Yamaha E1005 E1005 Owners Manual Image - Page 2

This instruction manual was prepared to assist you in getting the most out of your E1005. While you may already have begun using the unit, we urge you to read this manual thoroughly, and to re-read it as you become more familiar with the E1005's features and functions. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. 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 with controls that enable it to create chorus, double-tracking, flanging, and other special effects. A foot switch jack enables musicians to conveniently turn the effects On and Off. One output carries an adjustable blend of direct and delayed signal, enabling the E1005 to be used without an external mixer. A second output carries delayed signal only for stereo synthesis, pure delay, and other effects. Guitarists, keyboard players, and others will enjoy the way the E1005 creates echo and related effects without the mechanical disadvantages of older tape-loop echo machines. A very high input impedance ensures that the delay line will not load high impedance instrument pickups, so regardless of the delay settings, the direct sound will retain its full frequency response. All controls are clearly labeled and are recessed to avoid inadvertent changes in settings (recessed controls are also safer in shipping and cartage). Unlike devices designed strictly for the studio, the E1005's input and output jacks are front panel mounted so patch cables can be kept shorter in musical instrument amplification systems. What is an analog delay line? It is a device that provides echo and related effects by slowing down audio signals---a more capable space-age alternative to older tape-loop echo machines. The term "analog" means that the audio signal retains its original voltage levels throughout the electron- ics; this differs from "digital" delay lines, where the signal is converted and stored as binary numbers.
