1.8 dV-DOSC AMP PANELS
The PADO4a amp panel allows for connection of loudspeakers, input signal and output signal loop
through and is suitable for use with 4 LA24a or LA48a power amplifiers. The panel has 2 x female 8-
pin CA-COM 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 to configure the amplifier rack in 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, channel assignments are as follows:
3-way stereo format presets: Line 1 is reserved for dV-SUB, SB118 or SB218 subwoofers (SUB(A)
COMB connector); lines 2 and 3 for dV-DOSC low, dV-DOSC high (2W(A) COMB connector); Line 4
for dV-SUB, SB118 or SB218 subwoofers (SUB(B) COMB connector); lines 2 and 3 for dV-DOSC low
and dV-DOSC high (2W(B) COMB connector).
4+2 format presets: Line 1 is reserved for SB118 or SB218 subwoofer drive (SUB COMB connector);
lines 2, 3 and 4 are for dV-SUB, dV-DOSC low, dV-DOSC high, respectively (3-WAY COMB
connector); lines 5 and 6 are assigned to 2-way fill (low and high, respectively).
5+1 format presets: Line 1 is reserved for SB118 or SB218 subwoofer drive (SUB COMB connector);
lines 2, 3 and 4 are for dV-SUB, dV-DOSC low, dV-DOSC high, respectively (3-WAY COMB
connector).
The PADO2a amp panel is suitable for use with 2 LA24a or 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, dV-DOSC and dV-SUB enclosures are connected via the 8-pin CA-COM connector
using DO7 or DO25 cables and the DO3WFILL adapter cable. In SUB mode, SB118 or 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 2-way fill enclosures (ARCS, 112XT, 115XT, 115XT HiQ) can be connected via
the lower 2 x Speakon NL4 connectors (using SP7 or SP25 cables) or, alternatively, via the 8-pin CA-
COM connector (using DO2W cables directly or DO7 / DO25 cables plus DOFILL adapter).
