Installation
B General Installation Hints
Please consider besides these general hints also any product-specific hints
in the "Installation" chapter of this manual.
B1 Unpacking
Check the equipment for any transport damage. A unit that is mechanically
damaged or that has been penetrated by liquids or foreign objects must not
be connected to the AC power outlet or must be immediately disconnected
by unplugging the power cable. Repairs 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 air values are the ones at the air inlets of the unit.
• Condensation must be avoided. If the unit is installed in a location with
large variation of ambient temperature (e.g. in an OB-van), feasible
measures must be taken before and after operation (for details on this
subject, 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 or placement of
the unit on a soft support).
• The unit must not be heated up by external sources of heat radiation
(sunlight, spot lights).
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 inoperative.
If the earthing could be interrupted via the power supply (e.g. by pulling
the mains plug), an additional, permanent earthing 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).
II Date printed: 26.04.04
Class I Equipment (Mains Operation)
Installation
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
(IEC320/C13 or IEC320/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 so that
the equipment cabinet is connected to the protective earth.
For information on mains cable strain relief please refer to Appendix 2.

L (Live) Brown Black
N (Neutral) Blue White
PE (Protective Earth Green/Yellow Green
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 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 the 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 environment, as listed in the following declaration.
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.
• Use a system grounding concept that satisfies the safety requirements
(class I equipment must be connected with a protective ground conduc-
Date printed: 26.04.04 III
Installation/Maintenance/ESD
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
connected 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. commonmode choke).
• Reduce electrostatic discharge (ESD) of persons by installing an appropriate 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 suitable 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 (soap-suds).
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 corresponding chapter in the Operating and Service Instructions 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 life-span of assemblies containing such components can be
drastically reduced by improper handling during maintenance and repair
work. 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.
• When performing a repair by replacing complete assemblies, the removed assembly must be sent back to the supplier in the same packing
IV Date printed: 26.04.04
E Repair
ESD/Repair
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 who wear a wristlet that is 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 (voltage puncture) or
metallic surfaces (discharge shock hazard).
• To prevent undefined transient stress of the components 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.
Removal of housing parts, shields, etc. exposes energized parts. 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 and switched on, no
un-insulated circuit components and metallic semiconductor housings
must be touched, neither with your bare hands nor with un-insulated
tools.
Certain components pose additional hazards:
• Explosion hazard from lithium batteries, electrolytic capacitors and
power semiconductors (watch 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. safety goggles, gloves).

Appendix
Appendix 1: Air Temperature and Humidity
General
Normal operation of the unit or system is warranted under the following
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 in
the following paragraphs.
Ambient Temperature
Units and systems by Studer are generally designed for an ambient temperature range (i.e. temperature of the incoming air) of +5...+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 semiconductor 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 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 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
with 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 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
sensitive areas of the system (contacts, IC pins, etc.). Once internal condensation occurs, trouble-free operation cannot be guaranteed, independent
of temperature.
VIII Date printed: 26.04.04
Appendix
Before putting into operation, the system must be checked for internal formation of condensation or ice. Only with a minute formation of ice, direct
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 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 relative humidity
of 40% is switched off in the evening. If temperature falls below +5 °C,
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.

Appendix
Appendix 2: Mains Connector Strain Relief
For anchoring connectors without a mechanical lock (e.g. IEC mains connectors), we recommend the following arrangement:
Procedure: The cable clamp shipped with your unit is auto-adhesive. For mounting
please follow the rules below:
• The surface to be adhered to must be clean, dry, and free from grease,
oil, or other contaminants. Recommended application temperature range
is 20...40 °C.
• Remove the plastic protective backing from the rear side of the clamp
and apply it firmly to the surface at the desired position. Allow as much
time as possible for curing. The bond continues to develop for as long as
24 hours.
• For improved stability, the clamp should be fixed with a screw. For this
purpose, a self-tapping screw and an M4 bolt and nut are included.
• Place the cable into the clamp as shown in the illustration above and
firmly press down the internal top cover until the cable is fixed.

1 GENERAL
1.1 MO Recording
D424 MO Recorder
For a long time, analog tape recording has been the standard recording technology in the professional audio industry. The step into the digital audio era
has been done a few years ago with the introduction of digital tape recorders, such as DASH and R-DAT machines. Another important evolution was
pushed by the computer industry: Hard disk-based workstations record on
fast, direct-access media, which are also capable for later editing without
destroying the original information.
Beginning with the consumer format CD, a removable medium with excellent price and archiving characteristics, the optical disk became in the
meantime a reliable recording media standard, in audio and computer industry.
Taking the advantages of the above approaches:
• Well accepted and easy-to-understand surface of a dedicated audio recorder,
• Versatile and future-proof technology, based on standard data storage devices (SCSI-2),
• Removable medium with very good archiving characteristics and the capability for direct access editing,
the Studer D424-2 MO recorder has been designed to be integrated into
today's and future environments, combined with analog and digital audio
processing and automation. It is ready to follow the rapid evolution of recording technology, without neglecting the needs of the professional user.
Date printed: 19.10.01 SW V 1.6 General E1/1
D424 MO Recorder
1.2 The Medium – Magneto-Optical Disks
1.2.1 Disk Standards
The D424 MO recorder with ISO drive is equipped with a 5.25" MO drive
capable of reading and writing to the standard double-sided 5.25" disk types
listed below. Only high-quality disks should be used for the D424 application. Please contact your Studer representative for information on the recommended suppliers.
1.2 GB (512 bytes/sector) available on request
2.3 GB (512 bytes/sector) available on request
1.3 GB (1024 bytes/sector) available on request
2.6 GB (1024 bytes/sector) Order No. 15.622.260.13
4.8 GB (1024 bytes/sector) available on request
5.2 GB (2048 bytes/sector) available on request
The D424 will automatically recognize the type of the disk being inserted.
Direct-overwrite (LIM-DOW) type disks are only supported when the D424
is equipped with a F-541-DW drive.
1.2.2 Disk Formatting
New disks are preformatted from the manufacturer. This process is called
“low-level formatting”. It is only useful after having cleaned a disk which
had numerous defective blocks. Low-level formatting will then re-check
every bit on the disk for validity, which can take up to 40 minutes.
In order to start recording, the D424 only has to add the basic system files.
Building up a DOS system and installing the basic D424 files is called
“high-level formatting”, or simply “formatting”. This process takes only a
few seconds.
After inserting a new, empty disk for the first time, the D424 will automatically ask for formatting. Any prerecorded disk may be re-formatted at any
time. This is a fast and direct way to delete the whole contents of a disk.
E1/2 General SW V 1.6 Date printed: 19.10.01
1.2.3 Disk Capacities
Notes: All 5.25" disks are double-sided. Each side provides the stereo capacity
D424 MO Recorder
Depending on disk type, sampling rate, and recording format, the recording
capacity will vary. The following table shows some examples of the recording capacities (stereo, per side):
Disk type 44.1 kHz / 16 bit 48 kHz / 16 bit 48 kHz / 24 bit
1.2 GB ISO 55 min 50 min 34 min
1.3 GB ISO 60 min 55 min 37 min
2.3 GB ISO 1 h 45 min 1 h 37 min 1 h 5 min
2.6 GB ISO 2 h 1 h 50 min 1 h 15 min
4.8 / 5.2 GB ISO 3 h 15 min 3 h 2 h
listed above.
Because of the DOS operating system, a maximum of 2 GB can be used;
4.8 and 5.2 GB disks are automatically formatted with a maximum partition.
With 1.2 and 1.3 GB disks, the insert recording modes are limited to 16 and
20 bit resolution. For assemble recording and editing there is no such limitation.

D424 MO Recorder
1.2.4 Disk Handling
Disks can be write-protected by sliding the appropriate tab to the “data
protect” position (see manufacturer's information).
DATA PROTECT
The magneto-optical medium is very reliable. Nevertheless, there are some
recommendations for disk storage and handling:
• Always store a disk in its case.
• Keep the disk cartridges away from sources of heat, excessive dust, or
moisture.
Please, follow also the information of the disk manufacturer.
After being exposed to a dusty environment, some blocks may be marked as
defective during recording. The MO drive will automatically assign spare
blocks for storing the affected audio information.
The D424 will check a disk when set to RECORD READY. A warning
message will be displayed if more than 60 grown defective sectors were
found.
When starting with a new production, empty disks should not report any
defective blocks. It is therefore recommended to clean empty disks with appropriate tools when encountering such warning messages. After a subsequent low-level formatting process, the disk will again be in perfect shape
for further recordings.
If the number of reported defective blocks is increasing notably, any further
recording and editing should be avoided. Backup your data before resuming
your session.
Please contact your disk supplier or Studer for detailed information on accessories as disk cleaning kits.

1.3 File Systems, File Formats, Audio Files
The D424 MO-recorder is based on a SCSI-controlled magneto-optical
drive, and standard ISO disks as storage medium. The same drives and disks
are used in computer applications for storing and archiving.
By using the same file system and formats as MS-DOS based computer
platforms, disks which were recorded with a D424 can be played by all
DOS based systems – from simple multimedia computers to fully professional audio workstations.
The D424 is storing all audio information to sound files in standard Microsoft Wave format (*.WAV), including all relevant recording parameters, as
sampling rate, word length, and number of channels.
All further information on the structure of a session as well as all editing
information are kept in separate sequence files (*.seq), also known under the
name Edit Decision List (EDL).
1.3.1 Takes, Indices, and Sequences
D424 MO Recorder
When working with the D424, you don't have to care for sound files, directories, or disk structures and the like; the following definitions, however, are
important for your recording, editing, and playback work.
The recorded material is subdivided into takes and indices.
• Every time you start recording, a new take is created.
• Place additional take markers during a long recording session. In a concert
you may mark the begin of a new song. This will save time for creating the
definitive markers when editing later.
• Store additional index markers at positions which have to be edited. Later,
you will be able to address them directly, without the need for searching.
• During the subsequent editing session, all markers having been previously
set can be deleted or moved. New ones can be set in order to prepare your
project for transferring to a CD, with all desired take and index markers.
When you start working with a new project, all settings and editing information will be stored to the currently selected sequence. Only one sequence
can be active at a time, which is called the “Current Sequence”.
• When you start recording on a new disk, a first sequence will be created.
You will stay with this first sequence until you switch to a new one.
• Create a new, empty sequence for a different project. Start recording and do
your editing session in a separate environment. It is very easy to switch between different sequences.
• You can have several sequences for a single project – do your basic editing
first, copy the current sequence to a new one, and continue with your session. You will have access to the basic version at any time.
• Make different versions of an original recording. You can decide at the end
of your projects, which one you would like to keep – or keep all of them.
Sequences do not require much storage capacity.
Date printed: 19.10.01 SW V 1.6 General E1/5
D424 MO Recorder
Takes, Indices: Insert a new, empty disk, set the channels ready, and press REC+PLAY.
The first take in the initial sequence 1 will be recorded. Each time you start
recording, a new take is created, which is given a numbered take marker at
its beginning automatically.
After having recorded three audio takes, the contents of the disk will look
like this:
1 2 3
take 1 take 2 take 3
The current sequence now consists of three takes. Simply record one more
take, and you will end up with:
1 2 3 4
take 1 take 2 take 3 take 4
Whenever there is a need for marking certain points within a take, or to
subdivide a single take into smaller parts, you can create indices by freely
placing index or take markers anywhere within your sequence, either on-line
during recording, or later when editing.
Take 2 can be divided into two separate takes by placing an additional
marker. The new take marker gets number 5, which is the next free number
in the current sequence. In addition, a certain position in take 4 is marked
with an index.
1 2 5 3 4.1 4.2
take 1 take 2 take 5 take 3 take 4
After having placed these markers, you can not only skip from one original
take to the next one, like with a CD player, but also skip to the new markers.
In the example above, the skip sequence is: 1 – 2 – 5 – 3 – 4.1 – 4.2
All the markers can simply be deleted if they are not required anymore. In
case of deleting the take markers 3 and 5 in the above example, the takes 2,
5, and 3 would be joined to a new take. The result would be like this:
1 2 4.1 4.2
take 1 take 2 take 4
Finally, markers can be moved, to adjust the take structure of the existing
source material, e.g. to define the position of the tracks and indices of a CD,
or to prepare precise start positions for on-air broadcasting.
After moving the begin of take 2, the above sequence will look like this:
1 2 4.1 4.2
take 1 take 2 take 4
E1/6 General SW V 1.6 Date printed: 19.10.01
D424 MO Recorder
Sequences: If it is necessary to make another production with the same recorded mate-
rial, a new sequence is defined. In the following example, only the takes 2,
3, and 4 should be edited, but in reverse order.
1 2 3 4
take 1 take 2 take 3 take 4
For this purpose, create a new sequence with the Sequence Editing feature,
insert the required takes in their new order (takes 4, 3, and 2), and the new
sequence will be:
4 3 2
take 4 take 3 take 2
You can now start with further editing, like changing markers, renumbering,
cutting or re-arranging audio information, or adjusting levels.
With a few keystrokes you can switch to another available sequence on the
disk, and start playing, recording, or editing.
Note: Creating new sequences does not need additional audio file capacity on a
disk. There is only a new small EDL file, describing how to play the same
audio data in a different way.
1.3.2 Non-Destructive Editing
The D424 is providing non-destructive editing. Because all editing processes
are simply instructions on how to play the original sound files, the original
audio data remain untouched during the whole editing process.
The following processes therefore only modify the sequence data, not the
original audio data:
• Creating, deleting or moving markers.
• Deleting, erasing and inserting audio elements.
• Changing the order of takes.
• Adjusting output levels.
It is possible to have several sequences on the same disk, which represent
different variations of the same basic audio material. Each sequence stores
the editing data into its own sequence file, but will make use of the same
audio files.
Without explicitly deleting sound files, which has to be done with a separate
menu utility, the original data can be re-used at any time. It is hardly possible to delete audio data by accident.
