BNO Acoustics BP-40: Passive Crossover

Uses no active components (transistors, IC's, tubes) and needs no power supply (AC, DC, battery) to operate. The crossover in a typical loudspeaker is of the passive variety. Passive crossovers consist of capacitors, inductors and resistors.

Sampling Synchronization
Signal Synchronization pulses that are generated by a digital audio tape recorder, are recorded onto the tape and then used as a clock signal to time the sampling of the sampling circuits.

BNO Acoustics YM-44: FOH (Front of House)
Refers to the speakers that face toward the audience. Also called the "main" speakers.

BNO Acoustics GT-60: Formant
An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.

Returns
Short for the term Echo Return or Auxiliary Return (the input of the console which brings back the effects signal from the echo chamber or other reverberation effects device).

Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.

Consumer Format (Consumer DIF)
A standard adopted by IEC for sending and receiving digital audio based on The AES Professional Interface.
