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.

Scope Of Delivery

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.

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

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.
