Use the MIC/LINE inputs (XLR connectors) for connecting
audio signals.
The LINE OUT XLR jack provides the signal with no
additional gain applied in order to connect another
loudspeaker, for example. The output signal is a mix of
both input signals. (See Chapter 4.2 for more information
on how to use several loudspeakers)
The B415DSP is equipped with a 2-band tone control. Each
band allows you to apply a maximum boost/cut of 15 dB, in its
center position the equalizer is set to neutral.
Use the EQ HIGH control to cut or boost the treble range
by 15 dB. The cut-off frequency is 12 kHz.
Use the EQ LOW control to cut or boost the bass range by
15 dB. The cut-off frequency is 100 Hz.
The B415DSP features a high-pass filter with a slope of
24 dB/oct. to eliminate unwanted low-frequency content,
such as pop sounds produced by hand-held microphones,
or rumble or wind noise when using high-sensitivity
microphones. The LOW CUT control adjusts the cut-off
frequency. If you want to use the B415DSP in combination
with a subwoofer, you can use the high-pass filter to
lower the bass range reproduced by the subwoofer. This
allows you to operate the B415DSP even without an
external frequency crossover. Set the cut-off frequency
to the highest frequency that can be reproduced by the
subwoofer.
The CONTOUR switch governs the dynamic contour filter:
SPEECH
Setting the CONTOUR switch to SPEECH (switch not
pressed) will optimize the frequency response for speech
applications. This will raise the midrange, which in turn
ensures better intelligibility.
MUSIC
Setting the CONTOUR switch to MUSIC (switch pressed)
will optimize the frequency response for music playback.
Power is supplied via an IEC connector. The matching
cable is provided with the unit.
Use the POWER switch to turn on the B415DSP. Before
connecting the unit to the power mains, ensure that the
POWER switch is in OFF position.

Attention: The POWER switch does not fully
disconnect the unit from the mains. To disconnect
the unit from the mains, pull out the main cable plug
or appliance coupler. When installing the product,
ensure the plug or appliance coupler is readily
operable. Unplug the power cord completely when
the unit is not used for long periods of time.
Use the LEVEL control to adjust the signal gain of the
MIC/LINE inputs. Before you connect or disconnect a signal
source to or from one of the inputs, please turn the
corresponding control fully to the left. Once the signal source
is connected, increase the volume as desired by turning the
control clockwise. Always make sure that the CLIP LED
does not light up at all or with signal peaks only.
Line-level signals:
Devices with high output levels (e.g. the outputs of mixing
consoles or CD players) only need little gain. In this case,
the LEVEL control will mostly be positioned somewhere in
the area marked “LINE” (left half of the control range).
Microphone signals
Low-level microphone signals need more gain. When
microphones are used, the control will be positioned in the
MIC area (right half of the control range).
+
We would like to draw your attention to the fact that
extremely loud sound levels may damage your
hearing as well as your headphones/loudspeakers.
Turn the LEVEL control fully to the left before you
switch on the unit. Be careful to select a suitable
volume at all times.
The CLIP LED lights up when the input signal level is too
high. In this case, turn the LEVEL control to the left
until the LED goes out or only lights up at peak levels.
