Warm Up

The REF1000’s sonic performance will start to stabilize after approximately forty

(40) hours of continuous power up. We recommend that the REF1000 remains

powered for optimum performance.

The e.One Series REF1000 is a mono

amplifier designed to deliver over

500 watts into 8 ohm loads and 1000

watts into 4 ohm loads. The REF1000

has current drive capability for virtu-

ally any loudspeaker load down to 2

ohms. This is achieved in a compact

and elegant product through our

adaptation of the latest analog

switching amplifier and power sup-

ply technology from the ICEpower

group.

This technology brings unprecedent-

ed performance gains in absolute

musical performance. The regulated

power supply and fully balanced

analog switching amplifier architec-

ture liberates your loudspeakers to

perform at their best. The ultra-low

noise operation insures that the most

subtle of musical expressions comes

through with palpable clarity.

The superb measured performance

insures that harmonic and intermod-

ulation distortion don’t interfere with

the pristine beauty or raw power of

the musical message.

The e.One series amplifiers from Bel

Canto insure that you fully experi-

ence the musical intensity and beau-

ty of your favorite artists.

Design Features

Warning!

Do not connect power to this amplifier yet!

This amplifier, like any electrical component, can be dangerous and cause injury

unless correct handling procedures are observed and used. Before powering this

preamplifier it is necessary to read and follow proper procedures concerning its

setup and use.

Any tampering of internal parts will immediately void your warranty.

USA customers: For Warranty Coverage complete and mail the Owner's

Registration Papers immediately.

Unpacking

The REF1000 box contains:

1 – REF1000 User's Guide

1 - Power Cable for connection

to utility power [1.85m,

6' long]

1 – REF1000 Amplifier.

1 - Owner's Warranty /

Registration Sheet

Carefully inspect your new unit and

check for shipping damage. If there is

any damage, or if any piece is miss-

ing, please contact your dealer, dis-

tributor or Bel Canto Design.

Save all packing materials as the

packing is specially designed to pro-

tect the amplifier for shipping or

transporting it. If you lose or damage

the packing materials or carton,

please contact your dealer or distrib-

utor before attempting to transport

the preamplifier.

The REF1000’s power supply is pre-

set for the proper AC line voltage

before you receive it. The power

cable will have the correct plug for

your local power system. If you

believe this is not true, please con-

tact your dealer immediately. Do not

attempt to alter or change power

settings yourself. This will void the

warranty.

REF1000 Rear Panel

Rear Panel Connections

Never Connect Either the Positive or Negative Speaker Output to

Any Ground Contact!

Connecting any Speaker Output on the REF1000 to Ground will cause the amplifi-

er to go into protection and could damage the amplifier and void the warranty.

1) Power Switch: Power is on when the

switch is toggled to the I position

and off in the O position.

2) Input Connections and RCA/XLR

switch: When using RCA cables for

the input insure that the RCA/XLR

switch is pressed in to the RCA posi-

tion. When using XLR cables insure

that the switch is out in the XLR

position. This will generally insure

ideal grounding and minimize

ground noise from interfering with

the audio signal.

3) Output Connections: Attach your

loudspeaker to the output connec-

tors, insure that the polarity of each

speaker is correct and the same so

that no phase inversion can occur.

Never Connect Either the Positive or

Negative Speaker Output to Any

Ground Contact!

4) IEC power cord jack: Connect a

heavy gauge power cord from

this jack to the wall power supply.

Note the power setting indicated

on the back of the amplifier before

connecting the power.

When all connections to and from the

amplifier have been made then double

check everything, insure that the pre-

amplifier is powered on and set to a

Mute setting and power on the

REF1000.

REF1000 User’s Guide 1105 Rev.A

Front Panel Indicator Lamp

What to do if there is hum or ground noise:

The small blue LED lamp indicates that

the power is connected to the REF1000

and that the power switch is in the ON

position. If the amplifier detects a fault

or short circuit in the output connec-

tions then it will go into a protection

mode and stop playing. If this occurs

toggle the power switch to the OFF

position and check the speaker cabling

to insure that no speaker output is

either shorted together or connected to

a ground. When you are certain that

the loudspeaker cabling is correct,

power the unit ON again and insure

that the Blue lamp is lit and that music

will play.

Fuse Protection

There is an internal fuse protection on

the REF1000. If the power switch is in

the ON position, the power cable is

connected to a functioning power out-

let at the correct voltage and the Blue

lamp is not lit,this indicates that the

internal fuse may have blown. If this

occurs contact your dealer, distributor

or Bel Canto for service. There are no

user replaceable fuses or other parts.

Opening the chassis will void your

warranty.

1) Check that the RCA/XLR switch is in

the correct position for the type of

connection being used.

2) Insure that the preamplifier or any

source components are not produc-

ing hum by setting the preamplifier

to a MUTE or Standby setting.

3) The design of the REF1000 reduces

the chance for ground loop induced

hum but we still recommend that you

use shorter interconnect cables to the

preamplifier and connect all power

cables to a common outlet box or

power conditioner unit to reduce the

possibility for ground current noise

being induced into the audio signal

path. If you choose to power your

source and preamplifier components

from a different AC supply than used

for the REF1000 amplifiers, we recom-

mend that you use a high quality bal-

anced XLR cable driven from a true

balanced XLR preamplifier output. We

do not recommend that you resort to

‘cheater plugs’ or some other means

to disconnect the power ground from

the REF1000 as this may lead to dan-

gerous operation and void the warran-

ty.
