captainbeefheart Posted March 12, 2022 Share Posted March 12, 2022 A little education for some folks after reading some comments about digital volume controls throwing away information. While some software based systems can degrade the sound this is by far not true for the vast majority of devices that use a "digital volume control". I will attach a datasheet for a PGA2310 digital volume control IC. "The heart of the PGA2310 is a resistor network, an analog switch array, and a high-performance bipolar op amp stage. The switches select taps in the resistor network that determine the gain of the amplifier stage. Switch selections are programmed using a serial control port. The serial port allows connection to a wide variety of host controllers." Many companies use this IC including McIntosh Labs for their digital volume control systems. It will not degrade your sound by throwing away information, that's just not how it works. Think of it as a digitally controlled precision analog volume control. https://www.ti.com/lit/ds/symlink/pga2310.pdf 1 Quote Link to comment Share on other sites More sharing options...
