Advance Paris AIR 90
Advance Paris AIR 90 wireless speaker, compatible with Bluetooth A2DP and the aptX codec, designed to faithfully reproduce dematerialised music.
Description
The Advance Paris AIR 90 is a wireless speaker designed to play music stored on smartphones, tablets, computers or digital players. It is aimed at those who wish to listen to their dematerialised library on a hi-fi system without multiplying cables, whilst retaining a carefully crafted sound reproduction.
Its main strength lies in its Bluetooth connection compatible with A2DP, combined with the Apt-X codec. This codec allows a compression ratio limited to 4:1, bringing the quality of reproduction close to that of an audio CD for FLAC, Apple Lossless or PCM files. MP3 or AAC files with a bitrate not exceeding 350 Kbits/sec are transmitted without additional decoding, thereby avoiding degradation linked to double signal processing.
The speaker offers a dynamic range of 92 dB and a resolution of 16 bits, two elements that contribute to a listening experience with greater nuance and amplitude. Its frequency response extends from 10 Hz to 22 kHz, a wide range that allows both bass and treble to be reproduced with detail.
The AIR 90 is suited to portable or semi-stationary listening, for those who want to enjoy faithful sound without installing a full wired hi-fi system. It is aimed at users equipped with Bluetooth A2DP devices wishing to wirelessly stream quality audio files, including high-resolution files via the Apt-X codec.
What to check before buying used
When buying used, it is worth checking that Bluetooth pairing works correctly and that the aptX connection is stable, two sensitive points on this type of wireless speaker. It is also useful to check the condition of the power supply and speakers, and to confirm the absence of crackling or dropouts that could indicate wear of the internal electronic components.
