Boat Talk to add comments! Welcome to Enforcer R. Hello, you need to enable JavaScript to use Enforcer R. Check connections from receiver or preamplifier.
B Power switch is turned off. A Signal is present, but input level control is set at minimum. A Input level control is set too low. B If using high level inputs, right and left channels are connected out of phase. Check wiring. A Volume of subwoofer is too high, causing amplifier to be over driven. Reduce setting of input level control. B Signal from receiver, amplifier, or preamplifier is distorted from being over driven. Reduce main system volume or bass tone control. C Subwoofer electronics are defective.
A Signal from receiver, amplifier, or preamplifier is distorted from defective electronics. B Signal connecting wires to subwoofer are shorted. A Grounding problem or ground loop condition. B Isolate problem by removing all connecting cables and turning up subwoofer input level control. If noise is still present, subwoofer electronics are defective. As you do, here are some hints for getting the most out of your subwoofer. If more bass is desired, advance the bass or loudness controls on your main amplifier or receiver.
When there is no signal present after a few minutes, the electronics will again shut down to the standby mode. We do suggest that you turn the subwoofer off by its power switch if it is to be unused for an extended period of time. For additional protection against damage from lightning, we recommend unplugging the line cord. C The tone controls on your preamplifier, receiver, or amplifier should be used with caution and care. Excessive boost in certain frequency ranges can cause heavy demands on amplifier and loudspeaker components resulting in overheating, distortion, mechanical overload, and premature failure.
Your new subwoofer is one of the most exciting home entertainment electronic products available, adding impact and realism to recorded music and the wide variety of movies to be found on videotape, laser disc, DVD and offthe-air broadcasts. After you have selected an initial location for your subwoofer and have connected it into your system, have a seat in your normal listening position and have someone help you with the following adjustments: Once set-up and properly adjusted, it should give you many years of entertainment pleasure.
Your subwoofer is a high value product built using the latest materials, technology, and equipment by MTX, a vertically integrated company.
Thank you for selecting MTX in making your audio equipment purchase. Special low noise vents are used for less distortion at the bottom of the frequency range.
C Turn off the loudness control and set the bass tone control on your main amplifier to the flat position. D Use familiar program material that has substantial bass content and play your main system at a moderate volume level.
E Slowly rotate the subwoofer level control clockwise until a good balance is achieved between the low frequency output of your subwoofer and the mid bass and upper frequencies from your main speakers. Leave the switch in the position that gives the highest output level. G Slowly rotate the subwoofer crossover frequency control clockwise to attain the best blend between the level of the subwoofer and the main speakers in the midbass crossover region.
Refer to Figure E. Check the condition of your unit, reporting any damage which may have occurred in transit to your dealer or shipping company. Preamplifier Crossover xover - an electrical filter with lo-pass or hi-pass characteristics that divides the frequency range into bands of low, middle, or high frequencies to match the capabilities of specialized loudspeakers like subwoofers that are only effective at reproducing limited frequency ranges.
The crossover frequency is the frequency where the filter begins to attenuate or reduce the level of the signal. SUB Hi-pass - a type of filter circuit that allows high frequencies to pass, while reducing the level of low frequencies with the transition from high to low occurring at the crossover frequency. The rate of reduction of the signal is called the attenuation rate or slope and is measured in decibels dB over a change in frequency of one octave, which is a doubling or halving of frequency.
Impedance - the resistance to the flow of current in an alternating current circuit such as with music. Line level circuits are typically a high impedance of several thousand ohms, while speaker level circuits are usually a low impedance of a few ohms.
Line level - the type of signal produced at the outputs of preamplifiers, tape decks, CD players, etc. Sometimes called low level signals, they are routed using shielded cables which are usually terminated with RCA phono connectors. FIGURE E Lo-pass - a type of filter circuit that allows low frequencies to pass, while reducing the level of high frequencies with the transition from low to high occurring at the crossover frequency.
The rate of reduction is called the attenuation rate or slope and is measured in decibels dB over a change in frequency of one octave, which is a doubling or halving of frequency.
