TABLE OF CONTENTS Safety Instructions . . 11 3 BPS-400 owners manual INTRODUCTION We are proud to welcome you as a new owner of a Mirage BPS-400. Mirage subwoofers are the result of extensive research into accurate bass reproduction and represent the leading edge in subwoofer design and performance. The finest components and cabinet materials combined with sophisticated manufacturing and quality control procedures ensure many years of exceptional performance and listening pleasure. PLEASE TAKE TIME TO READ ALL OF THE INSTRUCTIONS CONTAINED IN THIS MANUAL TO MAKE CERTAIN YOUR SYSTEM IS PROPERLY INSTALLED AND FUNCTIONING CORRECTLY. Retain the carton and all packing material for future use. FEATURES AND OPERATING CONTROLS All operating controls are conveniently located on the amplifier panel mounted on the rear of your subwoofer cabinet. FEATURES Auto-On/Auto-Off Circuit Your subwoofer is equipped with a special "Auto-on/Auto-off " circuit. This circuit automatically turns your subwoofer on as soon as it senses a program signal. At a predetermined time after the program signal ends, this circuit automatically turns the subwoofer off. Clipping Protection Circuit Many powered subwoofers on the market today produce distorted sounds as a result of clipping at high input levels. Mirage's proprietary Clipping Protection Circuit (CPC) continuously senses the input signal level and automatically adjusts to prevent clipping of the wave form, maintaining undistorted bass reproduction. 4 owners manual BPS-400 Pulse Width Modulation Your new BPS-400 incorporates a revolutionary new power amplifier technology called Pulse Width Modulation (PWM). The 400 watt PWM amplifier used in the BPS-400 has much higher efficiency (90%) than typical analog amplifiers (20%) and thus generates much less heat (typically 1/5). The PWM amplifier can generate much higher power output than comparable analog amplifiers (400W vs 100-200W). The 400 watt PWM amplifier is capable of generating very high sound pressure levels 125dB @ 18Hz. Low-Level RCA Input Jacks The RCA input jacks allow you to connect your subwoofer to any of the following: (a) (b) (c) (d) (e) (f) Pre-amplifier outputs Audio/Video processor outputs The "subwoofer output" from an Audio/Video receiver Any integrated receiver with pre-out facilities The audio output from your stereo television or computer sound cards An External Active Crossover. See "Subwoofer Connection to your Audio/Video System". OPERATING CONTROLS Subwoofer Level Control This rotary control adjusts the output level of your Mirage subwoofer and should be used to balance the level of the subwoofer with that on your main/satellite speakers. See "Set-up Calibration". LP Filter (Low-pass) Control This rotary control adjusts the high frequency roll-off of the subwoofer. Continuously variable from 50Hz to 100Hz, it is used to precisely match the subwoofer bass reproduction with that of your main/satellite speakers.
