100V line system calculator.
Total the tap settings across every group of speakers on a constant-voltage line, and see which amplifier carries them.
01 Calculate
Total the taps, first.
On a 100V line every speaker draws exactly what its tap is set to, so the connected load is the sum of those taps. Group speakers by tap setting, and the amplifier follows from the total plus 20 to 30 percent headroom.
Calculation breakdown
| Speaker group | Quantity | Tap | Group load |
|---|---|---|---|
| Speaker group 1 | 20 | 10 W | 200 W |
| Speaker group 2 | 10 | 15 W | 150 W |
| Total load | 30 | 350 W |
- Total speaker load
- 350 W 30 speakers
- Minimum amplifier
- 420 W Load + 20% headroom
- Recommended amplifier
- 455 W Load + 30% headroom
Suitable Syskonics amplifiers
The calculator provides an estimated amplifier requirement. Final system design should consider speaker configuration, impedance, line losses, headroom, installation conditions and other system requirements.
