INTRODUCTION

The DSF-2 Broadcast Microphone System has been specifically developed to simultaneously
provide both the surround and stereo soundscape at large scale outside broadcast events such as
football stadiums and concert hall venues. Its advantage over alternative methods is that the multi­channel audio it generates from a ‘single point’ source is completely phase coherent. This enables
the broadcaster to collapse the surround to stereo or mono for TV and radio feeds without loss of
information, frequency imbalance or any of the other phase problems associated with spaced
microphones or multi capsule ‘dummy head’ arrangements.

All processing is in the digital domain and the 1U controller is equipped with digital 750 ohm AES
3-id outputs on BNC connectors capable of driving up to 1000m of coaxial cable (subject to
correct cable specification). When used is conjunction with the 250m SoundField mic cable, the
microphone head can be situated up to 1.25 Kilometres from the DSF-2 controller. This can be a
major benefit in situations where the OB vehicles have to be sited some distance away from the
venue or performance.

The DSF-2 outputs stereo Left/Right (digital and analogue), stereo M/S (digital only) and four
channels of SoundField B-Format called W, X, Y and Z (digital only) which is the surround sound
information. A single lightweight multiway cable is used to connect the microphone to the DSF-2
controller which as well as carrying the individual capsule signals also supplies the necessary
power to the microphone allowing unrestricted use in OB and ENG applications as well as in the
studio. All microphone parameters can be remotely adjusted from the DSF-2 controller’s front
panel whilst monitoring the results on the provided headphone monitoring.

The DSF-2 is designed to function as either a variable pattern single (mono) microphone, a
variable pattern, variable width, coincident stereo microphone array or to generate full surround
from the four B-Format outputs which will then be decoded into 5.1 by the DSF-3 Digital
Surround Processor or Surround Zone software. This is achieved using four sub-cardioid capsules
set in a regular tetrahedron, and by adding or subtracting the outputs from these four capsules in
different proportions, it is possible to derive all possible polar patterns from omni, through
cardioids to figure-of-eights.

For surround recording applications the engineer should use the four B-Format output signals.
These contain the three dimensional information (Height, Width, Depth and Sub Bass LFE)
required for all current and future surround sound formats. In live broadcast applications the B­Format outputs of the DSF-2 should be connected to the digital B-Format inputs of the DSF-3
Digital Surround Processor which will output full 5.1 surround on six discrete channels (Left,
Centre, Right, Surround Left, Surround Right and Sub-Bass). In addition to 5.1 the DSF-3 can also
output Left/Right stereo. If the surround and stereo mixing will be done at a later time in post
production the B-Format signals should be recorded on four tracks and introduced to the DSF-3 or
Surround Zone software in a studio environment.

For further information on using the DSF-2 in conjunction with the DSF-3 see the ‘Interfacing the
DSF-2 with the DSF-3 for Live Surround Broadcast’ section of this manual.

multi-microphone set-ups.

The SoundField Four Capsule Array

From a single point
source sound is received
from all directions,
reproducing a realistic
listening experience.

The four outputs from the capsules of SoundField microphones (called SoundField A-Format
audio signals) are converted by the DSF-2 processor into four components known as SoundField
B-Format. These convey all of the information of the entire sound field, and are the three
directional vectors - Left/Right, Front/Rear and Up/Down - and absolute pressure.

The signals from the four capsules are fed to the
DSF-2 processor where it is converted into four
channels of SoundField B-Format, entitled W, X, Y
and Z.

Mono, Stereo, Mid-Side, 5.1 and all future surround
formats can be derived from this information.

HOW DOES IT WORK?

SoundField B-Format:

SoundField DSF-2 User Guide

Page 6How Does it Work?

The four channels of the B-Format signal are represented by three bidirectional and one
omnidirectional pickup, all centred at a single point in space, and are labelled W (pressure), X
(Front/Rear), Y (Left/Right), and Z (Up/Down). These signals contain all of the information
required to describe a soundwave and are the essential elements needed to create any conventional
mono, stereo, or surround format where the microphone positions and polar patterns can be fully
variable. By recording the four B-Format outputs from the DSF-2 controller these components can
be preserved for subsequent production and processing of current and all future surround formats.

B-Format Illustration

B-Format is three dimensional acoustical
information and consists of three figure of eight
polar patterns called X, Y and Z plus one omni
called W.

X gives Front to Rear depth information, Y
gives Left to Right horizontal information and Z
gives vertical height information. From the omni
W sub-bass (LFE) is extracted.

SoundField are the only microphones in the
world that generate B-Format.

GETTING STARTED

WARNING: The DSF-2 microphone is not compatible with other SoundField Control Units

in the product range. SoundField Ltd will not accept any responsibility for damage caused by
the interconnection of these units.

WARNING: The DSF-2 1U digital controller should be sited in a cool operational
environment in a well ventilated rack with 1U free space above the unit.

BEFORE USE

Before applying mains power to the DSF-2 system, connect the microphone to the controller with
the interconnection cable provided. When connecting the microphone, make sure the red dot on the
Lemo Female 12 Pin In-Line Connector is aligned with the red dot at the base of the microphone
before insertion. To disconnect the cable push the disc forward on the base of the microphone and
release the connector.

When connecting the microphone cable to the DSF-2 controller, ensure the red dot is facing
upwards. To disconnect, pull back on the silver connector grip and release.

It is essential that the microphone be powered up a few minutes before use to allow the capsule
charging process to stabilise. If the microphone has been used recently, the time taken to stabilise
may be shorter, but turning the microphone on fifteen minutes or so before it is needed is a good
habit to acquire.

In conditions where condensation is likely to be a problem, for example, when bringing the
microphone from a cold vehicle to a warm venue, it is advisable to leave the microphone switched
on for up to half an hour before use so that the internal heating system can clear the capsules of all
condensation.

The DSF-2 system does not require Phantom Power (48V) if it is connected to a mixing console.
Please ensure that the Phantom Power on the mixer input channels is turned off.

Push silver disc on microphone
base at the ‘red dot’ position to
release connector.

MICROPHONE ORIENTATION GUIDE

The illustrations below show the correct status of the End-Fire and Invert switches on the DSF-2
controller relative to the orientation of the microphone.

KEYS TO PROPER PLACEMENT OF SOUNDFIELD MICROPHONES

Getting the mic in the right place is the first step in making a good recording. With SoundField
microphones, it is too easy to be lulled into complacency by the excellent stereo and surround
sound pick-up they provide. The temptation is to put it up, turn a few knobs, and go with it.
However, with a little more attention to detail this “good” sound will always become even better.

Be sure to set the appropriate Orientation mode (Side Fire or End Fire ) to tell the DSF-2
processor how the microphone is facing. Then, before ever opening the mic up to stereo, it is
important to listen to the microphone as a monophonic pick-up. Set the Pattern control to Omni
and the Width control to 0° and listen to the overall sound. Pay particular attention to the balance
within the sound source - i.e. the balance among the performers, the relationship of direct-to­reverberant sound, extraneous noises, etc. If it doesn’t sound right, move the microphone around
until it does. At this point adjust the Pattern control to focus more on the sound source and less on
the surrounding environment by utilising the cardioid and figure-of-eight patterns.

Remember that the essence of SoundField microphones is based on the Mid/Side technique, where
the Mid microphone provides the basic sonic balance. Therefore, once it sounds good in mono, it
always will sound great in stereo; the converse, however, is not necessarily true. Only after you are
satisfied with the mono pick-up, should you open-up the microphone into stereo. Set the Pattern
control to the polar pick-up you think will be a good starting point and adjust the Width control for
your desired stereo image. You can adjust both controls to achieve exactly the right stereo
perspective for your recording. Pay particular attention to the direct-to-reverberant sound.
Remember that too much reverb makes a recording sound “mushy” and vague. The beauty of
SoundField microphone systems is their unequalled clarity and articulation. Don’t waste this by
including too much extraneous sound - unless, of course, that is want you want to do! Also keep
an eye on the level meters to be sure that you are not likely to overload the microphone’s
electronics.

SoundField DSF-2 User Guide

CONTROLS

INPUT SECTION - provides all parameters relating to gain, microphone pick-up

orientation and bargraph metering.

1. Gain

The Relay Switched Gain control adds up to a further 40dB of microphone gain in 3dB steps. A
circular LED display illuminates the selected gain position.

2. Limiter

A switchable fixed threshold soft limiter is provided to eliminate the possibility of ‘digital
overload’ and any resulting distortion. It is recommended that the limiter is engaged at all times,
particularly in wide dynamic range environments such as concert halls or sporting events where
sudden crowd applause can create high sound pressure levels. An amber status LED shows when
the limiter is engaged and a red LED displays limiter activity.

3. End Fire

The End Fire mode should be selected when the microphone is horizontally pointed ( ) at the
sound source as you would with a flashlight. Selecting End Fire maintains the correct three­dimensional perspective in both surround and stereo when the mic is used in the horizontal
position.

If you do not select this mode when the microphone is horizontal it will result in the Front/Back
depth information and the Up/Down height information being reversed. When making B-Format
recordings for later surround or stereo post production with the Surround Zone software or DSF-3
Digital Surround Processor, it is important to document the status of the End Fire switch. This
mode is particularly necessary when the microphone is mounted in a Rycote or on a fishpole and
pointed directly at the sound source.

4. Invert

The INVERT mode maintains the correct three-dimensional perspective in both surround and
stereo when the microphone is suspended upside down above the sound source ( ). Not
selecting this mode with the mic suspended will result in the Left/Right width information and

1 2 3 4 5

SoundField DSF-2 User Guide

Page 10Controls

Up/Down height information being reversed. It is important to document the status of the Invert
switch when making B-Format recordings for later post production.

5. Bargraph Metering

The four bargraph meters are switchable to monitor either the four B-Format signals (W, X, Y and
Z) or the stereo Left/Right and Mid-Side. An amber status LED permanently indicates which
monitor mode has been selected. The bargraphs display levels ranging from -37.5dBfs up to
0dBfs.

MIC ROTATE

1. Rotate

Rotates the microphone’s pick up through a full horizontal 360º and redefines the front centre of
the stereo and surround image. A four character display shows the degree of rotation and whether
the ‘Course’ or ‘Fine’ mode is selected. In the Course mode rotation is in 10º steps and in Fine
mode the rotation is in 1º steps for more precise pin-pointing of sound sources.

When setting up to record surround sound without 5.1 monitoring, the Rotate control can also be
used to monitor the rear surround image. Setting the Rotate to 180º, the Pattern control to cardioid
and the Angle control to 90º will give a representation of Surround Left/Surround Right.

NOTE: Any use of the Rotate control during a live broadcast or recording will be embedded
in the 5.1 audio.

2. Active

Rotate ‘Active’ button switches the control in or out of the signal path. An amber status LED is
permanently illuminated when Rotate is activated.

SoundField DSF-2 User Guide

Page 11Controls

STEREO CONTROL SECTION - the controls in the Stereo Section have no
effect on the four B-Format output signals.

1. Hi Pass

A switchable 50Hz or 100Hz high pass filter is available to attenuate unwanted low frequency
rumble or wind noise. An amber LED indicates 50Hz active and a green LED indicates 100Hz
active.

2. M/S

The Mid/Side control switches the digital AES 3-id stereo outputs from L/R to M/S. When the
Mid/Side button is enabled the stereo outputs will be M/S encoded. The Left output channel
provides the Mid signal and the Right output channel provides the Side signal.

A further analogue stereo output is provided which always remains in standard Left/Right (X/Y)
format. This is particularly useful in broadcast applications for feeding back to the commentator as
opposed to the signals available from the O/B vehicle which have incurred significant delays in
order to be synchronised with the video.

3. Pattern

The Polar Pattern control is continuously variable ranging from Omni through Sub-Cardioid,
Cardioid, Hyper-Cardioid to Figure-of-eight and sets the polar patterns used for the stereo pair.

This control dictates the pattern of both the mono or a stereo pair depending on whether the Angle
control is utilised.

4. Angle

This control varies the stereo image from zero degrees (mono) through 90 degrees (standard stereo
coincident pair) to an extra wide stereo 180 degrees. The effect of the Angle control can be viewed
on the Left/Right bargraph metering.

DIGITAL OUTPUT

Sample Rate

The DSF-2 system will operate at the current broadcast sample rate standard
of 48K and in addition offers 96K and 192K sample rates. A sample rate
selector button enables the user to cycle through the sample rate options and
a green status LED displays the selected sample rate. The unit’s outputs
automatically go into mute during sample rate changes.

Headphone Monitoring

Front panel headphone monitoring is provided with a continuously
variable volume control. The headphone section monitors the
Left/Right stereo output. Connection is via a stereo 1/4 inch jack
socket (TRS) and is for use with headphones having an impedance of
400 ohms or greater.

HEADPHONES

Power LED Display

A blue LED is permanently illuminated when the
DSF-2 is powered up. When the unit is first
turned on the DSF-2 will go through its ‘start-up
routine’ during which time the blue power LED
will flash on and off and the four LED bargraphs
will be in full display. When fully initialised the
blue LED will stop flashing and remain on and
the bargraphs will subside. The unit will then
commence to pass audio.

A PRACTICAL GUIDE FOR USE ON 5.1 OUTSIDE BROADCASTS

by Robert Edwards, VSS Ltd.

Only now have the true benefits of SoundField microphones become apparent to the sound mixers
in the live television community who are now being asked to deliver 5.1 audio and more, to
accompany live High Definition Broadcasts. Many such HDTV Broadcasts are for sporting events
where there is no rehearsal and a limited amount of set-up time.

Where should the microphone go in the stadium? The microphone is simplicity itself to rig and is
very tolerant of positioning. It has been said that as long as the microphone is in the same stadium
as the event, the ambience captured will be very enjoyable! However, there are some basic rules
that should be followed...

The microphone must be placed at least five metres from any individual crowd members, and in
such a position so as not to be physically disturbed. Individual claps or voices that are too close to
the microphone will result in making the rest of the ambience difficult to control. The microphone
must be securely mounted, generally clamped to a stadium structure, protected from the elements
(direct wind and rain) with suitable wind and rumble isolation. Generally, the higher and more
centrally-placed above the main crowd or audience, the better the overall sound experience will be.

Typical Crowd Stand

SoundField Microphone

SoundField DSF-2 User Guide

Page 18A Practical Guide for use on 5.1 Outside Broadcasts

The main wide-shot camera position for any event should be used as the reference position for the
SoundField, although this camera position may sometimes not be placed where the main crowd
reactions occur. If the microphone has good free space around it, then the aural image will be
impressive.

SoundField Microphone position near Main Camera Platform

The microphone itself is housed in a Rycote-type windshield. The body of the microphone lays flat
in the mounting clips with the SoundField badge on the microphone downwards. The multi-pin
connector is mated with the microphone and sealed inside the Rycote basket. The microphone,
inside this windshield is then pointed at the main on-field action. In this position the microphone is
said to be in “End-fire” mode, and the “End-fire” switch on the Control Unit should be selected. If
the microphone is rigged so that the SoundField badge is upward, then the “Invert” switch must be
selected. The multi-pin cable is connected from the microphone to the Control Unit. This outputs
four channels of SoundField “B-Format” signals which are algebraic vectors W, X, Y and Z that
are derived from the capsules. The Control Unit is where the gain and orientation of the
microphone is adjusted. The SoundField microphone has a small heating element inside the body,
which keeps the capsules warm and dry. It is therefore essential that the microphone is powered-up
well before use when conditions are humid.

The SoundField has a very low noise-floor and can cope with a wide dynamic range. This is good,
since the crowd reactions of sporting events also tend to have a wide dynamic range. The gain is
best set while the stadium is performing tests on the PA system for safety announcements, as these
are generally very loud and offer a guide to the high SPL achieved in the stadium.

INTERFACING THE DSF-2 WITH THE DSF-3 DIGITAL SURROUND
PROCESSOR FOR LIVE SURROUND BROADCAST

In this configuration the DSF-2/DSF-3 combination will deliver six discrete channels of digital 5.1
surround sound. It is a very quick and effective way to record surround. After some practice and
once you know how to get the best from your system, it will yield consistent results. Although not
vital, it is a big advantage to be able to monitor in full surround when choosing your mic position.
If monitoring in full surround is not possible during set-up, engaging the Rotate control at 180º
with the Pattern control set to Cardioid and the Angle control set to 90º will provide a
representation of the rear sound field (Surround Left, Surround Right).

NOTE: Any use of the DSF-2’s Rotate control during a live broadcast or recording will be
embedded in the 5.1 audio.

If post-production capability is required at a later date for the audio material it is essential to record
the four B-Format signals. A live stereo feed is provided by the DSF-2 or the DSF-3 will provide a
stereo feed in post-production.
