The PGA2311 device is a high-performance, stereo
audio volume control designed for professional and
high-end consumer audio systems. The PGA2311
uses an internal high-performance operational
amplifier to yield low noise and distortion.

Device functions:

- Volume adjustment -95.5dB to + 31.5dB with a step of 0.5dB

- Volume control with remote control and encoder

- Balance adjustment (remote control and encoder control)

- Mute function (remote control)

-ON / OFF (remote control and switch control)

- Memorizing settings after switching off

- Real time clock + date based on PCF8583

-Cooperation with popular 2x16 displays with HD44780 driver.

- RC5 pilot (each Philips)

- Input select (5 sources)

The program was written in Bascom, it takes 51% of the memory
Fuse bits set on internal 8Mhz dnt forgot turnoff JTAG

ps.
I am asking for opinions what you think about such a device
