The Penta has been developed for home-
cinema systems. Ceratec product range also
offers necessary add-ins - front, centre, rear
speakers and subwoofers.
Penta is a high-end 5.1 amplifier.
Consequently, it should be used only with
appropriate electronics. Should you have any
questions or doubts in this respect, please do
not hesitate to contact your Ceratec dealer.
Nowadays there is a strong tendency either to
substitute stereo systems with home cinemas
or to extend stereo systems and change it into
a home cinema. For your convenience we
provide a brief overview of modern multi-
channel recording standards:
Dolby®ProLogic
Dolby ProLogic processor – included in an amplifier
or in a receiver – transforms the sound for multi-
channelling so that the sound and the picture match.
For example, in a movie the sound follows the
motion of an actor or object.
Dolby ProLogic is an analogue technology that can
carry several channels – front, rear, centre and a
subwoofer. That is why such a system is the best
choice for a cost effective home cinema of
acceptable quality.
Dolby®Digital
Dolby Digital is a top quality multi-channel technology.
Originally developed for professional cinema theatres,
nowadays it comprises an integral part of best home
cinemas.
Unlike Dolby ProLogic, Dolby Digital carries all sound
information digitally, using a separate wire for every
channel. When combined with proper speakers and
amplifiers, Dolby Digital provides natural playback of
music, voices and sound effects.
DTS®
DTS is another digital recording format offering multi-
channel sound. Just like with Dolby Digital, information
for front and rear speakers, a centre speaker and a
subwoofer is recorded on separate tracks. DTS
processes more refined information than Dolby Digital
and often gets even higher quality ratings. Originally
DTS was also developed for professional cinema use.
The Penta 5.1 amplifier is perfectly suitable for
digital multi-channel Dolby Digital and DTS
systems.
Operation Principles
5 channel power amps with gain control (remote)
for direct use with DVD player (Dolby Digital/DTS).
Further recommendations and set proposals
please refer to technical data catalogue.
Packaging and Damage in Transit

important details; therefore the device is pretty

Installation and adjustments
Before connecting the main power cable to the
amplifier, make sure that the voltage switch (5)
is switched to the correct voltage level.
Install first the cinch connection cables from your
5.1 Decoder to the Penta 5.1 amplifier. After this
you can install the connection to the speaker set.

If all connections are checked once more, take
care that the volume level is not on maximum,
before switching the main power switch (7) on the
backside of the Penta. If now the LED indicator (F)
turns to green, than the Penta is ready for use.
Now you can do the fine tuning with the prelevel
regulators, which are also located on the backside
of the amplifier.
Warnings

open the device. In case of malfunction, please
contact your Ceratec dealer.

FUSE –Main Fuse (6)
In the power connector there are
main, as well as secondary fuses.
It is possible to replace the fuse
only with a fuse of a similar
design and similar characteristics! Use of
other fuses may stop warranty.
VOLTAGE SELECTOR – Mains Voltage Switch (12)
The Penta 5.1amplifier can be used in all
countries and is good both for 110/115 and
220/230 V. Before the first operation, please
make sure that Mains Voltage Switch is set to
the value accepted in your country.
Beware: Switching can be
performed only when the power
cable is disconnected.
If the switch is in "115 V" position and the
system is connected to 230 V, serious
damages will happen!
Troubleshooting
Ceratec chooses for materials of the highest
quality and thinks over the design of each
model in detail. This provides all necessary
conditions for long-term operation without
maintenance. However under certain
conditions there can appear interferences
caused by external reasons:
•Background noise. The reason for
background noise, as a rule, is mains
malfunction which in most cases can be
easily repaired.
Please wait till Penta switches on, then unplug
all home cinema devices. If the reason is one
of these devices, insert the power cable plug
into the socket in the opposite direction. If
necessary, do the same with the Penta power
cable.
