ADA 64i-1.28i-2.56i owners manual
LED indicates REPEAT HOLD is engaged.
DELAY RATE
An LED indicator that "blinks" at the rate of the delay time
interval.
DELAY RANGE
Interlocking pushbuttons for selection of the delay time range.
DELAY MULTIPLIER
Allows a continuous 0.125X to 1X adjustment of any selected
delay range.
MODULATION DEPTH
Determines the range of delay time that is swept by the low
frequency oscillator.
MODULATION LEDS
Pair of LEDs indicates the speed, direction, and position of the
sweep as it moves up and down.
MODULATION SPEED
Sets the speed of the low frequency oscillator that sweeps the
delay time. Sweep speed varies from 0.1 sec to 25 seconds.
MODULATION WAVEFORM
Continuously blends the shape of the sweep modulation from a
triangle to sine to square wave.
TRIANGLE LED
Indicates power is "ON".
2.1 REAR PANEL
FUSE
Externally accessible 0.5AMP fuse. Replace with equivalent
type and rating only.
POWER SWITCH
ON/OFF rocker switch (located near power supply to prevent
the leakage of AC line hum into the audio circuitry).
REMOTE
Remote control of EFFECT BYPASS and REPEAT HOLD
functions. Used with standard ¼” stereo cord and-dual
footswitch (momentary type).
EFFECT OUT
A 600 ohm unbalanced output. The level is set with the
OUTPUT LEVEL control and carries the mix of dry and delayed
signal set by the OUTPUT MIX control.
DIRECT OUT
A 600 ohm unbalanced output of dry signal only. The level is
the same as the input signal level.
INPUT
An unbalanced high impedance input which interfaces with low
or high impedance sources and low and high signal levels.
FIGURE 3-1 INITIAL FRONT PANEL SET-UP
3.0 INITIAL SET-UP
ADA DIGITALS interface with a wide variety of input sources including high level
microphones, electronic instruments and mixing consoles. The INPUT circuitry is high
impedance which functions properly with both low or high impedance sources and low (-
10dBV) and high ( + 24dBV) signal levels.
(A) To prepare your DIGITAL DELAY for use, set the rear panel POWER SWITCH to the
"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.
(D) Connect your signal source to the INPUT jack located on the rear panel.
(E) Connect the EFFECT OUTPUT on your DIGITAL DELAY to your amplifier input or
mixing console effects receive input. The DIRECT OUTPUT is used with a second
amplifier for stereo effects.
