Dukane 250 Watt Amplifier, Rear View
A 1 Volt RMS signal is required at the Unbal Hi-Z input to provide full
rated power out. Depending upon the total number of amplifiers
required for each channel, the preamplifier output of the FCCA must
be terminated with the appropriate end-of-line (EOL) resistor at the last
amplifier on the pre-amp riser. The table below lists the appropriate
EOL for different quantities of amplifiers in the system.
ATP Pre-Amplifier Termination
# Of Amplifiers Per
Channel EOL Resistor Value P/N
0 10K Ohm, 1/2 watt 260002
1-5 1.8K Ohm, 1/2 watt 260044
6-10 2.2K Ohm, 1/2 watt 260045
11-15 3.0K Ohm, 1/2 watt 260046
16-20 3.9K Ohm, 1/2 watt 260001
21-25 6.8K Ohm, 1/2 watt 260047
Note:
A DAPM may be installed at the pre-amp source and tuned for 1
VRMS. This would alleviate the need for the above resistors.
