naimOWNERS MANUALSNAXO 362BMR, 362 & 242ENGLISH DEUTSCHntroductionNaim Audio products are conceived with performance as the top priority. Careful installation will help ensure that their full potential is achieved. This manual covers the SNAXO active crossovers. It begins with some general installation notes. Product specific information begins in Section 3.ConnectionsIt is important for both safety and performance that any standard cables supplied with Naim Audio products are not modified.1.1 Interconnect Cablesterritories allow very high levels of radio frequency radiation and both the choice and exact siting of equipment may be critical. Susceptibility to radio frequency interference is related to the wide internal bandwidth necessary for high sound quality. A radio frequency filter kit is available for some Naim equipment but sound quality will be progressively compromised as mor© elements of the kit ar© fitted.Interconnect plugs and sockets should be kept clean and free from corrosion. The easiest way to clean them is to switch off the equipment, pull the plugs out of tbeir sockets, and push them back in again. Contact cleaners and enhancers* should not be used as the film they deposit may degrade the sound.5 Lightning PrecautionsYour Naim hi-fi system can be damaged by lightning and should be turned off and disconnected from the mains when there is risk of lightning strike.6 Problems?General InstallationNaim equipment is designed to offer the finest performance possible avoiding compromise wherever practical. This can lead to circumstances that may be unfamiliar. The notes that follow contain advice specifically related to Naim equipment as well as more general warnings about the use of domestic audio products. Please read them carefully.2.1 Siting The EquipmentIn order to reduce the risk of hum audible from the loudspeakers, power supplies and power amplifiers should be located a reasonable distance away from other equipment. The maximum separation distance for connected equipment is that allowed by th© standard interconnect lead.2.2 Switching OnSource components and power supplies should be switched on before power amplifiers. Always switch amplifiers off and wait a minute before connecting or disconnecting any leads. Always use the power switch on the product rather than a mains outlet switch.2.3 Running InNaim equipment takes a considerable time to run in before it performs at its best. The duration varies, but under some conditions the sound may continue to improve for over a month. Better and more consistent performance will be achieved if the system is left switched on for long periods. It is worth remembering however that equipment left connected to the mains can be damaged by lightning.Consumer protection varies from country to country. In most territories a retailer must be prepared to take back any equipment he has sold if it cannot be mad© to work satisfactorily. A problem may be due to a fault in the system or its installation so it is essential to make full use of your dealer's diagnostic skills. Please contact your local distributor, or Naim Audio directly, if any difficulties cannot be resolved.Some Naim equipment is made in special versions for different territories and this makes it impracticable to arrange international guarantees. Please establish the local guarantee arrangements with your retailer. Contact Naim Audio directly for help and advice if necessary.2.7 Service and UpdatesIt is essential that repairs and updates ar© only carried out by an authorised Naim retailer or at th© factory by Naim itself. Many components are custom made, tested or matched and appropriate replacements are often unobtainable from other sources.Direct contact to Naim for service or update information should b© made initially through Customer Services:Tel:*44(0)1722 426600Email: infoPlease quote the product serial number (found on its rear panel) in all correspondence.4 Radio InterferenceIn some circumstances, depending on where you live and the earthing arrangements in your home, you may experience radio frequency interference.

They should bo mounted horizontally on an equipment stand intended for the purpose. It is important to ensure that tho stand is level.SNAXO active crossovers contain no internal power supply and must be connected to a dedicated Naim FlatCap, Hi-Cap or Supercap power supply.The SNAXO 362BMR incorporates a suspension system to isdato its sensitive components from vibrational energy. Th© suspension system is protected during shipping by two transit screws. The transit screws must be removed before use. Once th© transit screws are removed the SNAXO must not be inverted. Transit screw removal is best carried out once the SNAXO is installed in its final location and before connections are made.3.1 SNAXO 362BMR Transit ScrewsConnect!Two transit screws must bo removed from the underside of th© SNAXO 362BMR before use and replaced if it is to be carried any distance, packed or shipped. Transit screw removal is illustrated in Diagram 3.2. SNAXO 362BMR transit screws must not be used with any other Naim product.Damage may result if th© SNAXO 362BMR is inverted either during or after transit screw removal.To gain access to the transit screws, position one end of the SNAXO 362BMR over the edge of a table, remove (or replace) the screw that becomes accessible and then repeat with the other end.Transit Screw Removal3.3.1 Power SupplySNAXO active crossovers must be connected to a dedicated Supercap, Hi-Cap or Flatcap power supply.Connect the SNAXO to th© dedicated power supply using, in the case of a Hi-Cap or Flatcap, a Naim SNAIC interconnect cable, and in the case of a Supercap, th© appropriate Burndy cable. In either case take care to connect with th© correct cable orientation.Note: If the SNAXO Burndy power supply socket is not used, the supplied Burndy link plug must be inserted. Similarly, if the SNAXO DIN power supply socket is not used the supplied dust cover should be fitted.3.3.2 Signal InputTo ensure the appropriate signal earthing arrangements, the input signal to a SNAXO active crossover is delivered via its power supply. Th© diagrams on the following pages illustrate signal input connections.3.3.3 Signal OutputsSNAXO output signals ar© carried on 4-PIN DIN sockets. The four or six output sockets should be connected to the power amplifier input sockets as appropriate.Each left and right filter output is available on two separate DIN sockets to enable the use of both mono and stereo power amplifiers.Take care to ensure that SNAXO outputs and amplifier inputs are correct with respect to loudspeaker drive units. Incorrect connection may result in loudspeaker damage.Th© diagrams on the following pages illustrate signal output connections.3.4 Output Level AdjustmentFilter output level adjustment is available via trim controls within each SNAXO. When shipped the trim controls are set nominally flat. Contact your retailer or local distributor for information and advice on level adjustment.SNAXO Connection Sockets4 SNAXO Connection Sockets4.1 SNAXO 362BMR Rear (Ovator S-800, S-600 and S-400)LF2Lower bass drive*unitBMRBalanced Mode Radiator4.2 SNAXO 362 RearHFHigh-frequency drive-unit4.3 SNAXO 242 RearHFHigh-frequency drive-unitSNAXO Power Supply Connections5 SNAXO Power Supply Connections5.1 SNAXO 242 connected to Flatcap XS5.2 SNAXO 362 connected to Hi-Cap240° 5 to 5 pin DINInterconnect CablesMR connected to SupercapSNAXO Amplifier Connections6 SNAXO Amplifier Connections6.1 SNAXO 242 connected to 2 x NAP2505SNAXO Amplifier Connectionsonnected to 3 x NAP250
