Applications
Here are four suggested applications for the PL 2404; bear in mind that your particular circumstance may dictate
changes in these suggested signal connections and routings.
Application 1 - Using The PL 2404 As A Recording Mixer
The PL 2404 is optimized for use as a recording mixer with multitrack digital or analog recorders. As shown in the
illustration below, microphones and line level signals are connected to various channel inputs. Signal processors are
connected to Aux sends and returns and to channel inserts as required. The Control Room outputs are connected to a
power amplifier driving studio monitors. The Main outputs are connected to the inputs of a two-track or DAT recorder,
with the outputs of the two-track or DAT recorder connected to a PL 2404 stereo channel. The four Bus outputs are
connected to the inputs of a multitrack recorder, with the multitrack outputs connected to two PL 2404 stereo channels.
During mixdown, those channels carrying the multitrack outputs are routed to bus 1/2 (via their channel “Mute 3/4”
switches), with buses 1 and 2 routed to the Main L/R outputs (by pressing in their Bus “L/R” switches). To listen back to
the mix, the channel carrying the two-track outputs is routed to bus 3/4 (via its channel “Mute 3/4” switch); then simply
connect buses 3 and 4 to the Control Room outputs by pressing in their Bus “L/R” switches.
