1 INTRODUCTION
1.1 This Manual
The latest manual revision is always available for download from www.atd2.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 AV series include high
quality analogue amplification with the addition of powerful DSPs and CPU. New
possibilities are opened for easy, convenient and central control of both audio and setupinfo 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 AV monitors are Pro Audio near-field / mid-field monitors and are excellent for stereo
and surround setups in applications such as Music Recording/Mixing, Post production,
Film, Broadcast, Video-editing etc.
Unlike many rear-ported monitors that can be very unpractical to set up, the 2 ways AV
monitors feature a front-ported bass reflex that allows flush mounting and easy
placement in the room.
1.3 Digital Precision
The frequency response and timing of the woofer, medium and tweeter signals (gain and
delay) of the AV monitors is controlled to a level of precision only practically obtainable
with DSP.
All the filters available in the speaker are implemented in the digital domain. This
guarantees a perfect repeatability from speaker to speaker. They will never vary with
temperature, humidity and aging. It cannot be made more accurate and stable.
The monitor impulse response has been optimized to guarantee the best possible
dynamics and accuracy.
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.

2 PRODUCT DESCRIPTION
The AV monitors are multi-amplified (2 amplifiers in total). There is one amplifier per
driver unit. Refer to chapter 5 [Technical Specifications] for details.
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 speakers
were designed to be “clicks and plops” free, in any conditions.
The following figure describes the speaker 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 speaker is powered ON and that also
signals with various types of blinking the network activity, amplifier limiter in service and
hardware faults.

3.1 Connectivity
The speaker 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, +21 dBu and +24 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 – 24 bits). It is then treated as the other digital audio streams that can be fed to
the monitor.

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. 2 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. 2 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 speaker 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 2 lines. The first line shows the
selected parameter and its value. The second line gives the speaker 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
