46. Power Amp Control Switches
These switches control the activity and the
strength of the power amp. Using the left
switch can alternate between the different
signals which can be processed by the built-
in power amp and routed to the main speaker
outputs on the rear of the device. This switch
allows you to select from: Stereo, the final
level of which is adjusted by the MAIN L/R
fader; AUX 1/MONO, the final level of which
is adjusted by the AUX 1 fader and MONO
fader; AUX 1/AUX 2 outputs, the final level of
which is adjusted by the AUX 1 and 2 faders,
and; MONO BRIDGE, which is output via professional speaker
output A only, and the volume of which is controlled by the
MONO fader.
NB. When using a mono bridge connection, do not connect a speaker to
either the 1/4" phone jacks, or the professional speaker jack B speaker
connector, located on the rear of the mixer.
The amplification power can be changed using the right switch
from 100 Watts for each channel, to 300 or 500 Watts per
channel on the K-12 Plus and K-16 Plus only, the selection of
which will depend on the size of a venue and the input capacity
of the speakers you have chosen to use. This feature is not
included in the Powerpod 1860 Plus.
47. Solid Phonic System (K-16 Plus only)
Using this switch (featured on the K-16 Plus only) will enable the
user to give both the high and low frequencies of their sound a
little boost to improve the overall robustness of the audio. There
is no guarantee your sound will improve with the sPs activated,
however, so it’s probably desirable to audition the mixer’s sound
with this switch on and off, and decide which is better for your
purposes.
48. Graphic Equalizer
This stereo 7 band graphic equalizer allows users to adjust the
frequency response of a signal, with a maximum of 12 dB of
boost or cut for each of the frequencies. The AUX 1 / L/R button
alternates the use of the equalizer between the AUX 1 bus and
MAIN L/R bus signals, accordingly. When L/R is selected, the
equalizer is applied to not only both the main stereo signal (Main
and Speaker outputs), but also to the mono signal. Pushing the
on button in activates the equalizer, which is accompanied by
an illuminated LED.
One feature, built into the Powerpod K-12 Plus and K-16
Plus's graphic equalizer, is a Feedback Detection System.
The individual LEDs located on the sliding VR controls of the
equalizer will illuminate when feedback occurs on that particular
frequency band. By reducing the level of that frequency band
you can quite effectively remove the feedback on that frequency;
after which the LED will turn off. If the FBD button is pushed
in, the feedback detection is active for the final AUX 1 signal,
whereas if it is released, the feedback detection is active for the
MAIN L-R signal. It is recommended that users switch the the
AUX 1 / L/R button to the same setting as the FBD button, as to
ensure simpler adjustment of frequencies that have produced
feedback.
49. Stand-by Switch and Indicator
This switch enables and disables a mute of channels 1 through
to 15/16 on the K-16 Plus, and channels 1 through to 11/12
on the K-12 Plus and 1860 Plus. This feature is handy in live
performances, due to the fact that the Tape In and stereo AUX
Returns are not muted when it is activated, allowing an audio
signal from CD players or other input devices to be played
during performance breaks, while still ensuring microphones
fail to produce hideously sounding feedback (as opposed to
feedback that actually sounds good, of course). Pushing of the
stand-by switch is accompanied by an illuminated LED.
50. Phantom Power Switch
When this switch is in the on position it act48V of
Phantom Power for channels 1 through to 8 on the K-12 Plus,
and channels 1 through to 12 on the K-16 Plus, allowing
condenser microphones to be used on these channels.
Activation of Phantom Power is accompanied by an illuminated
LED on these two models. On the Powerpod 1860 Plus, this
switch has 3 positions, allowing users to activate phantom
power for channels 1 through 8, channels 1 through 4 only, or
no channels at all.

51. Stereo Return Controls
These controls are used to adjust the
audio level that is received by the stereo
return input jacks. They consist of 2
auxiliary level controls, for adjusting the
level to be sent to the auxiliary mixing
bus, and a level control, for adjusting
levels to be sent to the main mixing
bus.
The corresponding PFL (Pre-Fader
Listen) buttons allow you to send
the audio of the stereo return inputs
directly to the CTRL RM/PHONES
control, unaltered by any level controls.
Activation of the PFL is accompanied
by an illuminated LED. 51
