4.2 Placement

Place the speakers on a stable, flat surface such as a desk or shelf. For optimal stereo imaging, position the speakers equidistant from your listening position and spaced appropriately apart. Avoid placing them too close to walls or corners, which can affect bass response.

• Analog Audio Input: Connect your analog audio source (e.g., PC, smartphone, turntable with pre-amp) to the RCA stereo analog input terminals on the rear of the active speaker using an RCA stereo audio cable.
• Subwoofer Output: If you wish to add an external subwoofer, connect it to the RCA monaural subwoofer output terminal on the rear of the active speaker.
• Headphone Output: For private listening, plug your headphones into the 3.5mm stereo headphone jack on the front panel of the active speaker.
