9. AUDIO EQUALIZATION OF THE CAT 860

The CAT 860 uses a 4-band audio equalizer designed to optimize and fine-tune the microphone sound quality for the classroom. Below are some tips on proper system equalization:

The voice should be natural, very clear and without any audio feedback (ringing)

• Walk the room listening for the overall quality and any feedback that is present

1. Overview

 

• If there is a lot of audio feedback, it is likely the volume is too high. Ensure the volume is at the appropriate level, a second person is helpful to determine this.

If feedback is still present with the audio set at the right level, make the following EQ adjustments:

High pitched ring: lower the 2K and/or 4K adjustment by _ turn

Lower pitched ring: lower the

500 and/or 1K adjustment by _ turn

If you notice the sound is “muddy” or has too much bass:

Lower the 500 adjustment by _ turn and/or

Raise the 2K or 4K adjustment by 1/8 turn

Note: the EQ adjustments should be preset at “12:00.” This is the nominal level and any adjustments (up or down) should be made from this level.

2.Determine the size and type of audio input jack on the device as many manufacturers’ products differ in connector size and shape. The Lightspeed LES-370 Personal FM System requires a 3.5 mm to 3.5 mm patch cable (part# CA- MMC3535, not included).

3.Connect a patch cable from the ALD’s microphone jack or AUX input to one of the following 3.5mm audio jack on the CAT 860:

“ALD OUT” on the front panel

“AUX OUT” on the back panel

4.Adjust the volume control on the ALD’s receiver to maximum output. NOTE! This is to set the maximum allowable signal from the CAT 860.

5.With the CAT 860 and ALD turned on, speak into the REDMIKE and slowly adjust the corresponding volume control on the CAT 860 until the appropriate audio level is obtained in the ALD.
