TRUTH B2030A/B2031A
Control elements4
Control elements2.
The control elements described in the following are the same on
both loudspeakers.
Front panel display elements (here: B2030A)Fig. 2.1:
ON - This LED lights up as soon as you switch on the {1}
speaker.
LIMIT - Lights up as soon as one of the built-in protections {2}
is activated.
Rear panel connectorsFig. 2.2:
All connectors of the TRUTH face downwards, so as to allow you
to place the speaker as closely to a wall as possible.
INPUT - These are the balanced inputs of your TRUTH, laid {3}
out as 1/4" TRS and XLR connectors.
The mains connection is achieved via the standard IEC {4}
connector. A matching power cord is included.
FUSE COMPARTMENT/VOLTAGE SELECTION - Before {5}
plugging the unit into a power socket, please make sure
you have selected the correct voltage. Faulty fuses must be
replaced with fuses of appropriate rating without exception.
Some units feature a fuse compartment that can be oper-
ated in two different positions, allowing alternating between
230 V and 120 V.
When using the unit outside of Europe (running on +
120 V), you have to implement a fuse with a higher
rating.
The POWER switchFig. 2.3:
Use the POWER switch to power up your TRUTH. The {6}
POWER switch should always be in the "Off" position when
you are about to connect your unit to the mains.
Caution
The POWER switch does not fully disconnect the unit +
from the mains. Unplug the power cord completely when
the unit is not used for prolonged periods of time.
The TRUTH should be the last device in the signal chain +
to be switched on and the rst to be switched off. This
way, loud switch-on "thumps" that can occur when pow-
ering other equipment on or off can be avoided.
INPUT TRIM controlFig. 2.4:
INPUT TRIM - Use this control to adapt the TRUTH’s input {7}
sensitivity to the signal source.
Rear panel control elementsFig. 2.5:
LOW FREQUENCY - With this switch you can adapt the {8}
woofer to a subwoofer system or emulate the sound char-
acteristics of small speaker systems.
ROOM COMPENSATION - For maximum exibility the {9}
TRUTH features a switch that adjusts the speaker depend-
ing on its setup position.
HIGH FREQUENCY - This switch adapts the speaker's [10]
frequency response to the damping characteristics of the
control room.
Rear panel control elementsFig. 2.6:
The following control elements are found only on the B2031A:
POWER MODE - This switch allows you to toggle between [11]
"ON", "OFF" and "AUTO" power-up modes (see chapter
3.1).
MUTE LOW - Disables the woofer for servicing and main-[12]
tenance.
MUTE HIGH - Disables the tweeter for servicing and main-[13]
tenance.
