Pulsar 1.1

12 Stand Alone / System/Monitor
This switch activates an EQ filter that voices the powered
PULSAR speaker‘s frequency response to suit the given
application. Set it to System Monitor when you want to
use it in combination with a subwoofer or separately as a
stage monitor. Setting the switch to Stand Alone extends the bass range
to configure the PULSAR speaker‘s frequency response for use as a
standalone, fullrange cabinet.
13 Flat / Contour
Setting this switch to Flat activates an EQ filter that
conjures a linear frequency response, which is perfect
for live performances. The Contour voicing takes the
edge of the midrange frequencies to better throw highly
compressed, mids-heavy signals over short distances.
1.2 Connecting Cords
Use a microphone cord equipped with XLR connectors or 1/4” (6.3 mm)
jack plugs to send the signal from the audio source (monitor, line, or a
similar output) to the balanced Inputs A and B, or connect two cords
with RCA plugs to Inputs C. If you wish to connect a microphone
directly to the powered PULSAR cabinet without going into a mixer first,
plug it into the balanced Input A and set the Mic/ Line switch to Mic.
Also use a balanced XLR/ 1/4” (6.3 mm) microphone cord to do this.
1.3 Operating the Speaker
• Ensure the PULSAR speaker’s Power button is set to Off.
Caution! Always make sure the local mains voltage matches
the voltage specified on the unit. You may destroy the powered
speaker‘s electronic components if you connect it to the wrong
mains voltage.
• Turn Gain knobs A, B and C all the way down, rotating them
counterclockwise as far as they will go.
• 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. Then make
sure the powered PULSAR speaker‘s Mic/Line button is set correctly
(standard = Line). Always switch the powered PULSAR speaker on
last; that is, after you switch on all connected devices, and always
switch it off first; that is, before you switch off all connected devices.
• When you press the Power button, 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 and load. The Status LED lights up
red during the system check, and then green if there is no malfunction
and the unit is getting mains power.
1.4 Settings
Adjusting volume levels with the gain knobs
Turn these knobs and press the Mic/Line button (Input A only) to adjust
the level of incoming line and microphone signals. If you hear distortion
or the signal sounds saturated, first check the signal sources and, if
possible, reduce the output signal level there.
Turn the Gain knobs to the 12 o’clock position (0 dB /center-notched).
This is the preferred setting if you are using a mixing console to
address the powered PULSAR speaker. Twist the Gain knob clockwise
if you have connected a CD player or a keyboard directly to the unit.
Depending on the input signal level, you may want to turn it all the way
to the far right to achieve maximum volume. Use Input C to connect
portable music players directly to PULSAR mid/ high units.
Filter settings
Use the PULSAR mid/ high units‘ Stand Alone/ System Monitor and
Flat/ Contour switches to choose the filters for the given application or
to suit your preferences (see section 1.1).
1.5 Alignment
HK Audio DuoTilt™ 3/7 (PL 110 FA / PL 112 FA /
PL 115 FA)
The HK Audio DuoTilt™ 3/7 aims powered PULSAR speakers up and
down to prevent or minimize troublesome ceiling reflections. The front
aperture of the HK Audio DuoTilt™ inclines the cabinet 3°, and the rear
opening tilts it 7°.
Select the 7° option when setting powered PULSAR speakers on fully
extended tripods or mounting poles. This angle gets the job done when
you want to address fewer listeners standing very near the speakers.
If you want to address an audience at a greater distance from the
speakers, opt for the 3° angle on the DuoTilt™.
