User manual CASTLE HARLECH

[. . . ] There are no user serviceable parts inside and you will invalidate the warranty. You should site all Castle Knights loudspeakers at least 0. 5 m away from TV sets and magnetic storage media. All Castle centre loudspeakers may be sited close to a TV screen with no adverse effects. When connecting your loudspeakers, do not run cable across areas of open floor where they may be a source of danger. [. . . ] If you are unpacking the larger loudspeakers remember that these units are heavy. Unpack any accessories carefully. K NIGHTS S ERIES If there is any sign of damage or if the contents are incomplete, report this to your dealer as soon as possible. If you dispose of the packing, do so with respect to any recycling provisions in your area. Stand mounting loudspeakers are ready to be connected after unpacking. The larger loudspeakers will need to be assembled on their plinths and spike kits. Attaching the Plinth and Spikes to Floorstanding Models # # # # # # # # Ensure you have plenty of unobstructed working space. Insert the screws into the threaded holes on the loudspeaker and tighten securely. Be careful not to damage the floor with the spikes. Knob Spike Locknut Spacers # Levelling the Loudspeakers When the speaker is upright: # You will probably find that the speaker will wobble with one spike not contacting the floor. With the aid of a spirit level move each spike in and out until the loudspeaker is level and sitting squarely on all four spikes with no rocking. Now tighten each locknut securely against the collar in the plinth to secure the spike. and should be placed as shown. Knob # # # Locknut Spike Using the Spike Seat Important notes on floorstanding loudspeakers: # # The plinth is an integral part of the design. Follow the drawings carefully to see the correct orientation of the loudspeaker terminals. K NIGHTS S ERIES Why Bi-Wire? Bi-wiring involves the use of two separate cables between the amplifier and the loudspeakers. Using separate cables for treble and bass units in a Bi-Wiring configuration reduces intermodulation effects and improves headroom and clarity. To biwire, you will need to install two lengths of twin core cable between the amplifier and each loudspeaker. As supplied Bi-amplifying The bi-wiring principle can be further extended by bi-amplifying (bi-amping). One amplifier is connected to the treble terminals and the other to the bass terminals of the crossover panel. Because each amplifier is working over a narrow range, intermodulation distortion is virtually eliminated and acoustic performance optimised. The amplifiers in the treble and bass sections of a bi-amped loudspeaker need not be identical but they must exhibit the same phase characteristics. If you wish to bi-amp your loudspeakers we suggest you consult your Castle dealer if you are in any doubt. In bi-wiring mode 1 Page 5 Positioning Stereo Loudspeakers The distance between the speakers should be the same as between you and the speakers. K NIGHTS S ERIES 1 Page 6 If the loudspeakers are placed too close to the walls, the bass will increase but may be boomy and indistinct. If the loudspeakers are placed further away from the walls, the inward angle ("toe in") may be increased by up to 30% As personal taste plays a large role, experiment with different configurations and play a wide range of programme material before finalising the position of your speakers. The optimum listening position is in the area broadly known as the `sweet spot'. Castle loudspeakers are designed to cover a medium sonic perspective so there should be no need fo extreme settings. 2-4 metres 700mm 15° 0° 3 Floorstanding: >200mm Stand mounted: >100mm Listening Sweet Spot Stand Mounting Loudspeakers The Knight 1 and Knight 2 are designed for stand mounting. [. . . ] The stands should be sturdy and offer optimum support for the loudspeaker. As an alternative the speakers may be wall mounted on rigid brackets or placed on rigid shelves. If the rear panels of the speakers are placed close to the walls, the amount of bass will be increased but the clarity may well suffer - you should experiment until you get the best result. Connecting Your Loudspeakers Standard Loudspeaker Wiring Choose a suitable length of twin core speaker cable for each channel, and prepare the ends. Connect the red, positive (+) terminal of the Left loudspeaker to the corresponding red, positive (+) amplifier terminal. [. . . ]
