TROUBLESHOOTING
The product does not switch on
Check the main power supply outlet plugging an
other device in (a lamp for instance).
If the power supply outlet does not work properly,
check the connecting and automatic safety
protections of your electric circuitry. For further
assistance, contact a professional electricity
technician.
Remote control not working
On one electronic device: Check that the IR
receiver (close to the display) is not obstructed.
Use the remote control in the axe of the front panel.
On all the electronic devices: Check the batteries
of the remote control.
The remote control behaves in a very strange
way: Check the batteries
No sound from the speakers

a MM cell, selecting the MC choice of the sensitivity
selector.

Overheat problem
The amplifi er automatically goes to protection mode
while overheating.
This may come from a lack of air fl ow that prevents
from a proper cooling of the products (check
that all openings of the cabinet are free from any
obstruction).
This may come from a high ambient temperature.
The amplifi er may have been exposed to a heat
source (sun ray, heating system...) that may limit
the cooling system effi ciency.
In any case, once the amplifi er is back to a normal
temperature, it shall run smoothly again. If the
problem occurs often, contact your local CARAT
technical service.
Low impedance of the speakers
(or more than 2 pairs)
The amplifi er is equipped with an auto protection
against low impedance. It has been designed to be
connected to 2 pairs of 4 ohms speakers.
NEVER CONNECT MORE THAN 2 PAIRS OF
SPEAKERS ON THIS AMPLIFIER
Sound only from one side
Check that the balance is not fully set up on one
side (in this case, sound is barely audible, but still
existing)
May this happen with all the sources, check the
connections of your speakers.
May this happen with only one source, check the
connection of this specifi c source.
May this happen with the turntable, the problem
may also come from the connection of the cell.
Weak bass, diffuse stereo image
One of the speakers may be out of phase:
Check connection on all speakers of the system.
Weak level on the turntable
Your turntable is connected on a high level input
(CD, Aux., Tuner...).
Connect the turntable on the Phono input.
Your cell is a MC type and the sensitivity switch of
the back panel is on MM. The cell of the turntable
is not properly set up : check the user's manual of
your turntable to fi x this issue.
WARNING : always lower the volume when
modifying the set up.
