To date, the PA 1600X is the flagship of the series. Thus it was provided with a few special details when it comes
to features.
Unless described in detail here, the elements are present in all power amplifiers and are explained on the
preceding page.
1. Balanced XLR inputs for both channels
2. Unbalanced jack inputs for both channels
3+4. Low-pass filters
Each channel is equipped with an individually adjustable low-pass filter. Using the controls (3), the cutoff
frequency is set separately between 60 Hz and 1200 Hz for each channel. The filter has a slope of 12 dB per
octave. The BASS BYPASS switch (4) can be used to remove the filter from the signal path, in which case the
filter is inactive. The purpose of this filter is that with the filter activated, the power amplifier can be used to
drive a subwoofer directly without an external crossover. Because of its high output, the PA 1600 is especially
suitable for driving bass systems.
5. LO-CUT, Low-Cut Filter
Extremely low frequencies at the bottom end of the audible range and below can easily damage the bass
loudspeakers, especially when the power amplifier has high power reserves. Thus the PA 1600 was additionally
equipped with a low-cut filter that filters out this extremely low range. The cutoff frequency is 30 Hz with a
slope of 12 dB. The filter is inactive in the “BYPASS” position.
6. Switch for stereo or bridge mode
7+8. Loudspeaker connections for Channel 2
9+10. Loudspeaker connections for Channel 1
11. Resetable fuse
