Operating Modes
The most frequently used operating mode of a power amplifier is stereo operation, where both channels are
operated independent of each other. In parallel operation the power amplifier can be operated in mono
mode, i.e. via one input channel. The voltage remains the same, the current is doubled. Consequently, the
output impedance is limited to the minimum value of one individual channel. In bridge operation the power
amplifier can be operated in mono mode, i.e. via one input channel. The voltage is doubled and
subsequently also the output impedance. For stereo operation two amplifiers are needed. Always make sure
the power amplifier's selector switch for the operating mode is set accordingly.

Making the Connections

The subwoofer is equipped with 4-pole, lockable Speaker sockets that are wired in parallel and can be used
as input and output as desired. For locking the connection turn the plug to the right. For unlocking pull the
unlock button and turn the plug to the left and pull it out of the socket.

Information on installing audio cables
• A good cable run improves the sound quality remarkably. Avoid long cable runs.
• Always treat cables carefully and protect them from damages during transportation.
• Install cables always in a structured way and protect them from damage.
• Cables must be installed in a way that no person can stumble over them. Always fix cables with an
appropriate tape.
• Cables should be installed directly (no loops, S-shaped overlengths).
• Always install cables far away from power cables (never closely parallel).
• Never put heavy objects like speaker systems, flightcases etc. on cables.
• Never operate cables wound up.
