17 LOW
If you turn this control up, you will boost all frequencies below 80 Hz. You will
give more punch to bass drums and bass guitar; and you will make the male
vocalist more "macho". Turn it down and you will cut all the frequencies below
80 Hz. In this way you can avoid low-frequency vibrations and resonance thus
preserving the life of your woofers.
MASTER SECTION

IN signals will be sent to this control.

21 OUTPUT LEVEL METERS
These consist of two column of 8 LEDs
each ranging from -30 dB to +18 dB
(CLIP). The 0 LED corresponds to a level
output of 0 dBu. The CLIP LEDs come
to life when the output reaches +18 dBu.
Set the MAIN MIX level control so that the CLIP LEDs only flashes occasionally.
In general, you get a good mix level when the Meter LEDs operate in the range
0 to +6. If you exceed +6, you will get distortion. If even -30 LEDs are sleeping
your signal-to-noise ratio will suffer.
