The ALC262-GR/ALC262S-GR/ALC262SRS-GR/ALC262DTS-GR are 4-Channel High Definition Audio Codecs with UAA (Universal Audio Architecture), featuring two 24-bit stereo DACs and three 20-bit stereo ADCs, they are designed for high-performance multimedia desktop and laptop systems. The ALC262 series incorporate proprietary converter technology to achieve over 100dB Signal-to-Noise ratio playback quality, easily meeting PC2001 requirements and also bringing PC sound quality closer to consumer electronic devices.

The ALC262 series provide 4 DAC channels, supporting stereo sound playback on the rear panel and independent stereo sound output on the front panel simultaneously (multiple streaming), along with flexible mixing, mute, and fine gain control functions to provide a complete integrated audio solution.

The ALC262 series also integrate three stereo ADCs that can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously, significantly improving sound quality for PC VoIP applications. With this unique feature (3 stereo ADCs), the ALC262 can provide high-quality audio using S/PDIF to output analog data, or for multiple-source recording applications.

All analog IOs are input and output capable and can be re-tasked according to user's definitions. Headphone amplifiers are also integrated at analog output ports A, B, C, D, E, and F.

The ALC262 series support 16/20/24/32-bit S/PDIF input and output functions for both consumer mode and professional mode, and a sampling rate of up to 192kHz, offering easy connection of PCs to high quality consumer electronic products such as AC-3 decoders/speakers, and mini disk devices.

The ALC262 series support 16/20/24 S/PDIF input and output to offer easy connection of PCs to high quality consumer electronic products such as digital decoders and speakers.

The ALC262 series supports host/soft audio from the Intel ICH6/ICH7 chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent software utilities like Karaoke mode, environment emulation, software equalizer, HRTF 3D positional audio, and a choice of optional Dolby® audio technology, the ALC262 series provide an excellent entertainment package and game experience for PC users.

Applications:

• Multimedia desktop and laptop PCs
• 3D PC games
• Information appliances (IA)
• Voice recognition
• Audio conferencing
