Specification Sheet

Tech Tips:
1. If you have an issue go back and review the full manual it has all the info you will need to run
the KEY process.
2. If you have issues getting a smoothed EQ response on an RTA or it just doesn’t sound smoother,
PLEASE MAKE SURE THE SOURCE UNIT IS NOT CLIPPING. WE HAVE SEEN UNITS THAT WILL
CLIP BEFORE ½ VOLUME. IF YOU HAVE AN O-SCOPE, USE IT WITH OUR GAIN MATCH TRACK
TO WATCH THE SWEEP FOR CLIPPING. THEN TURN DOWN THE SOURCE UNIT UNTIL CLIPPING
GOES AWAY. Then go back and check the input GAIN match of the KEYLOC. If there are tall
peaking filters, it can take two or three sweeps of the gain match track to be sure you have gain
matched (wait 10 – 15 seconds to make sure the gain match LEDs are not flashing). If you’re still
seeing an issue where the frequency response is not being smoothed, it is suggested to turn the
input gain down ~¼ of a turn and run the KEYLOC setup process.
3. If step two does not fix your issue, it is very likely that you are clipping the outputs of your audio
source. Use the gain sweep track and an O-scope to verify that the signal coming into the
KEYLOC is not clipping. If it is, turn down the volume on the source unit.
4. In most systems people will not be using a fully active DSP after the KEYLOC. In these cases, you
would likely want to turn off the All-pass/Time-delay defeat for the best imaging. To do these
please refer to the manual for the menu options.
5. To keep the noise floor low (hiss), we have designed the KEYLOC to add no more than 18dB of
gain to any one frequency. In most applications this should get you back to completely smooth
response +/-1.5db in the frequency bandwidth you are feeding into the KEYLOC.
6. During the KEY process, if you accidently push the KEY button before playing the noise floor
track, the KEYLOC will have an error and the LEDs will all flash. You must then press the KEY
button to exit the KEY process. You will need to re-enter the KEY process to start again.
