10 Power
This is the on/off button for the LINEAR 5 active sub. Its status LED
lights up green when it is engaged.
11 Mains
Use the factory-included mains cord to connect this socket to a wall
outlet.
Note: All LINEAR 5 active subs are equipped with V-Lock mains
sockets. If you use a VOLEX locking mains cord or another optionally
available brand with the same design, you can fix the mains cord in
place to prevent accidental disconnection.
12 Speaker Out (L SUB 1200 A only)
This port serves to connect a passive L SUB 1200.
Heads up: Do not connect any other device. If you do, it may be
destroyed along with L SUB 1200 A.
2.2 Connecting Cords
Use a microphone cord equipped with XLR connectors or 6.3 mm (1/4”)
jack plugs to send the signal from the audio source (master, monitor,
line, or a similar output) to the balanced L/R Inputs. Connect the active
mid/ high units to the XLR outputs labeled Line Out Mid/High. Use the
two Thru L/R ports to route the fullrange signal to other speakers.
2.3 Operating the Sub
• Ensure the LINEAR 5 active sub’s Power switch is set to off.
Caution! Always make sure the local mains voltage matches the
voltage specified on the LINEAR 5 active subwoofer. You may destroy
its electronic components if you connect it to the wrong mains
voltage.
• Turn the Gain Bass knob to the 12 o’clock position (0 dB/ center-
notched).
• Set the Configuration switch accordingly to match the number of
LINEAR active subs you are using.
• Ensure all connected line sources are switched on before powering up.
First, switch on the connected mixer and all signal sources connected
to it, for example, keyboards, amps, effects, and so forth. LINEAR
active speakers should always be connected to the Line Out Mid/High
ports and switched on after all other components are up and running.
When you’re ready to tear the rig down, please turn the LINEAR active
speaker down by rotating the Input A/B Gain knobs counterclockwise
as far as they will go and switch them off before powering down all
other connected devices.
• When you flip the Power switch, the fan will briefly start up (system
check) and stop after about five seconds. The fan is temperature-
controlled. It kicks on only at very high volume levels and runs
according to the given temperature. The Status LED lights up red
during the system check and will extinguish unless a fault is detected.
• The Power LED will light up green if the unit is getting mains voltage
after the Power switch has been engaged.
2.4 Settings
• Adjusting Volume Levels with the Gain Bass Knob
Use the Gain Bass knob to adjust the active subwoofer’s volume to
suit the venue and situation. If you want to increase or decrease the
subwoofer’s volume, simply turn this knob to the left or right (control
range +/-6 dB). If you hear distortion or the signal sounds saturated,
first check the signal sources and, if possible, reduce the output signal
level there.
• Adjusting the Corner Frequency with the X-Over Bass
Switch
You can use this switch to adjust the LINEAR active sub’s frequency
range to match the signal you wish to render and/or the surroundings.
The Line Out Mid/High Left/Right outputs are not affected by this
setting.
• Adjusting the Phase Position with the Phase Switch
You can use the Phase switch to adjust the LINEAR active sub’s phase
position to match that of the connected mid/ high unit. Always set this
switch to 0° when operating the bass bin with LINEAR 5 mid/ high
units. You may have to invert the phase to operate this sub with other
speakers. If so, set the switch to 180°.
