Description

– 5-band graphic EQ

The STA308A is a single chip solution for digital

audio processing and control in multi-channel

applications. It provides output capabilities for

– 32 preset EQ curves (rock, jazz, pop, etc.)

– Automatic volume controlled loudness

– 5.1 to 2-channel downmix

DDX (direct digital amplification). In conjunction

– Simultaneous 5.1- and 2-channel downmix

outputs

– 3 preset volume curves

with a DDX power device, it provides high-

quality, high-efficiency, all digital amplification.

The device is extremely versatile, allowing for

input of most digital formats including 6.1/7.1-

channel and 192 kHz, 24-bit DVD-audio,

DSD/SACD. In 5.1 application the additional 2

channels can be used for audio line-out or

headphone drive. In speaker mode, with 8

channel outputs in parallel, the STA308A can

deliver 1 W (maximum).

– 2 preset anti-clipping modes

– Preset movie nighttime listening mode

– Preset TV channel/commercial AGC mode

– 5.1, 2.1 bass management configurations

– AM frequency automatic output PWM

frequency shifting

– 8 preset crossover filters
