Don’t use guitar cords for speaker cables!
They’re not designed to handle speaker-level
signals and could overheat.
Set the levels
It’s not even necessary to hear what you’re doing to
set optimal levels. But if you’d like to: Plug headphones
into the phones output jack, then turn up the phones
knob just a little.
1. Turn on the PPM1012 by pressing the top edge
of the power switch.
2. For one channel, press the solo switch in, and
the rude solo light will turn on.
3. Play something into that input at real-world
levels.
4. Adjust that channel's gain control until the
left main meter stays around the 0 dB LED
(marked "level set").
5. Disengage the channel's solo switch.
6. Repeat steps 2 to 5 for the remaining channels.
7. In normal playing, the channel's OL LED should
only light occasionally. If it stays on for a large
portion of your performance, check that the
gain control is set correctly.
8. Turn up the channel faders to the "U" mark.
9. Slowly turn up the main level fader until you
hear the signals in your speakers.
10. If needed, apply some EQ wisely.
11. Adjust the channel faders to get the best mix.
Keep the gain controls and faders fully down on
unused channels.
Other Notes
• Only connect the powered mixer's speaker-level
outputs to passive loudspeakers.
• For optimum sonic performance, the channel
faders and main mix fader should be set near
the U (unity gain) markings.
• When shutting down, turn off any external
amplifiers first. When powering up, turn on any
external amplifiers last. This will reduce the
chance of turn-on or turn-off thumps in your
speakers.
• Save the shipping box!
Read This Page!
We realize that you must be really keen
to try out your new powered mixer. Please
read the safety instructions on page 2
and this page, and the rest can wait until
you’re ready. But please read it — you’ll be glad you did.
Setup
Make sure there is at least 6 inches of airspace behind
the powered mixer for ventilation. There are two fans
inside to cool the power amplifier section. Use the pow-
ered mixer in a nice clean environment, free from dryer
lint and dust bunnies.
Zero the controls
1. Fully turn down all the faders and controls,
except for the channel EQ, graphic EQ faders,
and pan controls, which should be centered.
2. Make sure all buttons are in the out position.
Connections
1. Make sure the AC power switch is off before
making any connections.
2. Push the linecord securely into the IEC connec-
tor on the rear panel, and plug it into a 3-prong
AC outlet that is properly configured for the
voltage of your powered mixer.
3. Plug a balanced microphone into one of the mic
XLR (3-pin) connectors. Or connect any line-
level signal (keyboard, or guitar preamp) to a
line input jack using a TS or a TRS 1/4” plug.
4. If your microphone requires phantom power,
press in the 48V phantom power button.
5. You can connect a guitar directly to line inputs
7 or 8 without need for a DI box. Press the hi-z
switch on these channels if you do.
6. The insert jacks can be used to connect an
external effects or dynamics processor into the
signal chain. See page 13 for more details.
7. Plug the speakers (4 ohms or greater) into the
speaker output jacks on the rear panel. If you
plug two speakers into a side, each speaker
must be 8 ohms or greater to maintain a 4-ohm
minimum load on the amplifier. Use at least
18 gauge speaker cable with 1/4” TS plugs. For
now, set the power amp mode switch to stereo
mains.
