From the Manufacturer
The PADO4a amp panel allows for connection of loudspeakers, input signal and output signal loop through and is suitable for use with 4 LA48a power amplifiers. The panel has 2 x female 8-pin CACOM connectors for loudspeaker connection; 2 x male 19-pin CA-COM connectors for input signal connection and jumping to subsequent amp racks; 2 x 37 pin D-SUB connectors for attaching COMB connectors that are used to configure the amplifier rack for 2-WAY, 3-WAY or SUB operating modes. Internally, two sets of 4x male XLR fanouts connect the input signal from the COMB connector on PADO4a to the amplifier inputs and two sets of 4x NL4 Speakon line connectors connect the A and B channel amplifier outputs to the two front panel 8-pin female CA-COM connectors. For the 19-pin CA-COM connectors, line 1 is reserved for subwoofer drive; lines 2, 3 and 4 are for VDOSC low, mid and high, respectively; lines 5 and 6 are assigned to 2-way fill (low and high, respectively). The V-DOSC PADO2a amp panel is suitable for use with 2 LA48a power amplifiers and allows for
connection of loudspeakers, input signal and output signal loop through. The panel has a single female
8 pin CA-COM connector for loudspeaker connection that is in parallel with 4 x Speakon NL4
connectors; 2 x male 19-pin CA-COM connectors for input signal connection and jumping to
subsequent amp racks; 1 x 37 pin D-SUB connector for COMB connector attachment that allows the
user to reconfigure the amplifier rack for 2-WAY, 3-WAY or SUB operating modes.
In 3-WAY mode, V-DOSC enclosures are connected via the 8-pin CA-COM connector using DO7 or
DO25 cables. In SUB mode, SB218 enclosures can be connected via the four individual NL4 Speakon
connectors (using SP7 or SP25 cables) or via the 8-pin CA-COM connector (using DOSUB and
optional DO10P cables). In 2-WAY mode, dV-DOSC or ARCS enclosures can be connected via the
lower 2 x Speakon NL4 connectors (using SP7 or SP25 cables) or, alternatively, via the 8-pin CACOM connector (using DO2W cables directly or DO7 / DO25 cables plus DOFILL adapter).
