Analog Input Recording Function

The CMA18 Portable has two separate stereo line-in inputs - 3.5mm (AUX IN) and 4.4mm (BAL IN). They can be connected to any audio source with line-out analog outputs, including turntables, pre-amps, and mixing consoles. When connected, the CMA18 Portable can function as an external, lossless, high-performance analog-to-digital converter (ADC) for digital recordings. At the same time, the user can monitor the input via the 3.5mm or 4.4mm outputs.
