Setup
1. Placement
Place the speakers on a stable, flat surface. For optimal stereo imaging, position them equidistant from your listening position and spaced appropriately apart. Ensure adequate ventilation around the speakers.
2. Connecting the Speakers
- Identify the active speaker (with controls and input ports) and the passive speaker.
- Connect the active speaker to the passive speaker using the provided interconnection cable. This cable typically has a 3.5mm plug for treble and an RCA plug for bass on one end, connecting to corresponding ports on the passive speaker.
3. Connecting to Audio Source
The Sykik Pro speakers support two main connection methods:
RCA Audio-In (Wired Connection)
- Locate the RCA Audio-In ports on the back of the active speaker.
- Connect your audio source (e.g., turntable, TV, computer) to these ports using an RCA cable. Ensure the left and right channels are correctly matched.
Bluetooth (Wireless Connection)
- Ensure the speakers are powered on.
- Activate Bluetooth on your audio device (e.g., smartphone, tablet, computer).
- Search for available Bluetooth devices. The speakers will appear as "Sykik Pro" or a similar name.
- Select the speakers to pair. A confirmation sound may indicate successful pairing.
4. Power Connection
Connect the power adapter to the active speaker's power input, then plug the adapter into a standard electrical outlet.
Operating Instructions
Power On/Off
Use the power switch, typically located on the active speaker, to turn the speakers on or off.
Volume Control
Adjust the master volume using the dedicated volume knob on the active speaker. You can also control the volume from your connected audio source.
Bass and Treble Adjustment
The speakers feature separate bass and treble controls. Use these knobs to fine-tune the audio output to your preference or room acoustics.
Input Selection
If your speakers have an input selection button or switch, use it to toggle between RCA Audio-In and Bluetooth modes.
