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. -
Page 7: Product Description
PRODUCT 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”... -
Page 8: Subwoofer Setup
SUBWOOFER SETUP 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. -
Page 9: Aes/Ebu Input
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. - 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.

Page 11: Parameter Definition
3.3 Parameter definition 3.3.1 Subwoofer Volume The subwoofer volume is the first menu item. It can range from -40dB to +20 dB by steps of 0.5 dB. Figure 6: Volume parameter and values 3.3.2 Digital Channel Selection The digital channel selector is the second menu item. It allows the user to select the first channel (A) or second channel (B) of a IEC60958 digital audio stream. -
Page 12: Digital Output Selection
When the selected digital input does not receive a valid digital audio stream, the separation symbol of the second display line changes its form to an empty square frame instead of a plain square.

Figure 13: Display behavior when the analogue input level exceeds the selected full scale level 3.3.6 Curve selection The Curve selector is the 6 menu item. The user can select a preset curve which will modify the frequency response of the monitor to emulate a given acoustical environment. There are 7 presets plus the FLAT reference. -
Page 14: Eq Set Selection
The curve “TV” simulates the frequency response of a standard TV set. The curve CLUB simulates the listening in a night club environment. A 2 dB boost at 60 Hz and a 5 dB boost at 3 kHz. 3.3.7 EQ Set selection The EQ Set selector is the 7 menu item. -
Page 15: Subwoofer Relative Delay
Figure 16: Relative subwoofer level parameter and values 3.3.9 Subwoofer relative delay The subwoofer relative delay is the 9 menu item. It can range from 0 cm to 150 cm by steps of 5 cm. Speakers relative delay is meant to time align the speakers in a multi- channel system. - Page 16 Figure 20: Tilt 1 gain parameter and possible value 1000 Frequency (Hz) Figure 21: Tilt 1 frequency response for -3dB, -2dB, -1dB, 0dB, +1dB, +2dB and +3 dB gain (Frequency = 35 Hz and Q = 1 are factory default) Figure 22: Tilt 2 gain parameter and possible value 1000 Frequency (Hz)

Page 18: Subwoofer Phase
3.3.13 Subwoofer Phase Figure 28: Cross-over Phase and possible values The absolute phase is the 16 menu item. It defines the phase offset at the cross-over frequency. The phase offset is implemented by an all-pass filter of the second order. The value 0 deg. -
Page 19: Network Mode
3.3.15 Network mode The network mode is the 18 and last menu item. It defines the behavior of the subwoofer on the network. In Slave mode, a change made on the subwoofer parameter via the subwoofer control panel is reflected on the network to allow the remote control or the SCS to keep updated on the speaker system configuration. -
Page 20: Network Operation
3.4 Network Operation The FAR Active Monitors can be connected together via the FAR Link network, using standard CAT5 cables (like the ones used in Ethernet PATCH connections). WARNING: DO NOT USE ETHERNET CROSS CABLE. They will not work properly. The network is optional in the use of the monitors. -
Page 21: System Setup
SYSTEM SETUP In this chapter, the speaker will be represented by a box showing the speaker function with the required speaker parameter values and a box showing, for the same speaker, the digital signal routing. For instance, the following speaker representation is the .LEFT. one in the system. It has its speaker ID configured with the value “1.FRONT LEFT”, its input set to “AES/EBU”, its digital output set to “AES/EBU”... -

used. Once again the network cables are optional if no remote control is required. The sequence in which the speakers are linked with the network cable is not relevant for this application. 4.2 Digital setup 4.2.1 Stereo 2.0 System There are 2 ways to setup a digital 2.0 system. The first one relies on the FAR Link network to carry audio and control between the LEFT and the RIGHT speakers. -
Page 23: Stereo 2.1 System
AES/EBU (LEFT & RIGHT) LEFT RIGHT Note: It is not useful to have both the XLR cables and the network cable in place between two speakers. The quality of the digital audio link provided by the FAR Link network is at least as good as the one of a classical AES/EBU output on XLR connector. 4.2.2 Stereo 2.1 System A subwoofer can be used to improve the bass extension of a stereo system. -
Page 24: Multi-Channel 5.1 System
However, for practical reasons and future system maintenance easiness, we do strongly recommend using the FAR Link network, even if no remote control is required. 4.2.3 Multi-channel 5.1 System A 5.1 digital setup does require 3 AES/EBU cables, each of them carrying 2 audio channels. - Page 25 Note: If a second subwoofer for the LFE channel is required, it can simply be inserted right before or after the first subwoofer. The second subwoofer will copy all the settings of the first subwoofer but the spear ID that shall be “9.SUBWOOFER 2”. If the proper sequence cannot be respected because the main cabling requirement is to have a speaker linked to its closest neighbor in the room, some speakers will not get the appropriate audio channel through the network.

fed to the LEFT speaker, which bridges the stream to the FAR Link network. The LEFT speaker network output is connected to the CENTER speaker network input. But the CENTER speaker also has an AES/EBU (CENTER & LFE) cable connected to its DIGITAL IN connector. - Page 27 …or may decide to keep the network cables as short as possible (as explained in details in the 5.1 setup description). The speaker ID of the surround center can either be set to “6.EXTRA L” or “7.EXTRA R”. Page 27...
