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

• קלט שמע: 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.

4.1 בקרות ואינדיקטורים

• כֶּרֶך: Adjusts the overall output level of the subwoofer. Start with this control at minimum and gradually increase to the desired level.
• מתג הפעלה: Turns the subwoofer ON or OFF. Always turn on the subwoofer last in your audio chain and turn it off first.
• מעלית קרקע: Helps eliminate hum or buzz caused by ground loops. Engage this switch if you experience such noise.
• שָׁלָב: 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.
