Genelec 1030A Monitoring Speaker Operating Manual 1. General description Speaker Mounting Position System The bi-amplified GENELEC 1030A is a two way active monitoring speaker designed to be small but still have high output, low coloration and broad bandwidth. It shares many design features with the famous 1031A near field monitor. Due to its compact size, integrated construction, excellent dispersion and precise stereo imaging, this speaker system is ideal for Near Field monitoring, mobile vans, broadcast and TV control rooms, surround sound systems and budget and home studios. Designed as an active speaker, this unit 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.

The fast, low distortion amplifiers are capable of driving a stereo pair to peak output sound pressure levels in excess of 115 dB at 1 m. The unit incorporates special circuitry for driver overload protection. Variable input sensitivity allows for accurate level matching to the mixing console. Drivers The bass frequencies are reproduced by a 170 mm (6 1/2") bass driver loaded in a 6.5 liter 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 control is achieved with the revolutionary DCW Technology pioneered by Genelec, which has also resulted in perfect phase and delay uniformity at the crossover frequency. Both drivers are magnetically shielded. 2. Installation Each 1030A monitor is supplied with an integrated amplifier unit, a mains cable and an operating manual. After unpacking, place the loudspeaker in its required listening position, taking note of the line of the listening axis (see figure 2). Before connecting up, ensure that the mains switch is off (see figure 4) and the mains voltage selector is correctly set. Audio input is via a 10 kOhm balanced 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 desk, or other source, by adjusting the input sensitivity control on the rear panel (see figure 4). A small screwdriver is needed for the adjustment. The manufacturer's default setting for this control is -6 dBu (fully clockwise) which gives an SPL of 100 dB @1m with -6 dBu input level. 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 application. Setting tone controls The response of the system may also have to be adjusted to match the acoustic environment. The adjustment is done by setting the three tone control switches 'treble tilt', 'bass tilt' and 'bass roll-off' on the rear panel of the amplifier. The manufacturer's settings for these controls are 'All Off' to give a flat anechoic response. See Figure 1 for suggested tone control settings in differing acoustic environments. Figure 5 shows the effect of the controls on the anechoic response. Always start adjustment by setting all switches to 'OFF' position. Then set only one switch to the ON position to select the response curve needed. If more than one switch is set to 'ON' (within one switch group) the attenuation value is not accurate. Amplifiers The amplifier unit is mounted to the rear of the speaker enclosure on quick release vibration isolators, to ensure rattle free operation and long term reliability. The bass and treble amplifier produce 80 W and 50 W of short term Figure 2. Speaker acoustic axis and dimensions in horizontal and vertical mounting positions. WARNING! This equipment is capable of producing sound pressure levels in excess of 85 dB, which may cause permanent hearing damage. 5. Accessories Order code 1030-409 1030-404-V/H* 1030-405-V/H* Figure 3 . XLR connection if unbalanced input is required. Protective grille Wall mount Floor stand Vertical / horizontal mounting The speakers are normally delivered set up for vertical mounting. If horizontal mounting is needed the DCW plate may be rotated so that the GENELEC logo is located at the bottom left corner of the DCW. Remove the four corner screws of the DCW (use a Torx 20 screw driver) and pull the plate carefully out without stressing the wires or the gasket. Rotate the plate 90 degrees in the appropriate direction and remount the screws. Note that to get a mirror image pair, the DCWs must be rotated in different directions for the left and right speakers. When used in the horizontal position, the bass drivers should be on the inside to provide better low frequency summing. warnings and cautions must be observed: *State the desired speaker orientation V=vertical or H=horizontal when ordering these accessories. · Servicing and adjustment must only be performed by qualified service personnel. The amplifier's rear panel must not be opened, except by persons who are aware of the hazards involved. 6. Guarantee This product is supplied with a one year guarantee against manufacturing faults or defects that might alter the performance of the 1030A unit. Refer to supplier for full sales and guarantee terms. · · Do not use this product with an unearthed mains cable as this may lead to personal injury. Console top mounting If the 1030A's are used for console top monitoring, avoid mounting the speakers directly on the console. Instead position the speakers slightly behind the console by using floor stands or wall mounts. This prevents the reflection from the console surface from coloring the sound. 3. Maintenance No user serviceable parts are to be found within the amplifier unit. Any maintenance or repair of the 1030A unit should only be undertaken by qualified service personnel. 4. Safety Considerations Although the 1030A has been designed in accordance with international safety standards, to ensure safe operation and to maintain the instrument under safe operating conditions, the following Figure 4.
