2. GENERAL
DESCRIPTION
The
PMD
ampli
fi
er is able to provide a large range of functions, such as:
• line impedance measurements;
• amplifier diagnostics;
• check and insulation of the short-circuited speaker lines.
• check of insulation to earth (GND FAULT);
• volume control;
• selection of two inputs;
• possibility of including the LOW CUT filter.
These amplifiers can also be controlled via a serial interface. In addition to carrying out all the operations and/or checks set locally by means of the dip
switches, it will also be possible to display and alter all the parameters, including the following:
• reading of the reference impedance for the test;
• minimum and maximum values between which the test is valid;
• reading of the test status;
• testing of the inputs;
• measurement of the temperature of the end transistors;
• volume adjustment.
Model: PMD500-V
