Connections
3.1 4 channels configuration
4 CHANNELS AMPLIFICATION OUTPUT CONNECTIONS
Observe correct polarity in speaker
connection to have output signals
in phase with the input ones.
IMPORTANT :
•
Do not connect outputs among them or to others amplifiers outputs.
•
Do not short circuit the outputs.
•
To connect the speakers use the appropriate cable section depending on the connection
length. Reduced section cables cause power loss along the line with, consequently, cable
heating.
4 CHANNELS AMPLIFICATION INPUT CONNECTIONS
BALANCED INPUT:
Pin 1: ground
Pin 2: reverse phase signal
Pin 3: in phase signal
UNBALANCED INPUT:
Pin 1: ground
Pin 2: ground
Pin 3: in phase signal
IMPORTANT :
• 20Kohm nominal impedance inputs.
• For unbalanced signals is mandatory to connect together pin 1 and 2.
