Introduction

Congratulations on your KRK purchase! And welcome to the growing family of KRK owners.
Growing demands on music recording industry professionals have created the need for better monitor performance

at more affordable prices. The V-Series class of Powered Studio Monitors was created to address these needs.
Please take a few moments to review the information in this guide.

FEATURES OVERVIEW

1. Neutrik® Combo Connector accepts XLR,
¼” phone and TRS connectors

2. System Gain Control adjusts input
sensitivity of the monitor

3. High Frequency Adjustment allows 3-step
adjustment of high frequencies

4. Low Frequency Adjustment allows 3-step
adjustment of low frequencies

5. IEC Power Entry Module contains the
following 3 parts:

~ On/Off Switch
~ Fuse Block/Voltage Selector
~ IEC Power Connector

Systems Controls

SYSTEM GAIN

The input sensitivity is adjusted (counterclockwise reduces sensitivity) with the rear panel mounted System Gain
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 V8 in a surround system and 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. filtered noise generator and SPL meter)

HF ADJUSTMENT

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. (See additional information in Installing Your Monitors section on page 4.)

LF ADJUSTMENT

Low Frequency turnover is set to 45Hz, 50Hz, or 65Hz by a rear panel mounted 3-position 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.)

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.

NOTE: MAKE SURE THAT THE VOLTAGE INDICATOR FOUND IN THE MIDDLE PORTION OF THE IEC MAINS
CONTROL IS SET TO THE CORRECT VOLTAGE SETTING FOR YOUR VOLTAGE.

CHANGING VOLTAGE

To change the voltage, remove the power cord, pry off the fuse block with a small flathead screwdriver (look for
indent on the left inside of the power cord insert). Slide the circuit board out of the fuse block, rotate 180º and
reinstall the fuse block. Please note when making fuse changes, the fuses will have to be replaced. (see

Changing Fuses section below) Make sure and align the white arrow with the raised arrow located on the
power entry module before reinstalling. Check to see if the correct voltage can be read from left to right in the

voltage window before powering up.

CHANGING FUSES

Under normal operation the fuses should not blow. A blown fuse usually indicates an overload or fault condition.
To change the fuse, remove the power cord, pry off the fuse block with a small flathead screwdriver (look for
indent on the left inside of the power cord insert) and change the blown fuses.

• 100~120VAC use 4 amp 250V 5mm x 20mm fuses

• 220~240VAC use 2 amp 250V 5mm x 20mm fuses

If the fuses blow immediately upon power up, this indicates a fault condition and the monitor should be
returned to KRK for repair.

NEUTRIK® COMBO CONNECTOR

3

The Neutrik® Combo connector accommodates ¼” phone plugs, XLR, TRS. Please note that PIN 2 is hot! If you are
using an unbalanced connection 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.)

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 V8’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.
