The expert sleepers esx 8cv mk2 is an expansion module that is designed to work with the es 4 es 40 or es 5. The esx 8cv adds 8 cv outputs from one expansion header allowing for seamless integration. Each channel is time multiplexed and runs between one third and one twenty fourth of the audio sample rate fast enough for most cv purposes which guarantees high quality performance. As the outputs are derived from the audio stream the expert sleepers esx 8cv retains super accurate timing and is jitter free. Additionally the esx 8cv features illuminated jack sockets that provide you with visual feedback of outgoing signals. Expert sleepers modules are designed to take audio signals generated by your computer and convert them into voltage values that allow interaction with your modular system.
