[. . . ] U S E R G U I D E KRK V SERIES 2 BI-AMPLIFIED STUDIO MONITOR KRK SYSTEMS LLC. HTTP://WWW. KRKSYS. COM LITK00015 Contents IMPORTANT SAFETY INSTRUCTIONS CAUTION ATTENTION: RISK OF ELECTRIC SHOCK DO NOT OPEN RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated ìdangerous voltageî within the productí s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] Defeatable Limiter - Your V Series 2 monitor contains a transparentl limiter circuit designed to mitigate the negative effects of over driving the amplifier or the speaker. The limiter, when engaged, can greatly reduce the risk of harming a driver. It can however be defeated using the "Clip Off/Limiter Switch" on the rear panel. This is only recommended if you are using the product well within a listenable volume range. NEUTRIK® COMBO CONNECTOR (B) HF ADJUSTMENT (V-8II ONLY) High Frequency Adjustment is through a rear panel mounted 3-position toggle switch. Factory setting for your V8 is flat (toggle switch is in middle position). Room acoustics may dictate which type of adjustment you need to make to retain a flat frequency response from the monitor. (B) LF ADJUSTMENT (V-8II ONLY) Low Frequency turnover is set to 45Hz, 50Hz, or 65Hz by a rear panel mounted 3position toggle switch. Rear panel response curve graphics assist you in selecting the appropriate setting. Factory setting for your V8 is -3dB @ 45 Hz (toggle switch is in up position). Room acoustics may dictate which type of adjustment you need to make to retain a flat frequency response from the monitor. (See additional information in Installing Your Monitors section on page 4. ) 4 The Neutrik® Combo connector accommodates _" phone plugs, XLR, TRS. If you are using an unbalanced connection make sure and wire PIN 1 and PIN 3 together at the source end. 5 Installing Your Monitors The close-field monitor, by definition, reduces room interaction. This can be compared to the conventional stereo configuration or the large monitor arrangement in a recording studio where sounds emanating from the monitor or reflecting off ceilings, walls, and floors greatly affect the sound quality. By shortening the path to the ear, the close-field monitor offers a tremendous amount of flexibility, allowing the sound to become less susceptible to differing room conditions. The ability to adjust the high and low frequency characteristics is equally important to help compensate for room irregularities and achieve the highest sound accuracy. Note- These adjustments are only available on the V8 Series II. ) A room that is heavily dampened would typically require a high frequency boost. The low frequency can be adjusted to compensate for the first reflection (bounce) off the woofer, whether it comes from the floor, as in the typical stereo setup, or from the surface of the mixing board (when the monitor is placed atop the meter bridge). Placing the monitor close to a rear wall, sidewall, or a corner will reinforce the low frequencies. Generally speaking, if you move them two to three feet away from walls and corners, you'll hear less low frequency interaction (excluding any interaction with the mixing console). But when ideal positioning isn't practical, low frequency control is the solution. Lets say you have two different studios in your facility; in one room the monitors are close to the wall, in the other they're further away from the wall. Simply adjust the low frequency on each monitor and you'll have the same sound in each room. [. . . ] If there's absolutely no sound whatsoever, it could be that one or more of the drivers (woofer or tweeter or both) is at fault. It's also possible that the prob lem lies some where in the electronics. Carefully cover the tweeter (to block the sound) without touching the diaphragm. If there is not a clear tonal quality or any sound at all then the woofer probably needs to be replaced. [. . . ]
