ADA 64i-1.28i-2.56i owners manual 1.0 INTRODUCTION Thank you for purchasing one of our professional ADA DIGITAL DELAYS, The .64i, 1,28i, and 2.56i combine the latest in digital technology with innovative, yet cost effective designs. They fulfill your long delay and special effects processing needs with fuli bandwidth at all delay settings, more useful features, and better sound quality than anything else in their respective classes.
"OFF" position. Also set your amplifier's power switch to the "OFF" position. (B) Connect your DIGITAL DELAY'S AC CORD to a grounded outlet. (C) Set the front panel controls as shown above (Figure 3-1). ,64i and 2.56i owner's should use the longest delay factor pushbutton, 640rns and 2560ms respectively.
Room ambience or naturally reflected sounds are quite different from the original signal because reflective surfaces of a room absorb high frequencies more quickly than low frequencies. ADA DIGITALS can simulate room acoustics by rolling-off the higher frequencies with the continuously variable REGENERATION HI-CUT control. At minimum cut (16kHz), the delayed signal is not altered.
ADA 64i-1.28i-2.56i owners manual regenerated signal content above the mid-range frequencies is attenuated to simulate highly damped room acoustics. The frequency spectrum of the sound source generally decays as it would in a natural environment. 3.4 PHASE The delayed signal's phase is inverted when the PHASE pushbutton is engaged. "Inverted phase"...
4.0 PATCH DIAGRAMS IMPORTANT NOTICE: .64i OWNERS SHOULD USE DIAGRAMS OF 2.561 TO SET FRONT PANEL CONTROLS, AS THE FIRST FIVE DELAY PUSHBUTTONS ON THE 2.561 ARE IDENTICAL TO THE THOSE ON THE .64 FIGURE 4-1 / CLASSIC FLANGE This demonstrates the full 8:1 sweep range of your digital delay.
ADA 64i-1.28i-2.56i owners manual FIGURE 4-3 / THICK CHORUS This is a dramatic, very deep chorus. Adjust the SPEED control for the desired effect. FIGURE 4-4 / STEREO DOUBLING The OUTPUT MIX control is set at full delay (10) for double tracking when using the DIRECT OUTPUT and the EFFECT OUTPUT in a stereo PA or recording system.
ADA 64i-1.28i-2.56i owners manual FIGURE 4-6 /REPEAT HOLD This captures, stores, and repeats a segment of sound without signal degradation. The pitch and repeat rate may be modified by using the DELAY MULTIPLIER control. Many useful special effects can be produced by varying the MODULATION DEPTH and SPEED controls.
