LED AUDIO POWER METER

þ 10 x LED scale, up to 2000Wrms power measurement.

þ No power supply needed, directly driven from the loudspeaker output.

þ Four display windows included:

1. from 0.15W to 200W at 8Ω speaker, low power mode.

2. from 0.3W to 400W at 4Ω speaker, low power mode.

3. from 5W to 1000W at 8Ω speaker, high power mode.

4. from 10W to 2000W at 4Ω speaker, high power mode.

þ Ideal for car audio systems and P.A. systems

þ Can also be used with bridged power amplifiers.

þ Aluminium front panel included for easy panel mounting inside

speaker cabinet.

þ Horizontal or vertical mounting possibility.
