The  ALC269Q-VB6-CG  is  a  High  Definition  Audio  Codec  that integrates  a  2+2-channel  DAC,  a  4-channel  ADC, and a Class-D Speaker Amplifier.

The  2+2-channel  DAC  supports  two  independent  stereo  sound  outputs  simultaneously.  The  4-channel ADC integrates two stereo and independent analog sound inputs (multiple streaming).

The  ALC269Q-VB6-CG  incorporates  Realtek  converter  technology  to  achieve  a  98dB  dynamic  range  playback quality  and  a  98dB  dynamic  range  recording  quality.

It  meets  the  current  WLP3.10  (Windows  LogoProgram) and future WLP requirements.

The  ALC269Q-VB6-CG  also  supports  stereodigital  microphone  channels  (microphone  array)  with  Acoustic  Echo Cancellation  (AEC),  Beam  Forming  (BF),  and Noise  Suppression  (NS)  technology  simultaneously,

significantly improving voice quality for PC VoIP applications.

As well as basic audio functions, the ALC269Q-VB6-CG has two independent S/PDIF outputs; one could be used to connect  a  PC  to  high-quality  consumer  electronic  pr

oducts  such  as  digital  decoders  and  speakers,  the other could provide a dedicated digital output to a HDMI transmitter (common in high end PCs).

There  are  three  integrated  power  amplifiers.  The  first  is  a  linear  headphone  amplifier  at  port  C.  Thesecond headphone amplifier at port A removes the need for external DC blocking capacitors, eliminating

pop noise caused by these capacitors. The third is an integrated stereo Class-D

amplifier to directly drive a  mini-speaker.  The  Class-D  amplifier  is  designed  to  drive  speakers  with  as  low  as  4Ω

impedance.  Its maximum output power is 2.3W per channel at 5V power supply. The advantage of an integrated Class-D

amplifier in the ALC269Q-VB6-CG is high efficiency with low power consumption.

The  ALC269Q-VB6-CG  integrates  five  hardware  equalizer  bands  composed  of  one  low-pass  filter,  one  high-pass filter,  and  three  band-pass  filters  to

compensate  for  mini-speaker  frequency  response.  All  the  equalizer filters are programmable via the BIOS, allowing the equalizer to function without the need to customize the audio driver.

The ALC269Q-VB6-CG conforms to Intel’s Audio Codec low power state white paper and is ECR compliant.
