Samson MPL 1502 User Manual

13
Setting up your MPL 1502 is a simple procedure which takes only a few minutes:
1. Remove all packing materials (save them in case of need for future service)
and decide where the unit is to be physically placed—it can be used on a table-
top or optionally mounted in any standard 19” rack, requiring six rack spaces.
2. Before even plugging the unit into an AC socket, begin by connecting the
MPL 1502 main outputs into a power amp and the amp into loudspeakers. It is
never a good idea to power up any amplifier that is not connected to loud-
speakers.
3. Next, make the signal input connections to the mic or line inputs of the vari-
ous channels.
WARNING: Do not connect a channel’s line input if you already
have something connected to its microphone input, or vice versa; each channel
is designed to accept only one source or the other.
4. Turn all channel trim and gain controls as well as the Main gain control fully
counterclockwise, to their “-∞” setting. Then connect the EEC main power cord
and plug the MPL 1502 into any grounded AC socket.
5. Turn on the rear panel Power switch—the “Power” LED in the meter section
will light up.
