal
Connects to 10 Base-T/100 Base-TX networks. (RJ45 Ethernet jack) When connecting the unit to a switching hub, use a UTP Category 5 straight through cable fitted with RJ45 connectors. When connecting the unit to a PC directly, use a UTP Category 5 cross cable fitted with RJ45 connectors.

Notes
• Make sure that the power is switched OFF before attaching or detaching modules.
• To avoid failures due to static electricity, do not touch the parts or terminals on the circuit board of both the unit and module.
• Ensure that the module is installed and secured with screws in the correct position.
• Cover idle slots with the blank panels attached to the unit as shipped by the factory.
• Two silver slotted screws at the top and bottom of the front panel are handles used for module detachment. Never rotate them because they do not function as screws.
