WARNINGS

This product complies with the EMC directive

(89/336/EEC) and the low-voltage directive

(73/23/EEC).This CLASS 1 apparatus must be

connected to anAC MAIN socket outlet with a

protective earthing connection

Thank you for your purchase of a Krell

Vanguard component. The Vanguard Family

includes the Vanguard Universal DAC w/Digital

Preamp Option (DAC), the Digital Vanguard

Integrated Amplier (DVI) and the Vanguard

Integrated Amplier (VIA).

This manual covers all three Vanguard models

and notes differences where appropriate.

The Vanguard Integrated Amplier can be equipped

with or without the Optional Digital Module that is

used in the Vanguard Universal DAC and Digital

Vanguard Integrated Amplifier.

All Vanguard models feature discrete signal paths

from input to output and employ a wide bandwidth

design with low negative feedback for sonic accuracy

throughout the frequency spectrum. All circuits up to

the driver stage operate in pure Class A.

Krell’s surface mount technology (SMT) means that

Vanguard components employ the most sophisticated

circuit designs possible without requiring the typical

space. SMT allows individual circuit elements to be

placed very close together. This shortens signal paths

and allows circuit elements to operate at the same

temperature, resulting in more accurate signal transfer

and enhanced reliability. This combination of sophis-

ticated circuitry and small space makes it possible to

design and manufacture a very high powered 200W

per channel amplier in a small enclosure. The Van-

guard is easy to operate and integrate into your

system. The remote control accesses all functions, and

remote control connection options allow the Vanguard

to be easily connected with other components.

The Theater Throughput (Digital Vanguard

Integrated Amplifier and Vanguard Integrated

Amplier) feature provides easy integration of these

models into a home theater system.

The optional digital module (Vanguard Integrated

Amplier) adds a full range of digital technologies

and connections that are already included in the

Vanguard Universal DAC and Digital Vanguard

Integrated Amplier.

WARNING: Do not place the component where it

could be exposed to dirt or excessive moisture. The

ventilation grids on the top and bottom of the

Vanguard must be unobstructed at all times. Do not

place ammable material on top of or beneath the

unit. When making connections to this or any other

model, make sure all components are off. Turn off all

system power before connecting the Vanguard to any

other component. Make sure all cable and speaker

wire terminations are of the highest quality, free from

frayed ends, short circuits or cold solder joints.

Unpacking / Placement / AC Power Guidlines

Open the shipping box and remove the top layer of

foam. You will see these items:

1. Vanguard unit and Accessories - Included

A. 1 AC power cord

B. 1 handheld remote control

C. 2 AAA batteries

D. 1 CD w/ owner’s reference

E. 1 warranty registration card

F. 1 trigger cable

G. 1 T-10 Torx Screwdriver

2. Carefully remove all items from the shipping box.

3. Place the preamplier and power supply in a safe

location and remove the protective plastic wrapping.

Place the Vanguard on a rm, level surface, away

from excessive heat, humidity, or moisture. The

Vanguard is a precision instrument and should be

handled with the utmost care when deciding where

it is to be placed and while it is being unpacked and

nally installed. Make sure the installation location

is dry and level, and able to provide adequate ven-

tilation. The Vanguard runs warm to the touch and

requires the bottom and top of the unit be free from

obstruction with good circulation of air. Allow a

minimum of 2 inches (5cm) above the unit for proper

ventilation, and at least one inch (2.54 cm) on each

side. Additional ventilation may be required when

the unit occupies the same space with other electron-

ics that generate heat, like power ampliers. Please

consult an authorized KRELL dealer or KRELL

Industries to insure proper installation guidelines.

The Vanguard is designed to work all over the world.

The operating voltage is determined at the factory and

is specically set to operate in the country of nal

destination. The Vanguard requires good clean power

and doesn’t require additional ltration. A 15 Amp

circuit is recommended for the Vanguard.

Note:

The Vanguard may not operate correctly when AC

regeneration or voltage conversion devices are

utilized, but at a minimum, they must be rated for the

maximum power consumption of the Vanguard.

Note:

Save all packing materials; if you need to ship the

Vanguard in the future, repack the unit in its original

packaging to prevent shipping damage.

lint-free cloth that has not been treated with chemicals

of any kind.

Please note the following: Do not use cleaning agents
