1.3 Control elements
Fig. 1.1: Rear panel control and connecting elements of the B300

The
OVL
LED (= overload) lights up as soon as any one of the built-in protections has been activated.
For improved control a second overload LED is installed on the front panel of the speaker cabinet.
2
The
LINE
LED lights up when the input sensitivity of the B300 has been set to LINE level with switch
.
When you have a mixing console or any other playback device (e.g. CD player) connected,
be sure to set this switch always to LINE level!

The
VOLUME
control governs the overall volume level of your B300.

The
INPUT
switch changes the input sensitivity from line to microphone level, and vice versa.

The
MIC
LED lights up when the input sensitivity of the B300 is set to microphone level.

Use the
HI
control to adjust the high-frequency range of the built-in equalizer.
7
Use the
LO
control to adjust the low-frequency range of the built-in equalizer.

This stereo 1/4" TRS connector is the input for the signal source. You can also connect a microphone
(

must be set to MIC!
)

This XLR connector is a balanced input for the signal source. You can also connect a microphone
(
in this case, switch
must be set to MIC!
)
10
The
LINK OUTPUT
is directly connected to the inputs of the B300 and provides a one-to-one copy of the
input signal, for example, to loop the signal through to the input of another device (e.g. a second B300).
11
Use the
POWER
switch to put the B300 into operation.
12
FUSE HOLDER/VOLTAGE SELECTOR
and
MAINS CONNECTOR
. Please make sure that your local
voltage matches the voltage indicated on the unit, before you attempt to connect and operate the
B300. Blown fuses may only be replaced by fuses of the same type and rating. Some models allow for
inserting the fuse holder in two different positions, in order to switch over from 230 V to 115 V operation,
and vice versa (see chapter 1.2.1). Please note that for 115 V operation outside Europe, you need a fuse
of a higher rating.
