مقدمة
The Niles DPS1 Amplifier/Speaker A-B Selector is a passive device designed to allow users to connect two stereo amplifiers to a single pair of loudspeakers, or to connect a single stereo amplifier to two different pairs of loudspeakers. This selector provides a convenient way to switch between audio sources or speaker outputs without the need for re-wiring, ensuring a clean and reliable audio signal path.

يثبت
The Niles DPS1 is a table-top unit designed for easy integration into your audio system. Follow these steps for proper connection:
- تحديد الاتصالات: On the rear of the DPS1 unit, you will find screw terminals for two amplifier inputs (labeled 'A' and 'B') and one speaker output (labeled 'Common'). Each input/output has terminals for Left (+) and (-), and Right (+) and (-).
- تجهيز أسلاك السماعات: Strip approximately 1/4 inch (6mm) of insulation from the ends of your speaker wires. Ensure the wire strands are tightly twisted. The connectors accommodate speaker wire up to 14 gauge. For thicker wires, you may need to carefully trim some strands to fit.
- ربط مكبرات الصوت: Connect your single pair of loudspeakers to the 'Common' output terminals. Ensure correct polarity (positive to positive, negative to negative) for both left and right channels. Use a small slotted screwdriver (slightly larger than an eyeglasses screwdriver) to secure the wires firmly.
- يتصل Ampرافعات:
- Connect the speaker outputs from your first amplifier to the 'A' input terminals on the DPS1. Observe correct polarity.
- Connect the speaker outputs from your second amplifier to the 'B' input terminals on the DPS1. Observe correct polarity.
- الموقع: Position the DPS1 in a convenient location, ensuring adequate ventilation and access to the front panel switch. The unit is sturdy and can be stacked if multiple units are used.
Note on Multi-Channel Systems: The Niles DPS1 handles two channels (stereo) per unit. For multi-channel systems (e.g., 5.1 surround sound), you will require multiple DPS1 units. For a 5.1 system, three units would typically be needed: one for front left/right, one for surround left/right, and one for center/subwoofer (if the subwoofer is connected via speaker-level inputs). Ensure consistent wiring and polarity across all units.

Using the Niles DPS1 is straightforward:
- تشغيل الطاقة: Ensure both connected amplifiers are powered on and set to a low volume level.
- اختر مصدر: Use the toggle switch on the front panel of the DPS1 to select either 'A' or 'B'.
