Measured outside under semi‑anechoic 'full-space' conditions with typical filter and delay
settings unless stated otherwise.
Measured on‑axis. The frequency response of the complete array is depending on the
actual signal processing parameters and air absorption (at larger distances). A typical
bandwidth is specified for the complete array under 'full-space' radiation conditions.
Levels are valid for pink noise (100 Hz to 20 kHz bandwidth) with a crest factor of 3 dB,
default EQ and minimum opening angle setting. 'Continuous' is the RMS level, 'Peak' is
the absolute peak level, both determined at the onset of the output limiter. SPL values
will vary depending upon opening angle.
For this measurement the signals at all power amplifier outputs are summed together.
Additional processing capabilities available.
Measured as the A‑weighed difference (in dB) between the maximum rms level (with pink
noise input signal) and the noise output (with no input signal present).
Maximum number that can be connected to one RS‑485 subnet, multiple subnets can be
controlled by one host PC.
