ADJ DB Display MKII Instruction Manual

1. შესავალი

The ADJ DB Display MKII is a rack-mountable decibel level display unit designed to provide a visual representation of audio signal levels within an amplifier rack or other audio setup. This device enhances the visual appeal of your audio system by displaying sound levels through a series of LED indicators that progress from green, through amber, to red, indicating increasing signal intensity. It is equipped with features for precise control and versatile connectivity, making it suitable for various professional audio environments.

2. მახასიათებლები

• თაროზე დასამონტაჟებელი დიზაინი: Specifically engineered for installation in standard 19-inch ampმაცხოვრის თაროები.
• დინამიური LED დისპლეი: Features a dual-channel (Left & Right) LED display that visually indicates decibel levels, transitioning from green (low), to amber (medium), to red (high).
• რეგულირებადი მგრძნობელობა: Independent sensitivity adjustments for both left and right channels allow for precise calibration to match various audio sources and desired display responsiveness.
• ჩვენების ორი რეჟიმი: Users can select between 'Dot' mode (single illuminated LED per level) and 'Bar' mode (cumulative illuminated LEDs up to the current level).
• მრავალმხრივი კავშირი: Equipped with both RCA and XLR line inputs and outputs for broad compatibility with professional audio equipment.
• Compact Power Supply: Operates with an included 5V DC, 500mA power supply.

3. დაყენება

Follow these steps to properly set up your DB Display MKII unit:

1. მონტაჟი: Secure the DB Display MKII into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate ventilation around the unit.
2. დენის კავშირი: Connect the included 5V DC power supply to the 'DC INPUT' jack on the rear of the unit. Plug the power supply into a suitable electrical outlet.
3. აუდიო შეყვანის კავშირი: Connect your audio source (e.g., DJ mixer, audio interface) to the 'LINE INPUTS' on the rear panel. You can use either the Left & Right RCA inputs or the Left & Right XLR inputs. Ensure connections are secure for both channels.
4. აუდიო გამომავალი შეერთება (არასავალდებულო): If you need to pass the audio signal through the DB Display MKII to another device (e.g., amplifier, recording device), connect the 'LINE OUTPUTS' (RCA or XLR) to the input of the next device in your audio chain.

4. საოპერაციო ინსტრუქციები

Once the unit is set up, follow these instructions for operation:

1. ჩართვა: Flip the 'POWER' switch on the front panel to the 'ON' position. The LED display should illuminate.
2. აირჩიეთ ჩვენების რეჟიმი: Use the 'MODE' switch on the front panel to toggle between 'DOT' and 'BAR' display modes.
   • წერტილის რეჟიმი: A single LED illuminates at the current decibel level for each channel.
   • Bar Mode: All LEDs up to the current decibel level illuminate for each channel, creating a bar graph effect.
3. მგრძნობელობის დარეგულირება: Play audio through your system. Use the 'SENSITIVITY' adjustment knobs (typically small potentiometers accessible via a screwdriver) for the Left and Right channels to calibrate the display. Adjust them so that the LEDs accurately reflect your desired audio levels, with peaks reaching into the amber or occasional red zone without consistently staying in the red.
4. Monitor Audio Levels: Observe the LED display to visually monitor your audio signal levels. Green indicates safe levels, amber suggests strong but acceptable levels, and red indicates peak levels that may lead to clipping or distortion if sustained.
