INTRODUCTION
Thank you for trusting YPSILON ELECT ONICS™. We assure you that you have made
an excellent purchase. Your amplifier is made only by the best and most reliable
materials and we guarantee it will offer you many hours of music enjoyment.
Every amplifier before delivery is thoroughly checked and measured for ensuring trouble
free operation.
Our goal is to offer you devices of the highest standard of build quality and sonic
performance.

PLACEMENT OF THE AELIUS POWER AMPLIFIER
AELIUS power amplifier is designed to reduce interference from external magnetic and
radio fields. Although placement is not critical, any magnetic fields should be avoided.
A solid and sturdy surface should be used as this amplifier has a substantial weight.
Take great care if planning on moving or lifting it and make sure that the weight is not
going to cause any injuries.
As it will generate quite some heat, in order to achieve the best operating conditions, it is
strongly suggested that there is good air circulation around the amplifier.

4
TAKING CARE OF YOUR AELIUS POWER AMP
When wanting to clean the amplifier always disconnect from the mains electricity and
use a clean, slightly damp cloth with no possibility of color running.
NEVER CLEAN AMPLIFIER CASING WHEN DEVICE IS CONNECTED TO
MAINS ELECTRICITY.
ALWAYS DISCONNECT FROM MAINS ELECTRICITY PRIOR TO ANY
SUCH ACT.
CONNECTING CABLES
For best results it is recommended to keep both the speaker and the input cables as short
as possible. Do not use longer cables than needed. For more information contact your
dealer or the factory.

5
CONNECTING TO THE MAINS OUTLET
Your amplifier has a description of the appropriate operation voltage on its back panel.
Please make sure not to overlook the specifications. In case you need to operate it in a
region with no complying voltage, contact your dealer or the factory. The power cable
that you will use must be at least 3 x 1.5 square mm and grounded to the mains outlet.
This device is Class I and the following safety rules apply:
According to guide 73/23/EEC for low voltage and guide 89/336/EEC (EMC) this
device is arked with .

CAUTION
DO NOT ATTEMPT TO
OPEN THIS DEVICE.
IN CASE OF
MALFUNCTION CONTACT
YOUR DEALER OR THE
MANUFACTURER
ONLY USE THE VOLTAGE
PRINTED ON REAR PANEL
WARNING: Before any maintenance or placement /connection takes place disconnect
the device from electrical outlets.
DISCONNECT THE DEVICE
WARNING: Never use electrical outlets without earth.
Use only electrical outlets that are earthed.

7
CONNECTIVITY INPUTS
AELIUS power amplifier is equipped with two connection inputs. One is XL and the
other is CA.
Do not connect and give signal to both inputs at the same time.
Only c nnect signal fr m pre-amplifier r h me cinema pr cess r.
RCA
XLR

8
BALANCED/UNBALANCED SWITCH
When using the CA connector turn the switch located on the back panel of the amplifier
to the UNBALANCED position. This is the input the manufacturer recommends.
NEVER use RCA inputs with the switch turned t BALANCED p siti n.
When using the XL input turn the switch to the BALANCED position .This is
recommended when using long cables from the pre amplifier.
GROUND/LIFT SWITCH
When the switch located on the back panel is turned to the LIFT position the ground
circuit is disconnected from chassis ground. This is used to eliminate ground loop in the
system and hum in the speakers. This is the recommended position.
When the switch is turned to the GROUND position the circuit ground is connected to
the chassis ground.

CONNECTIVITY OUTPUTS
There are two pure copper & gold plated connectors at the rear for connection of speaker
cables either by tightening the connector or by using a banana plug.
POWERING UP
With all the connections made you are ready to turn on the amplifier. The power on
switch is located at the backside of the amplifier. When it is switched on the front led
should be lighting.

10
BREAK IN PERIOD
Every amplifier has had an initial break in time of approximately 100 hours before
packing.
Still we suggest another 120 to 150 hours of breaking in before reaching its optimum
performance.
DESCRIPTION
The amp’s topology is Push-Pull. It’s input stage is valve and the output stage is with
mos-fets.
The input gain stage uses one C3g valve. The lifetime of the valves is specified at 10.000
hours. These valves have been matched to +/- 0,2 db.
When the valve lifetime passes contact your dealer or the factory for a new matched set.
IN CASE OF FAULT
In case of fault never open device. eturn to authorized technical agent or manufacturer.
In case of part changing only the exact same parts should ever be used and replaced by
authorized staff or manufacturer. Otherwise this device is out of Guarantee and will not
be compliant with international rules and regulations.

11
OUTPUT DC VOLTAGE& TEMPERATURE PROTECTION
AELIUS is equipped with an electronic circuit that will mute the amplifier in case of DC
occurring in the output. This is to protect the speakers from possible damage.
If this occurs contact your dealer or the factory.
There are 3 fuses in this amplifier. One in the mains and two for the DC protection.
These are 6,3 A slow blow fuses.
Note that in the input stage there should be no DC voltage occurring in any case. This
could cause the damage of the input valve.
If for some reason the temperature of this amplifier passes 90° C the output relay
switches off and only reopens when the device reaches 40° C.
