Introduction We would like to thank you for buying a product in the XTZ EDGE series. The electrical design of the EDGE
series offers the ultimate sound reproduction. In order to utilize your new device in the best possible
way, please read this manual carefully before using it for the rst time. It often takes some effort and
patience to make a HiFi system sound its best. If you do not have any previous experience from this kind
of installation, please feel free to contact our free of charge support and we will help you.
- Series name - Power Amplier - Power level
- Two channels
Safety instructions Switch off your amplier before connecting the speakers. Make sure that the speaker wires are tightened
and have a strong connection to the speaker terminal and amplier terminal.
Make sure that the electronics are not exposed to direct sunlight or strong articial light. Listening
to high sound pressure levels over a longer period of time may harm your hearing. To avoid hearing
damage do not listen to high sound pressure levels over a longer period of time.

Important Safety Instructions

Quick Setup The initial setup of a XTZ product is relatively easy. Please take your time reading the guidelines and more
detailed instructions on the following pages of this manual after completing the rst four steps as listed
below.
1. Connect your speakers to the SPEAKER-OUTPUT terminals of the EDGE A2-400.
2. Connect your pre-amplier’s PRE OUT to the EDGE A2-400 rear panel’s INPUT port.
3. Make sure to set your pre-amplier’s volume level to minimum.
4. Connect the AC cord to the EDGE A2-400 AC power input and then plug into an AC outlet.
5. Set the switches in the on the back of the EDGE A2-400 as you wish. If the device is used in “AUTO ON“
mode, it will detect incoming signals and automatically switch from STANDBY to ON. If used in “ALWAYS
ON“ mode, the device will always be in ON mode. There is also the option of using “TRIGGER” if your
pre-amplier has 12V trigger output.
6. Set the POWER switch on the rear panel to “ON” in order to turn the EDGE A2-400 to standby mode. The
standby LED indicator on the front panel will illuminate red in case you use the device in “AUTO ON“ mode
and green in case you use it in “ALWAYS ON“ mode.

Placing the unit Allow adequate ventilation. Do not place the unit on a soft surface like a carpet. Do not place it in an
enclosed position such a bookcase or cabinet that may impede the air-ow through the ventilation slots.
AC Power
(220V / 110V)
To power the unit, connect the supplied power cord to the unit and a standard AC power outlet. The unit
recognizes the prevailing voltage automatically so you don‘t need to adjust it to your local voltage level. In
standby mode the EDGE A2-400 consumes less than 0.3 Watts (EU mains).
Connections
(Noise issues)
To always ensure safe use of the amplifier and speakers, only connect and disconnect signal
cables and speaker cables when the amplier is shut off via the main power switch on the back.
Always use signal cables and speaker cables that are as short as possible and of good quality.
Long signal cables of poor quality work as antennas, and might in some cases create noise.
Always connect using the correct phase, from the plus (+) pole on the amplier to the plus (+) pole on the
loudspeaker and respectively for the minus (-) pole.
Earth ground is often used to reduce noise from electrical interference from outside the casing, however
in some cases several electrical devices which are connected to the same grounding grid can create loops
that pick up interference i.e. ground loops. There are a couple of ways to x this problem:
• Use the same power strip / power outlet for the interfering equipment.
• Use as short as possible signal cables of high quality to minimize resistance and impedance.
Cleaning the
product
Switch off all components in your system when cleaning any of the m. Clean the surfaces with a soft dry
cloth only.
