IMG STAGELINE PSUB-215 Manual De Instrucciones página 7

satellite output provides the signal (without bass range)
for the satellite speaker system. The feed-through out-
put allows connection of another active speaker system.
4 Setting-up and Connection
1) Place the speaker system on the floor as desired. It
is possible to place a satellite speaker at a certain
distance above the speaker system. For this pur-
pose, insert an adapter for speaker stands (e. g.
from the PAST series of "img Stage Line") into the
stand sleeve on the upper side of the PSUB-215
and place the satellite speaker on top.
2) As a signal source, connect an audio unit with line
output level (e. g. mixer, CD player, MD or cassette
recorder). Connect the mono output or a stereo
channel of the signal source to the balanced jack
INPUT (4). (Feed the other stereo channel to a
second active speaker system.)
3) At the balanced XLR output LINE OUT LINK (3),
the input signal fed through is available. This output
allows connection of the input of another active
speaker system.
4) Connect the respective active satellite speaker
system to the balanced output LINE OUT SAT (11)
or connect a passive satellite speaker system via a
corresponding amplifier.
5) Finally connect the supplied mains cable to the mains
jack (13) and to a mains socket (230 V~/50 Hz).
5 Operation
Any adjustments and sound evaluations must only be
made in connection with the satellite speaker. The
sound should be evaluated at the final place of hearing
where a second person at the active subwoofer should
be instructed to perform an optimum adjustment.
CAUTION Never adjust a very high volume. Per-
manent high volumes may damage
your hearing! The human ear will get
accustomed to high volumes which do
not seem to be that high after some
time. Therefore, do not further increase
a high volume after getting used to it.
1) With the control X-OVER (8) adjust the crossover
frequency between the subwoofer and the satellite
speaker (the lower the crossover frequency, the
more difficult the acoustic localization of the sub-
woofer; the higher the crossover frequency, the more
powerful the bass support). As a guidance, refer to
the frequency range of the satellite speakers.
2) Switch on the signal source connected.
3) Prior to switching on the subwoofer, set the control
BASS LEVEL (9) to zero to prevent switching noise.
Then switch on the subwoofer with the mains switch
POWER (12): The upper LED AMP. ON/PROT. (2)
will show red for a few seconds after switching on
(protective circuit activated, unit muted) and then
change to green (normal operation).
4) Adjust the volume with the control BASS LEVEL.
From a certain volume, the lower LED NORM. (2)
will light up to the rhythm of the music.
If the level is too high, the central LED LIMIT. (2)
will light up to indicate that the integrated limiter cir-
cuit is active. The limiter circuit serves to limit the
signal level: If the level exceeds a maximum value
defined, it is adjusted downward to this value by the
limiter circuit. If the LED LIMIT. should light perma-
nently, turn back the volume control correspond-
ingly.
5) Press the button SUBBOOST (5) to boost the lower
bass range, if required. With the subboost function
switched on, the LED next to the button will light up.
6) Subsonic sound or other low-frequency interfer-
ence will be suppressed by connecting the sub-
sonic filter: Press the button SUBSONIC (7). With
the filter switched on, the LED next to the button will
light up.
7) When setting up several speaker systems, the
sound waves of the systems may show a different
phase at the place of hearing. This may cause
undesired attenuation of certain frequencies. To
balance this, the active speaker system is equipped
with a phase reversal switch [button PHASE (6)]
which allows to reverse the phase of the audio sig-
nal by 180°. Set the control BASS PHASE (10) to
zero first. Then test both positions of the button
PHASE – pressed (LED next to it lights up) or
unlocked – and choose the position offering the
best reproduction.
8) Adjust the phase for the subwoofer with the control
BASS PHASE. According to the acoustic conditions,
this adjustment will be more or less audible. The
phase can best be adjusted during a music piece
with an electric bass, a contrabass, or a deep bass
voice. Set the control BASS PHASE to the bass
reproduction of the highest volume. Then slightly
turn back the control BASS LEVEL, if required.
9) After operation, switch off the unit with the switch
POWER.
