AudioControl DQX manual Troubleshooting

AudioControl®

there are some crazy folks that prefer their bass substantially louder. The key in this area is to have enough speakers and power to produce the amount bass you desire but don’t use the controls on the DQX to try and force your speakers to produce sounds they can’t. Too much bass boost creates a condition called “speakerus explodus”, which is not pretty to hear or watch.

Midbass: 100 Hz to 300Hz - The phrase, “too much of a good thing” can certainly apply to the midbass frequencies. This is the transition area of the audio spectrum that is an octave above your sub-bass frequencies and several octaves below your midrange. Most autosound systems have too much mid-bass due to the fact that speakers mounted in the doors or kick panels cause resonance’s or peaks in the response curve. These peaks in the mid-bass can actually mask or block sounds in the all-important midrange area causing your system to sound dull and lifeless.

Midrange: 300Hz to 3kHz - Musical instru- ments, vocals, mid-range percussion and many things we associate with imaging and staging happen in this area of the bandwidth. For that reason you will want to keep this area as smooth and balanced as possible. Too much boosting can make you feel like you are listening to your sys-

tem in a tile bathroom. Not enough energy in the midrange sounds empty and dry.

Treble: 3KHz and Up - If midrange is the cake, then these high or upper frequencies are the frost- ing. Many autosound systems start a gradual decline in this area which is why speaker placement is very important. The DQX only gives you a few controls in this area because too much boosting can really make a speaker sound unnatural.

TROUBLESHOOTING

No Power: If the Power LED on your DQX will not turn on, check to make sure that the power wire and remote turn-on wires are connected or a fuse has not blown.

System Sounds Unbalanced: Check your graphic and parametric equalization settings to make sure that one channel is not dramatically different than another.

Sounds Distorted: Should your system sound distorted or your speakers are moving way too much, you should make sure you have your levels matched properly and that your amplifier gains are set at minimum. If this checks out okay, you will want to look at your EQ controls to insure that your boost levels are not overly boosted.
