6. PRESET selector
This switch allows the selection between four different DSP settings (equalisation curves, dynamics etc.), suited to four
different uses.
FLAT
Suited for live sound reinforcement, this preset includes a dynamic equalizer.
When the system is used at low or mid level, the deep lows and the top highs are
enhanced, resulting in an deep and detailed response, ideal for the reproduction
vocals and live instruments. When the level of the signal sent to the amplifier is
increased and it approaches the limiter action, the enhancement of low and high
frequencies is reduced, thus increasing the dynamics and the efficiency of the
whole system. Together with that, the mid-high frequencies are slighlty decreased,
thus reducing the harshness that can occur when the sound is very loud and
making it more enjoyable.
DJ
Suited for the reproduction of recorded music, this preset includes a dynamic
equalizer.
When the system is used at low or mid level, the deep lows and the top highs are
enhanced, resulting in an richer and brighter response, ideal for the reproduction
of background music or for a DJ set. When the level of the signal sent to the
amplifier is increased and it approaches the limiter action, the enhancement of low
and high frequencies is reduced, thus increasing the dynamics and the efficiency
of the whole system. Together with that, the mid-high frequencies are slightly
decreased, thus reducing the harshness that can occur when the sound is very loud
and making it more enjoyable.
SPEECH
This preset has been designed for applications (such as conferences) where a
dynamic microphone is directly connected to the speaker input and it provides the
correct equalization for enhancing the human voice intelligibility.
MONITOR
Suited for the use of the system as a stage monitor, in this preset the deep lows
are attenuated in order to compensate the floor position, the mid-low frequencies
are enhanced for a better presence and the mid-high frequencies are reduced for
an improved feedback rejection.
7. SIGN / LIMIT indicator
GREEN LED illuminates to indicate the presence of the signal at the amplifier input.
RED LED illuminates when the internal amplifier's output is limited or when the
input AD converter clips.
NOTE: When this LED flashes reduce the input signal level.
NOTE: If you hear annoying and excessive distortion check the MIC/LINE switch position, most probably you are sending
to the speaker a high line level signal using the MIC sensitivity, so switch it to LINE sensitivity.
8. ON indicator
GREEN LED: when lighted indicates that the amplifier has been turned on and AC power is available.
9. POWER switch
Speaker is "ON" when the switch is in the "I" position.
NOTE: When you shut down your equipment, turn off the speaker first. When powering up, turn on the speaker last.
10. AC~ socket
Here's where you plug in your speaker's mains supply cord. You should always use the mains cord supplied with the
speaker. Be sure your speaker is turned off before you plug in the cord.
11. FUSE holder
Here is placed the mains protection fuse. Please follow the instructions on page 9 of this manual to replace it.
