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.
Connections: Only use the connections as described. Other connec-
tions can lead to health risks and equipment damage.
Water And Humidity: Do NOT use this machine anywhere near water
(for example near a wash basin or bath, in a damp cellar, near swim-
ming pools, or the like). In such cases there is an extremely high risk of
fatal electrical shocks!
Insertion Of Foreign Objects Or Fluids: NEVER allow a foreign object
through any of the machine‘s chassis openings. You can easily come
into contact with dangerous voltage or cause a damaging short circuit.
NEVER allow any fluids to be spilled or sprayed on the machine. Such
actions can lead to dangerous electrical shocks or fire!
OPENING THE DEVICE: Open the device only to fit or exchange mod-
ules. The fitting and/or exchange of modules should only be carried
out by qualified persons. In the light of possible physical damage
or injuries any manipulation is at your own risk. In order to avoid
any residual voltage, the device should be disconnected from any
power source at least 5 minutes prior to opening it. If you handle the
device improperly or ignore the manual (part of the delivery of the
RackPack frame) you risk to damage the device or expose yourself
to an electric shock. In these cases SPL electronics GmbH denies any
responsibility.
Electrical Power: Run this machine ONLY from sources which can
provide proper power at the prescribed rating. When in doubt about
a source, contact your dealer or a professional electrician. To be sure
you have isolated the machine, do so by disconnecting the power cord
from your wall connection. Be sure that the power cord plug is always
accessible. When not using the machine for a longer period, make sure
to unplug it from your wall power socket.
Power Cord Protection: Make sure that your power cord is arranged to
avoid being stepped on or any kind of crimping and damage related
to such event. Do not allow any equipment or furniture to crimp this
power cord.
Power Connection Overloads: Avoid any kind of overload in connec-
tions to wall sockets, extension or splitter power cords. Always keep
manufacturer warnings and instructions in mind. Overloads create fire
hazards and risk of dangerous shocks!

RackPack: Full Ranger 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.
Air Circulation: Chassis openings offer ventilation and serve to pro-
tect the machine from overheating. NEVER cover or otherwise close
off these openings. NEVER place the machine on a soft surface (car-
pet, sofa, etc.). Make sure to provide for a mounting space of 4-5 cm/2
inches when mounting the machine in racks or cabinets.
Controls And Switches: Operate the controls and switches only as
described in the manual. Incorrect adjustments outside safe para-
meters can lead to damage and unnecessary repair costs. Never use
the switches or level controls to effect excessive or extreme changes.
Repairs: Unplug the machine and immediately contact a qualified
technician when you think repairs are needed – or when moisture or
foreign objects may accidentally have gotten in to the housing, or in
cases when the machine may have fallen and shows any sign of having
been damaged. This also applies to any situation in which the machine
has not been subjected to any of these unusual circumstances but
still is not functioning normally or its performance is substantially
altered.
In cases of damage to the power cord or its plug, first consider turning
off the main circuit breaker before unplugging the power cord.
Replacement/Substitute Parts: Be sure that any service technician
uses original replacement parts or those with identical specifications
as the originals. Incorrectly substituted parts can lead to fire, electri-
cal shock, or other dangers, including further equipment damage.
Safety Inspection: Be sure always to ask a service technician to con-
duct a thorough safety check and ensure that the state of the repaired
machine is in all respects up to factory standards.
Cleaning: In cleaning, do NOT use any solvents, as these can damage
the chassis finish. Use a clean, dry cloth (if necessary, with an acid-
free cleaning oil). Disconnect the machine from your power source
before cleaning.

RackPack: Full Ranger
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 tradi-
tional designs.
First there is the basic idea of specialized modules for typical instru-
ment 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 process-
ing of all instrument and vocals and an overlapping module to comple-
ment 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
we chose a graphic EQ design? For a fully parametric EQ with all neces-
sary controls there would be space for just one band on the module
front. Our 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 our idea of a holistically musical approach. We decided for 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.

RackPack: Full Ranger 9
The Full 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).
The illustration shows the correct pin-wiring of the balanced XLR sock-
ets if an unbalanced wiring is required.
Lundahl I/O Transformers
The Input and Output 1 stages may be transformer-balanced if ordered
(please refer to page 20 for detailed information). Otherwise, all
inputs and outputs are balanced electronically. Output 2 cannot be fit-
ted 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 alterna-
tives 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, LED Display
Control Elements
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.
Signal LED
The SIG. LED indicates that an audio signal reaches the input with a
level above -20 dB. This LED helps the operator especially in complex
setups to determine immediately whether the Full Ranger actually
receives any signal.
Overload LED
The OVL LED indicates a potential internal overload. It begins indicat-
ing approximately 3 dB ahead of any expected overload to leave head-
room for peak levels.
Overloads must be avoided to exclude audible distortions. The gaining
is still perfect in most cases when the OVL LED is illuminating shortly
since there’s still a headroom of 3 dB for peak levels.
Permanent illumination of the OVL LED indicates overloads with possi-
ble audible distortions. Reduce the Output Gain control if the OVL LED
illuminates permanently until the OVL LED goes out or flashes shortly.
