Adjusting the channel volume and channel EQ using the Peak In-
dicator:
The PEAK indicator will
light up green when it
senses that there is a sig-
nal present on the input connector. You can adjust the channel
LEVEL control up or down to achieve the desired volume relative
to the other channels. As long as the Peak indicator remains
green, the signal is being amplified and mixed appropriately to
provide clean output sound.
The PD–500 provides a
mechanism to get the
maximum level from each
channel without distorting the signal. Play your program mate-
rial, or speak into the microphone and slowly increase the chan-
nel volume and EQ levels until the peak indicator occasionally
flashes red. It will be easiest to adjust the EQ to the desired lev-
els at lower volume, and then increase the channel volume to
the optimal waveform.
The peak indicator will be
solid red if you raise the
channel volume too high.
This indicates that the signal is over-amplified. Turn the LEVEL
control down to prevent the signal from being clipped and dis-
torted. Too much clipping can be aurally unpleasant as well as
potentially dangerous to your speakers.
• LEVEL - Adjusts the volume level for each channel.
Use in conjunction with the Master Volume controls.
If the LEVEL control is up too high, the PEAK indica-
tor will light up red.
• PEAK INDICATOR – The PEAK indicator will light up green when
there is a signal present. Reduce LEVEL if the PEAK LED illumi-
nates red, which indicates that the signal may be clipped.
• FX SEND - Adjusts the effects level for each chan-
nel. Use in conjunction with the Digital Effects FX
LEVEL master control.
• MONITOR - Adjusts the Monitor volume level for
each channel. Use in conjunction with the master
Monitor Level control at the MONITOR OUT jack.
• PAN/BALANCE -Use the PAN control (BALANCE for
channels 7–8) to adjust the amount of signal sent to
each speaker (left & right). Adjusting this control al-
lows you to adjust the position of the sound source
within the horizontal plane, left or right of center stage. Set to
the center dot for equal amounts to the left and right speakers.
• HIGH and LOW - These EQ controls allow the user
to boost or cut the bass and treble for the individual
channel. Start with the channel EQ controls in the
center position, then adjust only as much as needed
to sound good. (To adjust the sound for all channels,
use the System EQ controls.)
• PHANTOM POWER - For condenser micro-
phones that require “phantom power” press this switch IN.
• MIC INPUT - This three pin XLR balanced female in-
put connector can accept high- and low-level micro-
phone inputs, and also balanced line inputs. Phan-
tom Power will be applied to the XLR connector if the
Phantom Power switch is on and the MIC/LINE switch
is in the MIC position.
• 1/4" PHONE JACK INPUT - This 1/4" balanced mono input jack
is capable of accepting high– or low–impedance microphones,
keyboards, drum machines, outboard effects, etc.
• MIC/LINE SWITCH - Set this switch to the MIC position for
low–impedance microphones, phantom powered microphones,
and very low-level input signals. Set the switch to the LINE po-
sition for high–impedance microphones and high–level signals. Al-
ways turn down the corresponding channel level control before
pressing the MIC/LINE switch to prevent a loud outburst.
