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
