• уземљење: Ensure the power cord's grounding pin is always connected. Do not defeat the grounding purpose.
• Влага: Не излажите уређај киши или влази. Не стављајте предмете напуњене течношћу, као што су вазе, на уређај.
• вентилација: Обезбедите одговарајућу вентилацију. Не блокирајте вентилационе отворе. Држите минималну удаљеност од 10 цм (4 инча) од зидова или других предмета.
• топлота: Не постављајте уређај у близини извора топлоте као што су радијатори, грејни уређаји, шпорети или други уређаји (укључујући ampлифиерс) који производе топлоту.
• Каблови: Заштитите каблове за напајање од газења или пригњечења, посебно код утикача, утичница и места где излазе из уређаја.
• Сервисирање: Све сервисирање препустите квалификованом сервисном особљу. Сервисирање је потребно када је уређај оштећен на било који начин, као што је оштећен кабл за напајање или утикач, ако је течност проливена или су предмети упали у апарат, ако је апарат био изложен киши или влази, не ради нормално , или је одбачено.

3. Подешавање

3.1 Распакивање

Carefully remove the subwoofer from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Retain the original packaging for future transport or storage.

3.2 Физичко постављање

Position the subwoofer on a firm, level surface. For optimal bass response, consider placing the subwoofer in a corner or near a wall. Ensure there is sufficient space around the unit for proper ventilation, especially around the rear panel where the amplifier and cooling fan are located.

3.3 Везе

Before making any connections, ensure the subwoofer's power switch is in the OFF position and the volume control is set to minimum.

• Аудио улаз: Connect your audio source (e.g., mixer, audio interface) to the subwoofer's input connectors. The DRX-18BA features XLR Combo Female Left and XLR Female Right input connectors. Use balanced XLR cables for best performance.
• Аудио излаз: Use the 2 XLR Male L/R output connectors to link the subwoofer to full-range loudspeakers or other audio equipment. These outputs typically pass through the input signal, often with a high-pass filter applied if the HPF bypass is not engaged.
• Прикључак за напајање: Once all audio connections are made, connect the supplied power cable to the AC IN socket on the rear panel and then to a suitable grounded mains outlet.

4.1 Контроле и индикатори

• Волумен: Adjusts the overall output level of the subwoofer. Start with this control at minimum and gradually increase to the desired level.
• Прекидач: Turns the subwoofer ON or OFF. Always turn on the subwoofer last in your audio chain and turn it off first.
• Приземни лифт: Helps eliminate hum or buzz caused by ground loops. Engage this switch if you experience such noise.
• фаза: Reverses the phase of the subwoofer's output (0° or 180°). Adjust this to achieve optimal acoustic alignment with your full-range speakers, ensuring the bass frequencies are in phase.
• HPF Bypass: Engages or bypasses the internal High-Pass Filter (HPF). When engaged, the HPF typically filters out frequencies below 800 Hz from the output signal sent to linked full-range speakers.
• Индикатор напајања: Illuminates when the unit is powered ON.
• Индикатор клипа: Illuminates when the input signal is too high, causing distortion. If this light flashes frequently or stays lit, reduce the input volume from your source or the subwoofer's volume control.
