High-level inputs
High-level (speaker-level) connections can be made by connecting bare wire ends to the push-in terminal block.
Remove the terminal block and connect individual positive and negative wires to each screw terminal. After all
connections are secure, firmly re-insert the terminal block.
The high-level inputs have an input impedance of
68 Ω
and are designed for connection to the speaker outputs
of a head unit. The inputs are fully differential, therefore:
•
Amplifiers with bridged outputs can be used.
•
Do
not
connect the “–”
outputs together. This can potentially damage the amplifiers in your head unit.
The maximum (differential) input voltage is either 8 or 12 V RMS, depending on the input sensitivity switch
setting (see page 71). The 8 V RMS setting corresponds to a maximum amplifier power of 16 Watts into 4 ohms.
The 12 V RMS setting corresponds to a maximum amplifier power of 36 Watts into 4 ohms.
