26. HI-Z SWITCH (Ch. 7 and 8 only)
Engage this switch if you want to connect a guitar
directly to the 1/4" inputs of channels 7 or 8.
Without this switch, you need to use a DI box fi rst,
before connecting guitars directly. If these switches are
not pressed in, guitars will not sound good, particularly
the high frequency response.
CHANNEL EQUALIZATION (EQ)
The PPM1012 mono channels have 3-band equaliza-
tion: low shelving, mid peaking with adjustable frequen-
cy, and high shelving. The stereo channels have 4-band
EQ: low shelving, low-mid and high-mid peaking, and
high shelving.

Shelving EQ means that the circuitry boosts or cuts
all frequencies past the specifi ed frequency. For exam-
ple, the low EQ boosts bass frequencies below 80 Hz and
continuing down to the lowest note you never heard.
Peaking EQ means that certain frequencies form a "hill"
around the center frequency.
With too much EQ, you can really upset things. We've
designed a lot of boost and cut into each equalizer
circuit, because we know that everyone will occasion-
ally need that. But if you max the EQ on every channel,
you'll get mix mush. Equalize subtly and use the left
sides of the knobs (cut), more than the right (boost).
If you fi nd yourself repeatedly using full boost or cut,
consider altering the sound source, such as placing a
mic differently, trying a different kind of mic, changing
the strings, or gargling.
