2. INTRODUCTION Congratulations and thank you for purchasing the MPS-5310. Miller & Kreisel Professional powered subwoofers are designed to provide many years of accurate and problem free operation. We strongly encourage you to read this owner's manual, as there is a great deal of information provided here to help you get the best possible performance from your new M&K Professional subwoofer.
4. QUICK PRODUCT OVERVIEW The MPS-5310 is a 350-Watt powered subwoofer that is certified for THX pm3 applications with reference level output in rooms up to approximately 3000 Cubic Feet in volume (multiple subs can be used for larger room applications). The MPS-5310 features M&K Professional’s exclusive Headroom Maximizer CircuitTM, which allows the fulluncompressed dynamics of the audio signal to be heard up to the subwoofer's full capacity - while preventing amplifier clipping and distortion.
As you walk around the room, be sure to pay careful attention to where the spectral response is smoothest and has the greatest low frequency extension. Pay special attention to the corners and along the walls. Remember, because the subwoofer is basically omni-directional, the best spot for the subwoofer may be next to, or behind, the main monitoring area. After analyzing the data and finding the spot where the subwoofer has the best response in the room, place the subwoofer in that location.
A) Mono Balanced Input - 61K Ohms balanced input connector - 200mv in produces 90dB of output (Reference/THX input sensitivity mode). Pin Polarity: 1. Ground 2. Plus 3. Minus B) Variable Low-Pass Filter - 50Hz to 125Hz, 36dB per octave low-pass filter. This optional adjustment is activated by setting the 3-way toggle switch located to the right of this knob to the center position. C) 3-way Low-Pass Filter Toggle Switch - In the THX position of the switch the low-pass filter of the subwoofer is bypassed.
7. RESPONSE AND SENSITIVITY ADJUSTMENTS The MPS-5310 features user adjustable response, sensitivity and crossover adjustments in order to allow for easy integration into any monitoring system or acoustical space. Make sure to use the settings that best match your specific components so that double filtering does not occur and so that the desired (most accurate) response is achieved.
E. M&K speaker system with an LFE-4 Bass Management Controller or some other form of bass management system. 2. If possible, have one person sit at the listening/monitoring position and read the SPL meter, while another person adjusts the trim pots. The SPL meter should be held at arm’s length at ear height. 3. When the slot of the trim LFE-4/LFE-5 pot is pointing at the top cover, the system gain is approximately 0dB. The Test CD The test CD has three tracks on it to aid in setup.
3. Select CD track #1 and set your SPL meter for C weighting and slow response. Have your assistant sit in the listening position, and hold the SPL meter at armís length and at ear height, pointed towards the speaker at a slight upward angle and read the SPL. Then using a small flat bladed screwdriver adjusts the level trim pot of the LFE-4 until the meter reads 4. Repeat steps 1, 2, and 3 for the other front speakers. 5.
One might ask, won’t I perceive a difference in imaging if the sound of one channel originates from two sources (subwoofer and satellite)? The answer is actually no. Bass Management works by taking advantage of the ear’s inability to determine the direction of frequencies below approximately 150Hz. Provided there is no audible distortion or sonic artifacts at higher frequencies (port noise etc.
Main channel speakers, in a system that has Bass Management, can be small and can be placed where large full range speakers can’t. Unlike two-channel stereo, multichannel audio requires that speakers be placed in very specific locations. In video post it means placing speakers close to the sides and top of the monitor. In Telecine, it means fitting the center channel speaker inside a light cove. In situations where near field monitoring is required, it can mean three speakers sitting on the console.
