Compressor/Mixed channel Ch1+Ch2 EQ
The new Acoustic Box II comes with an optical compressor and a 3 band
parametric eq. The mixed channel is the signal obtained by adding the
processed channels Ch1 + Ch2 after the compression. Each individual
channel contribution is set by the LEVEL control knob (see p.8 and p.9 )
Compressor
The optical Compressor provide up to 16dB compression. It is engaged where
the Comp button is engaged. Otherwise the Compressor is bypassed.
The level of Compression can be set with the SENS knob. If Sensitivity is set to
minimum no compression (0dB) is performed. Once the desired compression
level is set, use the MAKEUP gain knob to adjust the output level. The LED indi-
cator on the compressor turns on when compression of 10 dB is obtained.
Phase ALL button (øAll)
When the ALL button is pressed, it allows for 180° phase shift between
(Ch1+Ch2) and the acoustic signal. This button is handy for controlling the
feedback and for getting a good bass response of the blended signal on your
acoustic sound.
Parametric Equaliser
To equalize the mixed channels the Abox uses a 3 band parametric eq Low-
Mid-High (40Hz - 125Hz, 250Hz - 1KHz, 3.5KHz - 12KHz respectively) by correcting
within +/-12dB designed to help you adapt on any situation of sources and
combination of inputs.
Master mute/Tuner mode
By Pressing the Mute button the preamp mutes all outputs and gets into tuning
mode as indicated on the display. The tuner receives signal measurement only
from Ch1 therefore Ch2 can't be used for tuning. Play your string and tune
until you see the tuner highlighting the circle in the middle of the display. Once
the string is tuned, hold your strings until the tone on display clears up.
Ó
LEVEL AMP
The LEVEL AMP knob allows you to control the output signal level that is
directed into your AMP via the unbalanced Jack (AMP output).
LEVEL XLR L and XLR R
The LEVEL XLR L and XLR R knobs allow you to control the output signal level
connected to your PA/MIXER via XLR balanced cables. Abox II comes with two
XLR knobs since it controls stereo effects (both internal and external).
Those knobs control as well the Headphones output.
