The use of separate cables to each half of the crossover then enables the complete isolation of the signals fed from the amplifier to the treble and bass speaker units. A reduction in low level intermodulation and crosstalk effects is achieved, resulting in a cleaner sound with improved imaging and separation of instruments. To bi-wire a loudspeaker you must remove the two links between the pairs of red and black terminals on the rear of the speaker and then connect two separate cable runs to the bass and treble inputs. These cables should then be connected together at the amplifier's output terminals. This may be done by connecting both cables into a single pair of 4mm plugs or by making common bare wire or spade connections to the terminals. Bi-amping Bi-amping is a similar principle to bi-wiring, except that two stereo amplifiers are used to drive the loudspeakers instead of one. To bi-amp, connect the treble units to one of the amplifier's outputs, and the bass units to the other amplifier. Both amplifiers must be fed from a common stereo signal and must be of equal gain. Arcam models such as the Delta 290 and Delta 290P are ideal for this application. Bi-amping offers a further improvement over bi-wiring, as separate amplifiers are dedicated to treble and bass frequency bands, with less internal intermodulation effects occurring in each amplifier. You must remove the links on the rear of the loudspeakers for bi-amping. otherwise you will damage your amplifiers. Care must also be taken to ensure that all individual loudspeaker uniti are connected in the same phase (i.e. connect terminals RJED to RED anc BLACK to BLACK). If tni> is not done serious frequency response deviations will resuit. Power Handling Arcam loudspeakers are designee to reproduce recorded music under normal domestic conditions. We do not recommend nor warrant them for use in any form of sound reinforcement application or at discothèques, parties or other forms of speaker demolition contest. Bearing this in mind the loudspeaker will perform well and safely with hi-fi amplifiers rated at between approximately 40 and 150 watts per channel. However care must always be taken to avoid amplifier overload or "clipping". If you hear distortion from the loudspeakers, then reduce the volume level at once, as this is a clear sign of overload. Арап from possible damage to the amplifier this can and does damage loudspeakers. In this respect, an overdriven low powered amplifier is much more likely to cause damage than a properly used high powered one.
