Important Security Information Please note and retain this information. Carefully read and follow all of the safety and operating instructions before you use the machine. Be doubly careful to follow all warnings and special safety instructions noted in this manual and on the unit. The following information refers to modules built into the RackPack frame. - Page 5 Important Security Information Lightning: Before thunderstorms or other severe weather, disconnect the machine from wall power (but to avoid life threatening lightning strikes, not during a storm). Similarly, before any severe weather, dis- connect ALL the power connections of other machines and antenna and phone/internet cables which may be interconnected so that no light- ning damage or overload results from such secondary connections.

Hook Up Fitting A Module The fitting and/or exchange of modules should only be carried out by qualified persons. Please read the manual of the RackPack frame. It contains all information needed to fit a module as well as all safety and notes and warnings. -
Page 7: Introduction
Introduction The Vox Ranger EQ Module is a graphic equalizer for the vocal 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 tradi- tional designs. -

Rear Panel/Connections XLR Sockets, Transformers, Channel Split The Vox Ranger is fitted with one XLR input and two XLR outputs for balanced operation. Pin-wiring of all XLR sockets: Pin 1 = GND, Pin 2 = hot (+), Pin 3 = cold (-) Discrete balancing stages for both in- and output provide high common mode rejection and are capable of driving long cables (depending on the capacity of the cables and the following input balancing stages). -
Page 10: Control Elements
Control Elements ON, LED Display 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. -
Page 11: Output, Fader
Control Elements OUTPUT, Fader OUTPUT Stage 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. -
Page 12: The Eight Eq Bands
Control Elements The Eight EQ Bands Each filter is designed as bell filter with individually optimized band- widths and boost/cut values. Each filter is regulated by a fader con- trol. 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. -

Page 16: Operation
Operation EQ Principles First cut, then boost: The hearing system is more used to energy reductions in a frequency range, thus boosts attract more attention. That is, a 6 dB boost is perceived to be similar in amount to a 9 dB cut. -
Page 17: Technology
Bell Filters, Passive Filters, Advantages of Passive Filters Bell Filters A bell filter boosts or cuts a chosen frequency‘s energy with a maxi- mum amplitude and a definable frequency range around this fre- quency with a fall off of up to 3 dB to both sides. The chosen frequency with the maximum amplitude is called center frequency—it takes place in the middle at the peak of the response curve. -

Option As an option, the DynaMaxx RackPack module can be fitted with input and output transformers from Lundahl. The transformer options can only be ordered by purchase, a later upgrade is not possible. Information On Lundahl I/O Transformers Transformers have a pleasant sound characteristic, especially the low end sounds rounder and more full-bodied.
