ECC-50BDA Backup Remote Amplifier
Installation
3.2.7 Setting the ECC-50BDA Amplifier Mode
Set the amplifier dip switch SW4 for use with the ECC-50/100. The amplifier modes are as fol-
lows:
•
50 Watt with Backup - Amplifier A powers audio circuits 1 - 8. Amplifier A is backed up by
onboard Amplifier B. Set the dip switch to setting 2.
•
100 Watt with no Backup - Amplifier A powers audio circuits 1 - 4. Amplifier B powers audio
circuits 5 - 8. There is no backup in this configuration. Set the dip switch to setting 1.
•
100 Watt with Backup (requires ECC-50WBU) - Amplifier A powers audio circuits 1 - 4.
Amplifier B powers audio circuits 5 - 8. The ECC-50WBU will backup either Amplifier A
or
Amplifier B. Set the dip switch to setting 3.
3.2.8 Test Switch Use
SW1 - AMPLIFIER A
Switch should be moved to the “ON” position for normal operation. Move this switch to the “Test”
position to test backup amplifier.
SW2 - AMPLIFIER B
Switch should be moved to the “ON” position for normal operation. Move this switch to the “Test”
position to test backup amplifier.
3.2.9 Connecting AC Power
At installation, connect the AC terminals to the power source as shown in Figure 3.11. It may be
necessary for a professional electrician to make this connection.
