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. (See 

HF Adjustments 

and

 LF 

Adjustments

 sections on page 2.)

 

 
A room that is heavily dampened would typically require a high frequency boost. Likewise, reducing the high 
frequencies can alter a reverberant room. 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 V-88’s 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. This comes in handy if you're tracking in room A and mixing down in room B. 

Positioning Your Monitors 

Positioning your monitors correctly in the studio is critical to their performance. Typically, they should be placed so 
that that the listening position is fully "covered" with all monitors resting on the same horizontal plane. A great way 
to test a monitor for its imaging capability is to play back a CD or DVD recorded acoustically in stereo (or one 
recorded in surround sound if you have a surround sound set-up).  We recommend acoustic music because it 
represents the spectrum of sound.) 

 

You can adjust the angle of each monitor by listening for dead spots. Keep in 

mind, changing the angle or position of a monitor will change the sound. 

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. In this configuration, the Left and Right monitors are each placed at a 60º

 

angle equidistant 

from the listening position.
