AMT OZZULATOR CH-2
GUITAR, BASS GUITAR CHORUS EFFECT
USER'S MANUAL
Thank you for purchasing the AMT CH-2.
Please take the time to read through this manual to become acquainted with the AMT CH-2.
INTRODUCTION
The AMT CH-2 device implements a chorus effect and is designed to work in the chain of guitar or bass guitar signal.
Chorus is a modulation effect simulating choral (polyphonic) sound of musical instruments.
When using this effect with a guitar, there is the illusion that not one guitar sounds but several ones at a time.
The effect is realized by adding to its original signal its own copies, delayed in time by values of the order of 10-20 milliseconds,
and the value of the time shift is continuously changing.
Features:
1- Small dimensions (Snickers-size).
2- A choice of one of two types of chorus effects (Chorus S or Chorus x3).
3- A wide set of the effect sound controls.
4- 100% analog direct signal in a mix with the effect signal.
5- Active bypass.
6- Ability to work as a part of the AMT Bricks Pedal board.
APPEARANCE, CONNECTORS AND CONTROLS
1- IN L - Left channel Input (TS - connector, 1/4").
2- IN_R - Right channel Input (TS - connector, 1/4").
3- OUT L - Left channel Output (TS - connector, 1/4").
4- OUT R - Right channel Output (TS - connector, 1/4").
5- Button to turn on/off the effect.
6- WIDTH - Determines how wide a modulation is produced.
7- RATE - adjusts modulation frequency (0.1Hz ... 10Hz).
8- MIX - sets the level of a processed signal when mixing with a direct signal.
9- DELAY- time delay regulator.
10-a LED indicator of modulation frequency (rate).
11-EXT.F - LED indicator. It is being used in a work with the AMT Bricks pedal board.

12-ON - LED indicator of the device's state (On/Off).
13-CH.TYPE - chooses a type of chorus. Upper position - Chorus x3 (Multiple voice Chorus with 3 Delay lines and sine
modulation. This chorus effect uses the same LFO to modulate all of the delays in sync but at different phases of the
oscillator cycle.) Lower position - Chorus S (Stereo Chorus with two Delay lines and square modulation. The delays
share the same oscillator and are modulated 180 degrees out of phase. This creates a richer chorus and a wider stereo
image).
14-COLOR - chooses the effect's brightness. Upper position - maximum, lower position minimum.
15-CTRL IN/OUT - a connector of external control (TRS 3,5 mm).
16-Signal connector for work with the AMT BRICKS pedal board.
17-DC 12V - power socket.
