Para Acoustic DI is a direct box with a five-band equalizer that includes a tunable notch filter, midrange filters and low cut filter. Powered by a single nine volt battery for over 200 hours of operation or from 30 to 48 volts phantom power, Para will interface any acoustic guitar, bass, violin or any instrument that uses a magnetic or piezoelectric pick up. The Para Acoustic uses an ultra high input impedance (10megaOhms) and a Class A FET (Field Effect Transistor) amplifier circuit coupled to their Quasi-Passive EQ™ which is said NOT to pass the guitar's signal through any active stages to affect an EQ change.

The unit provides a 600 ohm impedance line level output and has a signal to noise ratio of -88dB, unweighted. The five bands of EQ are: +/- 12B at 85Hz for bass; +/- 6dB tunable from 98Hz to 247Hz for feedback notching; +/- 12dB tunable from 400Hz to 1.6kHz for covering mid-range carving; +/- 6dB @ 5kHz presence; and +/- 12dB @ 10kHz treble. There is also a 12dB/oct @ 35Hz fixed rumble/dethumper filter.
