What is special about BSS Crossovers?

The 

FDS-310

 is a condensation of over ten years experience, manufacturing

the industry's most advanced active crossovers for worldwide use. The 

FDS-

310

 contains all the features required for todays sound reinforcement systems

in a compact enclosure:

• It can be configured for 2 2-way channels, or for 3-way single channel
operation.
• Crossover frequencies are easily and precisely adjustable for all applications
including sub-woofers. ANY frequency between 180Hz and 9kHz can be
selected at the turn of a knob. Additional crossover frequencies down to 18Hz
can be selected by activating internal, tamper-free switches.
• Stereo signals can be summed for driving sub-woofers in mono.
• Equalisation suiting 'industry standard' HF CD (Constant Directivity) horn/
driver combinations is factory fitted and can be immediately activated.
• All inputs and outputs are balanced for ease of system installation and
interconnection, without hums and buzzes. Additionally, for each frequency
band:
• A green LED confirms signal present.
• A red LED warns of peak clipping (overdrive).
• A MUTE switch allows each frequency band to be switched in/out as an aid
to diagnosis and setting-up.
• A calibrated LEVEL CONTROL accommodates wide variations in the
sensitivity of adjacent frequency bands.
• A POLARITY switch enables each bands' polarity (or absolute 'phase') to be
reversed (or 'inverted').
• Additional, optional internal settings are confirmed by panel LEDs.
