Design Philosophy
Design Elements
A studio monitor is really a tool used to aurally “measure” the changes in an audio
path. Ask any pro or semi-pro recordist what they think makes a great studio monitor and you’ll get basically the same answers: “Accuracy, transparency, flat
response, and the truth”.
Active Filter Crossovers - The V-Series 2 power amplifier 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.
Everybody is saying the same thing – they want the electrical signal going in to a
monitor to be reproduced mechanically by the transducers and they want that to
happen without any degradation to the original signal. Professionals need to trust a
speaker to deliver their artistic vision in a way that will translate to a variety of audio
mediums. How you get there from a technical stand point is by designing a speaker
that eliminates or minimizes several damaging conditions. The KRK design philosophy is manifested by paying very close attention to what we call the three cornerstones:
Bi-amplifier Design– KRK’s amplifier consists of audiophile grade components
and a simple audio path for transparency. Output power is balanced to match LF
and HF driver sensitivities and power handling. Your V Series 2 monitor uses a
toroidal power transformer for low hum and minimum noise.
1. Spectral Balance (Timbre)
Radiused Edges - All cabinet edges and port openings are heavily radiused to
reduce diffraction resulting in better detail and stereo imaging.
What people tend to think sounds good is not necessarily “flat response”. A perfectly flat monitor tends to sound harsh and abrasive – technically correct but not very
musical. Research shows us that a speaker with the proper spectral balance is
most often considered “a great studio monitor”.
Spectral balance is defined by:
• Smooth on-axis (not necessarily flat) response
• Smooth octave to octave response
• Smooth off-axis response (not necessarily flat)
From years of listening to feedback from some of the top engineers and producers
we’ve come to understand how a properly tuned monitor can become a valuable
recording tool.
2. Distortion Management
Any loss or addition to the audio signal is a distortion. Various amplifier distortions
have been eliminated; the most common being intermodulation, transient intermodulation and harmonic distortion.
Distortion can be present in an amplifier circuit but can really be a problem when
the waveform is impacted by physical conditions such as port turbulence and diffraction. KRK engineers implement design concepts that eliminate or minimize
these damaging conditions.
Resonant Free Enclosure Design - The cabinetry of your V Series 2 monitor is
constructed from inert medium density fiberboard. It is internally braced and carefully damped to minimize cabinet resonance.
Slotted Ports – Slotted ports reduce the port turbulence and distortion commonly
found in poorly designed round ports.
Custom Made Drivers - KRK is renowned for designing high performance studio
monitor drivers. Your V Series 2 is no exception. A woven Kevlar® LF 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. A
1inch soft dome tweeter was designed for detailed and accurate high frequency
reproduction. Ferrofluid is used for increased thermal power handling and
increased damping.
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. Use the indicators on the front baffle to help determine the optimum level
without audible distortion
3. Resonance Management
Resonance is the tendency of something to vibrate at a particular frequency after
the source of energy is removed.
Resonances also play a major role in impacting the performance of a speaker. KRK
design elements minimize driver and enclosure resonance.

Back Panel Features
A
(A) SYSTEM GAIN
C
B
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 Series 2
monitors in a surround system and you
need to balance levels or if your monitor-send is too hot and not adjustable. If
an adjustment is necessary, you’ll need
a small flathead screwdriver and some
measuring equipment. (E.g. tone or filtered noise generator and SPL meter)
(B) HF ADJUSTMENT (V-8II ONLY)
High Frequency Adjustment is through a rear panel mounted 3-position toggle
switch. Range of control is +1dB, Flat, or -1dB shelving above 1 kHz. 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.
(C) Clip Indicator/Limiter Switch
The Clip Indicator/Limiter switch allows you to choose between 3 options.
1. In the On position the clip led is active. The LED will gently flash red at the earliest sign of distortion and growing brighter with the increasing level of distortion.
2. In the “Off” position the clip LED is inactive. This may be desirable if the led is a
distraction.
3. In the “Limit” position the signal is routed through the Limiter circuit and the signal is limited when a predetermined threshold is passed. This can be monitored
with the Green LED on the front baffle. The more limiting the more the green light
stays on .
Connecting Your System
POWERING ON
All connections should be made, all faders and controls
should be set at their minimum levels, and all other equipment should be powered on prior to powering on your V8
monitors.
The power On/Off switch is located on the rear panel and
is internationally marked to indicate the operational status.
( — ) = ON and ( O ) = OFF. A yellow LED illuminates the
trademarked KRK Triangle on the front baffle when power
is applied.
Auto On/OFF Switch
The Auto On/Off feature allows you to either choose between manually powering
up the speaker or selecting the Automatic On feature. The Auto circuit detects a
signal, turns the power on allowing it to pass a signal and shuts the power off after
20 minutes of silence.
NEUTRIK® COMBO CONNECTOR
(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.)

make sure and wire PIN 1 and PIN 3 together at
the source end.

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. Note- These adjustments are only available on the V8
Series II.)
Mid-Field Configuration – This configuration is basically the same as the CloseField set-up. (see Figure 2) It is normally used with larger monitors or when the
monitors are too large or heavy for the meter bridge. This set-up has the potential
for a larger sweet spot and better spatial imaging. Make sure that the height of the
woofer is above height of the console.
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 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. 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.
Figure 2
SUBWOOFER SET-UP
Begin by determining the best location for your subwoofer. If possible, the optimum
set-up would look like the set-up in Figure 3. This set-up may not be practical or
possible in your room. Once you have set up your monitors. Listen to some program material that you know has low frequency information recorded on it.
Different locations may create a phase misalignment. Most Subwoofers have a
phase switch on them. Flip the phase switch. The bass response volume will
either increase or decrease in volume. Whichever setting gives you the loudest
response from your seating position is in phase. After you have the proper phase
setting you will need to adjust the output level of the Subwoofer to a level that provides a smooth blend of the bass volume with that of your monitors.
Figure 3
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.

5.1 CHANNEL SURROUND SET-UP
Troubleshooting
Begin set-up by placing the Left and Right front channels 30º 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 110º
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).
If this is not possible place the subwoofer just to the right or left side and below the
Center channel. Make sure that the woofers are above the height of the
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 the V-8’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).
• The power light is illuminated on the front panel of the V8. If not, turn the power
switch OFF and check the A/C mains fuse(s). NEVER USE A LARGER AMPER
AGE FUSE THAN IS SPECIFIED! Turn the power switch back on. The power
light should illuminate.
• If a fuse change was needed and upon powering the monitor back up the fuse(s)
blow again, the monitor needs to be returned to the dealer you purchased it from
or to KRK for servicing.
Figure 4
console.Once the monitors have been placed, you need to adjust the SYSTEM
GAIN pots (see page 2) for each monitor so that all channels have exactly the
same SPL output at the listening position. Although this can be done simply by listening to each channel one at a time and adjusting for relative levels, we recommend using an SPL meter and filtered noise (pink noise) to test each channel independently. Simply take a reading from each monitor, and then adjust all the monitors to match your lowest SPL reading. Your system levels should now be balanced for multi-channel surround.
The most significant thing to remember is that each room presents its own set of
acoustic variables. You'll want to experiment a bit to arrive at the best possible
sound for your room.

Problem: If you can't hear any sound...
• Repeat steps in the previous troubleshooting section above before continuing to
the next steps.
• Check to see if all other audio devices using the same AC outlet are still operat
ing.
• Make sure that:
• The audio source cable is plugged into both the source output and
the monitor input.
• The System Gain pot is turned up fully clockwise (+ 6 dB).
• The signal source (E.g. mixing console, work station, CD player, etc.) is
turned up to a level that can properly send a signal to the monitors.
• If one of the monitors is working. Exchange the audio input cable from the nonworking monitor to the working unit. This will determine whether it's really the
monitor, a faulty cable, or some other glitch in the audio chain.
• If the monitor is still not responding, it should be returned to the dealer that you
purchased it from or to KRK for servicing.
Problem: If the monitor suddenly stops working...
• Turn the monitor send 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. The V8 provides maximum circuitry protection against AC
power surges, amplifier overdrive, and overheating of the amplifiers. Turn the
monitor off then wait 30 minutes to allow the back plate to cool down. Turn the
power switch back on.
• Increase the volume to check for normal operation.
• If the monitor is still not responding, it should be returned to the dealer that you
purchased it from or to KRK for servicing.
9
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. It's also possible that the prob
lem lies some where in the electronics.
• Play some non-distorted source material at a low volume. Carefully cover the
tweeter (to block the sound) without touching the diaphragm. Is the woofer pro
ducing a clean sound? If there is not a clear tonal quality or any sound at all
then the woofer probably needs to be replaced.
• Cover the woofer so you can hear mostly the tweeter. Is the tweeter producing a
clear sound? If there is not a clear tonal quality or any sound at all then the
tweeter probably needs to be replaced.
• Once you have a better idea of what may be at fault then call us and speak with
someone in the service department. They will help you determine the best solu
tion to correct your monitors. The service department can be reached at (805)
584-5224,
Problem: The monitor hisses, hums or makes other loud noises...
