Samson manual Applications, Application 1 Using The MPL 1204 As a Recording Mixer

Applications

Here are four suggested applications for the MPL 1204; bear in mind that your particular circumstance may dictate changes in these suggested signal connections and routings.

Application 1 - Using The MPL 1204 As A Recording Mixer

The MPL 1204 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, with Aux send 1 (which is pre-fader) driving a headphone amplifier for cue mixes. 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 the MPL 1204 tape inputs. The four Bus outputs are connected to the inputs of a multitrack recorder, with the multitrack outputs connected to four MPL 1204 channel line inputs. 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 channels carrying the two-track outputs (channels 11 and 12) are routed to bus 3/4 (via their channel “Mute 3/4” switch); then connect buses 3 and 4 to the Control Room outputs by pressing in their Bus “L/R” switches.
