PCIe CM8828 Chip 7.1 Channel Internal Sound Card, PCI-E x1 Stereo Surround Audio Adapter with SPDIF Digital Output, 24Bit 192KHz Recording ASIO Support for Gaming Home Theater PC Desktop Audio Upgrade

This PCIe internal 7.1 surround sound card is built with C-Media CM8828 main audio processing chip, connecting to computer motherboard via universal PCI Express x1 slot, perfectly upgrading the limited built-in onboard audio of desktop PCs and bringing immersive multi-channel surround audio experience for gamers, music lovers and home theater builders.

It fully realizes complete 7.1 independent channel audio output, and is backward compatible with 2.1, 4.1 and 5.1 surround speaker systems. The sound card supports maximum 24-bit depth and 192KHz high sampling rate for both playback and recording, with up to 100dB signal-to-noise ratio and ultra-low harmonic distortion, effectively eliminating background noise, current buzz and audio distortion caused by motherboard electromagnetic interference, restoring richer sound details, deeper bass and clearer vocal performance.

Rich audio interfaces are reserved on the metal baffle, including multiple 3.5mm analog audio jacks for front, rear, side, center and subwoofer speakers, microphone input and line-in port. Independent SPDIF optical and coaxial digital output ports are available to transmit lossless digital audio signal to power amplifiers, decoders and active sound bars, realizing Hi-Fi level lossless audio decoding for movie viewing and music appreciation.

Equipped with embedded 8051 MCU and complete driver suite, the sound card supports professional ASIO low-latency drivers, which is ideal for live streaming voice recording, podcast production, small audio mixing and karaoke modification. The matched Xear control software provides powerful functions including surround sound simulation, magic voice changing, reverberation adjustment, volume balance and 3D sound field optimization, greatly expanding audio customization space.

Adopting high-quality filter capacitor layout and multi-layer PCB anti-interference circuit design, the card suppresses electromagnetic crosstalk inside the chassis during long-term stable operation. Standard full-height metal baffle ensures firm installation in PC case. It supports Windows XP, Win7, Win8, Win10, Win11 32-bit and 64-bit operating systems, widely applied in competitive gaming immersive sound positioning, 4K movie home theater systems, live broadcast audio recording, DIY HTPC host and studio simple audio production equipment.
