Genelec 1030A Monitoring Speaker

System

The bi-amplified GENELEC 1030A is a two way active monitoring speaker designed to produce high SPL output, low coloration and broad bandwidth in a small cabinet size. The 1030A is ideal for applications where space is at premium such as Near Field monitoring, mobile vans, broadcast and TV control rooms, surround sound systems and budget and home studios. Designed as an active speaker, the 1030A contains drivers, power amplifiers, active crossover filters and protection circuitry. The Directivity Control Waveguide™ (DCW™) technology used provides excellent frequency balance even in difficult acoustic environments.

Drivers

The low frequencies are reproduced by a 170 mm (6 1/2”) bass driver loaded in a 6.5 liters vented cabinet. The -3 dB point lies at 52 Hz and the frequency response extends down to 47 Hz (-6 dB).

The high frequency driver is a 19 mm (3/4”) metal dome. Uniform dispersion con- trol is achieved with the innovative DCW Technology pioneered by Genelec, which also provides perfect phase and delay uni- formity at the crossover frequency.

Both drivers are magnetically shielded.

Crossover

The active crossover network consists of two parallel bandpass filters. Acoustically, the filters are complementary and the slopes are 24 - 32 dB/octave. The crossover frequency is 3.5 kHz. The active crossover controls (‘treble tilt’, ‘bass tilt’ and ‘bass roll-off’) allow this speaker to be exactly matched to any room environment.

Amplifiers

The amplifier unit is mounted to the rear of the speaker enclosure on quick release vibra- tion isolators, to ensure rattle free operation and long term reliability. The bass and treble amplifier produce respectively 80 W and 50 W of short term power. The peak output sound pressure level of the 1030A exceeds 115 dB at 1 m. The unit incorporates special circuitry for driver overload protection. Vari- able input sensitivity allows for accurate level matching to console output section.

Installation

Each 1030A monitor is supplied with a mains cable and an operating manual. After unpacking, place the speaker so that its acoustical axis (see figure 2) is aimed towards the listening position. Do not place the speaker in a horizontal position as this

may cause acoustical cancellation problems around the crossover frequency.

Sufficient cooling for the amplifier must be ensured if the speaker is installed in a restricted space such as a cabinet or inte- grated into a wall structure. The minimum clearance for the amplifier is 10 centimeters (4") to any object. The space adjacent to the amplifier must either be ventilated or suf- ficiently large to dissipate heat so that the ambient temperature does not rise above 35 degrees Celsius (95°F).

Before connecting up, ensure that the mains switch is off (see figure 4). Check that the mains voltage selector is correctly set (Models sold in Europe have a fixed 230 V setting). Audio input is via a 10 kOhm bal- anced XLR connector, but unbalanced leads may be used as long as pin 3 is grounded to pin 1 of the XLR (see figure 3). Once the connection has been made, the speakers are ready to be switched on.

Setting the input sensitivity

The input sensitivity of the speakers can be matched to the output of the mixing console, or other source, by adjusting the input sensi- tivity control on the rear panel (see figure 4). A small screwdriver is needed for the adjust- ment. The manufacturer’s default setting for this control is -6 dBu (fully clockwise) which
