3. adjust the angle Note While adjusting the angle you will want to place the mic in a position that is least likely to interfere with your playing style Because of the QTOM s pick up pat tern and due to a phenomenon called prox imity effect slight adjustments of the micro phone position and angle can make a big difference in sound For further information on positioning your microphone see the sec tion Microphone Placement and Tone Quality on page 5 of this manual e Connect the QTOM using a standard XLR mic cable and dress the wire away from your drum using the cable strain relief Note For more information on wiring and mic cables see page 7 in this manual Using the QTOM Microphone Placement and Tone Quality When you mount the QTOM to your drum it will be easy to get a great sound since the mic is positioned so close to the sound source You can make slight adjust ments to the height and angle that will have an effect on the sound The changes in sound may be difficult to notice at first especially in live sound applications how ever the more you use your microphone and listen to the sound the more you will understand and hear the effect the microphone placement has on the sound As always experimentation and experience are the best teachers Obviously in live sound applications you can t always hear the final results of the sound you re get ting because most of the time your drum kit will be positio
4. by the QTOM as shown in the illus tration below For this reason the QTOM excels in environments where there is a good deal of unwanted ambient sound it delivers those signals originating directly in front of the mic capsule itself while rejecting those that originate from behind The polar pattern also determines how prone a particular mic is to inducing feed back Feedback is that characteristic nasty howling sound that occurs when a mic is placed too close to a loudspeaker the signal from the loudspeaker is fed into the mic then into the loudspeaker then into the mic over and over again until an oscillating tone is generated Because the cardioid pattern utilized by the QTOM is so good at rejecting signal not coming from directly in front of the mic you ll find that use of the QTOM greatly minimizes feedback problems 180 QTOM Polar Pattern QTOM Frequency Chart 6 QTOM Specifications The QTOM can be connected to any mixer mixer amplifier or mic preamp using a standard microphone cable As shown in the wiring diagrams below connect the female XLR end directly to the QTOM s gold plated connector and the other end normally a male XLR end although some mixers use 1 4 connectors to the mixer mixer amplifier or mic preamp Hot 2 Hot 2 Common 1 Solder rine Eare Tor e 0O End View i 7 l ix EN Von 0l Aa Male XLR Female XLR Hot 2 Tip Hot Hot res aS Male Ph

7. ned behind the PA speak ers so rely on a band mate or sound engineer to help you dial up the sound In recording applications print some scratch tracks and check the sound by listening to your headphones and to the control room monitors By the way the Golden Rule of getting a great sound miking any instrument with any micro phone is to start with a great sounding instrument Be sure that you pay careful attention to the tuning and if necessary the dampening of your drum Miking your drum is similar to put ting the sound under a microscope Any unwanted buzzes and rattles coming from your instrument may be much more noticeable when you mic the drum You ll get a great sound just by mounting the QTOM to your drum however there are some basic principles and fundamentals that should be followed If not at least understood e The QTOM has a cardioid pick up pattern which means it picks up sound directly in front of the microphone and rejects the sound directly behind the microphone This means in order to get the best separation between the sound you want to pick up in the mic for example your tom tom and the ambient sound around it let s say your cymbals or other toms you can aim the mic so that it is facing away from the cymbals or other toms As with any drum miking situation you ll have to make some compromises with the ultimate position for sound and interface to your playing style For more information on polar patte
8. rns see the section Polar Pattern on page 6 of this manual e All microphones especially uni directional or cardioid microphones exhibit a phenomenon known as proximity effect Very simply put proximity effect is a resulting change in the frequency response of a microphone based on the position of the mic capsule relative to the sound source Due to the result of the proximity effect slight adjustments of the microphone position and angle can make a big difference in sound Specifically when you point a cardioid mic directly at the sound source on axis you will get the best frequency response however when you start pointing the microphone slightly away off axis you will notice the low frequency response dropping off and the micro phone will start to sound thinner Knowing that the bass will decrease as you change the mic angle can be a big help if you are getting a boomy sound from your drum QTOM Characteristics Every microphone has a characteristic polar pattern that determines how well it accepts or rejects signal coming from various areas around the microphone For example omnidirectional mics accept all signals regardless of wherever those signals originate in front of the mic behind it to the side etc In contrast directional cardioid mics are specifically designed to accept mostly signal coming from directly in front and to reject signal coming from behind or from the side The cardioid pattern is utilized
