1 029A Operating Manual Genelec 1029A Active Monitoring System GENELEC® GENELEC - |GENELEC” 1029A Active Monitoring System General description ‘The bi-ampliied GENELEC 10294 is a two ‘way active monitoring speaker designed tobe small but sil have high output, low coloration, and broad bandwiath ‘The 1029A is ideal for near field monitoring, mobile vans, broadeast and TV control rooms, surround sound systems, budget home studios, multimedia applications and also for use with computor soundcards. [As an active speaker, it contains drivers, power amplifiers, active crossover filers and protection cicultry. The Directly Control Waveguide™ (OCW) technology used provides excellent frequency balance in dificult acoustic environments. f necessary, the bass response of the 1029A's can be extended with @ Genolec 70508 or 7O60A subwooter. Integrated Construction ‘As the amplifiers are bull into the speaker ‘enclosure, the only connections requred ara the mains supply and the ine love input signal, aking the 1029A very easy to set up and use. The Integrated design allows the amples and the drivers to be calbrated as single unit at the factory This eliminates th ‘iets of component olerances and ensures consistent quay The cast aluminium cabinet has rounded comers and a haré-weating painted outer surace Drivers ‘The base frequencies are reproduced by a +190 mm (5°) base driver mounted in a 4.5 litre vented cabinet. The -3 dB point lies at 68 Hz and the frequency response extends own to 65 Hz (-6 <8), ‘The high trequency ceiver is a 19 mm (14°) metal dome. Uniform dispersion control Is achieved with the revolutionary OCW “Technology plonoered by Genelec, which has also resulted in perlect phase and delay uniformity atthe crossover frequency. Magnetic shielding is standard on the 1028A. Shielding is vital for applications ‘such as video post production, where stray magnetic fds must be minimized. Crossover ‘The active crossover network consists of two parallel bandpass fiters. Acoustical, the fl- tors are complementary and the slopes are ‘24-92 aBfoctave. Tho crossover frequency ig 83 kHz. The active crossover controls (*eoble tt, bass tt and bass ral-of) allow this speaker to be exacily matched to any application, Amplifiers ‘The ampitier unit fs bull into the speaker enclosure. The bass and treble ampiiirs both produce 40 W of output power. The fast low distortion amplifiers are capable of criv- ing a stereo pair o peak output sound pres ‘sure levels in excess of 110 dB at t m, The unit incorporates special circuitry for eriver ‘overload protection. Variable input sensitivity ‘tows for accurate level matching Installation Each 1029A monitors supplied with an inte grated amplifier unit, mains cable and an ‘operating manual. Ater unpacking, place the loudspeaker in its required listening postion, taking note of the tine of the listening axis (200 Figure 1). Before connecting up, ensure that the mains switch is off and the volume control fully counter-lockwise (see Figure 1) Check that the mains voltage selectors co: rectly eet (models sold in Europe havo a fixed 230V setting). Audio input is via @ 10 kOhm balanced XLR connector or @ 10 KOhm bal anced 1/4" Jack, An unbalanced source may bbe used as long as pin 3s grounded to pin 1 atthe input (see Figure 2).Once the connec- tion has been made, the speakers are ready to be switoned on. Setting the volume control. The input sensithity f the speakers can be matchod to the output ofthe mixing desk or ther source by adjusting the volume contol on the front pane! (see Figure 1), Setting the tone controls ‘The response of the system usually has to be adjusted to match the acoustic environment The adjustment is done by setting the tone contol switches on the rear panel. The tone contro has four switehas and can adiust ‘treble tit, bas tit’ and "bass roll-off? The factory settings for these are ‘ALL OFF" to vo @ flat anechoic response. See Table 1 for suggested tone control setings in lifer- ing acoustic environments. Figure 4 shows the effect of the controls on the anecholc response, Always start adjustment by seting ail suitches to ‘OFF position. Then set the ‘witch it needad to the ‘ON’ position to select the response curve needed. Monitor placement Console top mounting Whe 10294'8 are used for near field moni- toring, avold mounting them directly on the console top. Instead position the speakers slightly behind the console by using floor stands, wall mounts or microphone stands ‘This minimises the reflection trom the con- sale surface from colouring the sound. Room placement itis vital thatthe monitors are conecty posh tioned Inthe room as tis greatly affects their performance, To produce a true and accurate sloroo image the monitors must have exactly similar frequency responses, which is true in free field conditions. The frequeney charts shown are for tree field conditions. When placed in @ room the response changes due to rellactions af the wave from the room's boundaries. It is therefore necessary to place the monitors at the same height and aiso at the same distance from the front and side walls s0 that the reflections, and therefore the changes tothe frequency response, are the same ‘The distance from the front wal! should be fther lass than 1 m, or alternatively more than 3 m to avoid an uneven frequency response due to reflections from the wall IW the speaker is placed close to tho wall (€1 m) this will boost the lower frequencies ‘and the tone controls shouts then be adjusted ‘appropriately (see Tab 1) “The monitors should be slmed toward the listening position, This is due tothe effect ofGENELEC* Figure 1: 1020A's outer cimensions, wih Speaker Mounting Peston Treble Tit | Bass it | Bass Rol-Of Flat Anechoic Response - OFF OFF OFF Free standing iva damped rom oF | oF OFF Free standing in a reverberant room "OFF -20B OFF Near fed on console big or | aaa OFF Nearo a wall ofr | 60s OFF vn 70808 or 10014 suowontr | Samatove | See above | oy e 1: Suggested tone conto stings fo eifring acoustical ensronments Figure 2: Typo of cae nesses it Unbalanced source ls used example shown i RCA output to tho XLR inpus) the DOW which increases the dlrectiviy If ‘no ratio of rect sound to reflected sound is greater the listener is then able to listen to more of the material and less of the room effets.
