Conceived to enhance all sound, the SHA900 was engineered for both earphones and headphones, your way, anywhere. Take control of the music with sophisticated customizable EQ function, allowing you to fully tune the tonal balance for your own sound signature.
Not only work as a DAC amplifier, SHA900 also equipped with 4-band parametric EQ which features five preset settings, and four customizable settings, allow you to enjoy the original source or customize the music to suit your unique taste.
Most of the amplifiers only work for high impedance devices, but we intended to design the SHA900 to have Wide impedance acceptance from 6 Ω to 600 Ω. Providing premium sound quality for both earphones and headphones with maximum flexibility.
With digital music streaming through mobile devices getting more popular, SHA900 is designed for perfect cohesion with smartphones including EMI filter to prevent electromagnetic interference from mobile phones without sacrificing audio quality
(Line in or USB in) - Frequencies at and below 125Hz are boosted by 5dB resulting in an increased energy of the low frequencies.
(Line in or USB in) - Frequencies from 2k to 5k are boosted to increase the clarity and detail of most of the lead instruments such as violin, guitar and also human voice. This preset can also called Clarity preset.
(Line in or USB in) - This setting helps to accentuate the frequencies that can seem to be muted when listening with lower volume settings. Since our hearing has different relative sensitivities based on frequencies at different volume, the volume level can affect how we perceive the overall tonality.
(Line in or USB in) - This setting helps to tame a harsh piece of music, traditionally a vocal piece that has an accentuated sibilance sound – often created when the singer produces the “S” sound. This sibilance falls into the frequency range somewhere between 4kHz and 10kHz.
(only when using USB input) - This setting has no effect on the source material, all 4 of the frequency filter points are set to Zero.
