4. MIXER DESCRIPTION
4.1. Basic design concepts.
The AEQ BC-2500 Audio Mixer has been designed for use in radio broadcast studios
together with mobile units, television and sound installations where the quality and reliability of the
equipment are fundamental factors.
The criteria base for development and fabrication of the audio mixer were based on our extensive
experience in the field of radio broadcasting and direct contact with the professionals in the sector.
This has allowed us to capture the necessity of an audio mixer for radio and television in line with
current technology and with the highest performance.
The design and configuration assures rapid assimilation of the mixer functions by the user. The
logical distribution of the controls and the automatic monitor and signal cut features simplify the
operator tasks.
The modular concept allows the extraction of any module for repair or replacement in a
few moments. The high quality of the components used in manufacture guarantees the prolonged
service life of the equipment.
The AEQ BC 2500 audio mixer is user configurable according to the specific
requirements. Beginning with the standard ex-works configuration, it is easily upgraded by
incorporating new input modules or it can be redistributed according to operator preferences.
The following details some of the characteristics that make the AEQ BC 2500 mixer an
