The Finished Product Test Procedure of aVERB II
6. TEST PROCEDURE
1. Test Instruments:
a. Dual oscillagraph
b. AP (ATS-2 or System Two)
c. AC power supply or AC/DC Adapter: 9V
2. Instruments setting:
a. Connect the signal generator or AP output signal to L (Mono) Input (unbal-GND, 20 Ohm
Z-Out), and the AP input to L, R (BNC-Unbal).
b. BW: 22Hz 22 KHz, FLTR: A Weighting.
c. Adjust the AP output signal to sine waveform 1 KHz, -20dbm.
3. Test Procedure:
a. After connecting the voltage converter (9V) to the AC socket, the PWR (Red) will light up.
b. Rotate the “VARIATIONS” (the smaller knob) to “1” position, and the “PRESETS” (the larger
one) to “ HALL1” position.
c. Rotate the “INPUT”, “OUTPUT” knobs to maximum, the ”MIX” to minimum, the L/R output
signal is -20dbm (±2dbm), when rotate the “INPUT”, “OUTPUT” knobs to minimum, there is
no output signal. (Rotate the “INPUT”, “OUTPUT” knobs to maximum after the test is
finished)
d. rotate the “MIX” knob to maximum, L: -14dbm ( 2dbm), R: -20dbm ( 2dbm). During rotating
this knob from minimum to maximum, the effect will be changed.
e. The “ PRESET” knob has 16 functions in this aVERB II, the testing parameter please see the
below table (the “ LEVEL” parameter is the reference).
No. PRESETS L-OUT/R-OUT LEVEL (±2dbm) Note
1 HALL1 -14.0 dbm/-20 .0dbm
2 HALL2 -11.0 dbm/-8.0 dbm
3 HALL3 -19.0 dbm/-13.0 dbm
4 SPRING1 -18.0 dbm/-17.0 dbm
5 SPRING2 -18.0 dbm/-19.0 dbm
6 TAPE -17.0 dbm/-17.0 dbm
7 PLATE1 -16.0 dbm/-27.0 dbm
8 PLATE2 -17.0 dbm/-17.0 dbm
9 TREMOLO XXX
10 CHORUS -17.0 dbm/-17.0 dbm
11 FLANGE XXX
12 DELAY -16.0 dbm/-16.0 dbm
The signal will be changed (-17 -19
-17 dbm)
The signal will be changed (-9 -26
-9 dbm)
No. PRESETS L-OUT/R-OUT LEVEL (±2dbm) Note
- 10 -
13 DELAY/REV. -11.0 dbm/-14.0 dbm
14 FLANGE/REV. XXX The changed signal (the waveform
strongly changed)
15 CHORUS/REV. XXX The changed signal (the waveform
strongly changed)
16 ROTARY XXX The changed signal (the waveform
strongly changed)
f. Rotate the “ VARIATIONS” (the smaller one) from “1” position, the effect will be changed (it
presents the waveform will be strongly changed), and the “ SIGNAL” (red) LED will blink.
g. rotate the “MIX” knob to minimum, connect the AP output to Right Input, at this moment, only
the “R” has output, rotate the “PRESET” (the larger knob) to “Delay” position, and the
“ VARIATIONS” (the smaller one) to “1” position, also the “MIX” knob to maximum, the sweep
frequency response curve as below:
h. Test for “BYPASS”: rotate the “ MIX” to maximum, connect the footswitch to “BYPASS” jack,
this footswitch can control the DSP effect.
i. When turn off the input signal, the output noise is <-70dbm.
j. Spot-check: to know if there is another noise and the DSP effect is OK.
k. Factory Preset: rotate the “INPUT”, “OUTPUT”, and “MIX” knobs to minimum, the
“ VARIATIONS” (the smaller knob) to “1” position, and the “ PRESETS” (the larger one) to
“ HALL1” position.
