New V2.06 Firmware brings exciting new performance standards!

The one loudspeaker management system that really satisfies all your system requirements just got even better!. New V2.06 firmware introduces the first pro audio implementation of WHISEWORKS - NTM™* filter technology, which means that you can take your loudspeakers closer to their operating bandwidths without fear of over-excursion.

Find out all about the WHISEWORKS - Neville Thiele Method™ filters in the special area here.

One FDS-366 can drive a true stereo 3-way system, or 3 bi-amp outputs for monitors. Add more units and MIDI slave linking to make stereo 4, 5 and even 6-way systems.

Typical applications:

  • Stereo 3-way.
  • Stereo 2-way plus sub from input C.
  • Triple Bi-amp for stage monitors, with delay and EQ.
  • Dual tri-amp for stage monitors.
  • 96kHz Studio monitoring systems.
  • LCR Monitoring systems (post-production).
  • 6-way systems.
  • 4-way plus 2 full range outputs with separate delay and EQ.
  • 6-way Zoning ( full range outputs, giving delays, EQ and limiters on all zones )

"The new filters allow me to put more power to the devices without fear of overload or over-excursion. Once adjusted, sounds better than standard filters. The system seemed louder and clearer. We were setting off alarms in the car park!"
Ferrit, Promix/Electrotec, Las Vegas, Nevada, USA

Other applications are also satisfied, such as zoning to six discrete areas using full range or band-restricted outputs. As a mono sum of all three inputs is available, the FDS-366 will find favour with LCR post-production monitoring systems where a mono sub output is required. A stereo AES/EBU digital input also means that the FDS-366 is an ideal product for studio monitoring applications.

BSS have incorporated the very latest digital technology and DSP algorithms to provide the COMPACT plus with a truly astonishing audio performance. The latest generation of 24-bit converters with carefully engineered support electronics provides a dynamic range in excess of 112dB (unweighted) without employing 'massaging' techniques that could have side effects.

Using a 96kHz sample rate further enhances the sonic performance of the FDS-366. The advantages of this higher rate mean a more natural and open sound thanks to a 40kHz bandwidth and improved filter responses that are possible with the higher Nyquist frequency.

BSS Audio pioneered the use of dynamic equalisation on the DPR-901, a tool well known to engineers the world over. Essentially a way of compressing selected frequencies when the signal reaches a pre-set threshold, adding dynamic eq to every input and output on the FDS-366 provides the engineer with a way to control some of the non-linearities in drivers (such as 2" horns) and room resonance's.

Two new facilities, the 'Alignment Assistant' and Dynamic EQ, help to reduce setup time and enhance creativity.

The effects of non-identical delays between loudspeaker drivers in cabinets, and between cabinets are well known. The FDS-366's Alignment Assistant makes the calculation and implementation of driver delay settings quick and automatic. A microphone input directly measures and corrects for driver and cabinet displacement, and also takes into account inherent phase shifts present in these and other system elements.

ARCHITECT'S AND ENGINEER'S SPECIFICATION

FDS-366T OMNIDRIVETM COMPACT plus Loudspeaker Management System

The Digital Crossover System shall be configurable from a combination of three inputs and six outputs, in a single 1U rack-mounting unit, each output having facilities for crossover, parametric EQ, dynamic EQ, mid-filter limiters, and delays. Each input must have facilities for parametric EQ, dynamic EQ and delays. Any output may take its feed from any input, including a mono sum of the first two inputs, or a mono sum of all three inputs. All functions must be accessible through front-panel switches and controls or remotely via a personal computer. The unit shall have electronically balanced analogue inputs and outputs.

Transformer isolation shall be available as an internally fitted option for the outputs.

A stereo digital AES/EBU input shall be provided which shall accept sources with sample rates of 96kHz, 88.2kHz, 48kHz or 44.1kHz.

All data shall be displayed both numerically and graphically to provide a visual reference of crossover points, delay times, EQ curve and system performance. Individual LED meters shall be provided on each input and output, together with an output trim control and mute facility. LED indicators shall also show when clipping levels are approached.

The system shall have a facility for automatically calculating and adjusting inter-driver alignment delays using a microphone connected to an input.

Each crossover output band shall be selectable to operate with a slope of 6, 12, 18, 24, 26, 48 or 52dB per octave. The filter types available shall be Butterworth, Bessel, Linkwitz-Riley or NTMTM*. Each band shall have polarity inversion switching and phase adjustment at each crossover point. Each band shall be adjustable for both high and low-frequency roll-off points, individually or in crossover pairs.

Each input and output shall have freely assignable parametric EQ, each EQ section having a centre-frequency range of 15Hz to 20kHz, with adjustable gain of +/-15dB, and a variable Q adjustment of 0.05 to 3.00 octaves. The filter shape shall be selectable between bell or shelving, with selectable shelving slopes of 6dB or 12dB per octave.

Each output shall have threshold adjustable mid-filter limiters, with threshold adjustment of -10dBu to +20dBu, viewed and set in mV or dBu. There shall be brick wall limiting with adjustable overshoot.

Each input and output shall have a delay line, adjustable up to 2.6 seconds in 11 microsecond steps. Delay settings should be set and viewed in milliseconds, feet or metres. It shall be possible to link bands for relative delays.

There shall be no less than 50 memories for the storage of system data, with a facility to store such data on a PC memory card directly from the unit. It shall also be possible to output memories via MIDI to a MIDI storage device.

Password protection shall optionally disable the setting and viewing of parameters by non-authorised personnel.

There shall be provision for remote control via MIDI, RS-485 or RS-232, and it must be possible to update system software via MIDI or RS-232.

The Digital Crossover System shall be the BSS Audio FDS-366T OMNIDRIVE(TM) COMPACT plus.
