INSTRUCTIONS PERTAINING TO A
RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS
Read Instructions
The Owner’s Manualshould be read and understood
before operation of your unit. Please, save these instruc-
tions for future reference.
Packaging
Keep the box and packaging materials, in case the unit
needs to be returned for service.
Warning
When using electric products, basic precautions should
always be followed, including the following:
Power Sources
Your unit should be connected to a power source only of the voltage
specified in the owners manual or as marked on the unit. This unit has
a polarized plug. Do not use with an extension cord or receptacle
unless the plug can be fully inserted. Precautions should be taken so
that the grounding scheme on the unit is not defeated.
Hazards
Do not place this product on an unstable cart, stand, tripod, bracket or
table. The product may fall, causing serious personal injury and serious
damage to the product. Use only with cart, stand, tripod, bracket, or
table recommended by the manufacturer or sold with the product.
Follow the manufacturer’s instructions when installing the product and
use mounting accessories recommended by the manufacturer.
The apparatus should not be exposed to dripping or splashing water;
no objects filled with liquids should be placed on the apparatus.
Terminals marked with the “lightning bolt” are hazardous live; the
external wiring connected to these terminals require installation by an
instructed person or the use of ready made leads or cords.
No naked flame sources, such as lighted candles, should be
placed on the apparatus.
Power Cord
The AC supply cord should be routed so that it is unlikely that it will be
damaged. If the AC supply cord is damaged DO NOT OPERATE THE UNIT.
Service
The unit should be serviced only by qualified service personnel.

INSTRUCTIONS RELATIVES AU RISQUE
DE FEU, CHOC ÉLECTRIQUE, OU
BLESSURES AUX PERSONNES
Veuillez Lire le Manuel
Il contient des informations qui devraient êtres comprises
avant l’opération de votre appareil. Conservez S.V.P. ces
instructions pour consultations ultérieures.
Emballage
Conservez la boite au cas ou l’appareil devait être
retourner pour réparation.
Attention:
Lors de l’utilisation de produits électrique, assurez-vous
d’adhérer à des précautions de bases incluant celle qui
suivent:
Alimentation
L’appareil ne doit être branché qu’à une source d’alimentation
correspondant au voltage spécifié dans le manuel ou tel qu’indiqué sur
l’appareil. Cet appareil est équipé d’une prise d’alimentation polarisée.
Ne pas utiliser cet appareil avec un cordon de raccordement à moins
qu’il soit possible d’insérer complètement les trois lames. Des
précautions doivent êtres prises afin d’eviter que le système de mise à
la terre de l’appareil ne soit désengagé.
Risque
Ne pas placer cet appareil sur un chariot, un support, un trépied ou une
table instables. L’appareil pourrait tomber et blesser quelqu’un ou subir
des dommages importants. Utiliser seulement un chariot, un support,
un trépied ou une table recommandés par le fabricant ou vendus avec
le produit. Suivre les instructions du fabricant pour installer l’appareil et
utiliser les accessoires recommandés par le fabricant.
Il convient de ne pas placer sur l’appareil de sources de flammes
nues, telles que des bougies allumées.
L’appeil ne doit pas être exposé à des égouttements d’eau ou des
éclaboussures et qu’aucun objet rempli de liquide tel que des vases
ne doit être placé sur l’appareil.
Les dispositifs marqués d’une symbole “d’éclair” sont des parties
dangereuses au toucher et que les câblages extérieurs connectés à
ces dispositifs de connection extérieure doivent être effectivés par un
opérateur formé ou en utilisant des cordons déjà préparés.
Cordon d’Alimentation
Évitez d’endommager le cordon d’alimentation. N’UTILISEZ PAS
L’APPAREIL si le cordon d’alimentation est endommagé.
Service
Consultez un technicien qualifié pour l’entretien de votre appareil.

Introduction
Your new Yorkville AP1020 power amplifier has been designed and built to provide years of trouble free performance. The AP1020 starts
with the field-proven reliability of our Audiopro amplifiers and customer requested features like switchable limiters and a Mono/Stereo/Bridge
switch. We’ve made the AP1020 power configurable, (see Power Configuration), which makes it one of the most versatile amp in its class.
The AP1020 weighs a comfortable, but solid, 39 pounds; it fits into two rack spaces and reproduces music with over 1200 Watts of
headroom. It will drive reactive phase shifted loads with no difficulty - even though it is fully protected from accidental short circuits.
Our design goal was to create an amplifier, which would do exactly what an amplifier should do: reproduce music with great power,
complete reliability, and uncompromising signal fidelity. We think you will agree that the Yorkville AP1020 does exactly that. We hope
this manual will provide answers to any questions you may have about the features, controls, and characteristics of this amplifier.
Inputs
Balanced Inputs
Either XLR or two circuit Ring, Tip, Sleeve stereo ¼-inch PHONE
cords may be used. Each channel’s XLR input is internally par-
alleled with its phone input: The Tip of the Channel A Phone
input is connected to pin 2 of its XLR input, the Ring is con-
nected to pin 3, and the Sleeve is connected to pin 1. Pin 2 is in
phase, pin 3 is 180 degrees out of phase, and pin 1 is ground.
We recommend using balanced lines for the best hum-free per-
formance, particularly when chaining multiple amplifiers.
Unbalanced Inputs
Ordinary single circuit 1/4 inch phone plugs may standard
be used to connect unbalanced signals. Important Note: Such
plugs effectively connect the ring terminal to sleeve ground,
so they work correctly. However, if you use a ¼-inch stereo
phone plug on an unbalanced line, you short the ring ter-must
minal to the sleeve terminal, otherwise the sensitivity will be 6
dB lower than is specified! (The same applies to the XLR input;
to connect an unbalanced source via the XLR input, you must
connect the signal to pin 2 and ground pin 1 and pin 3).both
Remote Referencing
You can approach balanced performance with unbalanced sources
by utilizing the remote reference feature of the AP1020 Connect a
balanced cable to the AP1020 just as you would if you were run-
ning a balanced line. At the other end, connect pin 3 and pin 1
together, (or connect ring to sleeve if you are using a phone plug
cable), and plug this modified end into your unbalanced piece of
equipment. This connection enables the AP1020’s input to “look”
down the cable directly at the output jack of the unbalanced equip-
ment. Any hum voltage generated across the cable’s impedance
will be attenuated by the common mode rejection of the AP1020.
Driving Multiple AP1020s
In large installations it is often desirable to operate many amplifi-
ers in tandem. Since each channel’s XLR input is internally paral-
leled with its phone input, you may use the remaining input jack
as an output to the next amplifier. Obviously you will need both
XLR-to-XLR and phone-to-phone patch cords if you are going to
tandem more than two amplifiers.
Note: These patch cords must be balanced whether the
input signal is balanced or unbalanced!
Ground Switch
Switching the ground switch on the rear
panel will disconnect chassis ground from
circuit ground. Safety ( ) ground is still earth
connected to the chassis. We do not rec-
ommend lifting the ground strap unless you
are experiencing problems with ground
loop hum in multiple amplifier setups
where lifting the ground straps of all but
one amplifier cures the hum problem.
CAUTION: Sometimes hum problems are an indication of
improper AC wiring somewhere else in your system. Don’t
just doctor the symptom by lifting grounds. Fix the cause by
making sure that the proper electrical wiring safety regula-
tions have been adhered to.
Modes
The can be configured for , Stereo, or Bridged AP1020 dual-Mono
Mono operation via this rear panel Mode switch. The following is
a description of each mode:
Mono Mode
• Channels A and B inputs are paralleled
• Each gain control adjusts the signal level for its
respective channel
• Output signals are of .equal phase
• Two loads are driven.
• Loads are connected between the black and red
post on each channel.
