U S E R G U KRK VXT SERIES BI-AMPLIFIED STUDIO MONITOR I D E
Introduction Congratulations on your KRK purchase! And welcome to the growing family of KRK owners. KRK’s VXT Series of powered studio monitors are precision speakers designed to forever change the way you handle your most demanding audio jobs. VXT means truth in French and that’s just what these monitors are all about - they reveal the truth in your audio material. The VXT monitors feature key design elements that continue to make the KRK sound a “studio standard”.
Design Philosophy A studio monitor is a tool used to aurally “measure” the changes in an audio path. Ask any seasoned recording professional what they think makes a great studio monitor and you’ll get basically the same answers: “Accuracy, transparency, flat response, and the truth.” Simply put, recording engineers want the electrical signal entering their monitor to be reproduced mechanically by the transducers and they want this to occur without any deviation or compromise to the original signal.
Design Elements New Custom Made Tweeter and Woofer Designs – KRK is renowned for designing high performance studio monitor drivers. Your VXT monitors are no exception. A woven Kevlar® low frequency driver was custom-designed specifically for each model. Kevlar® is one of the strongest, lightest, most rigid materials that can be used in modern speaker cone construction. Kevlar’s unique physical properties minimize axial or conical break up modes. Both tweeters and woofer provide faster attack times.
Back Panel Features (A) SYSTEM LEVEL ADJUST Input sensitivity is adjusted (counterclockwise reduces sensitivity) through a rear panel mounted trim control. Adjustment range is from -30dB to +6dB. Factory preset gain is +6dB, which should suffice for most conditions. Normally adjustments would only be made if you’re using your VXT monitors in a surround system and you need to balance levels or if your monitor-source is too hot and not adjustable.
The three-way toggle switch provides the ability to adjust the low frequency when the monitors are effected by by room boundaries such as walls and corner locations. The setting labeled WHOLE refers to the term "Whole Space" and is used to provide the most bass response. QUARTER refers to quarter space and rolls off the most low frequencies. HALF refers to "Half Space" and provides a setting in between no roll off and QUARTER space roll off. Your monitors come from the factory set to WHOLE space.
NEUTRIK® COMBO CONNECTOR The Neutrik® Combo connector accommodates XLR, 1/4” TRS and 1/4” phone plugs. Please note that PIN 2 is hot! If you are using an unbalanced connection make sure to wire Sleeve and Ring together at the source end. This can be accomplished by using the appropriate cable or adapter. Installing Your Monitors The close-field monitor, by definition, reduces room interaction.
2-CHANNEL SET-UP Close-Field Configuration - In a control room situation, the monitors are often times placed on the meter bridge or in a close-field listening position. Initial placement starts by measuring out a simple equilateral triangle (all three sides equal in length) with the apex at the center of the listening position (as shown in Figure 1) as an "overlay" for the stereo installation.
Figure 3 5.1 Channel Surround Sound Setup Begin by placing the Left and Right front channels 30 degrees from the Center channel and equidistant to the listening position (Figure 4). The Left Surround (rear) and Right Surround (rear) channels should be placed 110 degrees from the Center channel. Their location should also be equidistant from the listening position. The subwoofer (Low Frequency Effects) channel is most effective when situated directly below the Center channel (as shown in Figure 4).
7.1 Channel Surround Sound Setup The 7.1 channel surround sound setup adds two speakers to the sides of the mix position and is most similar to the actual surround sound configuration of cinema—with the difference being that cinemas commonly add additional side surrounds to compensate for the length of the theater. The front Left and Right speakers typically form a wider triangulation (in relation to the mix position) than that of a 5.
Troubleshooting Problem: If there is no power, check to see if... • The power cord is plugged into both the IEC socket on the rear panel of the unit and into the AC mains • The AC mains voltage is matched to the operating voltage requirements (See Changing Voltage in the Connecting the System section on page 3). If the AC mains voltage is higher than your monitor’s selected voltage it is possible that the fuse needs to be replaced. (See Changing Fuses in the Connecting the System section on page 3).
Problem: The sound quality changes... • Repeat steps in the previous troubleshooting section above before continuing to the next steps. • Disconnect the signal cable at the input of the monitor. With power on, place your ear close to each driver (tweeter/woofer) and listen for noise (i.e., a slight hiss or hum). 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.
