BSS Audio DPR-901ii Dynamic Equalizer
The DPR-901ii is a 4-band parametric equalizer which varies the degree of equalization dynamically, as the program level changes. The process can be thought of as frequency selective compression and/or expansion, but it is fundamentally different to simple 'frequency-conscious' dynamics processing as used for noise gating, de-essing and the like. It is also very different to the growing family of 'sliding filter' techniques used in single-ended noise reduction processors. A split facility allows the unit to be used as 2 separate 2-band units, and a side chain listen button allows monitoring of the filter setup.Frequency selective compression is equivalent to applying CUT on a normal equalizer while frequency selective expansion is like applying BOOST. However, the DPR-901ii can be more subtle as the process is dynamic: it will only occur above (or below) the threshold you have set. Some possible uses for the DPR-901ii technology can be: •To selectively compress and/or expand, broad or narrow-band segments of program. •To de-ess and de-pop. •To add dynamic loudness control (eg. bass boost at low SPLs). •To control SPL in a dynamic and frequency conscious manner. •To enhance or 'sweeten' mixed programme. •To improve voice intelligibility (without risking howlround or feed-back). •To enhance low level vocals. •To correct for and/or guard against, bad microphone technique (by unskilled performers). And in common with other units in BSS Audio's processor range, the DPR-901ii features: •Friendly rotary control knobs for all parameter adjustments. •Excellent low level resolution to maintain subtle musical detail. •Minimum phase and low group delay for any EQ setting. •High headroom >+ 20dBu. •Conservative drive capability into low impedances (down to 600 ohms) and long, highly capacitive cables. •Automatic relay controlled signal bypass if mains power is disconnected or fails. Altogether, the DPR-901ii will not degrade a conventional high quality analogue signal processing chain, even when two units are inserted in line with the composite stereo mix....details

BSS Audio AR-133 Active DI Box
The AR-133 Active DI Box from BSS Audio uses an enhanced version of the same audio path as the AR-116, now regarded by many people as a reference standard. The sound quality is legendary, particularly on acoustic and bass guitars. Numerous applications can be satisfied by the AR-133. For example, as well as the traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources. An additional bonus is the ability to use the AR-133 as an active balancing device.Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning that the AR-133 can be used to convert unbalanced signals to a balanced output on XLRs throughout. The arched case allows cables to run back underneath the unit from the end for neat cable management. Input attenuation is 0, -20 or -40dB, making the box suitable for instrument, line or amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick solutions to ground-loop problems.The BSS AR-133 includes phantom power and battery supplies as standard. Should the phantom power from the console fail or be accidentally switched off, the AR-133 automatically switches over to the internal 9V battery providing uninterrupted use. This unit is housed in a rugged aluminum extrusion case, with robust polyurethane end-cheeks which give the AR-133 a very distinctive look....details

BSS Audio Opal FCS-966 Graphic Equalizer
BSS Audio provides the Opal FCS-966 Constant Q Graphic Equalizer with separate LF and HF contour filters that can change an overall sound balance without disturbing a detailed room or loudspeaker response. Graphic equalizers are found in just about every sound application, from room contouring to feedback control and general audio sweetening. With the Opal Constant Q you're able to make greater use of the faders at each end of the scale for precision EQ work in a wider range of settings. These filters are very musical gentle boost and cut shelving filters that can be used to add (or remove) room effects that change with temperature, audience numbers or humidity.All these effects can be easily made without disturbing the critical fader settings already made. Constant Q Filters The modern generation of graphic EQs uses the Constant Q topology, pioneered by BSS Audio, which means that the filter width is constant whatever the fader gain setting. Compared to the earlier 'gyrator' style of filters, Constant Q filters provide a smoother and more predictable interaction between adjacent faders and the resulting EQ curve more closely resembles the actual fader positions. More Gain Control Per Filter Each EQ fader has +/-15dB of adjustable gain, more than many competitive graphic EQs. The faders are long-throw 45mm types for precision control. High-Pass Filter Also provided on the FCS-966 is a sweepable high-pass filter which can be used very effectively to restrict the low-energy output for better amplifier and loudspeaker performance. Stage monitors also benefit from the application of a high-pass filter to remove bass signals (e.g. from vocal-only wedges).Metering BSS Audio believes in providing engineers with information, and the FCS-966's 8-segment LED meter shows output level and warns of signal clipping within the EQ. When the unit is switched to bypass, the meter will read the input level, allowing accurate matching of the 'dry' and equalized signals using the gain control. Center Bypass When any EQ fader is in it's center detent position the filter is automatically bypassed for optimum performance.Input/Outputs All the inputs and outputs of the FCS-966 are electronically balanced, with optional transformer balancing. To make installation of the FCS-966 easier, there are three different interface connectors: XLR-type, 1/4" TRS jack and Phoenix/Combicon screw terminals.Relay Bypass The EQ IN buttons switch the EQ path into circuit. When switched out, or power fails, a high-quality relay switches the input signal directly to the output connectors.Control Descriptions • Faders - 30 EQ filter faders on ISO centres, each with nominal +/-15dB of gain. Positive center detent on 45mm long-throw precision faders • HP Filter - Sweepable high pass filter, frequency adjustable from OUT (flat) up to 250Hz • LF Contour - Smooth shelving filter, +/-6dB of gain at 50Hz • HF Contour - Smooth shelving filter, +...details

BSS Audio FDS-366T Omnidrive Compact Plus Loudspeaker Management System
The BSS Audio FDS-366T Omnidrive Compact Plus Loudspeaker Management System is the one loudspeaker management system that really satisfies all your system requirements, and it just got even better! It includes 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. 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.Other applications are also covered, 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 favor 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 has incorporated the very latest digital technology and DSP algorithms to provide the Compact Plus with 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 equalization 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 preset 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 resonances. 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....details

Minidrive provides all four core functions of the Omnidrive range: crossovers (Linkwitz-Riley, Bessel or Butterworth), mid-band limiters, equalisation freely assignable to inputs and outputs, and both input and output delay. However, by leaving out the more advanced features in the Omnidrive, BSS has achieved dramatically lower prices, ensuring that Minidrive is suitable for a range of applications for which an Omnidrive would simply not have been affordable.BSS Audio recommends the FDS-334T for pro audio use in the monitor rack. Up to 38 bands of filtering are available in each unit. As an added bonus, the Minidrive can be controlled by SIASoft's Smaart Live analysis program, allowing the installer or engineer to create systems with integrated measurement and processing.Individual Minidrive outputs can also be run full range. With the low price of the units, this means that they are highly suited to use as zone controllers for convention centres, ballrooms, under-balcony feeds or downfills with EQ and delay, or for replacing several traditional analogue units in an installed sound system in just one rack space. BSS has provided Minidrive with a similar user interface to its big brother the FDS-366T "Omnidrive Compact Plus".The four-arrow "navipad" allows access to menus and facilties, while push-to-select switches on the output level controls ensure fast access to channels for editing. Data is shown on a bright blue LCD display, with data entry via a parameter wheel. Input and output level meters are an immediate comfort for the engineer, and individual output band mute keys are provided. Together, these make the Minidrive more convenient and faster to set up and adjust than any DSP unit in its class.For program archiving and storage, BSS Audio recommends MINISTORE, a PC application that allows you to dump programs from your Minidrive to a PC, arrange them and download any or all programs to any similar Minidrive unit.

BSS Audio DPR-504 Quad Noise Gate
The BSS DPR-504 is a 4-channel professional noise gate which has been designed for simple and intuitive use. It incorporates modern integrated circuit technology for high packing density and long term reliability. Ingenious proprietary techniques are employed to make the engineers life easier without compromise to performance or versatility. •Four independent channels that are linkable to give either one or two stereo linked master/slave modes •Flexible parametric Key filter for frequency conscious gating with absolute precision. The parametric EQ approach provides a higher degree of control for accurately rejecting spurious unwanted gate triggers than similar shelving filters. •Key listen provides operator with the facility to hear the effect of Key side- chain EQ or other processing effect as an aid to setting up. •Dual metering system which indicates both average and peak responses simultaneously and gives the operator precise information regarding the signal levels around the threshold point. Separate 'gate open' marker LED, linked to gate dynamics, continually monitors interrelation between gate activity and the actual signal. •IN switch which allows the operator to force open the gate, in the absence of signal, to check the integrity of the signal lines, and observe set dynamics. This also functions as channel bypass. •Selectable 'Fast and auto' attack modes which have been optimized for accurate and transparent performance over the widest variety of program material. Self adjusting Auto mode deals cleanly with varying dynamics whilst a super fast mode is available for demanding percussion and synthesizer transients. •Simple to operate, combined Hold and Release control which has special audio-tapered characteristics to give subtle 'musical' envelope shaping. •Rear mounted electronically balanced XLR input and output connectors. •Rear mounted 1/4" jack socket allows access to external side-chain key input for uses such as external EQ, delay or keying by and unrelated signal....details
