The Full Ranger EQ Module is a graphic equalizer for processing the entire frequency range with passive coil filters in eight bands. It employs bell filters, each with individually optimized bandwidths, boost and cut values. The concept of the Ranger EQs for the RackPack modular system is characterized by two decisive features that separate them from traditional designs. First there is the basic idea of specialized modules for typical instrument or vocal ranges. This follows a consistently musical approach, but also the design of each filter is based upon musical demands alone. The Full Ranger makes the necessary exception in this concept to offer a module that can be both an all-round module for processing of all instrument and vocals and an overlapping module to complement the specialized Ranger EQs. The second characterizing feature follows the idea of a modular design and affects both the filter technology and the user interface. Why did SPL choose a graphic EQ design? For a fully parametric EQ with all necessary controls there would be space for just one band on the module front. SPL's graphic EQ offers eight bands, a bandwidth control is less important, and different EQ modules can be combined to configure a large and, if needed, complex EQ system. But a traditional graphic EQ with an active filter design did not seem to match their idea of a holistically musical approach. They decided on a rare technical solution: the combination of passive filters with a graphical user interface. Based upon individually specified, custom-made coils, these filter designs convince with outstanding musical qualities. Finally, the general advantage of modular systems becomes clearly obvious when planning individual systems: A vocal recording channel with RackPack modules can be configured in very specific ways, while a complex EQ system may have a completely different focus. Lundahl I/O Transformers The Input and Output 1 stages may be ordered transformer-balanced. Otherwise, all inputs and outputs are balanced electronically. Output 2 cannot be fitted with a transformer. It is actively decoupled and allows for the input signal to be split into two output signals. Channel Split The channel split option through Output 2 always provides alternatives in processing or routing of the input channel. While one output may be used directly for mixing, the second output can be routed in any other way, for example to further RackPack modules, to other effect units etc. On With the ON button you can turn the device on or off. The ON button is illuminated when the device is active. Relay hard bypass circuits ensure signals to be directly switched from input to output in the case power failures - this "Power Fail Safety" feature guarantees signal flow in any situation. Output With the OUTPUT control you can readjust levels that were changed by previous EQ settings. For example, if you have by and large applied cut values to the signal, the overall output level can be lifted again to meet the input level's value. The same of course applies vice versa: simply lower the output to compensate for boosts that may result from your processing. If source and receiving units do not display levels, rely on setting the output by ear. An A/B comparison can be made with the ON switch. Please note that differences in sound, resulting from EQ processing, should not influence your loudness judgement when setting the output level by ear. Fader The Full Ranger module offers nine fader controls. The upper eight faders control the eight frequency bands, the lowest fader controls the output stage. All faders are manufactured by Bourns and show high-grade quality specifications. Their handling is featuring a perfect balance between smoothness and resistance. All center positions are detented and all faders are illuminated to ensure safe operation also in dark environments. The Eight (8) EQ Bands Each filter is designed as bell filter with individually optimized bandwidths and boost/cut values. Each filter is regulated by a fader control. The frequency range around the center frequency can be boosted (fader to the right into direction "+") or can be cut (fader to the left into direction "-") directly. Here is a short list with examples for setting each band. This list is of course not complete or demands general validity, we just want to give some suggestions to start from. Band 1: 16 kHz Center Frequency Boost: Glitter, brilliance, air. Band 2: 10 kHz Center Frequency Boost: Brightens up, intensifies presence Cut: Can reduce sibilance Band 3: 4,7 kHz Center Frequency Boost: Improves intelligibility of singing voices, more attack for acoustic and electric guitars or deep toms Band 4: 1,8 kHz Center Frequency Boost: More bass definition and presence Cut: Reduces metal for brass Band 5: 500 Hz Center Frequency Boost: More profound vocals , clearer basses Cut: Softens snares and toms Band 6: 150 Hz Center Frequency Boost: More warmth for everything, main impact of bass instruments, fuller, fatter snares Cut: Vocals: avoids collision with bass Band 7: 90 Hz Center Frequency Boost: Fills bass area of ac. guitars, fuller floor toms, saturated depth for piano. Cut: Kick drum: makes room for bass; generally reduces booming sounds Band 8: 40 Hz Center Frequency Boost: In general fuller sounds, deep bass punch (kick drum) Cut: Reduces booming sounds and sub harmonic interferences Specifications Audio Frequency Range: 10 Hz-30.000 Hz CMR@ 1kHz: -85 dBu @ 100 Hz, -80 dBu @1 kHz THD @ 1kHz: 0,03% @ 0 dBu/0,01% @ +10 dBu Noise, A-weighted: -83 dBu Dynamic Range: > 107 dB Fast Fourier Transformation (FFT): > -85 dBu (@ 1 kHz) Input XLR connection, electronically balanced (optionally transformer- balanced) Impedance: balanced >20kOhm/unbalanced >10kOhm Max.
