Conforming to this directive will minimise the risk of hearing damage caused
by long listening periods. A simple rule to follow is: The longer you listen, the
lower the average volume should be. Please take care when working with your
audio system – if you are manipulating controls which you don’t understand
(which we all do when we are learning), make sure your monitoring level is
turned down. Remember that your ears are the most important tool of your
trade. Look after them, and they will look after you. Most importantly: Don’t
be afraid to experiment to find out how each parameter affects the sound;
this will extend your creativity and help you to get the best results.

B General Installation Instructions
Please consider besides these general instructions also any product-specific
instructions in the ‘Installation’ chapter of this manual.
B1 Unpacking
Check the equipment for any transport damage. If the unit is mechanically
damaged, if liquids have been spilled or if objects have fallen into the unit,
it must not be connected to the AC power outlet, or it must be immediately
disconnected by unplugging the power cable. Repair must only be performed
by trained personnel in accordance with the applicable regulations.
B2 Installation Site
Install the unit in a place where the following conditions are met:
  • The temperature andthe relativehumidityoftheenvironmentmustbe
within the specified limits during operation of the unit. Relevant values
are the ones at the air inlets of the unit (refer to Appendix 1).
  • Condensationmustbeavoided.Iftheunitisinstalledinalocationwith
largevariationofambienttemperature(e.g.inanOB-van),appropriate
precautions must be taken before and after operation (refer to Appendix
1).
  • Unobstructedairflowisessentialforproperoperation.Airventsofthe
unit are a functional part of the design and must not be blocked in any
way during operation (e.g. by objects placed upon them, placement of the
unit on a soft surface, or installation of the unit within a rack or piece of
furniture).
  • Theunitmustnotbeheatedupbyexternalsourcesofheatradiation(sun-
light, spotlights).
B3 Earthing and Power Supply
Earthing of units with mains supply (class I equipment) is performed via
theprotectiveearth(PE)conductorintegratedinthemainscable.Unitswith
battery operation (< 60 V, class III equipment) must be earthed separately.
Earthing the unit is one of the measures for protection against electrical shock
hazard (dangerous body currents). Hazardous voltage may not only be caused
by a defective power supply insulation, but may also be introduced by the
connected audio or control cables.
If the unit is installed with one or several external connections, its earthing
must be provided during operation as well as while the unit is not operated.
If the earthing connection can be interrupted, for example, by unplugging
the mains plug of an external power supply unit, an additional, permanent
earthing connection must be installed using the provided earth terminal.
Avoid ground loops (hum loops) by keeping the loop surface as small as
possible (by consequently guiding the earth conductors in a narrow, parallel
way), and reduce the noise current flowing through the loop by inserting an
additional impedance (common-mode choke).
Installation

V
Installation / EMC
ClassIEquipment(MainsOperation)
Should the equipment be delivered without a matching mains cable, the
latter has to be prepared by a trained person using the attached female plug
(IEC 320 / C13 or IEC 320 / C19) with respect to the applicable regulations
in your country.
  BeforeconnectingtheequipmenttotheACpoweroutlet,checkthatthelocal
line voltage matches the equipment rating (voltage, frequency) within the
admissible tolerance. The equipment fuses must be rated in accordance with
the specifications on the equipment.
Equipment supplied with a 3-pole appliance inlet (protection conforming to
class I equipment) must be connected to a 3-pole AC power outlet in such a
way that the equipment cabinet is connected to the protective earth.
For information on mains cable strain relief, please refer to Appendix 2.

ClassIIIEquipment(BatteryOperationupto60VDC)
Equipment of this protection class must be earthed using the provided earth
terminal if one or more external signals are connected to the unit (see expla-
nation at the beginning of this paragraph).
B4 Electromagnetic Compatibility (EMC)
The unit conforms to the protection requirements relevant to electromagnetic
phenomena that are listed in guidelines 89/336/EC and FCC, part 15.
  • Theelectromagneticinterferencegeneratedbytheunitislimitedinsuch
a way that other equipment and systems can be operated normally.
  • Theunitisadequatelyprotectedagainstelectromagneticinterferenceso
that it can operate properly.
The unit has been tested and conforms to the EMC standards of the speci-
fied electromagnetic environment, as listed in the following declaration.
The limits of these standards ensure protection of the environment and cor-
responding noise immunity of the equipment with appropriate probability.
However, a professional installation and integration within the system are
imperative prerequisites for operation without EMC problems.
For this purpose, the following measures must be followed:
  • Installtheequipmentinaccordancewiththeoperatinginstructions.Use
the supplied accessories.
  • Inthesystemandinthevicinitywheretheequipmentisinstalled,useonly
components (systems, equipment) that also fulfill the EMC standards for
the given environment.

  • Useasystemgroundingconceptthatsatisfiesthe safety requirements
(class I equipment must be connected with a protective ground conduc-
tor) and that also takes into consideration the EMC requirements. When
deciding between radial, surface, or combined grounding, the advantages
and disadvantages should be carefully evaluated in each case.
  • Useshieldedcableswhereshieldingisspecified.Theconnectionofthe
shield to the corresponding connector terminal or housing should have a
large surface and be corrosion-proof. Please note that a cable shield con-
nected only single-ended can act as a transmitting or receiving antenna
within the corresponding frequency range.
  • Avoidgroundloopsorreducetheiradverseeffectsbykeepingtheloop
surface as small as possible, and reduce the noise current flowing through
the loop by inserting an additional impedance (e.g. common-mode choke).
  • Reduceelectrostaticdischarge(ESD)ofpersonsbyinstallinganappropri-
ate floor covering (e.g. a carpet with permanent electrostatic filaments) and
by keeping the relative humidity above 30%. Further measures (e.g. con-
ducting floor) are usually unnecessary and only effective if used together
with corresponding personal equipment.
  • Whenusingequipmentwithtouch-sensitiveoperatorcontrols,pleasetake
care that the surrounding building structure allows for sufficient capacitive
coupling of the operator. This coupling can be improved by an additional,
conducting surface in the operator’s area, connected to the equipment
housing (e.g. metal foil underneath the floor covering, carpet with conduc-
tive backing).
C Maintenance
All air vents and openings for operating elements (faders, rotary knobs) must
be checked on a regular basis, and cleaned in case of dust accumulation. For
cleaning, a soft paint-brush or a vacuum cleaner is recommended.
Cleaning the surfaces of the unit is performed with a soft, dry cloth or a soft
brush.
Persistent contamination can be treated with a cloth that is slightly humidified
with a mild cleaning solution, such as dishwashing detergent.
For cleaning display windows, commercially available computer/TV screen
cleanersaresuited.Useonlyaslightly damp (never wet) cloth.
Never use any solvents for cleaning the exterior of the unit! Liquids must
never be sprayed or poured on directly!
For equipment-specific maintenance information please refer to the corre-
sponding chapter in the operating and service manuals.
D Electrostatic Discharge during Maintenance and Repair
Caution: Observe the precautions for handling devices sensitive to electrostatic dis-
charge!
Many semiconductor components are sensitive to electrostatic discharge
(ESD). The lifespan of assemblies containing such components can be dras-
tically reduced by improper handling during maintenance and repair. Please
observe the following rules when handling ESD sensitive components:
  • ESDsensitivecomponentsshouldonlybestoredandtransportedinthe
packing material specifically provided for this purpose.
EMC / Maintenance / ESD

VII
ESD / Repair
• Whenperformingarepairbyreplacingcompleteassemblies,theremoved
assembly must be sent back to the supplier in the same packing material
in which the replacement assembly was shipped. If this should not be the
case, any claim for a possible refund will be null and void.
  • UnpackedESDsensitive components should onlybehandledinESD
protected areas (EPA, e.g. area for field service, repair or service bench)
and only be touched by persons wearing a wristlet connected to the
ground potential of the repair or service bench by a series resistor. The
equipment to be repaired or serviced as well as all tools and electrically
semi-conducting work, storage, and floor mats should also be connected
to this ground potential.
  • TheterminalsofESDsensitivecomponentsmustnotcomeinuncontrolled
contact with electrostatically chargeable or metallic surfaces (voltage
puncture, discharge shock hazard).
  • Topreventthecomponentsfromundefinedtransientstressandpossible
damage due to inadmissible voltages or compensation currents, electrical
connections should only be established or separated when the equipment
is switched off and after any capacitor charges have decayed.
E Repair
  Byremovinghousingpartsorshields,energizedpartsmaybeexposed.For
this reason the following precautions must be observed:
  • Maintenancemayonlybeperformedbytrainedpersonnelinaccordance
with the applicable regulations.
  • TheequipmentmustbeswitchedoffanddisconnectedfromtheACpower
outlet before any housing parts are removed.
  • Eveniftheequipmentisdisconnectedfromthepoweroutlet,partswith
hazardous charges (e.g. capacitors, picture tubes) must not be touched until
they have been properly discharged. Do not touch hot components (power
semiconductors, heat sinks, etc.) before they have cooled off.
  • Ifmaintenanceisperformedonaunitthatisopenedwhilebeingswitched
on, no un-insulated circuit components and metallic semiconductor hous-
ings must be touched, neither with bare hands nor with un-insulated tools.
Certain components pose additional hazards:
  • Explosion hazard from lithium batteries, electrolytic capacitors and power
semiconductors (Observe the component’s polarity. Do not short battery
terminals. Replace batteries only by the same type).
  • Implosion hazard from evacuated display units.
  • Radiation hazard from laser units (non-ionizing), picture tubes (ionizing).
  • Caustic effect of display units (LCD) and components containing liquid
electrolyte.
Such components should only be handled by trained personnel who are prop-
erly protected (e.g. protection glasses, gloves).

Appendix 1: Air Temperature and Humidity
General
Normal operation of the unit or system is warranted under the ambient condi-
tions defined by EN 60721-3-3, set IE32, value 3K3.
This standard consists of an extensive catalogue of parameters, the most
important of which are: ambient temperature +5...+40 °C, relative humidity
5...85% (i.e., no formation of condensation or ice); absolute humidity 1...25 g/
m³; rate of temperature change < 0.5 °C/min. These parameters are dealt with
in the following paragraphs.
  Undertheseconditionstheunitorsystemstartsandworkswithoutanyprob-
lem.Beyondthesespecifications,possibleproblemsaredescribedbelow.
Ambient Temperature
  UnitsandsystemsbyStuderaregenerallydesignedforanambienttempera-
ture range (i.e. temperature of the incoming air) of +5 °C to +40 °C. When
rack mounting the units, the intended air flow and herewith adequate cooling
must be provided. The following facts must be considered:
  • Theadmissibleambienttemperaturerangeforoperationofthesemicon-
ductorcomponentsis0°Cto+70°C(commercialtemperaturerangefor
operation).
  • Theairflowthroughtheinstallationmustprovidethattheoutgoingairis
alwayscoolerthan70°C.
  • Averageheatincreaseofthecoolingairshallbeabout20K,allowingfor
anadditionalmaximum10Kincreaseatthehotcomponents.
  • Inordertodissipate1kWwiththisadmissibleaverageheatincrease,an
air flow of 2.65 m³/min is required.
 Example: A rack dissipating P=800W requires an air flow of 0.8 * 2.65 m³/min which
corresponds to 2.12 m³/min.
  • Ifthecoolingfunctionoftheinstallationmustbemonitored(e.g.forfan
failure or illumination with spot lamps), the outgoing air temperature must
be measured directly above the modules at several places within the rack.
Thetriggertemperatureofthesensorsshouldbe65°Cto70°C.
Frost and Dew
The unsealed system parts (connector areas and semiconductor pins) allow
for a minute formation of ice or frost. However, formation of dew visible to
the naked eye will already lead to malfunctions. In practice, reliable opera-
tion can be expected in a temperature range above –15 °C, if the following
general rule is considered for putting the cold system into operation:
If the air within the system is cooled down, the relative humidity rises. If it
reaches 100%, condensation will arise, usually in the boundary layer between
the air and a cooler surface, together with formation of ice or dew at sensi-
tive areas of the system (contacts, IC pins, etc.). Once internal condensation
occurs, trouble-free operation cannot be guaranteed, independent of tempera-
ture.
  Beforeputtingintooperation,thesystemmustbecheckedforinternalfor-
mation of condensation or ice. Only with a minute formation of ice, direct
Appendix

XI
evaporation (sublimation) may be expected; otherwise the system must be
heated and dried while switched off.
A system without visible internal formation of ice or condensation should be
heated up with its own heat dissipation, as homogeneously (and subsequently
as slow) as possible; the ambient temperature should then always be lower
than the one of the outgoing air.
If it is absolutely necessary to operate the cold system immediately within
warm ambient air, this air must be dehydrated. In such a case, the absolute
humidity must be so low that the relative humidity, related to the coldest
system surface, always remains below 100%.
Ensure that the enclosed air is as dry as possible when powering off (i.e. before
switching off in winter, aerate the room with cold, dry air, and remove humid
objects such as clothes from the room).
These relationships are visible from the following climatogram. For a con-

1 General
1.1 Utilization for the Purpose Intended
The Studer Compact Stagebox is intended for professional use.
It is presumed that the unit is operated only by trained personnel. Servicing
is reserved to skilled technicians.
The electrical connections may be connected only to the voltages and signals
designated in this manual.
1.2 First Steps
1.2.1 Unpacking and Inspection
Your new unit is shipped in a special packing which protects it against
mechanical shock during transit. Care should be exercised when unpacking
so that the surfaces do not get marred.
Check the condition of the equipment for signs of shipping damage. If there
should be any complaints you should immediately notify the forwarding agent
and your nearest Studer distributor.
Please retain the original packing material because it offers the best protection
in case your equipment ever needs to be transported.
1.2.2 Installation
Primary Voltage The power supply unit is auto-ranging; it can be used for voltages in a range
of 100 to 240 VAC ±10%, 50 to 60 Hz.
AC Supply Connection The attached female IEC 320/C13 cable socket has to be connected to an
appropriate cable by a trained technician, respecting your local regulations.
Refer to the ‘Installation, Operation, and Waste Disposal’chapter at the begin-
ning of this manual.
Earthing This equipment must be earthed, due to the power input filter network being
connected to earth.
Some consideration must be given to the earthing arrangement of the system,
at the center of which is the frame. The frame is earthed via the power supply.
Ground loops may occur where signal processing equipment, patched to the
frame, has its signal earth commoned to the equipment chassis.
Temperature Regulations The unit must not be used in conditions of excessive heat or cold, near any
source of moisture, in excessively humid environments, or in positions where
it is likely to be subjected to vibration or dust. The ambient temperature range
for normal operation of the unit is –5 to +45 °C.
1.2.3 Adjustments, Repair, Cleaning
Danger All internal adjustments as well as repair work on this product must be per-
formed by expert technicians!
Replacing the Supply Unit The primary fuses are located within the power supply modules and cannot be
changed. In case of failure, the complete power supply unit must be replaced.
Please ask your nearest Studer representative.
Cleaning Do not use any liquids to clean the exterior of the unit. A soft, dry cloth or
brush will usually do.

1.3 Features
The Compact Stagebox is ideal for owners of Studer OnAir and Vista mixing
consoles. It is a cost-effective possibility to extend the number of (remote)
inputs and/or outputs by up to 48 analog inputs or outputs, for example.
It features a high density of I/O connections in only four rack units. The
modular unit is fully configurable, with a selection of 16-channel mic/line
input modules, 16-channel analog line output modules, 16-channel AES/EBU
in/out modules and 8-channel analog line/2×4-channel AES/EBU output
modules.
Recommended standard configuration: Compact Stagebox frame, 2 × HQ
mic/line input modules, line output module, D21m MADI HD RJ45 card,
blank panels for the D21m slots.
It also offers two expansion slots for standard Studer D21m I/O cards. The
D21m system is the I/O architecture for Studer digital mixing systems and
allows connection to most popular digital formats, including CobraNet®,
Aviom A-Net®16, EtherSound®, ADAT, Livewire®and RockNet®. A MADI
recording interface may also be fitted to the expansion slots. When using
optional D21m I/O cards, the total I/O count can be increased to 64 each.
The Compact Stagebox uses the same I/O modules as found in the Studer
OnAir 1500 and Vista 1 consoles. As a result, the combination offers more
flexibility in sharing or moving modules and I/Os if required.
When installing three mic/line input modules in the Compact Stagebox, then
providing 48 mic/line inputs in total but no outputs, analog or AES outputs
could still be obtained on D-Type connectors by installing D21m cards in the
expansion slots.
When installing cards in the expansion slots please note that the maximum
input/output capacity of the Compact Stagebox is limited to 64 in/64 out by
the MADI console link.
The Compact Stagebox is connected to the host console using either Cat5 or
optical-fibre MADI cables and also allows redundant MADI links.
