The USB 500 Rack 500-Series USB Audio Interface from Aphex is a four-slot 500-Series module rack with a built-in USB audio interface. It is designed to allow you to use your 500-Series modules directly with your DAW. It is capable of handling digital audio up to 24-bit/96kHz and accepts audio directly from any 500-Series module. The USB 500 Rack has four analog XLR inputs and outputs for the 500-Series modules. You can route the analog output of all of the 500-Series slots directly to the audio interface or the XLR outputs. The modules can also be configured in a series or linked together, resulting in channel strip or stereo operation, depending on your installed modules. Empty slots can be used as line inputs for the audio interface.
The built-in audio interface features two 1/4" TRS Main Outputs and S/PDIF connectors that provide two additional channels of input and output. It also features a clock input and output as well as 5-pin DIN MIDI connections. Because it is integrated with the 500-Series rack, you can use your installed modules as hardware insert processors for your DAW. The USB 500 Rack features Mono and Dim buttons on its Main Outputs as well as two 1/4" headphone outputs with independent volume control.
