4.7. DLAPACK2-70

The DLAPACK2-70 is a dual line adapter converting two low impedance (4 ohms)
amplified signals in two signals suitable to work at high impedance (70 or 100V line). In this way, it is
possible to use an AMPACK2-70 or AMPACK4-70 to connect a high impedance speaker system
(you have to use two DLAPACK units with the AMPACK4-70 and one unit with the AMPACK2-70).
The connection must be made as follows:
1.
2.
In both types of connections always respect signals and wiring polarity.
NOTE: in this type of installation, it is recommended to activate the 100Hz high-pass filter.

5. CLEANING

The AMPACK should not be cleaned with dissolvent or abrasive substances because
silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid
soap; dry it with a clean cloth. Be careful that water never gets into the amplifier through the holes of the
front panel.
10
With all equipment disconnected from mains, connect one at a time the outputs
of the AMPACK2-70 or 4-70 to the inputs of the DLAPACK.
Then connect the DLAPACK outputs to the high impedance speaker system,
using for them the 0V (or negative) and 70 or 100V (positive) terminals
depending on whether this system's speakers are equipped with 70 or 100V
transformers.
