Setting Input Level

Testing the output voltage of the source unit
before selecting the input level setting is highly
recommended to determine whether the KEYLOC
needs to be in HI or LO level input mode. In general, if
your input signal is coming from the audio source unit
use the LO Level Input Sensitivity setting, or if your
input signal is coming from a factory amplifier use the
HI Level Input Sensitivity setting. The LO range can
accept 250mV-10V. The HI range can accept 1V –
40 V. If no tools are available, please go to page 16. If
you're not sure what the output voltage is, please use
the following process:
Testing Audio Source Output Voltage: This will
tell you whether to set the INPUT level setting switch
to HI or LO. This can be done with a voltmeter as
used above or an oscilloscope.
To use a voltmeter, change the setting on the meter
to measure AC Voltage. Connect the positive lead
of the meter to the speaker + and the negative lead
to the speaker –. Turn the source unit up to max
volume playing a O dB sinewave test tone. Because
factory source units have equalization applied to
their outputs not every frequency will have the same
output voltage. Because of this, we suggest doing
this test with a 20Hz - 20kHz sweep track. This track
will sweep from 20Hz to 20kHz to let you find the
highest voltage over the entire audio band and can be
