What is the BSS FDS-360 Electronic Crossover with Limiters and what configurations does it support?
The BSS FDS-360 is a 1U rackmount electronic crossover unit with integrated limiters, widely used in professional audio signal management. It can be configured as 2-way stereo, 3-way mono or 4-way mono. Crossover frequencies are selected via plug-in frequency cards, making it straightforward to adapt to different speaker system requirements without replacing the unit.
What filter type and phase adjustment does the FDS-360 use?
The FDS-360 uses 24dB/octave Linkwitz-Riley filters as standard across all output bands. Phase is continuously adjustable from 0 to 180 degrees at the corner frequency, with an additional 180-degree shift available via a polarity switch. A 24dB/octave 30Hz subsonic filter is also present on the input stage, and maximum output level is rated at +20dBm with distortion below 0.05% THD.
How do the limiters on the FDS-360 work?
The FDS-360 provides variable limiters on each output band, adjusted using switches on the rear panel. The limiter range operates in 0.5dB steps, with a moveable jumper link covering a range from -10dBv to -11dBv. Front panel LED indicators show output level and compression status for each band, giving the operator a clear view of limiting activity during use.
Who makes the FDS-360 and where does it fit in the BSS range?
The FDS-360 is made by BSS Audio, originally Brooke Siren Systems, a British professional audio brand founded in 1979 and now part of Harman Professional Solutions. BSS is known for signal processing equipment including crossovers, compressors and limiters. The FDS-360 sits in the analogue signal processing side of the range, aimed at live sound and installed audio applications requiring reliable speaker management.
What should I check when buying a used BSS FDS-360?
When buying a second-hand FDS-360, confirm which plug-in frequency cards are included, as these determine available crossover points and are specific to the unit. Check that all front panel controls and rear-panel limiter switches function correctly and that the LED indicators for each band respond as expected. The unit accepts a switched 110-220V supply, so verify the voltage setting matches your region.
