Description

Product size: 117 * 131mm Weight: around 100g
Input voltage: DC 5V 500ma DC ± 15V 200-500ma
Signal input method: SPDIF and 1IS (BCK LRCK DATA GND) Output: Audio analog signal stereo
Supported formats: SPDIF OPTICAL BNC with three inputs, pcm24 bit, supports sampling rate display of 44.1khz 48khz 96khz 88.2khz 176.4Khz 192khz
The LIS PCM supports a 4-bit sampling rate of 44.1khz~384khz and does not display the sampling rate (384khz is only for decorative use and not for actual sampling rate display)
DAC type: Positive and negative DAC complementary design, discrete resistor stepped design
Advantages: There is no requirement for a clock, and signal decoding is triggered by the use of data bits, allowing for accurate analog-to-digital conversion. As is well known, the process of R2R processing is closest to analog signals, so it has a good listening experience.
The simplest way to determine the design quality of a discrete resistor array DAC (without professional testing equipment) is to adjust the volume to near the minimum volume through IIS input, about -6ODB, and when it approaches mute at -8ODB, play music and use headphones to monitor. At this time, the volume of data is effectively reduced, while background noise is not effectively reduced. When the popular rap voice is low, the environmental noise remains unchanged. This environmental noise is the background noise, which directly affects the overall quality and cannot be ignored. Our complementary R2RDAC is designed to solve the problem of background noise that cannot be heard by humans, which means that a channel must have two. The R2R circuit of the sound channel is used for compensation processing. The background noise is processed to a level that is inaudible to the human ear. The main feature is a decoding board that listens to music well. Those who play equipment testing can bypass it. If you need high performance parameters, our store has ES9039Q2M to ensure it is sufficient for you to test.
