1. Танилцуулга

Thank you for choosing the PROEL DBA1CH Active Direct Box. This manual provides essential information for the safe and efficient operation of your device. The DBA1CH is designed to convert unbalanced, high-impedance instrument signals into balanced, low-impedance signals suitable for direct connection to mixing consoles or audio interfaces, minimizing noise and signal degradation over long cable runs.

2. Аюулгүй байдлын мэдээлэл

Please read and understand all safety instructions before operating the DBA1CH. Retain this manual for future reference.

• Эрчим хүчний эх үүсвэр: The unit can be powered by two internal 9V batteries, a 12Vdc adapter (not included), or +48V Phantom Power from a connected mixer. Ensure the correct power source is used.
• Батерей суурилуулах: When installing batteries, ensure correct polarity. Remove batteries if the unit will not be used for an extended period to prevent leakage.
• Байгаль орчин: Do not expose the unit to rain, moisture, extreme temperatures, or direct sunlight. Operate in a dry, well-ventilated area.
• Үйлчилгээ: Энэ төхөөрөмжийг өөрөө засварлах гэж бүү оролдоорой. Бүх үйлчилгээг мэргэшсэн үйлчилгээний ажилтнуудад шилжүүлээрэй.
• Цэвэрлэгээ: Зөвхөн хуурай даавуугаар цэвэрлэ. Шингэн цэвэрлэгч, аэрозоль хэрэглэж болохгүй.

3.1 Урд самбарын онцлогууд

• DBA1CH Input (6.3mm Jack): Unbalanced input for connecting instruments or line-level sources.
• Link Output (6.3mm Jack): Parallel output of the input signal, typically used to feed an instrument ampнастан.
• Unbalanced Output (6.3mm Jack): An additional unbalanced output.
• Balanced Output (XLR): Balanced low-impedance output for connecting to a mixer or audio interface.
• PAD солих: Attenuates the input signal by +20dB to prevent clipping when connecting high-output sources.
• GND LIFT Switch: Disconnects the ground connection between the input and output to eliminate hum and ground loops.
• Эрчим хүчний индикатор LED: Төхөөрөмжийг асаах үед асдаг.

4. Тохиргоо

4.1 Төхөөрөмжийг тэжээх

The DBA1CH can be powered in three ways:

1. 9V батерей: Insert two 9V batteries into the battery compartments, ensuring correct polarity. (Batteries not included).
2. 12Vdc Adapter: Connect a compatible 12Vdc power adapter (not included) to the DC input jack.
3. +48V Phantom Power: If connected to a mixer with phantom power, the unit will automatically draw power from the XLR output.

4.2 Үндсэн холболт

Follow these steps for a typical setup:

1. Хөгжмөө (жишээ нь гитар, басс, даралтат хөгжим) холбоно уу DBA1CH Input using a 6.3mm mono jack cable.
2. (Заавал биш) холбоно уу Холболтын гаралт to your instrument amplifier if you wish to monitor your sound on stage.
3. -г холбоно уу Balanced Output (XLR) to a microphone input on your mixing console or audio interface using an XLR cable.
4. Ensure the mixer's phantom power is enabled for the corresponding channel if you are using phantom power.

5. Ашиглалтын заавар

5.1 PAD Switch Usage

The PAD switch is used to attenuate the input signal by +20dB. Engage this switch if you are connecting a high-output source (e.g., active bass, keyboard, or line-level output) and notice distortion or clipping at the mixer input. For most passive instruments, leave the PAD switch in the "Normal" (off) position.

5.2 GND LIFT Switch Usage

The GND LIFT switch helps eliminate hum or buzzing noises caused by ground loops. If you hear unwanted noise in your audio signal, try engaging this switch. If the noise persists or worsens, return the switch to its original position.

6. Засвар үйлчилгээ

• Цэвэрлэгээ: Төхөөрөмжийн гадна талыг цэвэрлэхийн тулд зөөлөн, хуурай даавуу ашиглаарай. Зүлгүүрийн цэвэрлэгч, уусгагч эсвэл лав бүү хэрэглэ.
• Зай солих: If using battery power, replace batteries when the power indicator LED dims or the audio signal becomes weak or distorted. Always replace both 9V batteries simultaneously.
• Хадгалах: When not in use, store the unit in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries.
