The E1005 Analog Delay Line provides variable time delay up to a full 400 milliseconds. The unit is equipped with both a mic input and a switchable mic/instrument input, each with its own input level control. A bar type input level display makes it easy to adjust the levels for low distortion and noise. The unit is equipped for controls that enable it to create chorus, double-tracking, flanging, and other special effects. The Yamaha E1005 is a more capable space-age alternative to older tape-loop echo machines.
