Signal / Limit
This dual-color LED remains off until the unit gets a signal. It lights up
green to indicate incoming signals and red to indicate signal peaks. The LED
briefl y fl ashes red to tell you the limiter is responding to signal peaks.
Caution! If the Status LED stays red during operation, the cabinet is being
overloaded. Turn down the signal level! If you are not routing a signal in
and the Status LED stays red, the system has detected a fault.

Bass Boost/Flat (LF) switch
This DSP-driven EQ optimizes the frequency response for the given
application.
Setting this switch to „Bass Boost" pumps up the bass. This boosts a
broad band of bass frequencies in the range between 60 Hz and 100 Hz and
extends the low-end response.
L3 112 FA / L3 115 FA:
To use the speaker as a top unit combined with
a subwoofer, set this switch to „Flat (LF)". This ensures the frequency
response remains linear all the way down to the cutoff frequency for
optimum subwoofer coupling and a homogenous overall sound.
L3 112 XA:
To voice the L3 112 XA with a more assertive signal for use as
a stage monitors, set this switch to „Flat (LF)". This also optimizes the
speaker's frequency response for use with subwoofers.

Flat (HMF)/Contour switch
This DSP-driven EQ optimizes the frequency response for the given
application.
Setting this switch to „Flat (HMF)" conjures the optimum linear frequency
response for live performances and for operation in combination with
subwoofers.
Setting this switch to „Contour" dampens a broad band of midrange
frequencies centered at 3.5 kHz by as much as -6 dB. This takes the
edge off the sonic image to prevent and mitigate early listening fatigue,
particularly at short distances where audience members are close to the
speaker. The overall volume is not aff ected.

2 Connecting Cords
• If you wish to use a LINEAR 3 unit as a standalone speaker or as a stage
• Plug a cord equipped with an XLR connector into the Thru A port to patch
• If you wish to combine a LINEAR 3 speaker with a LINEAR SUB series
Go to page 32–35 for illustrations of cable connections.
3 Operating the Cabinet
• Ensure the LINEAR 3 cabinet is switched off .
Caution! Always make sure the local mains voltage matches the voltage
specifi ed on the LINEAR 3 unit. You may destroy powered cabinet's
electronic components if you connect it to the wrong mains voltage.
• When patching in line signals, ensure all other connected components
• When you fl ip on the Power switch, the fan will start up briefl y for a
monitor (L3 112 XA) without a subwoofer, connect your mixer's monitor
out, line out, or a similar output to Input A using a balanced cord equipped
with XLR or 1/4" (6.3 mm) connectors.

to route all incoming signals through, use the Thru B port and set the Out

are switched on before powering up. The connected mixer as well as all
signal sources connected to it—keyboards, instrument amps, eff ects and
the like—should be switched on fi rst. Always switch on the LINEAR 3 last,
after you power up all connected devices, and switch it off fi rst; that is,
before you switch off all connected devices.
system check and switch off after around fi ve seconds. After that, the
cabinet's circuitry controls the fan. It kicks in only at very high volume
levels and is regulated according to the temperature. The Status LED
lights up red during the system check. It will turn green if there is no error
and the system is getting mains power.
