4. if any wires are placed inside walls or ceilings they may be required to be fire rated Always check with local building officials Regardless of the brand or type of speaker wire chosen we suggest that you use a wire constructed of multi strand copper with a gauge of 16 or less the lower the number the thicker the cable 16 gauge wire may be used for runs up to 33 10 m 14 12 gauge wire is recommended for longer runs We do not recommend that you use any wires with an AWG equivalent of 18 or higher due to the power loss and degradation in performance A detachable plug is provided for each stereo channel output Strip approximately 6 mm of insulation from the end of each speaker wire and carefully twist the strands of each conductor together Be sure not to cut the individual strands or twist them off All strands must be used for optimal performance Insert the wire into the plug and screw the screws very tight Inspect that there are no stray wire hairs that can short circuit in the plug Outer Jacket Foil Shield Ripcord Correct polarity connections are important to maintain proper speaker phasing When speaker phasing is correct all speakers move in and out at the same time preserving the imaging and bass response of the program material Run the wires to speaker locations Do not coil any excess cable as this may become an inductor that creates frequency response variations in your system Last

10. AT IS IT D BIX Remote Input Wall Plate Cat5 is a very reliable wire The BIX and BIB remote input wall plates use a home run of cat5 wire We use cat5 connectors terminated to the T568A protocol It is strongly recommended to adhere to this standard Speaker Connectors We use a detachable connector sometimes called a phoenix connector There are four connectors included with the Q450rs Each connects one stereo zone WHO IS IT FOR The Q450rs is a four source four zone multi room controller amplifier in a small efficient package It is much like having four integrated hifi amplifiers hidden away from sight and connected together for a seamless listening experience It is equally comfortable at home as it is scaled up using the controlled audio outputs for larger installations such as art galleries or coffee shops The Q450rs is controlled by RS232 commands There is also a wall plate keypad controlled version available model Q450 The balanced input wall plates BIX are a feature we are very proud of and we hope you will agree The BIX plate allows the Q450 to have an input from a room or space far away from the Q450 without any drop in signal quality and best of all without any added unwanted hum and noise This is an industry first Let s put this another way Say you are enjoying a dip in the tub Wouldn t it be nice to be able to plug in your iPod beside the tub and not have to run to the amp to
