3. it s a good idea to start with the overhead mics Even though you use the overhead mics mostly for the cymbals try to get the entire kit to sound great in the overheads Then it will be easier to just bring up your individual mics for more attack and thickness in the overall sound Hi Hat The CL2 is a perfect microphone for miking Hi Hats thanks to its smooth top end and the ability to capture fast attack transients Try placing the microphone over the edge of the top cymbal Experiment by moving the mic further over the cymbal to produce more of a stick sound but keep in mind it may pick up more of the kit Remember that the CL2 has a cardioid frequency response so position the microphone in the direc tion of the Hi hat but for increased separation be sure to point the mic away from other drums or cymbals whenever possible Wiring Guide The CL2 can be connected to any mixer mixer amplifier or mic preamp using a stan dard microphone cable As shown in the wiring diagrams below connect the female XLR end directly to the CL2 s gold plated connector and the other end normally a male XLR end although some mixers use 1 4 connectors to the mixer mixer ampli fier or mic preamp Hot 2 Common 1 Common 1 Hot 2 Em End View el Solder Points End View CH Male XLR Female XLR colaa i Cold Hot 2 Tip Han Cold Hot Common 1 Male Phone x

9. he CL2 Most mixers and recorders of reasonable quality will offer a microphone input with mic trim usually called Trim or Gain control The purpose of the mic trim control is to optimize the amount of good signal to any noise associated with the mixers electronics A good mic pre with trim also will have a PEAK or CLIP LED To set a good level on the mic set the CL2 up in front of the desired sound source and slowly raise the mic trim control until you see the PEAK LED light up Then turn the mix trim control down until the LED does not light any more On most mixers the ideal setting is that the trim control is turned up as much as possible without light ing the PEAK LED If you try turning the Gain control all the way down and the PEAK light is still lighting try using the CL2 s PAD as explained in the following section Using the PAD Switch The CL2 includes a PAD switch which you can use to lower the input sensitivity of the microphone When the PAD switch is set at the OdB position the PAD is bypassed and there is no effect on the signal When the PAD switch is set to the 10dB position the microphone s input sensitivity will be lowered by 10dB You can use the PAD when you are miking high SPL Sound Pressure Level or loud sound sources Using the Hi Pass Filter The CL2 offers a user selectable hi pass low cut filter which you can use to eliminate any unwanted low frequency reproduction When the Hi pass Filter is set to the
