4. Setup
4.1 Speaker Placement
Proper speaker placement is crucial for optimal sound quality. For bookshelf speakers, consider the following:
- Place speakers on sturdy, level surfaces, ideally at ear level when seated.
- Maintain an equal distance between the two speakers and from your listening position to form an equilateral triangle.
- Keep speakers away from corners or walls if possible, as this can overemphasize bass.
4.2 Connecting the Speakers
The AIO Twin system consists of one active speaker (with controls and inputs) and one passive speaker. They connect via a supplied speaker cable.
- Connect the active speaker to the passive speaker using the provided speaker cable. Ensure correct polarity (+ to + and - to -).
- Connect the power cable to the active speaker's AC input and then to a wall outlet.
