Sound Blaster Audigy Rx 7.1 sound card

The Creative Labs Sound Blaster Audigy Rx is a PCI Express x1 sound card that upgrades basic motherboard audio to 7.1 multi-channel surround sound. It uses the Creative E-MU chipset to process the EAX reverb engine for enhanced audio effects in games and movies. The card supports 24-bit 192 kHz stereo playback with a 106dB signal-to-noise ratio. A 600 ohm headphone amplifier provides studio-grade monitoring for high-impedance headphones.

Installation experience

The card fits a standard PCI Express 1.0a compliant x1 slot and includes an installation CD plus a quick start leaflet. System requirements call for a 2.0 GHz Intel Core2 Duo or equivalent AMD processor, 1 GB RAM and over 600 MB of free disk space. Supported operating systems range from Windows XP SP2 through Windows 10. Common issues involve driver conflicts with onboard audio, so disabling the motherboard codec in BIOS before installing the card is recommended.

Who this suits and who it does not

This card suits PC builders who want hardware-accelerated EAX effects and a dedicated headphone amplifier for high-impedance cans. It also fits users needing multiple analogue outputs for a 7.1 speaker system plus dual microphone inputs. Buyers who require external digital input, more than one optical output, or a low-profile bracket should look at other options.

Questions about this item

How can I verify the card is working after installing it in a PCI Express x1 slot?

In Windows Sound settings the device appears as Sound Blaster Audigy Rx with 7.1 channel support; playing a test tone lights up all eight speaker icons and the Control Panel reports 24-bit 192 kHz playback.

What does the package contain and what must I provide?

The box includes the Audigy Rx card, a Quick Start leaflet, an installation CD and warranty leaflets; you must supply a Windows 10, 8, 7, Vista SP1 or XP SP2 system with a free PCI Express x1 slot, 1 GB RAM and 600 MB disk space.

Which version of the Audigy Rx should I choose for 600 ohm headphone monitoring?

The single model 70SB155000001 already integrates the 600 ohm headphone amplifier, dual microphone inputs and 106 dB SNR, so no alternate capacity or version exists to select.
