DI-010 ACTIVE DIRECT INJECTION BOX
Input Side
The input side is equipped with one
Neutrik Combo connector (1/4"
stereo jack + XLR-3 female) and
one RCA connector per channel.The
Combo and RCA connector of one
channel are paralleled.
Output Side
The output side is equipped with
one XLR-3 male connector per
channel.The transformers are
connected between the two (input
and output) sides of the box.
The presence of different connector
types make matching between
different standards possible (e.g.
RCA or jack to balanced XLR,or
unbalanced XLR to balanced XLR).
Ground Lift
The 'ground-lift' switch has 3
positions. In the centre position the
'grounds' of the connectors on both
sides of the box are connected to
the metal pieces of the box and to
the screen of the transformers. In
the other 2 positions of the switch
respectively one of both sides of the
box is 'ground lifted' (the other side
remains grounded).
TR-2 DUAL CHANNEL TRANSFORMER BOX
The ASL active DI-box is phantom powered only and is designed to satisfy the needs of professional
users, operating in the various fields of the pro audio industry such as Broadcast, Recording and Sound
Reinforcement.The unit is comfortable and safe to operate and it does not affect the quality of the
original signal path. By having a transformer coupled DC-DC converter and an output balancing
transformer on board, there's always 100% galvanic separation between the input and the output of
the unit.

(Input side)
The box is provided with two (input and loop-thru) 1/4" jack connectors, an
XLR-3 output connector,an attenuator switch,an HF-cut switch and two
LED's which indicate the status of the phantom power.
Transformers are sometimes the only way to interconnect audio
equipment safely and properly.The TR-2 contains transformers with
professional (broadcast) specifications and all the required
connectors.
The box is equipped with two high quality line transformers which can
handle signal levels up to +26 dBu.
The transformers are housed in a strong metal box,covered with a plastic
'skin'.This ensures the boxes can not make conductive contact with the metal
housings of other audio equipment,possibly causing undesirable ground
loops.
