DESCRIPTION

The Active Direct Inject box shall provide a
transformer balanced and isolated feed from a source input via a
1/4" TRS jack. The output of the DI box shall be via an XLR
connector. The unit shall also provide a 1/4" TRS jack in
parallel with the input to act as a link for line bridging. The unit
shall be self-powered via a main and standby battery system, or
optionally through a phantom power source. An led shall indicate
when battery power is low. Switches shall be provided for: PHASE
REVERSE, EARTH LIFT (input/output), INPUT ATTENUATION of 0, 20 or
40dB), and the insertion of a LOW PASS FILTER, with roll-offs at
4kHz or 8kHz. The unit shall be housed in an isolated rugged ABS box
to prevent accidental shorting when located on metal equipment.
