ON / OFF
A sound system should be switched on sequentially.
Switch on the self-powered units last in your sound system
(switch on the subwoofer before the mid-high system). Switch
on the sound sources such as CD players or turntables, then
the mixer, then the processors, and finally the selfpowered unit.
If you have several units, it is recommended that you switch
them on sequentially one at a time.
Follow the inverse order when switching off, turning self-
powered units off before any other element in the sound
system.
Disconnect the device by removing the mains connector from
the mains socket on the amplifier´s rear panel. The mains
connector and mains socket must always be freely accessible
and never covered or blocked in any way. The mains cable can
be detached from the device by disconnecting the standard
IEC connector.
I
MPORTANT: Do not disconnect the unit while in use.
Ensure that the device is disconnected from the mains by
observing that the DISPLAY is turned off.
Overload Display indicators (limit and Input Clip)
In the main screen when input signal levels are too high on
the left side (input channles) the meters will display “input
clip”:
If the input levels are in between the limits but the output
level gain is too high, the right meter will display “limit”.
Please keep the gain structure of the system within the limits
(no INPUT clip and NO LIMIT shown) in order to keep the
system safe and free of distortion. To maintain that gain
structure below reaching LIMIT or INPUT clip, besides the
level of the source (Master Output of the console etc) the user
can adjunt levels with the input knob controls (2) and the Master
Volume control (1):

Equalisation
The unit does not need external settings of equalisation to
produce quality sound.
In fact the unit has an internal 3 band equalizer
(Low/Mid/High) adjustable by the user. Besides this, keep
in mind all the possible presets available in the DSP (live,
dance, bboost, etc).
Overheating
This equipment does not normally overheat during
normal conditions of use. It has been designed and tested
at DAS Audio Laboratories to work under hard thermal
conditons with high output levels (limit conditions). If
overheating occurs, the unit protects itself by lowering the
output power. You should then find out why and if
necessary contact an authorised service center for
technical assistance.
Normally it is enough just to let the unit cool down after
you have corrected the problem so that the system
functions properly again.
Low mains voltage
If mains voltage falls below the shutdown voltage for the
unit, it will stop playing. When acceptable levels are
regained, the unit will switch back on automatically.
For altea 400 series the shutdown level is around 90V.
For altea 700 series the shutdown level is 80V.
Therefore the current consumed by a 115V version is
double the 230V version to achieve the same acoustic
power level.
