The Finished Product Test Procedure of aVERB II

6. TEST PROCEDURE

- 9 -

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), wh en 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.
