Notes

1. Measured 1 meter on axis to high horn, half-space conditions, pink noise input, in third-octave bands.

2. Loudspeaker drive with "A" weighted noise (peak-to-RMS ratio approximately 12 dB), with amplifier rated at 600 W/channel at 8 ohms. The MSL-2A will accommodate amplifiers capable of output levels up to ▒140 vpk.

3. ISO™ input: Pins 1, 2 and 3 are transformer isolated, shell is connected to chassis/AC mains ground.

4. "A" - weighted, unbalanced.
