Generate into or monitor from your AES digital sound system with this handy tool. Also doubles as a quality A/D and D/A converter and impedance transformer. For those that require native output generation of 44.1kHz or 88.2kHz sample rate.(Original AESQbox generates 48k, 96k or 192kHz). Still recognizes and passes through various input sample rates - 32k, 44.1k, 48k, 88.2k, and 96kHz.(Original AESQbox recognizes 32k, 44.1k, 48k, 88.2k, 96k, 176.4k, and 192kHz).
