AirPort Extreme 802.11n - Technical Specifications model A1264

An updated version (MB321LL/A, model A1264) supporting the faster 802.11 Draft-N draft specification and operation in either of the and bands, with almost all other features identical, was introduced by Apple in March 2008. The revised unit includes an 802.11a/n (5 GHz) mode, which allows adding Draft-N to an existing 802.11b/g network without disrupting existing connections, while preserving the increased throughput that Draft-N can provide. Up to 10 wireless units can connect to this AirPort Express.

The AirPort Express uses an audio connector that combines a and a mini-TOSLINK optical digital transmitter, allowing connection to an external (DAC) or amplifier with internal DAC. Standard audio CDs ripped in iTunes into format streamed to the AirPort Express will output a bit-for-bit identical bitstream when compared to the original CD (provided any sound enhancement settings in iTunes are disabled). -encoded CDs ripped to Apple Lossless audio files - which decode as digital white noise in iTunes - will play back correctly when the AirPort Express is connected via TOSLINK to a DTS-compatible amplifierdecoder. This is limited to 16-bit and 44.1 kHz when streaming from iTunes; any higher quality content, such as high fidelity audio that uses up to 24-bit and/or 192 kHz will be truncated down to 16-bit and 44.1 kHz.
