E1005 Analog Delay

The Yamaha E1005 Analog Delay Line provides variable time delay of up to 400 milliseconds. It is equipped with both a mic input and a switchable mic/instrument input, each with its own input level control. The unit features controls that enable it to create chorus, double-tracking, flanging, and other special effects. Additionally, a foot switch jack allows for convenient on/off control of the effects.

The E1005 offers two outputs: one carries an adjustable blend of direct and delayed signal, enabling standalone use without an external mixer, while the second output carries delayed signal only for stereo synthesis, pure delay, and other effects. The high input impedance ensures that the delay line will not load high impedance instrument pickups, allowing the direct sound to retain its full frequency response regardless of the delay settings.

All controls are clearly labeled and recessed to avoid inadvertent changes in settings, and the front panel-mounted input and output jacks enable shorter patch cables in musical instrument amplification systems. The analog delay line provides echo and related effects by slowing down audio signals, offering a space-age alternative to older tape-loop echo machines. The term "analog" indicates that the audio signal retains its original voltage levels throughout the electronics, distinguishing it from digital delay lines where the signal is converted and stored as binary numbers.
