1. Equalizer adjustment method:
Subwoofer 20Hz-40Hz, appropriate, powerful sound. Able to control thunder, bass
drum, organ and bass sounds. Will enhance the music becomes too turbid.
Bass 40Hz-150Hz, a sound basis for part of its energy accounts for 70% of the
audio energy is the important component of the performance of musical styles.
Appropriate, proper relaxation bass, voice full soft, low voice thin, 150Hz, over time
will enhance the sound of nausea, decreased brightness, increased nasal.
Bass 150Hz-500Hz, a sound structural elements, the human voice in this position,
less than, the concert will be music drowned the sound,sound soft and weak,very
vigorous when appropriate to enhance effective and improve the sound intensity and
loudness. Will increase when the bass becomes too stiff, 300Hz at the excessive
increase 3-6dB, if coupled with reverb, would severely affect the clarity of the sound.
Alto 500Hz-2KHz,contains most of the instruments of the low-order harmonics and
overtones,is a snare drum and percussion sound characteristics. Appropriate, thorough
sound bright, low sound dim. Improve over the phone when you have a similar sound.
Alt: 2KHz-5KHz, the strings, and the characteristics of sound (pull string in the bow and
the string sound of the friction and shoving, playing the pull string music the sound of a
finger).Insufficient penetration of the sound down, too strong language when
masking syllable recognition.
Treble: 7KHz-8KHz,is the layering of sound frequency.Excessive increase will piccolo,
flute,prominent voices, the language and tone scared increase dental
High tone 8KHz-10KHz
When appropriate,triangle and fork set high permeability of the metal sense, the rhythm
of the sand clock clearly visible.Excessive sound will not improve the natural, easy to
burn high-frequency unit.
2.Should be balanced sweet sound
150Hz or less (bass) should be plump, soft and elastic
150Hz-50Hz (bass) should be deep and powerful are not opacity per
500Hz-5KHz (alt) should be bright, blunt and not thoroughly
5KHz above (treble) should be thin, smooth and not shrill Park
When the flat frequency response: full and natural sound and flexible, clear layer
along pleasant garden. Frequency response of multi-peak hours: the rough sound
muddy, treble harsh scared, no layering prone to feedback howling sound reinforcement
