The ATT100-T42 is designed to interface a 100V line speaker system to a
balanced line-level input such as those found on some Ampetronic loop
drivers. The unit provides a transformer isolated attenuation of 40dB.
Restrictions on usage
The ATT100-T42 is not suitable for use with unbalanced and microphone
inputs. It should only be connected to inputs intended for balanced line-level
signals.
1. Output connection.
The ATT100-T42 is terminated in a 6.3mm 3 pole jack plug. This should be
plugged directly into the balanced line input of the Ampetronic loop driver.
Note the restrictions listed above.
Under no circumstances should the output be extended, not even using a
screened cable. The extended connection would be susceptible to
interference.
2. 100V line connection
The 100V speaker line should be connected to the 3-pin input plug as shown
below.
Plug into ATT100-T42.
Adjust Input Gain on amplifier as required.
