Basic connection and quick set-up

All loudspeakers need to be rigidly mounted to ensure a clear and focussed sound. Switch off your amplifier(s).
Check that the supplied terminal links are installed between the HF and LF inputs. For information on bi- wiring
and bi~amping see later. Always connect the -ve (usually black) loudspeaker output terminal of the amplifier to
the corresponding -ve (black) terminal on the loudspeaker. Always connect the we (usually red) loudspeaker
output terminal of the amplifier to the corresponding +ve (red) terminal on the loudspeaker. Always connect the
left channel amplifier output to the left loudspeaker and the right channel amplifier output to the right
loudspeaker. Make the connections as shown below (Fig 3). Turn the volume down and switch on the amplifier.
Pick a source (CD, FM etc.) and advance the volume carefully.

Bi-wiring
Bi-wiring improves sound quality by separating the current paths for Low (LF) and High (HF) frequencies. Make
the connections as shown below (Fig 4). Store the terminal links safely.

Bi-amping

Biamping allows two independent audio power amplifier of equal or similar quality to be used for LF and HF
signals. The benefits of bi-amping include reduced intermodulation distortion because the low and high
frequency signals are amplified independently, and more power reserve and dynamic range because each
amplifier has less work to do than a corresponding single amplifier. For bi~amping make the connections as
shown below (Fig 5). Terminal links MUST be removed before bi-amping. Store the terminal links safely.
