[. . . ] the result is a similar increase in the Monitor One's acoustic output over conventional 8 ohm monitors. Reliable handling of this additional acoustic output is ensured by the Monitor One's substantial power handling capability. Typical near-field monitors are rated at 50-60 watts maximum whereas the Monitor One carries a 120 watt continuous power rating and has This a rugged speaker system designed for serious professional use. Covered with a non-slip rubber textured laminate for stable mounting, the Monitor Ones come in a mirror image left/right pair for symmetrical horizontal mounting. [. . . ] Still, 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 position, 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. The first path is the direct one, and the second is via a reflection off the mixer main This kind of speaker placement also couples acoustic energy from the speaker's cabinet more readily into the console's chassis. Both conditions should be reduced by placing the speakers on their own stands acoustically detached from, and slightly behind, the console as shown in Figure 2. In this location, the reflective path off the console's control panel is now blocked by the meter bridge. Monitors placed on the console's meter bridge can directly radiate back onto the console control panel causing a strong delayed reflection at the listening position Random Reflections Moving the monitors to a position behind the meter bridge causes the bridge to block the offending reflective path Careful consideration should also be given to the physical spacing between the speakers. Alesis recommends that the distance between the speakers equal the distance between the listener and either speaker. In other words, the listener and the two speakers are at the three corners of a triangle having equal- length sides. Note that both speakers are turned in somewhat, so that the prime listening position is directly out in front of each speaker. More than one engineer are accommodated by a smaller rotation of the cabinets. The speakers and listener should be at the three corners of a triangle having equal length sides This keeps their height profile as low as possible to minimize the recording engineer's visual obstructions. Your Monitor Ones are supplied as a symmetrical left-right pair, and if used this way, should be installed with the soft dome high frequency drivers towards the outsides of the triangle. The high frequency driver should be on the left side of the left monitor and on the right side of the right monitor (see Figure 4 below). Of course, the traditional method of mounting the speakers with the high frequency drivers at the top is perfectly acceptable too. The high frequency driver should be on the left side of the left monitor and on the right side of the right monitor The Monitor Ones are completely covered with a non-slip rubber textured laminate whereas other speakers provide small stick-on pads (or nothing at all) to keep them from slipping around while they are playing. If you need to move the Monitor Ones or adjust their position slightly, lift them off the mounting surface first rather than attempting to slide them. This type of connector can accommodate bare or tinned 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 recommending speaker wire. Our recommendation is simple; use the shortest length of the largest diameter wire you can get. [. . . ] Do not attempt to clean the cabinet with a brush (which may damage the surface) or a sponge (which may leave small crumbs in the texture). Before sending the Monitor Ones in for repair, make sure they are faulty and that the problem isn't being caused by something else in the system. Connect the Monitor Ones to a system that is known to be working properly to check whether the monitors have malfunctioned. Should service become necessary, YOU MUST FIRST CONTACT ALESIS TO OBTAIN A RETURN AUTHORIZATION NUMBER BEFORE RETURNING THE UNIT TO ALESIS OR AN AUTHORIZED ALESIS SERVICE FACILITY. [. . . ]
