High-Pass Filter Bypass
When activated, the High-Pass Filter
Bypass (Section 3.1) allows the full-
range signal to be sent to the local
(amplifi ed) Channel 1 and Channel 2
outputs, while still providing fi ltered
low-frequency output to the Mono Summed Male XLR Output. This
confi guration works well if you have
full-range speakers driven by the
main amplifi er, plus a sub on an
auxiliary amp for sub-bass output.

3.4 Specifi cations
Note: Specifi cations describe typical results
using the module installed in a Crown SST-
compatible amplifi er. All measurements are
in Stereo mode with 8-ohm loads and an
input sensitivity of 26-dB gain at 1-kHz
rated power unless otherwise specifi ed.
Specifi cations for units supplied outside
the U.S.A. may vary slightly at different AC
voltages and frequencies.
Performance
Frequency Response: ±0.1 dB
from 20 Hz to 20 kHz at 1 watt.
Signal to Noise Ratio,
A-Weighted:
Better than 105 dB
below rated 1-kHz power;
20 Hz to 20 kHz: Better than 100
dB below rated 1-kHz power.
Total Harmonic Distortion (THD):
1-kHz rated power, 1.0% or less
true THD from 20 Hz to 20 kHz.
Crosstalk: Better than 50 dB below
rated power, 20 Hz to 20 kHz.
Input/Output
Input Impedance: Nominally 20 k
ohms, balanced. Nominally 10 k
ohms, unbalanced.
Output Impedance: 600 ohms,
balanced.
Maximum Output: +15 dBm into
600 ohms.
