APPLICATIONS
‘Square’ Room Combining
Programming of the PMX84 for this application can be done by simply opening & downloading a file (square1a.pmx) during Configuration.
This application shows (4) rooms in a ‘square’. Each room has (2) mics & (1) auxiliary input connected to an Advantage 301e. The 301e
mic/line mixers provide mixing, remote level control, auto-muting of aux inputs, and balanced line-level outputs for Rooms 1~4. The 301e
outputs for Rooms 1~4 are then connected to Inputs 1~4 of the PMX84, respectively. Outputs A~D of the PMX84 are connected to inputs
of Advantage D60EQs for Rooms 1~4, respectively. The D60EQs provide amplification, equalization, & transformer output necessary for
the distributed speakers in each room. CMA mixer/amplifiers may be used instead of the 301e mixers & D60EQ amplifiers. A switch on
each room partition is wired to the appropriate Logic Input on the PMX84 (see diagram at bottom of page). The Logic Inputs are
programmed for a ‘binary’ (room combining) mode. This allows the PMX84 to recognize the various room combinations, by reading the
status of all four room partition switches. The Logic Inputs are also programmed to perform the input/output assignments associated with
the various room combinations. Twelve practical room combinations are available: 1 / 2 / 3 / 4; 1+2 / 3 / 4; 1 / 2+3 / 4; 1 / 2 / 3+4; 4+1 /
2 / 3; 1+2+3 / 4; 1 / 2+3+4; 1+3+4 / 2; 1+2+4 / 3; 1+2 / 3+4; 1+4 / 2+3; and 1+2+3+4. Whenever a single room partition is closed (no
rooms isolated), the PMX84 is programmed to assume all rooms are combined (1+2+3+4).
