Connecting Cords - HK Audio LINEAR SUB Serie Bedienungsanleitung

1 Gain Bass
This knob adjusts the subwoofer's volume. When set to the 12 o'clock
position (0 dB /center-notched), the subwoofer's volume is matched to the
LINEAR 5 active speakers' levels to achieve a balanced soundscape with an
evenhanded distribution of low and midrange frequencies. If you want to
increase or decrease the subwoofer's volume, simply rotate the knob to the
left or right (control range +/-6 dB).
2 Power LED
This LED lights up green when the Power button is set to On and mains
power is provided
3 Limit LED
This LED lights up red when the power amp's input signal is too high or a
fault has been detected. The LED briefl y fl ashes red to tell you the limiter is
responding to signal peaks.
Caution! If the Limit LED stays red while the unit is up and running, it
is being overloaded. Turn down the signal level! If you are not routing a
signal in and the Limit LED stays red, the system has detected a fault.
4 Confi guration
This switch optimizes the LINEAR active sub for deployment with other
LINEAR 5 series units.
Set the switch to this position to confi gure one LINEAR active sub for
use with one LINEAR 5 active speaker.
Set the switch to this position to operate two LINEAR active sub with
one LINEAR 5 active speaker. In this setting, the levels of the two Line Out
Mid/High outputs are boosted by up to 6 dB to bring up the one mid/ high
unit's level and balance it out with two LINEAR active subs.
5 X-Over Bass (L SUB 1200 A, L SUB 2000 A)
The X-Over switch lets you adjust the upper corner frequency of the X-over
built into the LINEAR active sub.
• L SUB 1200 A between 110 Hz and 130 Hz
• L SUB 2000 A between 100 Hz and 120 Hz
Your choice of setting will depend on the conditions in the venue and the
type of audio signal.
6 Mode (L SUB 4000 A)
The Mode switch lets you adjust the upper corner frequency of the X-over
built into the LINEAR active sub.
• L SUB 4000 A between 70 Hz (Sublow) and 100 Hz (Sub)
Your choice of setting will depend on the conditions in the venue and the
type of audio signal, as well as whether the subwoofer is being used as a
sub-low supplement or as a system bass.
7 Phase
The Phase switch confi gures the LINEAR active sub's phase position to
match that of the connected mid/ high units (0°/180°). Set the switch to 0°
when operating the bass bin with LINEAR 5 mid/ high units. You may have
to invert the phase 180° to operate it with other speakers.
8 Line Out Mid/High L/R
Use these two electronically balanced XLR outputs to connect active mid/
high units.
9 Input L/R
This electronically balanced, combination XLR/ 6.3 mm (1/4") input accepts
audio signals.
10 Thru L/R
This parallel output routes Input L/R's incoming signal back out.
11 Power
This is the on/off button for the LINEAR 5 active sub. Its status LED lights
up green when it is engaged.
12 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 fi x the mains cord in place to
prevent accidental disconnection.
13 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 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.
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
specifi ed on the LINEAR SUB. 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 Confi guration 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, eff ects, and so forth. LINEAR 5 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 5 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 fl ip the Power switch, the fan will briefl y start up (system
check) and stop after about fi ve 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.
