Fig. 2.1: Control elements and connections
(1) Power is supplied via an IEC connector. The matching cable is provided with
the unit.
(2) Use the POWER switch to turn on the B1220DSP. 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.
(3) Use the LEVEL control to adjust the signal gain of the MIC/LINE inputs.
Beforeyou 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 (4) 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,
thecontrol 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.
(4) The CLIP LED lights up when the input signal level is too high. In this case,
turn the LEVEL control (3) to the left until the LED goes out or only lights up
at peak levels.
(5) Use the MIC/LINE inputs (XLR connectors) for connecting audio signals.
(6) 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)
