At-g. sits 1996 Intloduction Thank you for purchasing the Alesis Point Seven Shielded Reference Monitors. To take full advantage of the Point seven's operation, and to enjoy long and trouble. ftee use, please read this user's manual carefully. How To Use This Manual This manual is divided into the following sections describing the various features of the Point Sevens. Though we recommend you take time to read through the entire manual once carefrrlly, those having general knowledge about monitors should use the table of contents to reference specific functions. Engineering specifications and redsons why near field monitors have become so popular. [. . . ] You should avoid locating your Point Sevens near reflective surfaces such as glass, tile, large open walls or table tops. Sti[ many rooms used for recording have these surfaces, so the best way to deal with them is to place the monitors out in the room away from reflective walls, windows and sizable objects. Even with these reflective surfaces separated from the monitoring positiory typical mixing situations usually still have the top surface of the mixing board to deal with. Unfortunately, the board itself can be a major source of reflections and the additional acoustic conduction into the board can affect your monitor's amplitude and phase response. Speaker placement on the console's meter bridge provides for two clear acoustic paths between the speakers and the recording engineer which results in undesirable comb filtering effects and poor imaging. If they are used by themselves, without any outside bass augmentation (i. e. a subwoofer), then the ports should be left open. This will give a ". balanced" sound. 3dB bass boost between 90Hz and 130H2 and result in a "accurate" sound and are willing to sacrifice bass If, however, you want the most response below 100H2, then insert the plugs. This will give slightly less apparmtbass but the sound will be tighter and very well damped. When used with a subwoofer, the Point Seven's plugs should always be used. If the ports are left open and a subwoofer is used, the resulting sound will have a bloated, unnatural midbass.

This type of cormector can accommodate bare or tirmed wires, banana plugs and even spade lugs. About Wire: A lot of hype and confusion exists about the type of speaker wires to use, most of it created by the wire manufacturers themselves in an effort to have a unique story to tell. While this expensive wire will not hurt the speaker's performance at all, Alesis does not subscribe to most of this hype and chooses to take an approach based on science when recommmding speaker wire. Our recommendation is sirnple; use the shortest length of the largest diameter wire you can get. #12-14 gauge multi-stranded speaker wire found at most hi-fi and electronics stores works very well. This kind of wire resembles oversized lamp cord and is very easy to work with. Before connecting the speakers, check that your amplifier is tumed OFF. Be sure you get the + terminals of the speakers wired to the + terminals of the amplifier. To help you do this, most speaker cable has a way to tell one conductor from another. Some use different-colored wires or insulation; others mold a small line or marker into one insulator to mark it.
