Recent developments in sound measurement techniques have revealed the limitations
of existing graphic equalisers. The wealth of data that such equipment can provide for
the users requirements - feedback suppression, increased headroom, room equalisation/
compensation can no longer be adequately provided for with a simple graphic equaliser.
The Apex PE MKII is the solution, providing a tool which both enables maximum correction
whilst shaping the response to your specific requirements, combining a full graphic equaliser
with a complementary parametric equaliser/notch filter.
FEATURES:
Electronically balanced input with a balanced floating output stage.
All potential overload points are continuously monitored by an extremely fast "peak-peak"
overload detecter circuit, followed by a "peak-stretching" circuit for clear indication of overload
conditions.Reliablilty is the hallmark of any product, and the mechanical integrity of the components
housing is the vital prerequisite. Sophistical CAD programmes and advanced engineering concepts
have been applied to the chassis design to eliminate the stress and torsional movements which can
damage the electronics.Special attention has been given to the purity of the signal path.The musicality
of previous designs of Apex equalisers has been well appreciated by users, and the PE continues this
tradition, noise and distortion are significantly better than 16-bit digital.Fine-tuning your system is essential.
The "vernier control" provides adjustment refinement on an unprecedented scale.In the event of power failure
to the unit, a failsafe relay links the input to the output ensuring that signal continuity is maintained.

BSS Opal FCS-966 Constant Q Graphic Eq
Graphic equalisers are found in just about every sound application, from room contouring to feedback control and general audio sweetening.
Traditionally, much general eq'ing takes place on the faders alone, but this restricts the use of the faders at each end of the scale for further precision eq work. So we provided the Opal FCS-966 with separate LF and HF contour filters which can change an overall sound balance without disturbing a detailed room or loudspeaker response.
These filters are very musical gentle boost and cut shelving filters which 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 eq's
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 eq's. 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 equalised signals using the gain control.
Centre Bypass
When any eq fader is in its centre 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, we've provided three differerent 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 centre-detent on 45mm long-throw precision faders.
HP Filter

LF Contour

GAIN
Used for overall unity gain adjustment. Adjustable from - infinity to +10dB.

The class-A circuit used in the EQ-73 is similar to the eq section in the classical 1073 module, without the high pass filter. Additional frequencies have been added and the mid frequency band uses two inductors, the higher value of the second one is used for the two lowest frequencies, 160 Hz and 240 Hz, to achieve a suitable response.
The sound character is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.
The EQ-73 has stepped frequency controls that offers a wide selection of frequencies from 20 Hz to 24 kHz.
The Low and High frequency bands are shelving and the mid frequency band is of the bell type.
The control range is +/-15 dB for the two lower bands and +/- 18dB for the high frequency band.
There are separate bypass switches for all three bands.
The EQ-73 is made to be used together with one of our PRE-73 models that has an Insert jack. It can also be used with many other units that has a low level insert jack.
Combining a PRE-73 and an EQ-73, and using a UNITE rack kit to mount them together, one will get a 19-inch 1073-style unit at a low cost and with a great sound!
