CAUTION
When tuning the switch on (
mics are connected to the XLR input. Devices other than
condenser mics may be damaged if connected to the phantom
power supply. Note, however, that the switch may be left on
when connecting to balanced dynamic microphones.
To avoid damage to speakers, be sure to turn off amplifiers (or
powered speakers) before turning this switch on or off. We also
recommend that you turn all output controls to their minimum
settings before operating the switch to avoid the risk of loud
noises that could cause hearing loss or device damage.

4) PAD button
If you are using microphone as an input, this button
should be set to "Off" position. If you are using input from
the mixing console or CD player, please set this switch to
"On" position.
5) Input gain level knob
After connecting your microphone, you can set the
input level to reach perfect understanding of lectern's
speech. To achieve the best balance between S/N ratio
and dynamic range, adjust the level so that the CLIP
(25) indicator lights only occasionally and briefly on the
highest input transients.
