32 Vantec series User's Manual
Vantec Series | Amplifier
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 self-powered 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. 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
PowerCon NC3FCA connector. Always disconnect the device by removing the mains connector
from the mains socket before detaching the mains cable at the PowerCon NC3FCA connector.
Power can be daisy chained via the NC3FCB output connector (see details on product label).
IMPORTANT: Do not disconnect the unit while in use.
Ensure that the device is disconnected from the mains by observing that the ON LED is
turned off. Please note that the ON LED can stay on for several seconds after the mains
power has been disconnected.
Overload LED indicator (VANTEC-18A)
This device has an indicator (LIMIT LED) that lights when the signal is excessive.
The indicator should not be lit continuously. This distorts the signal (quickly fatiguing your ears)
and may damage the speakers. Therefore, it is recommended that you never work with this LED
on; at most it should blink only occasionally.
Overload Screen indicators (VANTEC-12A / 15A / 215A)
In the main screen when input signal levels are too high on the left side the meters will display
“input clip”.
If the input levels are in between the limits but the output level gain is too much the right meter
will display “limit”.
Equalisation
The unit does not need extreme settings of equalisation to produce quality sound. Avoid high
levels of gain on the equalisers. Gain values above +3 dB on a console’s EQ are not recommended.
Overheating
This equipment does not normally overheat during normal conditions of use. When overheating
occurs, the unit protects itself. You should then find out why and if necessary contact an
authorised dealer 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.
Therefore the current consumed by a 115V version is double the 230V version to achieve the
same acoustic power level.
