SOUND REINFORCEMENT BASICS
Avoiding feedback
Feedback (the shriek sometimes emitted by PA systems) occurs
when the microphone (or pickup) and speaker are positioned too
close together for a given level of volume. Once feed back occurs,
it will continue until either the volume is decreased or the
microphone or speaker is moved. Gain is the degree to which the
volume may be turned up before feedback begins. In setting up a
sound system, the objective is to maximize gain.
Monitor Placement
HOT SPOT Monitors should be positioned within arm's
reach of the performer.
Monitors should be placed to the rear of the
microphone being used by the performer.
Avoiding Distortion
Distortion in a monitor system usually occurs when the amplifier is
being overdriven-nearing the limits of its power output capability.
Overdriving the amplifier may be corrected by reducing the bass
frequencies in the monitor mix (low notes use a lot of power).
Since the HOT SPOT NEOLITE driver will not reproduce tones
lower than 200 Hz, reduce the low frequencies if the speaker
begins to distort. Distortion may also originate with a bad signal
source.
NEO DRIVER
Introduced in 2004, the NEOLITE driver is a state of the art
controlled bandwidth speaker that is included in all products
covered in this manual with the exception of the MSPA. Tailored to
reproduce a frequency range from 150 Hz-18 kHz, the NEOLITE is
manufactured with the rare earth element Neodymium that has an
extremely intense magnetic field in comparison to its weight. This
magnetic field is also very concentrated, allowing the speaker to be
placed near sensitive equipment that may be affected by a strong
magnetic force, such as a TV or a computer monitor.
