General

The bi-amplified Genelec 4030B is an extremely

compact two way active loudspeaker designed for

fixed installations. As an active loudspeaker, it con-

tains drivers, power amplifiers, active crossover fil-

ters and protection circuitry. The 4030B is designed

for indoor use only, in temperatures between 15 to

35 degrees Celsius and relative humidity between

20 % and 90 %.

The MDE™ (Minimum Diffraction Enclosure™)

loudspeaker enclosure is made of die-cast alu-

minium and shaped to reduce edge diffraction.

Combined with the advanced Directivity Control

WaveguideTM (DCWTM), this design provides excel-

lent frequency balance in difficult acoustic environ-

ments.

Positioning the loudspeaker

Each 4030B is supplied with an integrated amplifier

unit, mains cable, a 5-pin connector for audio signal

and 12 V trigger voltage, a keyhole type wallmount

and an operating manual. After unpacking, place the

loudspeaker in its required listening position, taking

note of the line of the acoustic axis. The axis should

be pointed towards the center of the listening area.

Connections

Before connecting up, ensure that the loudspeakers

and the signal source have been switched off. The

power switch of the 4030B is located on the back

panel (see Figure 3). Connect the loudspeaker to an

earthed mains connection with the supplied mains

cable. Never connect the loudspeaker to an un-

earthed mains supply or using an unearthed mains

cable. Audio input is via a 10 kOhm balanced con-

nector. The connector also has two pins for 12 V

trigger voltage for power switching. The current fed

into the 12 V trigger connection must not exceed

200 mA. The pin sequence of the connector is

shown in Figure 2.

Connect the signal cable and 12 V trigger volt-

age to the 5-pole plug provided with the loud-

speaker and secure the connections by tightening

the screws on each pole. Push the plug into the

connector on the loudspeaker.

Never connect the 4030B to the loudspeaker

outputs of a power amplifier or an integrated am-

plifier or receiver.

Once the connections have been made, the

loudspeakers are ready to be switched on.

Autostart And Remote Control

The 4030B is equipped with an Autostart function,

which automatically turns the amplifier to Standby

mode if an input signal has not been detected for

approximately 1 hour.

The amplifier mode can also be switched by a

12 V DC trigger type remote control. The remote

control wires can be connected to the first two

(starting from left) poles of the Phoenix connec-

tor (See Figure 2 for the connector pin sequence).

Remote control overrides the Autostart function.

Level control

The input sensitivity of the loudspeaker can be

matched to the output of the signal source by ad-

justing the level control on the rear panel.

Setting the tone controls

The frequency response of the Genelec 4030B

can be adjusted to match the acoustic environ-

ment by setting the tone control switches on the

rear panel. The controls are “Treble Tilt”, “Bass

Tilt” and “Bass Roll-Off”. An acoustic measuring

system such as WinMLS or comparable is recom-

mended for analyzing the effects of the adjust-

ments, however, careful listening with suitable

test recordings can also lead to good results if a

test system is not available. Table 1 shows some

examples of typical settings in various situations.

Figure 4 shows the effect of the controls on the

anechoic response.

Treble Tilt

The Treble Tilt control (switch 1) attenuates the treble

response of the loudspeaker at frequencies above

5 kHz by 2 dB, which can be used for smoothening

down an excessively bright sounding system.

Bass Tilt

The Bass Tilt control offers three attenuation levels

for the bass response of the loudspeaker below

2 kHz, usually necessary when the loudspeakers

are placed near a wall or other room boundaries.

The attenuation levels are -2 dB (switch 3 “ON”),

-4 dB (switch 4 “ON”) and -6 dB (both switches

“ON”).

Bass Roll-Off

The Bass Roll-Off (switch 2) activates high-pass

filtering at 85 Hz to match the low frequency cutoff

of the 4030B to subwoofers using 85 Hz low-pass

filtering.

The factory setting for all tone controls is “OFF”

to give a flat anechoic response. Always start ad-

justment by setting all switches to “OFF” position.

Measure or listen systematically through the dif-

ferent combinations of settings to find the best fre-

quency balance.

Mounting considerations

Align the loudspeakers correctly

Always place the loudspeakers so that their acous-

tic axes (see figure 1) are aimed towards the center

of the listening area. Only vertical placement is pre-

ferred, as it minimises acoustical cancellation prob-

lems around the crossover frequency.

Minimise reflections

Acoustic reflections from objects close to the

loudspeakers like walls, cabinets etc. can cause

unwanted colouration blurring of the sound im-

age. These can be minimised by placing the loud-

speaker clear of reflective surfaces.

Minimum clearances

Sufficient clearance for cooling of the amplifier and

functioning of the reflex port must be ensured if the

loudspeaker is installed in a restricted space such

as a cabinet or integrated into a wall structure. The

surroundings of the loudspeaker must always be

open to the listening room with a minimum clear-

ance of 3 centimeters (13/16”) behind, above and on

both sides of the loudspeaker. The space adjacent to

the amplifier must either be ventilated or sufficiently

large to dissipate heat so that the ambient tempera-

ture does not rise above 35 degrees Celsius (95°F)

Mounting options

The Genelec 4030B offers several mounting op-

tions: On the base of the loudspeaker is a 3/8”

UNC threaded hole compatible with a standard

microphone stand. On the rear there are two

M6x10 mm threaded holes for Omnimount® size

20.5 brackets or the keyhole wall mount adapter

provided with the loudspeaker. See Genelec Ac-

cessories Catalogue on www.genelec.com for a

complete list of mounting hardware options.

Maintenance

No user serviceable parts are to be found within

the amplifier unit. Any maintenance or repair of the

4030B unit should only be undertaken by qualified

service personnel.
