1: Power on-off switch - As you may have guessed, this is what you use to turn the
PL 2404 on and off. To avoid potential damage to your speakers, turn the PL 2404 on
before you turn on any connected power amps—and turn it off after the power amps are
turned off.
2. Fuse - Contains a 1 amp, 250 volt fuse.
3. AC input - Connect the supplied standard 3-pin “EEC” plug here.
4: Bus out (1 - 4) - These unbalanced outputs allow you to route signal from each of the
four discrete buses to external devices such as a multitrack digital or analog tape
recorder. The signal is post-bus fader but pre-Main control. See the “Busing,
Submixing, and Channel Muting” section in this manual for more information.
5: Main Out (L, R) - These are the PL 2404’s main outputs. In live performance
applications, you’ll usually use these to connect the PL 2404 to a power amp and
speakers; in recording applications, these will normally be connected to the inputs of a
two-track recorder. The Main out jacks are electronically balanced, so you should use
balanced three-conductor cabling and 1/4" TRS plugs wherever possible (unbalanced
two-conductor plugs can also be inserted into these outputs, but you’ll get better signal
quality and less outside noise and hum if you use balanced lines). See the “Connecting
the PL 2404” section on page 10 for more information.
6: Control Room Out (L, R) - In recording applications, these will normally be
connected to a power amplifier and loudspeakers. The Control Room out jacks are
electronically balanced, so you should use balanced three-conductor cabling and 1/4"
TRS plugs wherever possible (unbalanced two-conductor plugs can also be inserted into
these outputs, but you’ll get better signal quality and less outside noise and hum if you
use balanced lines). See the “Connecting the PL 2404” section on page 10 in this
manual for more information.
