Working with presets
The electronic board has provisions for 4 different
memory setings - or PRESETS.
Each preset contains a different algorythm that modifies
the behavior of the frequency transfer, between source
and amplifiers, thus changing the frequency response.
We suggest using PRESET number 1, which is the
"flat" setting in semi-reverberant rooms, such as a well
furnished home.
"Flat" means that all frequencies are reproduced at the
same reference level, without changing the sound
balance of the source material.
However, in some instances, it may be desirable to
modify the frequency transfer characteristics to
compensate for different listening environmemts.
For this reason, we implemented 3 additional
PRESETS.
Subwoofer integration
Preset 4 is designed to restrict the low frequency output
of the loudspeakers. This setting can be used with or
without a subwoofer or bass cabinet, for example, if the
acoustic of the room over emphasize low frequencies.
With the addition of a subwoofer or bass cabinet, it is
advisable to reduce the low frequency output of the
main speakers, which is the purpose of this setting.
By reducing output below 60 Hz, this preset makes it
easier to properly integrate the output of 1 or 2 bass
cabinets to the main loudspeakers, by restricting the
amount of overlapping frequencies.
Doing so also improves the dynamic range of the total
system, since the woofers are releived of low bass duty
and therefore can reproduce a smaller portion of the
bandwith with greater authority.
Vivid
In the setting (PRESET 2), both low and high
frequencies are tilted, and bass and treble output are
raised to compensate for the way our brain interpret
different loudness levels.
This would be the preferred setting of someone who
most of the time listens at less than "realstic" or "live"
sound level.
Studies have shown that at lower playback level, our
hearing is more sensitive to midrange frequencies.
Therefore, by raising the output of lows and highs
relative to mid frequencies, the sound appears more
balanced at lower playback levels.
This setting should not be used at high playback levels
as it reduces the dynamics of the system.
Low boost
This setting raises the playback level of low
frequencies, in the range of 60Hz to 100Hz and will
compensate for rooms that are too "bright" sounding.
"Brightness" is a function of room acoustics, where the
room does not absorb higher frequencies, for example,
an uncarpeted room will sound brighter than a room
with plush carpet, stuffed furniture, etc.
In this situation, a boost of lower frequencies is
desirable as it balances the sound spectrum in the
room.
Custom presets
It is possible to precisely adapt the transfer
characteristics to suit a perticuliar listening
environment, or personal preferences. This is beyond
the scope of this manual, but keep in mind your
Arteluthe product can be customised in many ways by
factory trained personel. Consult your dealer or factory
regarding this possibility.
