Palmer PAL-PAN02 Standard Powered DI BoxStandard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High impedance input; higher output level than with a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out 4 dB). Maximum output impedance with phantom power operation +10 dB. Output: transformer balanced. The special "floating ground" circuitry enables ground lift even during
