ENCORE TRUE DUAL MONO AMPLIFIER
Instructions

UNPACKING

The packing box for the Encore Amplifier
should arrive in good condition. Please
look for damage to the carton, although
this is most unlikely due to the strength of
the carton construction. Cut and open
packing carefully and save all foam pieces
and boxes for reuse in the event that the
unit must be shipped in the future.
Should the boxes become lost, please
contact the factory for replacement
cartons.
The carton should contain:
■ Encore Amplifier
■ 2 A.C. cables
■ torx wrench

INSTALLATION

Be certain that the amplifiers are installed
so that they have proper ventilation.
Placing the units in small, close-fitting
enclosures is not recommended. Room air
temperature should not exceed 122
degrees F./50 degrees C.

SELECTION OF AUDIO CABLES

Any high quality RCA cables may be used.
For balanced line connections, we strongly
suggest using Cello Strings cable made to
factory specifications. Improperly
constructed cables cause problems. It
takes equipment and experience to make
high quality balanced line terminations.
Cello Strings are available in any desired
length, with a variety of connectors, for
different system requirements.

CONNECTION

(See connection identification diagram
on page A1.)
1) Make sure the power switches located
on the rear panel of the amplifiers
are "OFF."
2) Verify that the amplifiers are set to the
same A.C. mains voltage as the A.C.
mains in your home or studio. (A.C.
mains voltage is labeled on the rear
panel of the amplifier.)
3) Connect the preamplifier outputs or
other driving equipment outputs to
the amplifier inputs located on the
rear panel.
4) Connect speaker cables to speaker
outputs on the rear panel. Be sure to
keep the spade terminal from rotating
while turning the the screw. Tighten
until there is zero play, then apply an
additional 1/8th turn to make the
connection snug.
CAUTION: Do not over-tighten, as
you will break the terminal strip.
5) Install the A.C. cords into the I.E.C.
mains connectors located on the
rear panel.
6) Connect the A.C. cords to the A.C.
outlets in your home or studio.
NOTE: Do not run A.C. cords, audio
signal or speaker cables under rugs or
sharp objects where they may be damaged.

OPERATION

CAUTION: Do not operate this device if
physical damage has occurred to unit, or
if the unit has been exposed to water or
other liquids, until proper repairs and/or
unit integrity tests have been effected by
authorized personnel.
1) Be sure all electrical connections are
correct and secure. Triple check them.
2) Turn peripheral units on first. Avoid
switching these units on and off while
amplifier is on.
3) Set volume control on preamplifier to
minimum.
4) Turn amplifier switches to "ON"
position.
5) Begin source material (turntable, tuner,
CD, etc.) and raise preamplifier volume
control to desired listening level. Enjoy!
NOTE: To remove amplifier from
system, turn down volume then turn
amplifiers "OFF" and reverse steps for
connection.

BRIDGED OPERATION

(See connection identification diagram
on page A2.)
One pair of Encore Amplifier units may
be used as a mono amplifier in bridged
mode. This provides four times the
regular power.
CAUTION: Bridged operation should
only be carried out with the recommen-
dation of the speaker manufacturer.
A bridging kit (P/N: 75-3410-00) is
required to operate Encore Amplifiers in
bridged mode. The kit may be purchased
from your Cello System Designer or
ordered directly from the factory.
