Although your new console will not make any noise until you feed it signals,
it has the capability to produce sounds that, when monitored through a monitor system or headphones, can damage hearing over time.The table below is
taken from the Occupational Safety & Health Administration directive on
occupational noise exposure (1926.52):
Safety Information
III
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.
A1 Safety Symbol Guide
For your own safety and to avoid invalidation of the warranty, all text marked
with these symbols should be read carefully.
To reduce the risk of electric shock, do not remove covers. No user-serviceable
parts inside. Refer servicing to qualified service personnel (i.e., persons
having appropriate technical training and experience necessary to be aware
of hazards to which they are exposed in performing a repair action, and of
measures to minimize the danger of themselves).
The lightning flash with arrowhead symbol is intended to alert the user to the
presence of un-insulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is intended to alert the
user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.
Headphones safety warnings contain important information and useful tips
on headphone outputs and monitoring levels.

Installation / EMC
B General Installation Instructions
Please consider besides these genera l ins truct ions al so 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 oper at io n as w el l as w hil e th e u nit is n ot op e rat ed.
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).
V
Installation
Class I Equipment (Mains Operation)
Should the equipment be delivered withou t a matching mains cable, the la tter
has to be prepared by a trained person using the attached femal e 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 Opera ti on 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 explanation 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 specified electromagnetic e nvironm ent, as listed in the follo wing decla ration. The
limits of these standards ensure protection of the environment and corresponding 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.
VI
ESD / Repair
• Use a system grounding concept that satisfies the safety requirements
(class I equipment must be connected with a protective ground conductor) 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 connected only single-ended can act as a transmi tting 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. conducting 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 conductive 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
nev
er be sprayed or poured on directly!
For equipment-specific maintenance information please refer to the corresponding chapter in the operating and service manuals.
D Electrostatic Discharge during Maintenance and Repair
Caution: Observe the precautions for handling devices sensitive to electrostatic
discharge!
Many semiconductor components are sensitive to electrostatic discharge
(ESD). The lifespan of assemblies containing such components can be drastically 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.
VII
EMC / Maintenance / ESD
• 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 opened while being switched
on, no un-insulated circuit components and metallic semiconductor housings 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 properly protected (e.g. protection glasses, gloves).

Appendix
Appendix 1: Air Temperature and Humidity
General
Normal operation of the unit or system is warranted under the ambient conditions 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 problem. Beyond these specifications, possible problems are described below.
Ambient Temperature
Units and systems by Studer are generally designed for an ambient temperature 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 operation 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 do
wn, 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 sensitive areas of the system (contacts, IC pins, etc.). Once internal condensation
occurs, trouble-free operation cannot be guaranteed, independent of temperature.
Before putting into operation, the system must be checked for internal formation 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 controlled procedure, thermometer and hygrometer as well as a thermometer
within the system will be required.
Example 1: An OB-van having an internal temperature of +20 °C and a relative humidity
of 40% is switched off in the evening. If the temperature falls below +5 °C,
the relative humidity will rise to 100% (7 g/m³); dew or ice will be forming.
Example 2: An OB-van is heated up in the morning with air of +20 °C and a relative
humidity of 40%. On all parts being cooler than +5 °C, dew or ice will be
forming.
