VU METERS
Check that the VU meters indicate "0 VU"
when PGM OUT ( 1 -4) and STEREO OUT

the meters do not indicate "0 VU", adjust VRs
with a slot blade screwdriver inserted into an
access hole located above each meter.

PEAK LEOS
Peak LEOs are preset to l ight at +1 1 VU and
extinguish at +8.5 VU.
I ncrease the input level by 1 1 dB from -10 dBV
to +1 dBV without altering the settings in
paragraph 1 -1 and check to see that the peak
LEOs light at a +1 1 VU reading.
