Frequently Asked Questions
Bluetooth latency is acceptable for basic playback, but may not be ideal for live performance requiring precise timing.
While technically possible, the Stagepas 400BT's limited low-end response means a sub-bass won't dramatically improve the overall sound.
The EQ is basic, offering only simple high, mid, and low controls. More complex tonal shaping would require external processing.
