What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Genelec 1038A active monitors

 

MONITORS

The Genelec 1038A is a three-way active monitoring system including loudspeaker  drivers,  speaker enclosure, multiple power amplifiers  and  active,  low  signal level  crossovers.  Designed  for medium  sized  control  rooms  this system is ideal for project studios, film  and  video  post-production and  broadcast  monitoring.  CD mastering is also tailored for, where broad bandwidth, high SPL's and extended low frequency response are  essential.  The  1038A  is designed to perform well both as a free-standing monitor and flush mounted into the control room wall. The  unique  Directivity  Control Waveguide  (DCW)  Technology used  provides  excellent  stereo imaging  and  frequency  balance even in difficult acoustic environments. The fast, low distortion  amplifiers  are  capable of  driving  the  stereo  system  to peak  output  levels  in  excess  of 124 dB SPL at 2 m with program signals. Versatile crossover controls allow for precise matching of the speaker system to different acoustic  conditions.  The  system can be used both in vertical and horizontal  orientation  by  simply rotating the DCW unit.

AMPLIFIERS

The  bass,  midrange  and  treble amplifiers  each  produce  400W, 120W  and  120W,  respectively  of short  term  power  with  very  low THD  and  IM  distortion.  Special attention has been paid to electronic  design  to  ensure  the highest  subjective  sound  quality currently  possible.  The  system incorporates  special  circuitry  for drivers overload protection.

Thermal protection is also included for the amplifiers


DRIVERS

The bass frequencies are reproduced  by  a  385  mm  (15") bass  driver  loaded  with  a  110 liters vented box. The -3dB point is  33  Hz  and  the  low  frequency response extends down to 29 Hz (-6  dB). The  midrange  frequencies  are reproduced by a  proprietary 130 mm  (5")  direct  radiating  cone driver  loaded  with  a  DCW.  The high  frequency  driver  is  a  25mm (1") metal dome also loaded by a DCW. A factory-installed magnetic shielding  option  is  available  for applications where magnetic stray field must be minimized

Genelec 1031A active monitors

The Genelec 1031A is a two-way active monitor system, consisting of a vented enclosure with a multiple amplifier unit set into the back. The amplifier unit contains a low signal level active crossover, two power amplifiers and overload protection for each driver. This design provides high output, low coloration and broad bandwidth. The system's excellent dispersion and precise imaging together with its compact size make it ideal for near field monitoring, broadcast and TV control rooms, mobile vans, home studios and travelling engineers.

 



Genelec's unique Directivity Control Waveguide™ (DCW ™) Technology is used to provide excellent stereo imaging and frequency balance, even in difficult acoustic environments. This is enhanced by the versatile crossover controls, which allow the precise matching of the speaker system to its surroundings. It is capable of producing peak acoustic levels of over 120 dB SPL at 1m. The only connections to the system are the mains supply and the input signal, making it very easy to use.
