| Notes | Input & output signals are unbalanced to ground unless option O4 (transformer) is installed. One can use either an Envelope Follower, an Oscillator, or Remote control to vary the phasing effect, or set a fixed Manual level. Pseudo-stereo (Main+Aux) output, with phasing still present even when mixed to mono. Main output uses four Fixed Phase Shift sections, Aux output uses two. Units used by Isao Tomita, Yes, The Grateful Dead, Chicago, Led Zeppelin, Todd Rungren, Hot Tuna, The Edgar Winter Group, and over 100 major Studios, including CBS, EMI, Media Sound, The Record Plant, and Electric Lady. The beautiful old lamps on this unit are larger than LEDs and a joy to behold! |
