If you are using a subwoofer: When set to `Small' all the system bass will go into the subwoofer. If you choose `Large' the Front channel bass will be reproduced from the Front speakers. Once the loudspeaker settings have been finalised, put the AV amplifier into its "Test" mode (see instructions supplied with your processor). Adjust the level of each channel until all channels are reproduced at equal loudness. You may need to adjust the subwoofer output level. Avoid setting too high a level or you will swamp the sound with bass and may limit the subwoofer's ability to respond to large bass transients. You should also set a sensible level going into the subwoofer from the AV processor. Page117 Fine Tuning Procedures Setting up of the subwoofer should be performed with all tone controls and filters on your amplifier or processor set `flat'. Crossover Networks Castle loudspeakers use a variety of terminal panels. These fall into three types. Biwireable Crossovers A bi-wiring panel has four terminal binding posts. The upper terminals connect to the treble units, the lower pair to the bass unit. As supplied the treble and bass terminal pairs are connected via removeable straps. This arrangement facilitates standard single wiring, and advanced bi-wiring which offers significant performance advantages. Follow the drawings carefully to see the correct orientation of the loudspeaker terminals. Listening rooms are not ideal. Because of room geometry and construction there will be areas with severe peaks at some frequencies and severe troughs at others. If you site loudspeakers in such areas the response will be highly non-linear. It is easier to treat high frequency irregularities by the use of drapes, soft furnishings etc. , but very hard to do the same at bass frequencies due to the very long wavelengths. Castle Classic Range except Howard and Oriel C LASSIC S ERIES 1 Page 16 C LASSIC S ERIES To help locate standing waves in your listening room, one idea is to sit in the listening seat and recruit a friend with a deep voice to speak as he moves around the area where you propose to site your subwoofer - you will soon find out where not to site it!Where the voice sounds most natural is a good place to start. Although the subwoofer's bass output is enhanced by walls or corners, so often is coloration. The surface under the subwoofer should be stable and unobstructed. If the carpet is very thick, consider placing the subwoofer on a solid surface such as a marble slab. If you place the subwoofer where it amplifies the irregularities of the room or the main speakers the result will be bloated, coloured bass. If acoustic guitar and male voice sounds coloured when the subwoofer is operating at normal level and less coloured if the subwoofer volume is reduced, you need to address the positioning first before adjusting any controls. [. . . ] You will need to use low profile cable -your dealer will recommend a suitable product. Lift the loudspeaker up to the mounting position. Align the keyhole slots over the screw headers and gently pull down until the speaker is securely fastened. You may now connect the loudspeaker to the amplifier. [. . . ]
