Whether you are making critical mixing decisions or need to capture the subtle nuances of a unique sound, you’ll quickly discover that the VXT Series is as precise about your work as you are.
2. Distortion Management Any loss or addition to the audio signal is a distortion and this can occur in the speakers themselves. The VXT series has very low speaker distortion which, of course translates into improved reproduction accuracy. Various amplifier distortions have been eliminated as well; the most common being intermodulation, transient intermodulation, and harmonic distortion.
These characteristics aid in eliminating the cabinet from potentially coloring the sound of the speaker system. Active Filter Crossovers - The VXT series power amplifiers contains three active filters. (Subsonic, low-pass and high-pass filter) These three filters work together to provide a seamless integration of the driver components ensuring a smooth spectral balance.

Back Panel Features 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.
Lift/GND Switch Engaging the ground lift switch can sometimes reduce ground loop noise in your system. By providing an AC mains ground on the VXT and proper installation in a 'quiet studio' environment, the system is happily quiet. However, noise will be induced if the monitor is installed in less than desirable settings (i.e. audio cables run alongside power cables, behind refrigerators, near florescent lighting, older buildings with bad wiring), or with certain equipment with lots of RFI (lap-top supplies, PCs, generator supplied AC lines).
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.

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"...

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.

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.

Monitor suddenly stops working. • Turn the monitor level down or off • Repeat steps in the troubleshooting sections above before continuing to the next steps. • Carefully check to see if the amplifier's back plate is hot! If the monitor has been running at highest power output for an extended period of time, it could be that the unit has become overheated and the protection circuitry has shut the system down momentarily.
