GETTING STARTED

Before connecting the power supply to the power socket, 

make sure that 

the proper voltage is selected according to the mains of your country.

For US use 125V, for Europe 230V. 

Before turning the power supply via the main switch, make sure that all 
the cables are firmly connected to the preamp. Including headphone 
cable, XLRs and JACK cables. To preserve the long term performances 
of the preamp avoid detaching/connecting any of the cables while the 
Acoustic Box is powered on.

Before powering on the preamp make sure that the output knobs are not set 
to maximum. Keep in mind that XLR output knobs control the headphone vol-
ume as well. A good starting point for the output knobs is in the middle at 12 
o’clock. Turn  on the Abox using the power switch on the power supply and 
mute the output using the mute button on the Abox.

Power supply:

: 

Select the AC voltage corresponding to your local AC power 

(125V-230). 

Verify  using the light monitors that the pickup/mic are producing a signal in the 
channels. Disengage the mute button.

Ensure that the phantom voltage is correctly set via pref. menu. Condenser 
mics need phantom power. If you are using dynamic and ribbon mics turn off 
your phantom power.

Adjust impedance of your pickup. Try both setting and see which one is better 
for your pickup. Passive piezo prefer 

High impedance

 setting. Active piezo and 

magnetic coil prefer 

Med impedance.

Connect/disconnect your power connector to the Acoustic box II al-

ways when the power switch is OFF. 

If you need to plug in to your headphone connector while the unit is on, 

press the mute button before inserting the mini-jack in to the headphone 

connector.
