4030C

Operating Manual

General

The bi-amplied Genelec 4030C is an extremely

compact two way active loudspeaker designed

for xed installations. As an active loudspeaker, it

contains drivers, power ampliers, active crossover

filters and protection circuitry. The 4030C is

designed for indoor use only, in temperatures

between 15 to 35 degrees Celsius and relative

humidity between 20 % and 90 %.

The MDE™ (Minimum Diraction Enclosure™)

loudspeaker enclosure is made of die-cast

aluminium and shaped to reduce edge diraction.

Combined with the advanced Directivity Control

WaveguideTM (DCWTM), this design provides

excellent frequency balance in difficult acoustic

environments.

Positioning the loudspeaker

Each 4030C is supplied with an integrated amplier

unit, mains cable, a 3-pin balanced Euroblock

connector for audio signal, 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 o. The

power switch of the 4030C 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 unearthed mains supply or using an unearthed

mains cable. Audio input is via a 10 kOhm

balanced connector. The pin sequence of the

4030C

Active Loudspeaker

connector is shown in Figure 2.

Connect the signal cable to the 3-pole plug

provided with the loudspeaker and secure the

connections by tightening the screws on each

pole. Push the plug into the connector on the

loudspeaker.

If you want to daisy-chain multiple

loudspeakers, simply connect a second signal

cable to the plug and use it to route the signal to

the next loudspeaker (see Figure 4).

Never connect the 4030C to the loudspeaker

outputs of a power amplifier or an integrated

amplier or receiver.

Once the connections have been made, the

loudspeakers are ready to be switched on.

ISSTM Autostart

The automatic power saving function ISS (Intelligent

Signal Sensing) can be activated by setting the

“ISS” switch on the back panel to “ON.” Automatic

powering down to standby mode happens after a

certain time when playback has ended. The power

consumption in standby mode is typically less than

0.5 watts. Playback will automatically resume once

an input signal is detected from the source.

There is a slight delay in the automatic powering

up. If this is undesirable, the ISSTM function can be

disabled by setting the “ISS” switch on the back

panel to “OFF.” In this mode, the loudspeaker is

powered on and o using the power switch on the

back panel.

Level control

The input sensitivity of the loudspeaker can be

matched to the output of the signal source by

adjusting the level control on the rear panel.

Setting the tone controls

The frequency response of the Genelec

4030C can be adjusted to match the acoustic

environment by setting the tone control

switches on the rear panel. The controls are

“Treble Tilt”, “Bass Tilt” and “Bass Roll-O”. An

acoustic measuring system such as WinMLS

or comparable is recommended for analyzing

the eects of the adjustments, 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 eect of the controls on the anechoic

response.

Treble Tilt

The Treble Tilt control (switch 1) boosts the treble

response of the loudspeaker at frequencies above 5

kHz by +2 dB, which can be used for compensating

for the high frequency loss at long distance.

Bass Tilt

The Bass Tilt control oers 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.

Table 1: Suggested tone control settings for diering acoustical environments

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

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

“ON”).

Bass Roll-O

Bass Roll-O (switch 3) activates a -4 dB lter to

the lowest bass frequencies (55 Hz). This can be

used for compensating excessively heavy bass

reproduction typically caused by loudspeaker

placement near room boundaries.

The factory setting for all tone controls is

“OFF” to give a at anechoic response. Always

start adjustment by setting all switches to “OFF”

position. Measure or listen systematically through

the dierent combinations of settings to nd the

best frequency balance.

Mounting considerations

Align the loudspeakers correctly

Always place the loudspeakers so that their

acoustic axes (see gure 1) are aimed towards the

center of the listening area. Only vertical placement

is preferred, as it minimises acoustical cancellation

problems around the crossover frequency.

Minimise reections

Acoustic reflections from objects close to the

loudspeakers like walls, cabinets etc. can cause

unwanted colouration blurring of the sound

image. These can be minimised by placing the

loudspeaker clear of reective surfaces.

Minimum clearances

Sucient clearance for cooling of the amplier and

functioning of the reex 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

clearance of 3 centimeters (13/16”) behind, above

and on both sides of the loudspeaker. The space

adjacent to the amplier must either be ventilated

or sufficiently large to dissipate heat so that the

ambient temperature does not rise above 35

degrees Celsius (95°F)

Mounting options

The Genelec 4030C oers several mounting

options: 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

Maintenance

No user serviceable parts are to be found within

the amplier unit. Any maintenance or repair of the

4030C unit should only be undertaken by qualied

service personnel.

Safety considerations

Although the 4030C has been designed in

accordance with international safety standards,

the following warnings and cautions should be

observed to ensure safe operation and to maintain

the loudspeaker under safe operating conditions:

• Servicing and adjustment must only be

performed by qualified service personnel.

The loudspeaker must not be opened.

• Do not use this product with an unearthed

mains cable or an unearthed mains

connection as this may compromise

electrical safety.

• Do not expose the loudspeaker to water or

moisture. Do not place any objects lled with

liquid, such as vases on the loudspeaker or

near it.

• This loudspeaker is capable of producing

sound pressure levels in excess of 85 dB,

which may cause permanent hearing

damage.

• Free flow of air behind the loudspeaker is

necessary to maintain sufficient cooling.

Do not obstruct airflow around the
