1INTRODUCTION
1.1 This Manual
The latest manual revision is always available for download from www.atd .com. Please
compare to the revision number of the manual (see page 4) available for download from
our web-site and download if newer. The present document will describe how to connect
and setup a speaker system.
1.2 The Product Concept
The FAR Active monitor systems take a quantum leap forward in near-field / mid-field
monitoring and ATD2 is very proud to present these systems. The SUB15.D includes
high quality analogue Class D amplification with the addition of powerful DSPs and CPU.
New possibilities are opened for easy, convenient and central control of both audio and
setup-info via dedicated PC software and remote control. The networking possibilities
will fit nicely into today's applications and can be taken far into the future studio.
The SUB15.D is a Pro Audio near-field / mid-field subwoofer and is excellent for stereo
and surround setups in applications such as Music Recording/Mixing, Post production,
Film, Broadcast, Video-editing etc.
Unlike many rear or front-ported subwoofer that can be very unpractical to set up, the
SUB15.D feature sealed box bass principle design that allows flush mounting, easy
placement in the room and very accurate bass reproduction.
1.3 Digital Precision
The frequency response of the subwoofer of the subwoofer is controlled to a level of
precision only practically obtainable with DSP.
All the filters available in the subwoofer are implemented in the digital domain. This
guarantees a perfect repeatability from subwoofer to subwoofer. They will never vary
with temperature, humidity and aging. It cannot be made more accurate and stable.
As most productions do end up in a digital format these days, the FAR Active monitors
allow direct monitoring of the digital signal. Simply feed the monitors directly with an
AES/EBU signal (IEC60958 compliant).
However, as many studios are today still working with analogue signals for monitoring,
all the FAR Active monitors have, as standard feature, a very high quality analogue input.

2PRODUCT DESCRIPTION
The subwoofer box is sealed (infinite baffle principle of work). There are no venting
ports. This brings the following advantages:
-Flush mounting is possible (no rear port)
-No sensitivity to placement with respect to the rear wall (no rear port)
-No “out of phase” interferences between the woofer and a front port
-Cleaner and more accurate restitution in the bass frequencies
There is no such a concept of Master and Slave monitors. All FAR Active monitors have
the same capabilities and features. There are also no special requirements on power ON
and OFF sequences of the monitors. The subwoofers were designed to be “clicks and
plops” free, in any conditions.
The following figure describes the subwoofer synoptic.

All controls, display and connectors are located at the rear of the monitor with the
exception of a front LED that indicates when the subwoofer is powered ON and that also
signal with various types of blinking the network activity, amplifier limiter in service and
hardware faults.

3.1 Connectivity
The subwoofer provides the following connectors:
-XLR Analogue balanced input
-RJ45 FAR Link Network input
-RJ45 FAR Link Network output
-XLR AES/EBU digital input
-XLR AES/EBU digital output
The power input is an IEC connector.
3.1.1 Analogue Input
The monitor has a balanced analogue input on a XLR combo plug. The full scale
sensitivity of the analogue input is selectable via the monitor control menu. It can be set
to +3 dBu, +9 dBu, +15 dBu, + 1 dBu and + 4 dBu.
The standard broadcast full scale input level is +6 dBu with 9 dB headroom. In this case,
the full scale input shall be set to +15 dBu.
The analogue signal is converted to the digital domain by a very high-end converter
(96kHz – 4 bits). It is then treated as the other digital audio streams that can be fed to
the monitor.

Page 9
3.1.2 AES/EBU Input
The monitor has a balanced AES/EBU input on a XLR combo plug. The AES/EBU input is
selectable via the monitor control menu. The AES/EBU input complies with the IEC
60958 standard. audio channels are carried over an IEC60958 stream. The desired
channel is selectable via the monitor control menu.
3.1.3 AES/EBU Output
The monitor has a balanced AES/EBU output on a XLR plug. The AES/EBU output content
is selectable via the monitor control menu. The AES/EBU output complies with the IEC
60958 standard.
The typical use of the AES/EBU output is a signal loop-through to feed other monitors
with the same signal.
3.1.4 FAR Link Network
The FAR Link network allows for streaming of monitor control messages and a pair of
digital audio channels compliant with IEC60958 (AES/EBU like but on another medium).
3.1.4.1 Control Channel
The control channel allows the exchange of messages and data between the monitors
and/or the remote control devices (PC or dedicated remote control).
3.1.4.2 Digital audio input
The monitor can use a CAT5 cable on RJ45 FAR Link TM network plug to receive a digital
audio stream compliant with IEC60958. The Network digital audio input is selectable via
the monitor control menu. audio channels are carried over IEC60958. The desired
channel is selectable via the monitor control menu.
The Network digital audio stream and the AES/EBU stream can run concurrently, making
4 digital audio channels simultaneously available to each monitor.
3.1.4.3 Digital audio output
The monitor can use a CTA5 cable on the RJ45 FAR Link TM network plug to transmit a
digital audio stream compliant with IEC60958. The Network digital audio output content
is selectable via the monitor control menu.
3.2 Operation Overview
The control panel at the subwoofer rear gives access to the basic configuration
parameters of the monitor. The menu items can be selected (displayed on the
alphanumerical screen) using the left and right keys (PREVIOUS / NEXT) while the
parameter value is changed using the up and down keys (+ / -).
The alphanumerical LCD displays the information on lines. The first line shows the
selected parameter and its value. The second line gives the subwoofer status.
Figure 4: Display layout
The input signal field indicates the signal currently used by the monitor. When the
central button is pushed, the monitor is muted and the field shows “Mut”. In nominal
operation, the field can get the following values:
-ANA to indicate that the analogue input is active
-AES to indicate that the AES/EBU input is selected

Page 10
-NET to indicate that the FAR Link network is the signal source
The following picture shows the various subwoofer parameters accessible via the control
panel and their associated value range.
