Samson MPL 1502 User Manual

Guided Tour - Rear Panel
1: Power on-off switch - As you may have guessed, this is what you use to
turn the MPL 1502 on and off. To avoid potential damage to your speakers, turn
the mixer on before you turn on any connected power amps—and turn it off after
the power amps are turned off.
2: Phantom switch - When this switch is turned on, the MPL 1502 delivers 48
volts of phantom power to pins 2 and 3 of all XLR microphone connectors (mono
channels 1 - 5).
WARNING: Only turn this on or off with the MPL 1502 powered
down. Use phantom power only when one or more condenser microphones are
connected to the MPL 1502 (these microphones will correctly load the input in
order to “drain off” the phantom power voltage). Before turning phantom power
on, be sure to disconnect all non-microphone signal sources (such as direct
injection boxes) from the XLR mic jacks. Phantom power will generally have no
adverse affect on connected dynamic microphones; however,
we strongly
recommend that you refer to the owners manual of your microphone to
determine whether or not it requires 48 volts phantom power. We cannot
assume responsibility if you damage a mic by incorrectly applying
MPL 1502 phantom power.
If you’re not sure that one or more connected mics
require 48 volts phantom power, leave this switch OFF.
3: AC input - Connect the supplied standard 3-pin “EEC” plug here.
4: Voltage selector - Set this to the left (“115 V”) position for operation in the
United States and Canada. Set this to the right (“230 V”) position for operation
in other countries. This will normally be preset correctly at the factory and will
require no adjustment unless you use the MPL 1502 in a country other than the
one in which you purchased the unit.
