AV Products Introduction Welcome. In selecting ATC you have chosen an ATC has become synonymous with active systems. Choosing to offer active example of the finest audio engineering loudspeakers (where the passive crossover network is replaced by active filters and available. ATC was founded on a principle of multiple power amplifiers) is simply a result of the uncompromising attitude to engineering excellence, and that principle still loudspeaker design.
Centre Speaker Installation C4/C5/C6/C7 Active 1.1 Centre Speaker Placement The positioning constraints on a centre channel loudspeaker are always influenced by the type and location and of the associated screen. However, the basic parameters that influence the subjective performance of any loudspeaker in a listening room alignment to the listening position and proximity of room boundaries - also apply to a centre channel and should be taken into account.
C4/C5/C6/C7 Active Centre Speakers Installation 1.3 Signal Cable Options 1.4 Operation Balanced cable configuration is the preferred The C4, C5, C6 and C7 are connected to the mains and signal cables via sockets on option, however unbalanced connection is possible. the rear panel. The rear panel also carries the mains switch and fuse holder. Each Diagrams 2 and 3 illustrate the signal cable feature is described below. connections required for each option.

C1 Active Sub-woofer Installation 3.1 Sub-woofer Placement 3.2 Connection The subjective performance of any sub-woofer will Mains power and signal connections are required for the C1 Sub-woofer. The mains be fundamentally influenced by the acoustic cable is specifically supplied to comply with local statutory safety approvals and character of the room in which it is used, and its alternatives should not be substituted. If you intend to use your sub-woofer in an position within the room.
C1 Active Sub-woofer Installation 3.3 Operation The C1 sub-woofer control and connection panel provides a range of adjustment facilities to assist its integration with the satellite speakers. These facilities are explained below and illustrated in Diagrams 2, 3 and 4. Level: Sets the overall sensitivity of the sub-woofer.
C1 Active Specifications C1 Active Sub-woofer 3.4 L i s t e n i n g c o n t ’d sufficient sound pressure levels for your ears themselves to become a source of distortion and make the sound appear harsh. Any audible distortion indicates that either the system or your ears are being overloaded and that the volume level should be reduced. 3.5 Care and Maintenance High technology material finishes are used in this product.
C2/C4/C6/C7 Active Sub-woofer Installation 4.1 Sub-woofer Placement The subjective performance of any sub-woofer will be fundamentally influenced by the acoustic character of the room in which it is used, and its position within the room. Monitor and sub-woofer systems are most often installed in rooms which are comfortable to sit and talk in, and the typical mixture of carpets, curtains and soft furnishings help ensure that middle and high frequencies are reasonably well controlled.
C2/C4/C6/C7 Active 4.4 Sub-woofer Installation Operation The sub-woofer amplifier control and connection panel provides a range of adjustment facilities to assist its integration with the satellite speakers.These facilities are explained below and illustrated in Diagrams 4, 5 and 6. Level: Sets the overall sensitivity of the sub-woofer. Initially the level control should be set towards the centre of its range and only adjusted once the Low Pass and Contour controls have been set.

System Installation S p e a ke r Po s i t i o n i n g 5.1 Full Bandwidth S p e a k e r Po s i t i o n i n g While each loudspeaker in an AV system should be located appropriately in its immediate acoustic environment (see the positioning section in each loudspeaker User Guide), if an AV system is to reach its full potential the relative position of each loudspeaker element must be considered.
System Installation Bass Management 5.2 Bass Management in Domestic Systems • High quality systems have enough dynamic range and bass extension without the use of This section aims to clarify some of the issues surrounding the use of Bass Bass Management. Less software processing of Management (or bass redirection as it sometimes known) in ATC multichannel the source material implies less potential for systems.
