DDI-8c DataPort Accessory Card
Product Description
The DDI-8c DataPort Accessory Card is specially designed for cinema applications using QSC DCA Series amplifiers, a BASIS processor, and a DSP-30 loaded with a cinema bypass preset.
When wired to a DPDT switch as shown in Figure 1, it allows the projectionist or operator to switch the amplifier inputs over to auxiliary audio sources, fed by a DSP-30, in the event of a failure of the BASIS unit. See Figure 3 for a block diagram of the backup system arrangement.
The DDI-8c DataPort Accessory Card mounts to the back of any two-channel QSC DCA Series power amplifier. Two small LEDs near the right edge of the its circuit board indicate when the auxiliary inputs are enabled.
